The successful development of hermetically sealed refrigera-

tion compressors has completely sealed the compressor's

moving parts and electric motor inside a common housing,

minimizing refrigerant leaks and the hazards sometimes

associated with moving belts, pulleys or couplings.

Fundamental to the design of hermetic compressors is a

method whereby electrical current is transmitted to the

compressor motor through terminal conductors which pass

through the compressor housing wall. These terminals are

sealed in a dielectric material which insulates them from the

housing and maintains the pressure tight integrity of the

hermetic compressor. The terminals and their dielectric

embedment are strongly constructed, but are vulnerable to

careless compressor installation or maintenance proce-

dures and equally vulnerable to internal electrical short

circuits caused by excessive system contaminants.

WARNING

System contaminants, improper service procedure

and/or physical abuse affecting hermetic compressor

electrical terminals may cause dangerous system

venting.

WARNING

To avoid possible injury, explosion or death, practice

safe handling of refrigerants.

SAFE REFRIGERANT HANDLING

While these items will not cover every conceivable situation, they should serve as a useful guide.

In either of these instances, an electrical short between the

terminal and the compressor housing may result in the loss

of integrity between the terminal and its dielectric embed-

ment. This loss may cause the terminals to be expelled,

thereby venting the vaporous and liquid contents of the

compressor housing and system.

A venting compressor terminal normally presents no danger

to anyone, providing the terminal protective cover is properly

in place.

If, however, the terminal protective cover is not properly in

place, a venting terminal may discharge a combination of

(a) hot lubricating oil and refrigerant

(b) flammable mixture (if system is contaminated

with air)

in a stream of spray which may be dangerous to anyone in the

vicinity. Death or serious bodily injury could occur.

Under no circumstances is a hermetic compressor to be

electrically energized and/or operated without having the

terminal protective cover properly in place.

See Service Section S-17 for proper servicing.

IMPORTANT INFORMATION

Refrigerants are heavier than air. They can "push out"

the oxygen in your lungs or in any enclosed space.To

avoid possible difficulty in breathing or death:

• Never purge refrigerant into an enclosed room or

space. By law, all refrigerants must be reclaimed.

• If an indoor leak is suspected, thoroughly ventilate

the area before beginning work.

• Liquid refrigerant can be very cold. To avoid possible

frostbite or blindness, avoid contact with refrigerant

and wear gloves and goggles. If liquid refrigerant

does contact your skin or eyes, seek medical help

immediately.

• Always follow EPA regulations. Never burn refrig-

erant, as poisonous gas will be produced.

WARNING

To avoid possible explosion, use only returnable (not

disposable) service cylinders when removing refrig-

erant from a system.

• Ensure the cylinder is free of damage which could

lead to a leak or explosion.

• Ensure the hydrostatic test date does not exceed

5 years.

• Ensure the pressure rating meets or exceeds 400

lbs.

When in doubt, do not use cylinder.

PRODUCT DESIGN

This section gives a basic description of cooling unit opera-

tion, its various components and their basic operation.

Ensure your system is properly sized for heat gain and loss

according to methods of the Air Conditioning Contractors

Association (ACCA) or equivalent.

CONDENSING UNIT

These units are designed for free air discharge. Condensed

air is pulled through the condenser coil by a direct drive

propeller fan and then discharged from the cabinet top. The

unit requires no additional resistance (i.e. duct work) and

should not be added.

The GSH13, GSH14, ASH13 and VSH13 Heat Pump con-

densing units are designed for 208-230 dual voltage single

phase applications. The GSH13 3 ton model is available in

230V, 3 phase applications. The GSH13 4 and 5 ton models

are available for 230V, 3-phase and 460V, 3-phase applica-

tions.

The units range in size from 1.5 to 5-ton and have a rating of

13 and 14 SEER. SEER efficiency is dependent upon the unit

and its components. Refer to the "Technical Information"

manual of the unit you are servicing for further details.

The GSC13, GSC14 and ASC13 and VSC13 Condensing

Units are made in 1.5 through 5 ton sizes. They are designed

for 208-240 volt single phase applications. The GSC13 3 ton

model is available in 230V, 3 phase applications. The GSC13

4 and 5 ton models are available for 230V, 3-phase and 460V,

3-phase applications.

Suction and Liquid Line Connections

All units come equipped with suction and liquid valves

designed for connection to refrigerant-type copper. Front

seating valves are factory-installed to accept the field-run

copper. The total refrigerant charge needed for a normal

operation is also factory-installed. For additional refrigerant

line set information, refer to the "Technical Information"

manual of the unit you are servicing.

Compressors

GSC13, VSC13, GSH13 and VSH13 use a mix of reciprocat-

ing and scroll compressors, except for the VSC130181AA

which uses a rotary compressor. The ASC13 and ASH13 use

the Copeland Scroll® Compressor. There are a number of

design characteristics which differentiate the scroll compres-

sor from the reciprocating compressor. One is the scroll. A

scroll is an involute spiral which, when matched with a mating

scroll form, generates a series of crescent-shaped gas

pockets between the members (see following illustration).

During compression, one scroll remains stationary while the

other form orbits. This motion causes the resulting gas

pocket to compress and push toward the center of the scrolls.

When the center is reached, the gas is discharged out a port

located at the compressor center.

GSC130361D* and GSC130481AG use Bristol® BENCH-

MARK™ compressors, the most advanced compressors in

the industry today. The BENCHMARK™ reciprocating com-

pressor can be recognized by a “J” in the fourth character of

the compressor model number. Innovative mechanical de-

sign and gas management make the BENCHMARK™ com-

pressor very efficient and remarkably quiet. The sound

content (frequency) delivers exceptional acoustical charac-

teristics and the virtually round housing design is compact

and also helps to reduce the overall sound and vibration.

GSC130181BA use Panasonic® rotary compressors.

COILS AND BLOWER COILS

MBR/MBE blower cabinets are designed to be used as a two-

piece blower and coil combination. MBR/MBE blower sec-

tions can be attached to cased evaporator coil. This two-

piece arrangement allows for a variety of mix-matching

possibilities providing greater flexibility. The MBE blower

cabinet uses a variable speed motor that maintains a con-

stant airflow with a higher duct static.

It is approved for applications with cooling coils of up to 0.8

inches W.C. external static pressure and includes a feature

that allows airflow to be changed by +15%. The MBR blower

cabinet uses a PSC motor. It is approved for applications with

cooling coils of up to 0.5 inches W.C. external static

pressure.

The MBR/MBE blower cabinets with proper coil matches can

be positioned for upflow, counterflow, horizontal right or

horizontal left operation. All units are constructed with R-4.2

insulation. In areas of extreme humidity (greater than 80%

consistently), insulate the exterior of the blower with insula-

tion having a vapor barrier equivalent to ductwork insulation,

providing local codes permit.

The CAPX/CHPX coils are equipped with a thermostatic

expansion valve that has a built-in internal check valve for

refrigerant metering. The CACF/CAPF/CHPF coils are

equipped with a fixed restrictor orifice.

PRODUCT DESIGN

The coils are designed for upflow, counterflow or horizontal

application, using two-speed direct drive motors on the

CACF/CAPF/CHPX models and BPM (Brushless Permanent

Magnet) or ECM motors on the MBE models.

The ARUF is a multi-position air handler (upflow/horizontal or

downflow) and is equipped with a flowrator for cooling and heat

pump applications. Because of its seamless copper tubing

and aluminum fins, there are fewer leaks. The steel cabinet

of the ARUF is fully insulated and rust resistant. Thermal

expansion kits for air conditioning and heat pump applica-

tions are available.

ARPF*B 2 to 5 ton air handlers are dedicated for downflow

operation and are approved for modular homes. Flowrater.

transformer and blower time delay are on all standard ARPF

units. Both the ARUF and ARPF have direct-drive multi-

speed motors.

AEPF is a multi-position, variable-speed air handler and can

be used with R-410A or R-22 (models ending in 1/16). The

unit's blower design includes a variable-speed DC motor and

is compatible with heat pumps and variable-capacity cooling

applications.

ASPF is a multi-position air handler that can be used with R-

410A or R-22 and it features a X-13 motor. This motor is a

constant torque motor with very low power consumption and

it is energized by a 24V signal. The X-13 features an

integrated control module and is compatible with heat pumps

and cooling applications.

SYSTEM OPERATION

COOLING

The refrigerant used in the system is R-22. It is a clear,

colorless, non-toxic, non-irritating, and non-explosive liquid.

The chemical formula is CHCLF2. The boiling point, at

atmospheric pressure is -41.4°F.

A few of the important principles that make the refrigeration

cycle possible are: heat always flows from a warmer to a

cooler body, under lower pressure a refrigerant will absorb

heat and vaporize at a low temperature, the vapors may be

drawn off and condensed at a higher pressure and tempera-

ture to be used again.

The indoor evaporator coil functions to cool and dehumidify

the air conditioned spaces through the evaporative process

taking place within the coil tubes.

NOTE: The pressures and temperatures shown in the

refrigerant cycle illustrations on the following pages are for

demonstration purposes only. Actual temperatures and pres-

sures are to be obtained from the "Expanded Performance

Chart."

Liquid refrigerant at condensing pressure and temperatures,

(270 psig and 122°F), leaves the outdoor condensing coil

through the drier and is metered into the indoor coil through

the metering device. As the cool, low pressure, saturated

refrigerant enters the tubes of the indoor coil, a portion of the

liquid immediately vaporizes. It continues to soak up heat and

vaporizes as it proceeds through the coil, cooling the indoor

coil down to about 48°F.

Heat is continually being transferred to the cool fins and tubes

of the indoor evaporator coil by the warm system air. This

warming process causes the refrigerant to boil. The heat

removed from the air is carried off by the vapor.

As the vapor passes through the last tubes of the coil, it

becomes superheated, that is, it absorbs more heat than is

necessary to vaporize it. This is assurance that only dry gas

will reach the compressor. Liquid reaching the compressor

can weaken or break compressor valves.

The compressor increases the pressure of the gas, thus

adding more heat, and discharges hot, high pressure super-

heated gas into the outdoor condenser coil.

In the condenser coil, the hot refrigerant gas, being warmer

than the outdoor air, first loses its superheat by heat trans-

ferred from the gas through the tubes and fins of the coil. The

refrigerant now becomes saturated, part liquid, part vapor and

then continues to give up heat until it condenses to a liquid

alone. Once the vapor is fully liquefied, it continues to give up

heat which subcools the liquid, and it is ready to repeat the

cycle.

HEATING

The heating portion of the refrigeration cycle is similar to the

cooling cycle. By energizing the reversing valve solenoid coil,

the flow of the refrigerant is reversed. The indoor coil now

becomes the condenser coil, and the outdoor coil becomes

the evaporator coil.

The check valve at the indoor coil will open by the flow of

refrigerant letting the now condensed liquid refrigerant by-

pass the indoor expansion device. The check valve at the

outdoor coil will be forced closed by the refrigerant flow,

thereby utilizing the outdoor expansion device.

The restrictor orifice used with the CA*F, CHPF coils and the

AR*F air handler will be forced onto a seat when running in

the cooling cycle, only allowing liquid refrigerant to pass

through the orifice opening. In the heating cycle it will be

forced off the seat allowing liquid to flow around the restrictor.

A check valve is not required in this circuit.

COOLING CYCLE

When the contacts of the room thermostat close making

terminals R to Y & G, the low voltage circuit of the transformer

is completed. Current now flows through the magnetic hold-

ing coils of the compressor contactor (CC) and fan relay

(RFC).

This draws in the normally open contact CC, starting the

compressor and condenser fan motors. At the same time

contacts RFC close starting the indoor fan motor.

When the thermostat is satisfied, it opens its contacts,

breaking the low voltage circuit, causing the compressor

contactor and indoor fan relay to open, shutting down the

system.

If the room thermostat fan selector switch should be set on

the "on" position, then the indoor blower would run continuous

rather than cycling with the compressor.

Heat pumps energize the reversing valve thorough the "O"

circuit in the room thermostat. Therefore the reversing valve

remains energized as long as the thermostat subbase is in

the cooling position. The only exception to this is during

defrost.

DEFROST CYCLE

The defrosting of the outdoor coil is jointly controlled by the

defrost timing board, defrost (30/60) control, and compressor

run time.

HEATING CYCLE

The reversing valve on the heat pump models is energized in

the cooling cycle through the "O" terminal on the room

thermostat.

These models have a 24 volt reversing valve coil. When the

thermostat selector switch is set in the cooling position, the

"O" terminal on the thermostat is energized all the time.

Care must be taken when selecting a room thermostat. Refer

to the installation instructions shipped with the product for

approved thermostats.

SYSTEM OPERATION

AFE18-60A CONTROL BOARD

DESCRIPTION

The AFE18 control is designed for use in heat pump applica-

tions where the indoor coil is located above/downstream of a

gas or fossil fuel furnace. It will operate with single and two

stage heat pumps and single and two stage furnaces. The

AFE18 control will turn the heat pump unit off when the

furnace is turned on. An anti-short cycle feature is also

incorporated which initiates a 3 minute timed off delay when

the compressor goes off. On initial power up or loss and

restoration of power, this 3 minute timed off delay will be

initiated. The compressor won’t be allowed to restart until the

3 minute off delay has expired. Also included is a 5 second

de-bounce feature on the “Y, E, W1 and O” thermostat inputs.

These thermostat inputs must be present for 5 seconds

before the AFE18 control will respond to it.

An optional outdoor thermostat, OT18-60A, can be used with

the AFE18 to switch from heat pump operation to furnace

operation below a specific ambient temperature setting, i.e.

break even temperature during heating. When used in this

manner, the “Y” heat demand is switched to the “W1” input

to the furnace by the outdoor thermostat and the furnace is

used to satisfy the first stage “Y” heat demand. On some

controls, if the outdoor thermostat fails closed in this position

during the heating season, it will turn on the furnace during

the cooling season on a “Y” cooling demand. In this

situation, the furnace produces heat and increases the

indoor temperature thereby never satisfying the cooling

demand. The furnace will continue to operate and can only

be stopped by switching the thermostat to the off position or

removing power to the unit and then replacing the outdoor

thermostat. When the AFE18 receives a “Y” and “O”

input from the indoor thermostat, it recognizes this as a

cooling demand in the cooling mode. If the outdoor thermo-

stat is stuck in the closed position switching the “Y” demand

to the “W1” furnace input during the cooling mode as

described above, the AFE18 won’t allow the furnace to

operate. The outdoor thermostat will have to be replaced to

restore the unit to normal operation.

S-1 CHECKING VOLTAGE

1. Remove outer case, control panel cover, etc., from unit

being tested.

With power ON:

WARNING

Line Voltage now present.

2. Using a voltmeter, measure the voltage across terminals

L1 and L2 of the contactor for the condensing unit or at the

field connections for the air handler or heaters.

3. No reading - indicates open wiring, open fuse(s) no power

or etc., from unit to fused disconnect service. Repair as

needed.

4. With ample voltage at line voltage connectors, energize

the unit.

5. Measure the voltage with the unit starting and operating,

and determine the unit Locked Rotor Voltage. NOTE: If

checking heaters, be sure all heating elements are

energized.

Locked Rotor Voltage is the actual voltage available at

the compressor during starting, locked rotor, or a stalled

condition. Measured voltage should be above minimum

listed in chart below.

To measure Locked Rotor Voltage attach a voltmeter to

the run "R" and common "C" terminals of the compressor,

or to the T1 and T2 terminals of the contactor. Start the unit

and allow the compressor to run for several seconds, then

shut down the unit. Immediately attempt to restart the

unit while measuring the Locked Rotor Voltage.

6. Lock rotor voltage should read within the voltage tabula-

tion as shown. If the voltage falls below the minimum

voltage, check the line wire size. Long runs of undersized

wire can cause low voltage. If wire size is adequate, notify

the local power company in regard to either low or high

voltage.

or replace as necessary.

Resistance Heaters

1. Set room thermostat to a higher setting than room

temperature so both stages call for heat.

2. With voltmeter, check for 24 volts at each heater relay.

Note: BBA/BBC heater relays are DC voltage.

3. No voltage indicates the trouble is in the thermostat or

wiring.

4. Check the continuity of the thermostat and wiring. Repair

or replace as necessary.

NOTE: Consideration must be given to how the heaters are

wired (O.D.T. and etc.). Also safety devices must be checked

for continuity.

S-3B COOLING ANTICIPATOR

The cooling anticipator is a small heater (resistor) in the

thermostat. During the "off" cycle, it heats the bimetal

element helping the thermostat call for the next cooling cycle.

This prevents the room temperature from rising too high

before the system is restarted. A properly sized anticipator

should maintain room temperature within 1 1/2 to 2 degree

range.

The anticipator is supplied in the thermostat and is not to be

replaced. If the anticipator should fail for any reason, the

thermostat must be changed.

S-3C HEATING ANTICIPATOR

The heating anticipator is a wire wound adjustable heater

which is energized during the "ON" cycle to help prevent

overheating of the conditioned space.

The anticipator is a part of the thermostat and if it should fail

for any reason, the thermostat must be replaced. See the

following tables for recommended heater anticipator setting

in accordance to the number of electric heaters installed.

2. Using a voltmeter, check voltage across secondary volt-

age side of transformer (R to C).

3. No voltage indicates faulty transformer, bad wiring, or bad

splices.

4. Check transformer primary voltage at incoming line volt-

age connections and/or splices.

5 If line voltage available at primary voltage side of trans-

former and wiring and splices good, transformer is inop-

erative. Replace.

S-5 CHECKING CYCLE PROTECTOR

Some models feature a solid state, delay-on make after break

time delay relay installed in the low voltage circuit. This

control is used to prevent short cycling of the compressor

under certain operating conditions.

The component is normally closed (R1 to Y1). A power

interruption will break circuit (R1

to Y1) for approximately three

minutes before resetting.

1. Remove wire from Y1 terminal.

3. Remove 24 VAC at terminals R1 and R2.

4. Should read 0 VAC at Y1 and Y2.

5. Reapply 24 VAC to R1 and R2 - within approximately

three (3) to four (4) minutes should read 24 VAC at Y1 and

Y2.

If not as above - replace relay.

S-6 CHECKING TIME DELAY RELAY

Time delay relays are used in some of the blower cabinets to

improve efficiency by delaying the blower off time. Time

delays are also used in electric heaters to sequence in

multiple electric heaters.

WARNING

S-11 CHECKING LOSS OF CHARGE PROTECTOR

(Heat Pump Models)

The loss of charge protector senses the pressure in the liquid

line and will open its contacts on a drop in pressure. The low

pressure control will automatically reset itself with a rise in

pressure.

The low pressure control is designed to cut-out (open) at

approximately 7 PSIG. It will automatically cut-in (close) at

approximately 25 PSIG.

Test for continuity using a VOM and if not as above, replace

the control.

S-15 CHECKING CAPACITOR

CAPACITOR, RUN

A run capacitor is wired across the auxiliary and main

windings of a single phase permanent split capacitor motor.

The capacitors primary function is to reduce the line current

while greatly improving the torque characteristics of a motor.

This is accomplished by using the 90° phase relationship

between the capacitor current and voltage in conjunction with

the motor windings, so that the motor will give two phase

operation when connected to a single phase circuit. The

capacitor also reduces the line current to the motor by

improving the power factor.

The line side of this capacitor is marked with "COM" and is

wired to the line side of the circuit.

CAPACITOR, START

SCROLL COMPRESSOR MODELS

In most cases hard start components are not required on

Scroll compressor equipped units due to a non-replaceable

check valve located in the discharge line of the compressor.

However, in installations that encounter low lock rotor volt-

age, a hard start kit can improve starting characteristics and

reduce light dimming within the home. Only hard start kits

approved by Amana® brand or Copeland should be used.

"Kick Start" and/or "Super Boost" kits are not approved start

assist devices.

The discharge check valve closes off high side pressure to the

compressor after shut down allowing equalization through the

scroll flanks. Equalization requires only about ½ second.

To prevent the compressor from short cycling, a Time Delay

Relay (Cycle Protector) has been added to the low voltage

circuit.

RELAY, START

A potential or voltage type relay is used to take the start

capacitor out of the circuit once the motor comes up to speed.

This type of relay is position sensitive. The normally closed

contacts are wired in series with the start capacitor and the

relay holding coil is wired parallel with the start winding. As

the motor starts and comes up to speed, the increase in

voltage across the start winding will energize the start relay

holding coil and open the contacts to the start capacitor.

Two quick ways to test a capacitor are a resistance and a

capacitance check.

S-16A CHECKING FAN AND BLOWER MOTOR

WINDINGS (PSC MOTORS)

The auto reset fan motor overload is designed to protect the

motor against high temperature and high amperage condi-

tions by breaking the common circuit within the motor, similar

to the compressor internal overload. However, heat gener-

ated within the motor is faster to dissipate than the compres-

sor, allow at least 45 minutes for the overload to reset, then

retest.

1. Remove the motor leads from its respective connection

points and capacitor (if applicable).

2. Check the continuity between each of the motor leads.

3. Touch one probe of the ohmmeter to the motor frame

(ground) and the other probe in turn to each lead.

If the windings do not test continuous or a reading is obtained

from lead to ground, replace the motor.

S-16B CHECKING FAN AND BLOWER MOTOR

(ECM MOTORS)

An ECM is an Electronically Commutated Motor which offers

many significant advantages over PSC motors. The ECM

has near zero rotor loss, synchronous machine operation,

variable speed, low noise, and programmable air flow. Be-

cause of the sophisticated electronics within the ECM

motor, some technicians are intimated by the ECM motor;

however, these fears are unfounded. GE offers two ECM

motor testers, and with a VOM meter, one can easily perform

basic troubleshooting on ECM motors. An ECM motor

requires power (line voltage) and a signal (24 volts) to

operate. The ECM motor stator contains permanent magnet.

As a result, the shaft feels "rough" when turned by hand. This

is a characteristic of the motor, not an indication of defective

bearings.

WARNING

Line Voltage now present.

1. Disconnect the 5-pin connector from the motor.

2. Using a volt meter, check for line voltage at terminals #4

& #5 at the power connector. If no voltage is present:

3. Check the unit for incoming power See section S-1.

4. Check the control board, See section S-40.

5. If line voltage is present, reinsert the 5-pin connector and

remove the 16-pin connector.

6. Check for signal (24 volts) at the transformer.

7. Check for signal (24 volts) from the thermostat to the "G"

terminal at the 16-pin connector.

8. Using an ohmmeter, check for continuity from the #1 &

#3 (common pins) to the transformer neutral or "C"

thermostat terminal. If you do not have continuity, the

motor may function erratically. Trace the common cir-

cuits, locate and repair the open neutral.

9. Set the thermostat to "Fan-On". Using a voltmeter,

check for 24 volts between pin # 15 (G) and common.

10. Disconnect power to compressor. Set thermostat to call

for cooling. Using a voltmeter, check for 24 volts at pin #

6 and/or #14.

11. Set the thermostat to a call for heating. Using a voltme-

ter, check for 24 volts at pin #2 and/or #11.

set with the dipswitch #4 in the “ON” position and all other

dipswitches are factory set in the “OFF” position. When

MBE is used with 2-stage cooling units, dipswitch #4

should be in the "OFF" position.

For most applications, the settings are to be changed

according to the electric heat size and the outdoor unit

selection.

The MBE product uses a General Electric ECMTM motor.

This motor provides many features not available on the

traditional PSC motor. These features include:

• Improved Efficiency

• Constant CFM

• Soft Start and Stop

• Improved Humidity Control

MOTOR SPEED ADJUSTMENT

Each ECM™ blower motor has been preprogrammed for

operation at 4 distinct airflow levels when operating in

Cooling/Heat Pump mode or Electric Heat mode. These 4

distinct levels may also be adjusted slightly lower or higher

if desired. The adjustment between levels and the trim

adjustments are made by changing the dipswitch(s) either

to an "OFF" or "ON" position.

S-16E CHECKING GE X13TM MOTORS

The GE X13TM Motor is a one piece, fully encapsulated, 3

phase brushless DC (single phase AC input) motor with ball

bearing construction. Unlike the ECM 2.3/2.5 motors, the GE

X13TM features an integral control module.

Note: The GE TECMate will not currently operate the GE

X13TM motor.

1. Using a voltmeter, check for 230 volts to the motor

connections L and N. If 230 volts is present, proceed to

step 2. If 230 volts is not present, check the line voltage

circuit to the motor.

2. Using a voltmeter, check for 24 volts from terminal C to

either terminal 1, 2, 3, 4, or 5, depending on which tap is

being used, at the motor. If voltage present, proceed to

step 3. If no voltage, check 24 volt circuit to motor.

3. If voltage was present in steps 1 and 2, the motor has

failed and will need to be replaced.

Note: When replacing motor, ensure the belly band is

between the vents on the motor and the wiring has the

proper drip loop to prevent condensate from entering the

motor.

S-17 CHECKING COMPRESSOR

WARNING

Hermetic compressor electrical terminal venting can

be dangerous. When insulating material which

supports a hermetic compressor or electrical terminal

suddenly disintegrates due to physical abuse or as a

result of an electrical short between the terminal and

the compressor housing, the terminal may be

expelled, venting the vapor and liquid contents of the

compressor housing and system.

If the compressor terminal PROTECTIVE COVER and gasket

(if required) are not properly in place and secured, there is a

remote possibility if a terminal vents, that the vaporous and

liquid discharge can be ignited, spouting flames several feet,

causing potentially severe or fatal injury to anyone in its path.

This discharge can be ignited external to the compressor if

the terminal cover is not properly in place and if the discharge

impinges on a sufficient heat source.

Ignition of the discharge can also occur at the venting terminal

or inside the compressor, if there is sufficient contaminant air

present in the system and an electrical arc occurs as the

terminal vents.

Ignition cannot occur at the venting terminal without the

presence of contaminant air, and cannot occur externally

from the venting terminal without the presence of an external

ignition source.

Therefore, proper evacuation of a hermetic system is essen-

tial at the time of manufacture and during servicing.

To reduce the possibility of external ignition, all open flame,

electrical power, and other heat sources should be extin-

guished or turned off prior to servicing a system.

If the following test indicates shorted, grounded or open

windings, see procedures S-19 for the next steps to be taken.

S-17A RESISTANCE TEST

Each compressor is equipped with an internal overload.

The line break internal overload senses both motor amperage

and winding temperature. High motor temperature or amper-

age heats the disc causing it to open, breaking the common

circuit within the compressor on single phase units.

Heat generated within the compressor shell, usually due to

recycling of the motor, high amperage or insufficient gas to

cool the motor, is slow to dissipate. Allow at least three to

four hours for it to cool and reset, then retest.

Fuse, circuit breaker, ground fault protective device, etc. has

not tripped -

SERVICING

1. Remove the leads from the compressor terminals.

See warnings S-17 before removing compressor

terminal cover.

2. Using an ohmmeter, test continuity between terminals S-

R, C-R, and C-S, on single phase units or terminals T2,

T2 and T3, on 3 phase units.

COMP

OHMMETER

TESTING COMPRESSOR WINDINGS

If either winding does not test continuous, replace the

compressor.

NOTE: If an open compressor is indicated, allow ample time

for the internal overload to reset before replacing compressor.

S-17B GROUND TEST

If fuse, circuit breaker, ground fault protective device, etc.,

has tripped, this is a strong indication that an electrical

problem exists and must be found and corrected. The circuit

protective device rating must be checked, and its maximum

rating should coincide with that marked on the equipment

nameplate.

With the terminal protective cover in place, it is acceptable to

replace the fuse or reset the circuit breaker ONE TIME ONLY

to see if it was just a nuisance opening. If it opens again, DO

NOT continue to reset.

Disconnect all power to unit, making sure that all power

legs are open.

1. DO NOT remove protective terminal cover. Disconnect

the three leads going to the compressor terminals at the

nearest point to the compressor.

2. Identify the leads and using a Megger, Hi-Potential

Ground Tester, or other suitable instrument which puts

out a voltage between 300 and 1500 volts, check for a

ground separately between each of the three leads and

ground (such as an unpainted tube on the compressor).

Do not use a low voltage output instrument such as a volt-

ohmmeter.

HI-POT

COMPRESSOR GROUND TEST

3. If a ground is indicated, then carefully remove the com-

pressor terminal protective cover and inspect for loose

leads or insulation breaks in the lead wires.

4. If no visual problems indicated, carefully remove the leads

at the compressor terminals.

WARNING

Damage can occur to the glass embedded terminals if

the leads are not properly removed. This can result in

terminal and hot oil discharging.

Carefully retest for ground, directly between compressor

terminals and ground.

5. If ground is indicated, replace the compressor.

S-17D OPERATION TEST

If the voltage, capacitor, overload and motor winding test fail

to show the cause for failure:

1. Remove unit wiring from disconnect switch and wire a test

cord to the disconnect switch.

NOTE: The wire size of the test cord must equal the line wire

size and the fuse must be of the proper size and type.

2. With the protective terminal cover in place, use the three

leads to the compressor terminals that were discon-

nected at the nearest point to the compressor and

connect the common, start and run clips to the respective

leads.

3. Connect good capacitors of the right MFD and voltage

rating into the circuit as shown.

4. With power ON, close the switch.

WARNING

Line Voltage now present.

SERVICING

A. If the compressor starts and continues to run, the cause

for failure is somewhere else in the system.

B. If the compressor fails to start - replace.

S-18 TESTING CRANKCASE HEATER

(OPTIONAL ITEM)

The crankcase heater must be energized a minimum of four

(4) hours before the condensing unit is operated.

Crankcase heaters are used to prevent migration or accumu-

lation of refrigerant in the compressor crankcase during the

off cycles and prevents liquid slugging or oil pumping on start

up.

A crankcase heater will not prevent compressor damage due

to a floodback or over charge condition.

WARNING

Disconnect ALL power before servicing.

1. Disconnect the heater lead in wires.

2. Using an ohmmeter, check heater continuity - should test

continuous. If not, replace.

NOTE: The positive temperature coefficient crankcase heater

is a 40 watt 265 voltage heater. The cool resistance of the

heater will be approximately 1800 ohms. The resistance will

become greater as the temperature of the compressor shell

increases.

S-21 CHECKING REVERSING VALVE

AND SOLENOID

Occasionally the reversing valve may stick in the heating or

cooling position or in the mid-position.

When stuck in the mid-position, part of the discharge gas

from the compressor is directed back to the suction side,

resulting in excessively high suction pressure. An increase

in the suction line temperature through the reversing valve can

also be measured. Check operation of the valve by starting

the system and switching the operation from COOLING to

HEATING cycle.

If the valve fails to change its position, test the voltage (24V)

at the valve coil terminals, while the system is on the

COOLING cycle.

If no voltage is registered at the coil terminals, check the

operation of the thermostat an the continuity of the connect-

ing wiring from the "O" terminal of the thermostat to the unit.

If voltage is registered at the coil, tap the valve body lightly

while switching the system from HEATING to COOLING, etc.

If this fails to cause the valve to switch positions, remove the

coil connector cap and test the continuity of the reversing

valve solenoid coil. If the coil does not test continuous -

replace it.

If the coil test continuous and 24 volts is present at the coil

terminals, the valve is inoperative - replace it.

S-24 TESTING DEFROST CONTROL

To check the defrost control for proper sequencing, proceed

as follows: With power ON; unit not running.

1. Jumper defrost thermostat by placing a jumper wire

across the terminals "DFT" and "R" at defrost control

board.

2. Connect jumper across test pins on defrost control board.

3. Set thermostat to call for heating. System should go into

defrost within 21 seconds.

4. Immediately remove jumper from test pins.

5. Using VOM check for voltage across terminals "C & O".

Meter should read 24 volts.

6. Using VOM check for voltage across fan terminals DF1

and DF2 on the board. You should read line voltage (208-

230 VAC) indicating the relay is open in the defrost mode.

7. Using VOM check for voltage across "W2 & C" terminals

on the board. You should read 24 volts.

8. If not as above, replace control board.

9. Set thermostat to off position and disconnect power

before removing any jumpers or wires.

NOTE: Remove jumper across defrost thermostat before

returning system to service.

S-25 TESTING DEFROST THERMOSTAT

1. Install a thermocouple type temperature test lead on the

tube adjacent to the defrost control. Insulate the lead

point of contact.

2. Check the temperature at which the control closes its

contacts by lowering the temperature of the control. Part

# 0130M00009P which is used on 2 and 2.5 ton units

should close at 34°F ± 5°F. Part # 0130M00001P which

is used on 3 thru 5 ton units should close at 31°F ± 3°F.

3. Check the temperature at which the control opens its

contacts by raising the temperature of the control. Part #

0130M00009P which is used on 2 and 2.5 ton units

should open at 60°F ± 5°F. Part # 0130M00001P which

is used on 3 thru 5 ton units should open at 75°F ± 6°F.

4. If not as above, replace control.

SERVICING

S-40 AR*F & MBR ELECTRONIC BLOWERS

TIME DELAY RELAY

The MBR contains an Electronic Blower Time Delay Relay

board, B1370735. This board provides on/off time delays for

the blower motor in cooling and heat pump heating demands

when “G” is energized.

During a cooling or heat pump heating demand, 24Vac is

supplied to terminal “G” of the EBTDR to turn on the blower

motor. The EBTDR initiates a 7 second delay on and then

energizes it’s onboard relay. The relay on the EBTDR board

closes it’s normally open contacts and supplies power to the

blower motor. When the “G” input is removed, the EBTDR

initiates a 65 second delay off. When the 65 seconds delay

expires the onboard relay is de-energized and it’s contacts

open and remove power from the blower motor.

During an electric heat only demand, “W1” is energized but

“G” is not. The blower motor is connected to the normally

closed contacts of the relay on the EBTDR board. The other

side of this set of contacts is connected to the heat se-

quencer on the heater assembly that provides power to the

first heater element. When “W1” is energized, the sequencer

will close it’s contacts within 10 to 20 seconds to supply

power to the first heater element and to the blower motor

through the normally closed contacts on the relay on the

EBTDR. When the “W1” demand is removed, the sequencer

opens it contacts within 30 to 70 seconds and removes power

from the heater element and the blower motor.

The EBTDR also contains a speedup terminal to reduce the

delays during troubleshooting of the unit. When this terminal

is shorted to the common terminal, “C”, on the EBTDR board,

the delay ON time is reduced to 3 seconds and the delay OFF

time is reduced to 5 second.

Two additional terminals, M1 and M2, are on the EBTDR

board. These terminals are used to connect the unused leads

from the blower motor and have no affect on the board’s

operation.

SEQUENCE OF OPERATION

This document covers the basic sequence of operation for a

typical application with a mercury bulb thermostat. When a

digital/electronic thermostat is used, the on/off staging of the

auxiliary heat will vary. Refer to the installation instruc-

tions and wiring diagrams provided with the MBR and

AR*F for specific wiring connections and system con-

figuration.

AR*F & MBR

WITH SINGLE STAGE CONDENSERS

1.0 Cooling Operation

1.1 On a demand for cooling, the room thermostat energizes

“G” and “Y” and 24Vac is supplied to “Y” at the condensing

unit and the “G” terminal on the EBTDR board.

1.2 The compressor and condenser fan are turned on and

after a 7 second on delay, the relay on the EBTDR board

is energized and the blower motor starts.

1.3 When the cooling demand “Y” is satisfied, the room

thermostat removes the 24Vac from “G” and “Y”.

1.4 The compressor and condenser fan are turned off and after

a 65 second delay off, the relay on the EBTDR board is de-

energized and the blower is turned off.

2.0 Heating Operation

2.1 On a demand for heat, the room thermostat energizes

“W1” and 24Vac is supplied to heat sequencer, HR1, on

the heater assembly.

2.2 The contacts M1 and M2 will close within 10 to 20

seconds and turn on heater element #1. The normally

closed contacts on the EBTDR are also connected to

terminal M1. When M1 and M2 close, the blower motor

will be energized thru the normally closed contacts on the

EBTDR board. At the same time, if the heater assembly

contains a second heater element, HR1 will contain a

second set of contacts, M3 and M4, which will close to

turn on heater element #2.

Note: If more than two heater elements are on the heater

assembly, it will contain a second heat sequencer, HR2,

which will control the 3rd and 4th heater elements if available.

If the first stage heat demand, “W1” cannot be satisfied by the

heat pump, the temperature indoors will continue to drop. The

room thermostat will then energize “W2” and 24Vac will be

supplied to HR2 on the heater assembly. When the “W2”

demand is satisfied, the room thermostat will remove the

24Vac from HR2. The contacts on HR2 will open between 30

to 70 seconds and heater elements #3 and #4 will be turned

off. On most digital/electronic thermostats, “W2” will

remain energized until the first stage demand “W1” is

satisfied and then the “W1” and “W2” demands will be

removed.

2.3 When the “W1” heat demand is satisfied, the room

thermostat will remove the 24Vac from HR1. Both set of

contacts on the relay opens within 30 to 70 seconds and

turn off the heater element(s) and the blower motor.

AR*F & MBR

WITH SINGLE STAGE HEAT PUMPS

3.0 Cooling Operation

On heat pump units, when the room thermostat set to the

cooling mode, 24Vac is supplied to “O” which energizes the

reversing valve. As long as the thermostat is set for cooling,

the reversing valve will be in the energized position for cooling.

3.1 On a demand for cooling, the room thermostat energizes

“G” and “Y” and 24Vac is supplied to “Y” at the heat pump

and the “G” terminal on the EBTDR board.

3.2 The heat pump turned on in the cooling mode and after a

7 second on delay, the relay on the EBTDR board is

energized and the blower motor starts.

3.3 When the cooling demand is satisfied, the room thermo-

stat removes the 24Vac from “G” and “Y”.

3.4 The heat pump is turned off and after a 65 second delay

off, the relay on the EBTDR board is de-energized and the

blower motor is turned off.

SERVICING

4.0 Heating Operation

On heat pump units, when the room thermostat set to the

heating mode, the reversing valve is not energized. As long

as the thermostat is set for heating, the reversing valve will be

in the de-energized position for heating except during a

defrost cycle. Some installations may use one or more

outdoor thermostats to restrict the amount of electric heat

that is available above a preset ambient temperature. Use of

optional controls such as these can change the operation of

the electric heaters during the heating mode. This sequence

of operation does not cover those applications.

4.1 On a demand for first stage heat with heat pump units, the

room thermostat energizes “G” and “Y” and 24Vac is

supplied to “Y” at the heat pump unit and the “G” terminal

on the EBTDR board. The heat pump is turned on in the

heating mode and the blower motor starts after a 7 second

on delay.

4.2 If the first stage heat demand cannot be satisfied by the

heat pump, the temperature indoors will continue to drop.

The room thermostat will then energize terminal “W2’ for

second stage heat and 24Vac will be supplied to heat

sequencer HR1 on the heater assembly.

4.3 HR1 contacts M1 and M2 will close will close within 10

to 20 seconds and turn on heater element #1. At the

same time, if the heater assembly contains a second

heater element, HR1 will contain a second set of con-

tacts, M3 and M4, which will close and turn on heater

element #2. The blower motor is already on as a result

of terminal “G” on the EBTDR board being energized for

the first stage heat demand.

Note: If more than two heater elements are on the heater

assembly, it will contain a second heat sequencer, HR2,

which will control the 3rd and 4th heater elements if available.

If the second stage heat demand, “W2” cannot be satisfied by

the heat pump, the temperature indoors will continue to drop.

The room thermostat will then energize “W3” and 24Vac will

be supplied to HR2 on the heater assembly. When the “W3”

demand is satisfied, the room thermostat will remove the

24Vac from HR2. The contacts on HR2 will open between 30

to 70 seconds and heater elements #3 and #4 will be turned

off. On most digital/electronic thermostats, “W3” will

remain energized until the first stage heat demand “Y”

is satisfied and then the “G”, “Y”, “W2” and “W3”

demands will be removed.

4.4 As the temperature indoors increase, it will reach a point

where the second stage heat demand, “W2”, is satisfied.

When this happens, the room thermostat will remove the

24Vac from the coil of HR1. The contacts on HR1 will

open between 30 to 70 seconds and turn off both heater

element(s). The heat pump remains on along with the

blower motor because the “Y” demand for first stage heat

will still be present.

4.5 When the first stage heat demand “Y” is satisfied, the

room thermostat will remove the 24Vac from “G” and “Y”.

The heat pump is turned off and the blower motor turns off

after a 65 second off delay.

5.0 Defrost Operation

On heat pump units, when the room thermostat is set to the

heating mode, the reversing valve is not energized. As long

as the thermostat is set for heating, the reversing valve will be

in the de-energized position for heating except during a

defrost cycle.

5.1 The heat pump will be on and operating in the heating

mode as described the Heating Operation in section 4.

5.2 The defrost control in the heat pump unit checks to see

if a defrost is needed every 30, 60 or 90 minutes of heat

pump operation depending on the selectable setting by

monitoring the state of the defrost thermostat attached to

the outdoor coil.

5.3 If the temperature of the outdoor coil is low enough to

cause the defrost thermostat to be closed when the

defrost board checks it, the board will initiate a defrost

cycle.

5.4 When a defrost cycle is initiated, the contacts of the

HVDR relay on the defrost board open and turns off the

outdoor fan. The contacts of the LVDR relay on the

defrost board closes and supplies 24Vac to “O” and “W2”.

The reversing valve is energized and the contacts on HR1

close and turns on the electric heater(s). The unit will

continue to run in this mode until the defrost cycle is

completed.

5.5 When the temperature of the outdoor coil rises high

enough to causes the defrost thermostat to open, the

defrost cycle will be terminated. If at the end of the

programmed 10 minute override time the defrost thermo-

stat is still closed, the defrost board will automatically

terminate the defrost cycle.

5.6 When the defrost cycle is terminated, the contacts of the

HVDR relay will close to start the outdoor fan and the

contacts of the LVDR relay will open and turn off the

reversing valve and electric heater(s). The unit will now be

back in a normal heating mode with a heat pump demand

for heating as described in the Heating Operation in

section 4.

S-41 AEP* & MBE WITH SINGLE STAGE CON-

DENSERS

AEP* & MBE ELECTRONIC BLOWER TIME DELAY RELAY

SEQUENCE OF OPERATION

This document covers the basic sequence of operation for a

typical application with a mercury bulb thermostat. When a

digital/electronic thermostat is used, the on/off staging of the

auxiliary heat will vary. Refer to the installation instructions

and wiring diagrams provided with the MBE for specific wiring

connections, dip switch settings and system configuration.

SERVICING

AEP* & MBE WITH SINGLE STAGE CONDENSERS

When used with a single stage condenser, dip switch #4

must be set to the on position on the VSTB inside the MBE.

The “Y” output from the indoor thermostat must be connected

to the yellow wire labeled “Y/Y2” inside the wire bundle

marked “Thermostat” and the yellow wire labeled “Y/Y2”

inside the wire bundle marked “Outdoor Unit” must be

connected to “Y” at the condenser. The orange jumper wire

from terminal “Y1” to terminal “O” on the VSTB inside the

MBE must remain connected.

1.0 Cooling Operation

1.1 On a demand for cooling, the room thermostat energizes

“G” and “Y” and 24Vac is supplied to “G” and “Y/Y2” of the

MBE unit. The VSTB inside the MBE will turn on the

blower motor and the motor will ramp up to the speed

programmed in the motor based on the settings for dip

switch 5 and 6. The VSTB will supply 24Vac to “Y” at the

condenser and the compressor and condenser are turned

on.

1.2 When the cooling demand is satisfied, the room thermo-

stat removes the 24Vac from “G” and “Y”. The MBEand

AEP* remove the 24Vac from “Y’ at the condenser and the

compressor and condenser fan are turned off. The blower

motor will ramp down to a complete stop based on the

time and rate programmed in the motor.

2.0 Heating Operation

2.1 On a demand for heat, the room thermostat energizes

“W1” and 24Vac is supplied to terminal “E/W1” of the

VSTB inside the MBEand AEP* units. The VSTB will turn

on the blower motor and the motor will ramp up to the

speed programmed in the motor based on the settings for

dip switch 1 and 2. The VSTB will supply 24Vac to heat

sequencer HR1 on the electric heater assembly.

2.2 HR1 contacts M1 and M2 will close within 10 to 20

seconds and turn on heater element #1. At the same

time, if the heater assembly contains a second heater

element, HR1 will contain a second set of contacts, M3

and M4, which will close and turn on heater element #2.

Note: If more than two heater elements are on the heater

assembly, it will contain a second heat sequencer, HR2,

which will control the 3rd and 4th heater elements if

available. For the 3rd and 4th heater elements to

operate on a second stage heat demand, the PJ4

jumper on the VSTB inside the MBE and AEP* must

be cut. With the PJ4 jumper cut, the VSTB will run the

blower motor on low speed on a “W1” only demand. If the

first stage heat demand, “W1” cannot be satisfied by the

heat pump, the temperature indoors will continue to drop.

The room thermostat will then energize “W2” and 24Vac

will be supplied to HR2 on the heater assembly and the

blower motor will change to high speed. When the “W2”

demand is satisfied, the room thermostat will remove the

24Vac from “W2” and the VSTB will remove the 24Vac

from HR2. The contacts on HR2 will open between 30 to

70 seconds and heater elements #3 and #4 will be turned

off and the blower motor will change to low speed. On

most digital/electronic thermostats, “W2” will re-

main energized until the first stage demand “W1” is

satisfied and then the “W1” and “W2” demands will

be removed.

2.3 When the “W1” heat demand is satisfied, the room

thermostat will remove the 24Vac from “E/W1” and the

VSTB removes the 24Vac from HR1. The contacts on

HR1 will open between 30 to 70 seconds and turn off the

heater element(s) and the blower motor ramps down to a

complete stop.

S-41A AEP* & MBE WITH SINGLE STAGE HEAT

PUMPS

When used with a single stage heat pump, dip switch #4 must

be set to the ON position on the VSTB inside the MBE. The

“Y” output from the indoor thermostat must be connected to

the yellow wire labeled “Y/Y2” inside the wire bundle marked

“Thermostat” and the yellow wire labeled “Y/Y2” inside the

wire bundle marked “Outdoor Unit” must be connected to “Y”

at the heat pump. The orange jumper wire from terminal

“Y1” to terminal “O” on the VSTB inside the MBE must

be removed.

3.0 Cooling Operation

On heat pump units, when the room thermostat is set to the

cooling mode, 24Vac is supplied to terminal “O” of the VSTB

inside the MBE unit. The VSTB will supply 24Vac to “O” at

the heat pump to energize the reversing valve. As long as the

thermostat is set for cooling, the reversing valve will be in the

energized position for cooling.

3.1 On a demand for cooling, the room thermostat energizes

“G” and “Y” and 24Vac is supplied to terminals “G” and “Y/

Y2” of the MBE unit. The VSTB will turn on the blower

motor and the motor will ramp up to the speed pro-

grammed in the motor based on the settings of dip switch

5 and 6. The VSTB will supply 24Vac to “Y” at the heat

pump.

3.2 The heat pump is turned on in the cooling mode.

3.3 When the cooling demand is satisfied, the room thermo-

stat removes the 24Vac from “G” and “Y/Y2” of the MBE

and the VSTB removes the 24Vac from “Y” at the heat

pump. The heat pump is turned off and the blower motor

will ramp down to a complete stop based on the time and

SERVICING

rate programmed in the motor.

4.0 Heating Operation

On heat pump units, when the room thermostat is set to the

heating mode, the reversing valve is not energized. As long

as the thermostat is set for heating, the reversing valve will be

in the de-energized position for heating except during a

defrost cycle. Some installations may use one or more

outdoor thermostats to restrict the amount of electric heat

that is available above a preset ambient temperature. Use of

optional controls such as these can change the operation of

the electric heaters during the heating mode. This sequence

of operation does not cover those applications.

4.1 On a demand for first stage heat with heat pump units, the

room thermostat energizes “Y” and “G” and 24Vac is

supplied to “G” and “Y/Y2” of the MBE. The VSTB will turn

on the blower motor and the motor will ramp up to the

speed programmed in the motor based on the settings of

dip switch 1 and 2. The VSTB will supply 24Vac to “Y” at

the heat pump and the heat pump is turned on in the

heating mode.

4.2 If the first stage heat demand cannot be satisfied by the

heat pump, the temperature indoors will continue to drop.

The room thermostat will then energize terminal “W2” for

second stage heat and 24Vac will be supplied to “E/W1”

of the MBE. The VSTB will supply 24Vac to heat

sequencer, HR1, on the electric heater assembly.

4.3 HR1 contacts M1 and M2 will close within 10 to 20

seconds and turn on heater element #1. At the same

time, if the heater assembly contains a second heater

element, HR1 will contain a second set of contacts, M3

and M4, which will close to turn on heater element #2.

Note: If more than two heater elements are on the heater

assembly, it will contain a second heat sequencer, HR2,

which will control the 3rd and 4th heater elements if available.

For the 3rd and 4th heater elements to operate on a third

stage heat demand, the PJ4 jumper on the VSTB inside

the MBE and AEP* must be cut. If the second stage heat

demand, “W2”, cannot be satisfied by the heat pump, the

temperature indoors will continue to drop. The room thermo-

stat will then energize “W3” and 24Vac will be supplied to “W/

W2” of the MBE. The VSTB will supply 24Vac to HR2 on the

electric heater assembly. When the “W3” demand is satis-

fied, the room thermostat will remove the 24Vac from “W/W2”

of the MBE and AEP*. The contacts on HR2 will open

between 30 to 70 seconds and heater elements #3 and #4 will

be turned off. On most digital/electronic thermostats,

“W3” will remain energized until the first stage de-

mand “Y” is satisfied and then the “G”, “Y”, “W2” and

“W3” demands will be removed.

4.4 As the temperature indoors increase, it will reach a point

where the second stage heat demand, “W2”, is satisfied.

When this happens, the room thermostat will remove the

24Vac from “E/W1” of the MBE. The contacts on HR1 will

open between 30 to 70 seconds and turn off both heater

element(s). The heat pump remains on along with the

blower motor because the “Y” demand for first stage heat

will still be present.

4.5 When the first stage heat demand “Y” is satisfied, the

room thermostat will remove the 24Vac from “G” and “Y/

Y2” of the MBE and AEP*. The VSTB removes the 24Vac

from “Y” at the heat pump and the heat pump is turned off.

The blower motor will ramp down to a complete stop

based on the time and rate programmed in the motor

control.

5.0 Defrost Operation

On heat pump units, when the room thermostat is set to the

heating mode, the reversing valve is not energized. As long

as the thermostat is set for heating, the reversing valve will be

in the de-energized position for heating except during a

defrost cycle.

5.1 The heat pump will be on and operating in the heating

mode as described the Heating Operation in section 4.

5.2 The defrost control in the heat pump unit checks to see

if a defrost is needed every 30, 60 or 90 minutes of heat

pump operation depending on the selectable setting by

monitoring the state of the defrost thermostat attached to

the outdoor coil.

5.3 If the temperature of the outdoor coil is low enough to

cause the defrost thermostat to be closed when the

defrost board checks it, the board will initiate a defrost

cycle.

5.4 When a defrost cycle is initiated, the contacts of the

HVDR relay on the defrost board open and turns off the

outdoor fan. The contacts of the LVDR relay on the

defrost board closes and supplies 24Vac to “O” and “W2”.

The reversing valve is energized and the contacts on HR1

close and turns on the electric heater(s). The unit will

continue to run in this mode until the defrost cycle is

completed.

5.5 When the temperature of the outdoor coil rises high

enough to causes the defrost thermostat to open, the

defrost cycle will be terminated. If at the end of the

programmed 10 minute override time the defrost thermo-

stat is still closed, the defrost board will automatically

terminate the defrost cycle.

5.6 When the defrost cycle is terminated, the contacts of the

HVDR relay on the defrost board will close to start the

outdoor fan and the contacts of the LVDR relay will open

and turn off the reversing valve and electric heater(s). The

unit will now be back in a normal heating mode with a heat

pump demand for heating as described in the Heating

Operation in section 4.

S-60 ELECTRIC HEATER (OPTIONAL ITEM)

Optional electric heaters may be added, in the quantities

shown in the specifications section, to provide electric

resistance heating. Under no condition shall more heaters

than the quantity shown be installed.

The low voltage circuit in the air handler is factory wired and

terminates at the location provided for the electric heater(s).

A minimum of field wiring is required to complete the instal-

SERVICING

lation.

Other components such as a Heating/Cooling Thermostat

and Outdoor Thermostats are available to complete the

installation.

The system CFM can be determined by measuring the static

pressure external to the unit. The installation manual

supplied with the blower coil, or the blower performance table

in the service manual, shows the CFM for the static mea-

sured.

Alternately, the system CFM can be determined by operating

the electric heaters and indoor blower WITHOUT having the

compressor in operation. Measure the temperature rise as

close to the blower inlet and outlet as possible.

If other than a 240V power supply is used, refer to the BTUH

CAPACITY CORRECTION FACTOR chart below.

BTUH CAPACITY CORRECTION FACTOR

SUPPLY VOLTAGE 250 230 220 208

MULTIPLICATION FACTOR 1.08 .92 .84 .75

EXAMPLE: Five (5) heaters provide 24.0 KW at the rated

240V. Our actual measured voltage is 220V, and our

measured temperature rise is 42°F. Find the actual CFM:

Answer: 24.0KW, 42°F Rise, 240 V = 1800 CFM from the

TEMPERATURE RISE CHART, Table 5.

Heating output at 220 V = 24.0KW x 3.413 x .84 = 68.8

MBH.

Actual CFM = 1800 x .84 Corr. Factor = 1400 CFM.

NOTE: The temperature rise table is for sea level installa-

tions. The temperature rise at a particular KW and CFM will

be greater at high altitudes, while the external static pressure

at a particular CFM will be less.

S-61A CHECKING HEATER LIMIT CONTROL(S)

Each individual heater element is protected with a limit

control device connected in series with each element to

prevent overheating of components in case of low airflow. This

limit control will open its circuit at approximately 150°F.

SERVICING

1. Remove the wiring from the control terminals.

2. Using an ohmmeter, test for continuity across the nor-

mally closed contacts. No reading indicates the control

is open - replace if necessary.

IF FOUND OPEN - REPLACE - DO NOT WIRE AROUND.

S-61B CHECKING HEATER FUSE LINK

(OPTIONAL ELECTRIC HEATERS)

Each individual heater element is protected with a one time

fuse link which is connected in series with the element. The

fuse link will open at approximately 333°.

WARNING

Disconnect ALL power before servicing.

1. Remove heater element assembly so as to expose fuse

link.

2. Using an ohmmeter, test across the fuse link for continu-

ity - no reading indicates the link is open. Replace as

necessary.

NOTE: The link is designed to open at approximately 333°F.

DO NOT WIRE AROUND - determine reason for failure.

S-62 CHECKING HEATER ELEMENTS

WARNING

Disconnect ALL power before servicing.

1. Disassemble and remove the heating element.

2. Visually inspect the heater assembly for any breaks in

the wire or broken insulators.

3. Using an ohmmeter, test the element for continuity - no

reading indicates the element is open. Replace as

necessary.

S-100 REFRIGERATION REPAIR PRACTICE

DANGER

Always remove the refrigerant charge in a proper

manner before applying heat to the system.

When repairing the refrigeration system:

WARNING

Disconnect ALL power before servicing.

1. Never open a system that is under vacuum. Air and

moisture will be drawn in.

2. Plug or cap all openings.

3. Remove all burrs and clean the brazing surfaces of the

tubing with sand cloth or paper. Brazing materials do not

flow well on oxidized or oily surfaces.

4. Clean the inside of all new tubing to remove oils and pipe

chips.

5. When brazing, sweep the tubing with dry nitrogen to

prevent the formation of oxides on the inside surfaces.

6. Complete any repair by replacing the liquid line drier in the

system, evacuate and charge.

BRAZING MATERIALS

IMPORTANT NOTE: Torch heat required to braze tubes of

various sizes is proportional to the size of the tube. Tubes of

smaller size require less heat to bring the tube to brazing

temperature before adding brazing alloy. Applying too much

heat to any tube can melt the tube. Service personnel must

use the appropriate heat level for the size of the tube being

brazed.

NOTE: The use of a heat shield when brazing is recommended

to avoid burning the serial plate or the finish on the unit. Heat

trap or wet rags should be used to protect heat sensitive

components such as service valves and TXV valves.

Copper to Copper Joints - Sil-Fos used without flux (alloy

of 15% silver, 80% copper, and 5% phosphorous). Recom-

mended heat 1400°F.

Copper to Steel Joints - Silver Solder used without a flux

(alloy of 30% silver, 38% copper, 32% zinc). Recommended

heat - 1200°F.

S-101 LEAK TESTING

(NITROGEN OR NITROGEN-TRACED)

To avoid the risk of fire or explosion, never use

oxygen, high pressure air or flammable gases for leak

testing of a refrigeration system.

WARNING

SERVICING

To avoid possible explosion, the line from the

nitrogen cylinder must include a pressure regulator

and a pressure relief valve. The pressure relief valve

must be set to open at no more than 150 psig.

WARNING

Pressure test the system using dry nitrogen and soapy water

to locate leaks. If you wish to use a leak detector, charge the

system to 10 psi using the appropriate refrigerant then use

nitrogen to finish charging the system to working pressure,

then apply the detector to suspect areas. If leaks are found,

repair them. After repair, repeat the pressure test. If no leaks

exist, proceed to system evacuation.

S-102 EVACUATION

WARNING

REFRIGERANT UNDER PRESSURE!

Failure to follow proper procedures may cause

property damage, personal injury or death.

This is the most important part of the entire service procedure.

The life and efficiency of the equipment is dependent upon the

thoroughness exercised by the serviceman when evacuating

air (non-condensables) and moisture from the system.

Air in a system causes high condensing temperature and

pressure, resulting in increased power input and reduced

performance.

Moisture chemically reacts with the refrigerant oil to form

corrosive acids. These acids attack motor windings and

parts, causing breakdown.

The equipment required to thoroughly evacuate the system is

a high vacuum pump, capable of producing a vacuum equiva-

lent to 25 microns absolute and a thermocouple vacuum

gauge to give a true reading of the vacuum in the system

NOTE: Never use the system compressor as a vacuum pump

or run when under a high vacuum. Motor damage could occur.

Do not front seat the service valve(s) with the

compressor open, with the suction line of the

comprssor closed or severely restricted.

WARNING

1. Connect the vacuum pump, vacuum tight manifold set

with high vacuum hoses, thermocouple vacuum gauge

and charging cylinder as shown.

2. Start the vacuum pump and open the shut off valve to the

high vacuum gauge manifold only. After the compound

gauge (low side) has dropped to approximately 29 inches

of vacuum, open the valve to the vacuum thermocouple

gauge. See that the vacuum pump will blank-off to a

maximum of 25 microns. A high vacuum pump can only

produce a good vacuum if its oil is non-contaminated.

3. If the vacuum pump is working properly, close the valve to

the vacuum thermocouple gauge and open the high and

low side valves to the high vacuum manifold set. With the

valve on the charging cylinder closed, open the manifold

valve to the cylinder.

4. Evacuate the system to at least 29 inches gauge before

opening valve to thermocouple vacuum gauge.

5. Continue to evacuate to a maximum of 250 microns.

Close valve to vacuum pump and watch rate of rise. If

vacuum does not rise above 1500 microns in three to five

minutes, system can be considered properly evacuated.

6. If thermocouple vacuum gauge continues to rise and

levels off at about 5000 microns, moisture and non-

condensables are still present. If gauge continues to rise

a leak is present. Repair and re-evacuate.

7. Close valve to thermocouple vacuum gauge and vacuum

pump. Shut off pump and prepare to charge.

S-103 CHARGING

WARNING

REFRIGERANT UNDER PRESSURE!

* Do not overcharge system with refrigerant.

* Do not operate unit in a vacuum or at negative

pressure.

Failure to follow proper procedures may cause

property damage, personal injury or death.

SERVICING

CAUTION

Use refrigerant certified to AHRI standards. Used

refrigerant may cause compressor damage and will

void the warranty. Most portable machines cannot

clean used refrigerant to meet AHRI standards.

CAUTION

Operating the compressor with the suction valve

closed will void the warranty and cause serious

compressor damage.

Charge the system with the exact amount of refrigerant.

Refer to the specification section or check the unit name-

plates for the correct refrigerant charge.

An inaccurately charged system will cause future prob-

lems.

1. When using an ambient compensated calibrated charg-

ing cylinder, allow liquid refrigerant only to enter the high

side.

2. After the system will take all it will take, close the valve

on the high side of the charging manifold.

3. Start the system and charge the balance of the refriger-

ant through the low side. DO NOT charge in a liquid

form.

4. With the system still running, close the valve on the charg-

ing cylinder. At this time, you may still have some liquid

refrigerant in the charging cylinder hose and will definitely

have liquid in the liquid hose. Reseat the liquid line core.

Slowly open the high side manifold valve and transfer the

liquid refrigerant from the liquid line hose and charging

cylinder hose into the suction service valve port. CARE-

FUL: Watch so that liquid refrigerant does not enter the

compressor.

5. With the system still running, reseat the suction valve

core, remove hose and reinstall both valve core caps.

6. Check system for leaks.

NOTE: This charging procedure can only be done in the

cooling mode of operation. (Early production "a" models

only.) All models with compressor process tube access

valve can be processed in heating cycle if this valve is

used.

When charging a remote condensing unit with a non-match-

ing evaporator coil, or a system where the charge quantity is

unknown, alternate charging methods must be used. These

systems must be charged according to subcooling or super-

heat.

mostatic expansion valves (TXV's) should be charged by sub-

cooling. See "Checking Subcooling and Superheat" sec-

tions in this manual.

Due to their design, Scroll compressors are inherently more

tolerant of liquid refrigerant.

NOTE: Even though the compressor section of a Scroll com-

pressor is more tolerant of liquid refrigerant, continued flood-

back or flooded start conditions may wash oil from the bear-

ing surfaces causing premature bearing failure.

If a restriction is located, replace the restricted part, replace

drier, evacuate and recharge.

S-104 CHECKING COMPRESSOR EFFICIENCY

The reason for compressor inefficiency is broken or dam-

aged suction and/or discharge valves, or scroll flanks on Scroll

compressors, reducing the ability of the compressor to pump

refrigerant vapor.

The condition of the valves or scroll flanks is checked in the

following manner.

1. Attach gauges to the high and low side of the system.

2. Start the system and run a "Cooling Performance Test.

If the test shows:

a. Below normal high side pressure.

b. Above normal low side pressure.

c. Low temperature difference across coil.

d. Low amp draw at compressor.

and the charge is correct. The compressor is faulty - replace

the compressor. NOTE: THIS TEST CANNOT BE DONE IN

THE HEATING MODE

Verification of proper rotation of Scroll Compressors is made

as follows.

SERVICING

NOTE: The compressor may run backwards (noisy opera-

tion) for 1 or 2 seconds at shutdown. This is normal and

does not harm the compressor.

1. Install gauges and verify that the suction pressure drops

while the discharge pressure increases.

2. Listen for normal compressor sound levels. Reverse rota-

tion results in elevated or unusual sound levels.

3. Reverse rotation will result in substantially reduced amp

draw from tabulated values.

To correct improper rotation, switch any two power supply

leads at the outdoor unit contactor.

The 3 phase Scroll Compressors are direction of rotation sen-

sitive. They will rotate in either direction depending on the

phasing of the power. There is no negative impact on durabil-

ity caused by operating 3 phase compressors in reversed

rotation. The compressors internal protector will trip, de-en-

ergizing the compressor. Continued operation of 3 phase scroll

compressors with the rotation reversed will contribute to com-

pressor failure. All 3 phase scroll compressors should be

checked for correct phase rotation.

S-105B THERMOSTATIC EXPANSION VALVE

The expansion valve is designed to control the rate of liquid

refrigerant flow into an evaporator coil in exact proportion to

the rate of evaporation of the refrigerant in the coil. The

amount of refrigerant entering the coil is regulated since the

valve responds to temperature of the refrigerant gas leaving

the coil (feeler bulb contact) and the pressure of the refrigerant

in the coil. This regulation of the flow prevents the return of

liquid refrigerant to the compressor.

The illustration below shows typical heat pump TXV/check

valve operation in the heating and cooling modes.

SERVICING

COOLING HEATING

THERMOSTATIC EXPANSION VALVES

Some TXV valves contain an internal check valve thus

eliminating the need for an external check valve and bypass

loop. The three forces which govern the operation of the valve

are: (1) the pressure created in the power assembly by the

feeler bulb, (2) evaporator pressure, and (3) the equivalent

pressure of the superheat spring in the valve.

0% bleed type expansion valves are used on indoor and

outdoor coils. The 0% bleed valve will not allow the system

pressures (High and Low side) to equalize during the shut

down period. The valve will shut off completely at approxi-

mately 100 PSIG.

30% bleed valves used on some other models will continue

to allow some equalization even though the valve has shut-off

completely because of the bleed holes within the valve. This

type of valve should not be used as a replacement for a 0%

bleed valve, due to the resulting drop in performance.

The bulb must be securely fastened with two straps to a clean

straight section of the suction line. Application of the bulb to

a horizontal run of line is preferred. If a vertical installation

cannot be avoided, the bulb must be mounted so that the

capillary tubing comes out at the top.

THE VALVES PROVIDED BY GOODMAN ARE DESIGNED

TO MEET THE SPECIFICATION REQUIREMENTS FOR

OPTIMUM PRODUCT OPERATION. DO NOT USE SUB-

STITUTES.

S-106 OVERFEEDING

Overfeeding by the expansion valve results in high suction

pressure, cold suction line, and possible liquid slugging of the

compressor.

If these symptoms are observed:

1. Check for an overcharged unit by referring to the cooling

performance charts in the servicing section.

2. Check the operation of the power element in the valve as

explained in S-110 Checking Expansion Valve Operation.

3. Check for restricted or plugged equalizer tube.

S-107 UNDERFEEDING

Underfeeding by the expansion valve results in low system

capacity and low suction pressures.

If these symptoms are observed:

1. Check for a restricted liquid line or drier. A restriction will

be indicated by a temperature drop across the drier.

2. Check the operation of the power element of the valve as

described in S-110 Checking Expansion Valve Operation.

S-108 SUPERHEAT

The expansion valves are factory adjusted to maintain 12 to

18 degrees superheat of the suction gas. Before checking

the superheat or replacing the valve, perform all the proce-

dures outlined under Air Flow, Refrigerant Charge, Expan-

sion Valve - Overfeeding, Underfeeding. These are the most

common causes for evaporator malfunction.

CHECKING SUPERHEAT

Refrigerant gas is considered superheated when its tempera-

ture is higher than the saturation temperature corresponding

to its pressure. The degree of superheat equals the degrees

of temperature increase above the saturation temperature at

existing pressure. See Temperature - Pressure Chart Table

1. Attach an accurate thermometer or preferably a thermo-

couple type temperature tester to the suction line at a

point at least 6" from the compressor.

2. Install a low side pressure gauge on the suction line ser-

vice valve at the outdoor unit.

3. Record the gauge pressure and the temperature of the

line.

4. Convert the suction pressure gauge reading to tempera-

ture by finding the gauge reading in Temperature - Pres-

sure Chart and reading to the left, find the temperature in

the °F. Column.

5. The difference between the thermometer reading and pres-

sure to temperature conversion is the amount of super-

heat.

EXAMPLE:

a. Suction Pressure = 84

b. Corresponding Temp. °F. = 50

c. Thermometer on Suction Line = 63°F.

To obtain the degrees temperature of superheat subtract 50.0

from 63.0°F.

The difference is 13° Superheat. The 13° Superheat would

fall in the ± range of allowable superheat.

SUPERHEAT ADJUSTMENT

The expansion valves used on Amana® brand coils are

factory set and are not field adjustable. If the superheat

setting becomes disturbed, replace the valve.

On systems using capillary tubes or flow control restrictors,

superheat is adjusted in accordance with the "DESIRED

SUPERHEAT vs. OUTDOOR TEMP" chart as explained in

section S-103 CHARGING.

S-109 CHECKING SUBCOOLING

Refrigerant liquid is considered subcooled when its tempera-

ture is lower than the saturation temperature corresponding

to its pressure. The degree of subcooling equals the degrees

of temperature decrease below the saturation temperature at

the existing pressure.

1. Attach an accurate thermometer or preferably a thermo-

couple type temperature tester to the liquid line as it

leaves the condensing unit.

2. Install a high side pressure gauge on the high side (liquid)

service valve at the front of the unit.

3. Record the gauge pressure and the temperature of the

line.

4. Convert the liquid line pressure gauge reading to tempera-

ture by finding the gauge reading in Temperature - Pres-

sure Chart and reading to the left, find the temperature in

the °F. Column.

5. The difference between the thermometer reading and

pressure to temperature conversion is the amount of

subcooling.

EXAMPLE:

a. Liquid Line Pressure = 260

b. Corresponding Temp. °F. = 120°

c. Thermometer on Liquid line = 109°F.

To obtain the amount of subcooling subtract 109°F from 120°F.

The difference is 11° subcooling. The normal subcooling

range is 9° - 13° subcooling for heat pumps units, 14 to 18 for

straight cool units.

S-110 CHECKING EXPANSION VALVE

OPERATION

1. Remove the remote bulb of the expansion valve from the

suction line.

2. Start the system and cool the bulb in a container of ice

water, closing the valve. As you cool the bulb, the suction

pressure should fall and the suction temperature will rise.

3. Next warm the bulb in your hand. As you warm the bulb,

the suction pressure should rise and the suction tempera-

ture will fall.

4. If a temperature or pressure change is noticed, the

expansion valve is operating. If no change is noticed, the

valve is restricted, the power element is faulty, or the

equalizer tube is plugged.

5. Capture the charge, replace the valve and drier, evacuate

and recharge.

SERVICING

S-111 CAPILLARY TUBES/RESTRICTOR ORIFICES

The capillary tubes/restrictor orifices used in conjunction with

the indoor and outdoor coil, are a predetermined length and

bore (I.D.).

They are designed to control the rate of liquid refrigerant flow

into an evaporator coil.

The amount of refrigerant that flows through the capillary tube/

restrictor orifice is regulated by the pressure difference

between the high and low sides of the system.

In the cooling cycle when the outdoor air temperature rises,

the high side condensing pressure rises. At the same time,

the cooling load on the indoor coil increases, causing the low

side pressure to rise, but at a slower rate.

Since the high side pressure rises faster when the tempera-

ture increases, more refrigerant flows to the evaporator,

increasing the cooling capacity of the system.

When the outdoor temperature falls, the reverse takes place.

The condensing pressure falls, and the cooling loads on the

indoor coil decrease, causing less refrigerant flow.

A strainer is placed on the entering side of the tubes to prevent

any foreign material from becoming lodged inside the capil-

lary tubes.

If a restriction should become evident, proceed as follows:

1. Capture the refrigerant charge.

2. Remove the capillary tubes/restrictor orifice or tube strainer

assembly. and replace.

3. Replace liquid line drier, evacuate and recharge.

Capillary Tubes/Orifice Assembly

CHECKING EQUALIZATION TIME

During the "OFF" cycle, the high side pressure bleeds to the

low side through the capillary tubes/restrictor orifices. Check

equalization time as follows:

1. Attach a gauge manifold to the suction and liquid line dill

valves.

2. Start the system and allow the pressures to stabilize.

3. Stop the system and check the time it takes for the high

and low pressure gauge readings to equalize.

If it takes more than seven (7) minutes the capillary tubes/

restrictor orifices are inoperative. Replace, install a liquid line

drier, evacuate and recharge.

S-112 CHECKING RESTRICTED LIQUID LINE

When the system is operating, the liquid line is warm to the

touch. If the liquid line is restricted, a definite temperature

drop will be noticed at the point of restriction. In severe cases,

frost will form at the restriction and extend down the line in the

direction of the flow.

Discharge and suction pressures will be low, giving the

appearance of an undercharged unit. However, the unit will

have normal to high subcooling.

Locate the restriction, replace the restricted part, replace

drier, evacuate and recharge.

S-113 OVERCHARGE OF REFRIGERANT

An overcharge of refrigerant is normally indicated by an

excessively high head pressure.

An evaporator coil, using an expansion valve metering device,

will basically modulate and control a flooded evaporator and

prevent liquid return to the compressor.

An evaporator coil, using a capillary tube metering device,

could allow refrigerant to return to the compressor under

extreme overcharge conditions. Also with a capillary tube

metering device, extreme cases of insufficient indoor air can

cause icing of the indoor coil and liquid return to the compres-

sor, but the head pressure would be lower.

There are other causes for high head pressure which may be

found in the "Service Problem Analysis Guide."

If other causes check out normal, an overcharge or a system

containing non-condensables would be indicated.

If this system is observed:

1. Start the system.

2. Remove and capture small quantities of gas from the

suction line dill valve until the head pressure is reduced to

normal.

3. Observe the system while running a cooling performance

test. If a shortage of refrigerant is indicated, then the

system contains non-condensables.

S-114 NON-CONDENSABLES

If non-condensables are suspected, shut down the system

and allow the pressures to equalize. Wait at least 15

minutes. Compare the pressure to the temperature of the

coldest coil since this is where most of the refrigerant will be.

If the pressure indicates a higher temperature than that of the

coil temperature, non-condensables are present.

Non-condensables are removed from the system by first

removing the refrigerant charge, replacing and/or installing

liquid line drier, evacuating and recharging.

S-115 COMPRESSOR BURNOUT

When a compressor burns out, high temperature develops

causing the refrigerant, oil and motor insulation to decom-

pose forming acids and sludge.

If a compressor is suspected of being burned-out, attach a

refrigerant hose to the liquid line dill valve and properly remove

and dispose of the refrigerant.

SERVICING

NOTICE

Violation of EPA regulations may result in fines

or other penalties.

Now determine if a burn out has actually occurred. Confirm

by analyzing an oil sample using a Sporlan Acid Test Kit, AK-

3 or its equivalent.

Remove the compressor and obtain an oil sample from the

suction stub. If the oil is not acidic, either a burnout has not

occurred or the burnout is so mild that a complete clean-up

is not necessary.

If acid level is unacceptable, the system must be cleaned by

using the clean-up drier method.

CAUTION

Do not allow the sludge or oil to contact the skin.

Severe burns may result.

NOTE: The Flushing Method using R-11 refrigerant is no

longer approved by Goodman Company, L.P.

Suction Line Drier Clean-Up Method

Use AMANA® brand part number RF000127 suction line filter

drier kit. This drier should be installed as close to the

compressor suction fitting as possible. The filter must be

accessible and be rechecked for a pressure drop after the

system has operated for a time. It may be necessary to use

new tubing and form as required.

NOTE: At least twelve (12) inches of the suction line

immediately out of the compressor stub must be discarded

due to burned residue and contaminates.

1. Remove compressor discharge line strainer.

2. Remove the liquid line drier and expansion valve.

3 Purge all remaining components with dry nitrogen or

carbon dioxide until clean.

4. Install new components including liquid line drier.

5. Braze all joints, leak test, evacuate, and recharge sys-

tem.

6. Start up the unit and record the pressure drop across the

drier.

7. Continue to run the system for a minimum of twelve (12)

hours and recheck the pressure drop across the drier.

Pressure drop should not exceed 6 PSIG.

8. Continue to run the system for several days, repeatedly

checking pressure drop across the suction line drier. If

the pressure drop never exceeds the 6 PSIG, the drier has

trapped the contaminants. Remove the suction line drier

from the system.

9. If the pressure drop becomes greater, then it must be

replaced and steps 5 through 9 repeated until it does not

exceed 6 PSIG.

NOTICE: Regardless, the cause for burnout must be deter-

mined and corrected before the new compressor is started.

S-120 REFRIGERANT PIPING

The piping of a refrigeration system is very important in

relation to system capacity, proper oil return to compressor,

pumping rate of compressor and cooling performance of the

evaporator.

This long line set application guideline applies to all AHRI

listed R22 air conditioner and heat pump split system

matches of nominal capacity 18,000 to 60,000 Btuh. This

guideline will cover installation requirements and additional

accessories needed for split system installations where the

line set exceeds 50 feet in actual length.

Additional Accessories:

1. Crankcase Heater- a long line set application can

critically increase the charge level needed for a system.

As a result, the system is very prone to refrigerant

migration during its off-cycle and a crankcase heater will

help minimize this risk. A crankcase heater is recom-

mended for any long line application (50 watt minimum).

2. TXV Requirement: All line set applications over 50 ft will

require a TXV.

3. Hard Start Assist- increased charge level in long line

applications can require extra work from the compressor

at start-up. A hard start assist device may be required to

overcome this.

4. Liquid Line Solenoid - A long line set application can

critically increase the charge level needed for a system.

As a result, the system is very prone to refrigerant

migration during its off-cycle and a liquid line solenoid will

help minimize this. A liquid line solenoid is recommended

for any long line application on straight cooling units.

Tube Sizing:

1. In long line applications, the “equivalent line length” is the

sum of the straight length portions of the suction line plus

losses (in equivalent length) from 45 and 90 degree

bends. Select the proper suction tube size based on

equivalent length of the suction line (see Tables 9 &

10) and recalculated system capacity.

Equivalent length = Length horizontal + Length vertical +

Losses from bends (see Table 11)

2. For any residential split system installed with a long

line set, the liquid line size must never exceed 3/8".

Limiting the liquid line size to 3/8" is critical since an

increased refrigerant charge level from having a larger

liquid line could possibly shorten a compressor’s lifespan.

3. Single Stage Condensing Unit: The maximum length

of tubing must not exceed 150 feet.

•50 feet is the maximum recommended vertical differ-

ence between the condenser and evaporator when the

evaporator is above the condenser. Equivalent length is

not to exceed 150 feet.

• The vertical difference between the condenser and

evaporator when the evaporator is below the condenser

can approach 150 feet, as long as the equivalent length

does not exceed 150 feet.

SERVICING

• The distance between the condenser and evaporator in

a completely horizontal installation in which the indoor

and outdoor unit do not differ more than 10 feet in

vertical distance from each other can approach 150

feet, as long as the equivalent length does not exceed

150 feet.

4. Two-Stage Condensing Unit: The maximum length of

tubing must not exceed 75 feet here indoor coil is located

above the outdoor unit.

NOTE: When the outdoor unit is located above the

indoor coil, the maximum vertical rise must not exceed

25 feet. If the maximum vertical rise exceeds 25 feet,

premature compressor failure will occur due to inad-

equate oil return.

5. Vibration and Noise: In long line applications, refrigerant

tubing is highly prone to transmit noise and vibration to the

structure it is fastened to. Use adequate vibration-isolat-

ing hardware when mounting line set to adjacent struc-

ture.

Most refrigerant tubing kits are supplied with 3/8"-thick

insulation on the vapor line. For long line installations over 50

feet, especially if the line set passes through a high ambient

temperature, ½”-thick suction line insulation is recommended

to reduce loss of capacity. The liquid line should be insulated

if passing through an area of 120°F or greater. Do not attach

the liquid line to any non-insulated portion of the suction line.

Table 9 lists multiplier values to recalculate system-cooling

capacity as a function of a system’s equivalent line length (as

calculated from the suction line) and the selected suction

tube size. Table 10 lists the equivalent length gained from

adding bends to the suction line. Properly size the suction

line to minimize capacity loss.

Installation Requirements

1. In a completely horizontal installation with a long line set

where the evaporator is at the same altitude as (or slightly

below) the condenser, the line set should be sloped

towards the evaporator. This helps reduce refrigerant

migration to the condenser during a system’s off-cycle.

2. For a system installation where the evaporator is above

the condenser, an inverted vapor line trap should be

installed on the suction line just before the inlet to the

evaporator (see Fig 6). The top of the inverted loop must

be slightly above the top of the evaporator coil and can be

created simply by brazing two 90° long radius elbows

together, if a bending tool is unavailable. Properly support

and secure the inverted loop to the nearest point on the

indoor unit or adjacent structure.

Fig 6. Evaporator unit with inverted vapor loop

SERVICING

3. An oil trap is required at the evaporator only if the

condenser is above the evaporator. Preformed oil

traps are available at most HVAC supply houses, or oil

traps may be created by brazing tubing elbows together

(see diagram below). Remember to add the equivalent

length from oil traps to the equivalent length calculation

of the suction line. For example, if you construct an oil

trap using two 45° elbows, one short and one long 90°

elbow in a ¾” diameter suction line, the additional

equivalent length would be 0.7+ 0.7+1.7+1.5, which

equals 4.6 feet (refer to table 9).

4. Low voltage wiring. Verify low voltage wiring size is

adequate for the length used since it will be increased in

a long line application.

System Charging

R22 condensers are factory charged for 15 feet of line set. To

calculate the amount of extra refrigerant (in ounces) needed

for a line set over 15 feet, multiply the additional length of line

set by 0.6 ounces. Note for the formula below, the linear feet

of line set is the actual length of liquid line (or suction line,

since both should be equal) used, not the equivalent length

calculated for the suction line.

Extra refrigerant needed =

(Linear feet of line set – 15 ft) x X oz/ft.

Where X = 0.6 for 3/8" liquid tubing

Remember, for condensers with a liquid valve connection

less than 3/8" diameter, 3/8" liquid tubing is required for a

line set longer than 25 feet.

Follow the charging procedures in the outdoor unit I/O manual

to ensure proper superheat and sub-cooling levels, especially

on a system with a TXV installed in the indoor unit. Heat

pumps should be checked in both heating and cooling mode

for proper charge level. This guideline is meant to provide

installation instructions based on most common long line set

applications. Installation variables may affect system opera-

tion.

NO ADDITIONAL COMPRESSOR OIL IS NEEDED FOR

LONG LINE SET APPLICATIONS

ON RESIDENTIAL SPLIT SYSTEMS.

S-122 REVERSING VALVE REPLACEMENT

Remove the refrigerant charge from the system.

When brazing a reversing valve into the system, it is of

extreme importance that the temperature of the valve does

not exceed 250° F. at any time.

Wrap the reversing valve with a large rag saturated with water.

"Re-wet" the rag and thoroughly cool the valve after each

brazing operation of the four joints involved. The wet rag

around the reversing valve will eliminate conducting of heat to

the valve body when brazing the line connection.

The use of a wet rag sometimes can be a nuisance. There are

commercial grades of heat absorbing paste that may be

substituted.

After the valve has been installed leak test, evacuate and

recharge.

S-202 DUCT STATIC PRESSURES AND/OR

STATIC PRESSURE DROP

ACROSS COILS

This minimum and maximum allowable duct static pressure

for the indoor sections are found in the specifications section.

Tables are also provided for each coil, listing quantity of air

(CFM) versus static pressure drop across the coil.

Too great an external static pressure will result in insufficient

air that can cause icing of the coil. Too much air can cause

poor humidity control and condensate to be pulled off the

evaporator coil causing condensate leakage. Too much air

can also cause motor overloading and in many cases this

constitutes a poorly designed system.

SERVICING

S-203 AIR HANDLER EXTERNAL STATIC

To determine proper air movement, proceed as follows:

1. Using a draft gauge (inclined manometer), measure the

static pressure of the return duct at the inlet of the unit,

(Negative Pressure).

2. Measure the static pressure of the supply duct, (Positive

Pressure).

3. Add the two readings together.

TOTAL EXTERNAL STATIC

NOTE: Both readings may be taken simultaneously and read

directly on the manometer if so desired.

4. Consult proper table for quantity of air.

If external static pressure is being measured on a furnace to

determine airflow, supply static must be taken between the

"A" coil and the furnace.

Air Flow

TOTAL EXTERNAL STATIC

S-204 COIL STATIC PRESSURE DROP

1. Using a draft gauge (inclined manometer), connect the

positive probe underneath the coil and the negative probe

above the coil.

2. A direct reading can be taken of the static pressure drop

across the coil.

3. Consult proper table for quantity of air.

STATIC PRESSURE DROP

If the total external static pressure and/or static pressure drop

exceeds the maximum or minimum allowable statics, check

for closed dampers, dirty filters, undersized or poorly laid out

duct work.
