RECEIVINGANDINSTALLATION

Stepl--Check Equipment

IDENTIFY UNIT

The unit model number and serial number are printed on the unit

informative plate. Check this information against shipping papers.

INSPECT SHIPMENT

Inspect for shipping damage while unit is still on shipping pallet. If

unit appears to be damaged or is torn loose from its anchorage, have

it examined by transportation inspectors before removal. Forward

claim papers directly to transportation company. Manufacturer is

not responsible for any damage incurred in transit. Check all items

against shipping list. Immediately notify the nearest Payne office if

any item is missing. To prevent loss or damage, leave all parts in

original packages until installation.

Step 2--Provide Unit Support

For hurricane tie downs, contact distributor for details and PE

(Professional Engineering) Certificate, if required.

SLAB MOUNT

Place the unit on a solid, level concrete pad that is a minimum of 4

in. thick with 2 in. above grade. The slab should extend

approximately 2 in. beyond the casing on all 4 sides of the unit. Do

not secure the unit to the slab except when required by local codes.

A 6-in. wide gravel apron should be used around the flat surface to

prevent airflow blockage by grass or shrubs. The unit should be

level To within 1/4 in. This is necessary for the unit drain to function

properly.

GROUND MOUNT

The unit may be installed either on a slab or placed directly on the

ground if local codes permit. Place the unit on level ground prepared

with gravel for condensate discharge.

Step 3--Provide Clearances

The required minimum service clearances are shown in Fig. 5.

Adequate ventilation and outdoor air must be provided.

The outdoor fan draws air through the outdoor coil and discharges

it through the top fan grille. Be sure that the fan discharge does not

recirculate to the outdoor coil. Do not locate the unit in either a

corner or under an overhead obstruction. The minimum clearance

under a partial overhang (such as a normal house overhang) is 48 in.

above the unit top. The maximum horizontal extension of a partial

overhang must not exceed 48 in.

IMPORTANT: Do not restrict outdoor airflow. An air restriction at

either the outdoor-air inlet or the fan discharge may be detrimental

to compressor life.

Do not place the unit where water, ice. or snow from an overhang

or roof will damage or flood the unit. Do not install the unit on

carpeting or other combustible materials. Slab-mounted units

should be at least 4 in. above the highest expected water and runoff

levels. Do not use unit if it has been under water.

Step 4--Place Unit

Unit can be moved with the rigging holds provided in the unit base.

Refer to Table 1 for operating weights. Use extreme caution to

prevent damage when moving the unit. Unit must remain in an

upright position during all moving operations. The unit nmst be

level within 1/4 in. for proper condensate drainage; the

ground-level pad must be level before setting the unit in place.

When a field-fabricated support is used. be sure that the support is

level and that it properly supports the unit.

Step 5--Select and Install Ductwork

The design and installation of the duct system must be in accordance

with the standards of the NFPA for installation of non-residence

type air conditioning and ventilating systems. NFPA 90A or

residence type, NFPA 90B and/or local codes and ordinances.

Select and size ductwork, supply- air registers, and return air grilles

according to ASHRAE (American Society of Heating,

Refrigeration, and Air Conditioning Engineers) recommendations.

Use the duct flanges provided on the supply- and return-air

openings on the side of the unit. See Fig. 5 for connection sizes and

locations. The 14-in. round duct collars are shipped inside the unit

attached to the base pan in the indoor blower compartment. They are

field-installed and must be removed from the indoor blower

compartment prior to start-up, even if they are not used for

installation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury

or death.

Before performing service or maintenance operations on the

system, turn off main power to unit and install lockout tag.

Units are dedicated side supply products. They are not convertible

to vertical air supply. A field-supplied plenum must be used to

convert to vertical air discharge.

Step 6--Connect Condensate Drain

NOTE: When installing condensate drain connection be sure to

comply with local codes and restrictions.

Unit removes condensate through a 1-3/64 in. ID hole (using

3/4-in. OD piping or tubing) which is located at the end of the unit.

See Fig. 5 for location of condensate connection.

Condensate water can be drained directly onto tire roof in rooftop

installations (where permitted) or onto a gravel apron in ground

level installations. Install a field-supplied condensate trap at end of

condensate connection to ensure proper drainage. Make sure that

the outlet of the trap is at least 1 in. lower than the drain pan

condensate connection to prevent the pan from overflowing (See

Fig. 3 and 4). When using a gravel apron, make sure it slopes away

from the unit.

If the installation requires draining the condensate water away from

the unit, install a 2-in. trap using a 3/4-in. OD tubing or pipe. (See

Fig. 3 and 4.) Make sure that the outlet of the trap is at least 1 in.

lower than the unit drain-pan condensate connection to prevent the

pan from overflowing. Prime the trap with water. Connect a drain

tube using a minimum of 3/4-in. PVC, 3/4-in. CPVC, or 3/4-in.

copper pipe (all field supplied). Do not undersize the tube. Pitch the

drain tube downward at a slope of at least 1 in. for every 10 ft of

horizontal run. Be sure to check the drain tube for leaks. Prinm trap

at the beginning of the cooling season start-up. Allowable glues for

condensate trap connection are: Standard ABS, CPVC, or PVC

Step 3--Refrigerant Charge

Refrigerant Charge --Amount of refrigerant charge is listed on unit

nameplate and in Table 1. Refer to Payne Refrigerant Service

Techniques Manual, Refrigerants section. Unit panels must be in

place when unit is operating during charging procedure. Unit must

operate a minimum of 15 minutes before checking charge.

NO CHARGE

Refer to Payne Refrigerant Service Techniques. Use standard

evacuating techniques. After evacuating system, weigh in the

specified amount of refrigerant (refer to Table 1).

LOW CHARGE COOLING

024-042 units:

1. Measure suction line pressure by attaching a gauge to the

service port.

2. Measure the suction line temperature by attaching a

temperature sensing device to it.

3. Insulate the temperature sensing device so that the outdoor

ambient doesn't affect the reading.

4. Locate the measured suction line pressure in the top row of

Table 7 and the measured outdoor ambient temperature in

the left colunm of the table. Based on the two values,

determine the required suction line temperature.

5. If the measured suction line temperature is greater than the

tabulated temperature, add charge in the system.

048 and 060 units:

1. Measure discharge line pressure by attaching a gauge to the

service port.

2. Measure the liquid line temperature by attaching a

temperature sensing device to it.

3.Insulatethetemperaturesensingdevicesothattheoutdoor

Step4--IndoorAirflowand Airflow Adjustments

NOTE: For cooling operation, the recommended airflow is 350 to

450 cfm for each 12,000 Btuh of rated cooling capacity.

Table 6 shows dry coil air delivery for horizontal discharge units.

Tables 8-10 show pressure drops.

NOTE: Be sure that all supply- and return-air grilles are open. free

from obstructions, and adjusted properly.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury

or death.

Disconnect electrical power to the unit and install lockout tag

before changing blower speed.

Airflow can be changed by changing the lead connections of the

blower motor.

All PH3Z blower motors are factory wired for rated airflow

operation.

FOR 208/230V BLOWER MOTORS

The motor lead speed connections are as follows:

SIZE RATED AIRFLOW HIGH AIRFLOW

030 Tap 2 Tap 4

036 Tap 1 Tap 3

042 Tap 2 Tap 4

RATED AIRFLOW HIGH AIRFLOW

SIZE Low High Low High

Stage Stage Stage Stage

048 Tap 1 Tap 3 Tap 2 Tap 4

060 Tap 1 Tap 3 Tap 2 Tap 4

Step 5--Unit Controls

All compressors have the following internal-protection controls.

HIGH-PRESSURE RELIEF VALVE

This valve opens when the pressure differential between the low and

high side becomes excessive.

LOSS OF CHARGE SWITCH

Located on the outdoor liquid line is a low-pressure switch which

functions as a loss-of-charge switch. This switch contains a

Schrader core depressor. This switch opens at 7 psig and closes at 22

psig. No adjustment is necessary.

COMPRESSOR OVERLOAD

This overload interrupts power to the compressor when either the

current or internal temperature become excessive, and

automatically resets when the internal temperature drops to a safe

level.

This overload may require up to 60 minutes (or longer) to reset:

therefore, if the internal overload is suspected of being open,

disconnect the electrical power to the unit and check the circuit

through the overload with an ohmmeter or continuity tester.

COMPRESSOR ROTATION

On 3-Phase units it is important to be certain compressor is rotating

in the proper direction. To determine whether or not compressor is

rotating in the proper direction:

1. Connect service gauges to suction and discharge pressure

fittings.

2. Energize the compressor.

3. The suction pressure should drop and the discharge pressure

should rise, as is normal on any start-up.

If the suction pressure does not drop and the discharge pressure does

not rise to normal levels:

1. Turn off power to the unit and tag disconnect.

2. Reverse any two of the unit power leads.

3. Turn on power to the unit.

The suction and discharge pressure levels should now move to their

normal start-up levels.

NOTE: When the compressor is rotating in the wrong direction, the

unit makes an elevated level of noise and does not provide cooling.

Step 6--Sequence of Operation

FAN OPERATION

The FAN switch on the thermostat controls indoor fan operation.

When the FAN switch is placed in the ON position, the IFR

(indoor-fan relay) is energized through the Gterminal on the

thermostat. The normally-open contacts close, which then provide

power to the indoor (evaporator) fan motor (IFM). The IFM will run

continuously when the FAN switch is set to ON.

When the FAN switch is set to AUTO, the thermostat deenergizes

the IFR (provided there is not a call for cooling). The contacts open

and the IFM is deenergized. The IFM will be energized only when

there is a call for cooling, in heat pump heating mode or if the unit

is equipped with accessory electric heat, the indoor-fan motor will

also run while the accessory electric heat is energized.

NOTE: Some units are equipped with a time-delay relay. On these

units, the indoor fan remains on for 30 seconds after G or Y is

deenergized.

COOLING OPERATION (SIZES 024-042)

With a call for cooling (Y/Y2), the indoor fan energizes immediately

whereas the contactor energizes after a 5 minute time delay (in case

of initial start-up) starting the compressor and the outdoor fan

motor. When the cooling demand is met. Y/Y2 de-energizes,

shutting the compressor, indoor fan and the outdoor fan.

COOLING OPERATION (SIZES 048 AND 060)

These units utilize a 2 stage indoor thermostat. With a first stage call

for cooling (Y1), the indoor fan (low stage) energizes immediately

whereas the contactor energizes after a 5 minute time delay (in case

of an initial start-up) starting the compressor (low stage) and the

outdoor fan motor. If the low stage operation cannot satisfy the

cooling demand, the second stage cooling (Y2) energizes switching

the compressor into high stage cooling through energizing an

internal solenoid valve inside the scroll compressor and switching

the indoor fan into high stage. When second stage cooling is

satisfied, Y2 de-energizes switching the compressor and the indoor

fan into low stage cooling. When the low stage cooling demand is

met, Y1 de-energizes shutting the compressor, indoor fan and the

outdoor fan.

HEATING OPERATION (SIZES 024-042)

With a call for heating (Y1), the indoor fan (low stage) energizes

immediately whereas the contactor energizes after a 5 minute time

delay (in case of initial start-up) starting the compressor and the

outdoor fan motor. If Y/Y2 cannot satisfy the heating demand, the

auxiliary or backup heat (W2) energizes. In case of staged heating,

W3 is energized if the demand is not met. The highest airflow

selected is run while the electric heat is in operation. When heating

demand is met. W3. W2 and Y/Y2 sequentially de-energize

shutting the compressor, indoor fan and the outdoor fan.

HEATING OPERATION (SIZES 048 AND 060)

With a first stage call for heating (Y1), the indoor fan (low stage)

energizes immediately whereas the contactor energizes after a 5

minute time delay (in case of initial start-up) starting the compressor

(low stage) and the outdoor fan motor. If the low stage operation

cannot satisfy the heating demand, the second stage heating (Y2)

energizes switching the compressor into high stage heating through

energizing an internal solenoid valve inside the scroll compressor

and switching the indoor fan into high stage. The auxiliary or

backup heat is controlled by a third stage (W2). If the demand is not

met, W3 is energized in case of staged heating. When heating

demand is satisfied, W3, W2 and Y2 sequentially de-energize

switching the compressor and the indoor fan into low stage heating.

When the low stage heating demand is met, Y1 de-energizes

shutting down the compressor, indoor fan and the outdoor fan.

CONTINUOUS FAN

With the continuous Indoor fan option selected on the thermostat.

G is continuously energized. In case of 024-042 units, the selected

airflow setting is provided. In case of 048 and 060 units, the system

runs low stage (Y1) airflow for continuous fan operation.

DEFROST

Defrost board (DB) is a time and temperature control, which

includes a field-selectable time period between checks for defrost

(30, 60, 90 and 120 minutes). The time period is factory-set at 60

minutes and should only be adjusted by a trained service person.

Electronic timer and defrost cycle start only when contactor is

energized and defrost thermostat (DFT) is closed.

Defrost mode is identical to Cooling mode. The outdoor fan motor

stops because of "OF1" and "OF2" contacts opening on the defrost

board, abank of optional electric heat turns on to warm air supplying

the conditioned space.

ELECTRIC RESISTANCE HEATING

If accessory electric heaters are installed, on a call for "Emergency

Heat" the thermostat energizes W which energizes the heater relay

and in turn energizes the electric heaters. The IFR is energized

which starts the indoor-fan motor. If the heaters are staged, W2 is

energized when the second stage of heating is required. When the

need for heating is satisfied, the heater and IFM are de-energized.

Step 4--Outdoor Coil, Indoor Coil, and Condensate Drain

Pan

Inspect the condenser coil. evaporator coil and condensate drain

pan at least once each year.

The coils are easily cleaned when dry; therefore, inspect and clean

the coils either before or after each cooling season. Remove all

obstructions, including weeds and shrubs, that interfere with the

airflow through the condenser coil.

Straighten bent fins with afin comb. If coated with dirt or lint, clean

the coils with avacuum cleaner, using the soft brush attachment. Be

careful not to bend the fins. If coated with oil or grease, clean the

coils with amild detergent and water solution. Rinse coils with clear

water, using a garden hose. Be careful not to splash water on motors,

insulation, wiring, or air filter(s). For best results, spray condenser

coil fins from inside to outside the unit. On units with an outer and

inner condenser coil, be sure to clean between the coils. Be sure to

flush all dirt and debris from the unit base.

Inspect the drain pan and condensate drain line when inspecting the

coils. Clean the drain pan and condensate drain by removing all

foreign matter from the pan. Flush the pan and drain trough with

clear water. Do not splash water on the insulation, motor, wiring, or

air filter(s). If the drain trough is restricted, clear it with a "plumbers

snake" or similar probe device.

Step 5--Outdoor Fan

Step 6--Electrical Controls and Wiring

Inspect and check the electrical controls and wiring annually. Be

sure to turn off the electrical power to the unit.

Remove access panel to locate all the electrical controls and wiring.

Check all electrical connections for tightness. Tighten all screw

connections. If any smoky or burned connections are noticed,

disassemble the connection, clean all the parts, re-strip the wire end

and reassemble the connection properly and securely.

Check to ensure no wires are touching refrigerant tubing or sharp

sheet metal edges. Move and secure wires to isolate from tubing and

sheet metal edges.

After inspecting the electrical controls and wiring, replace all the

panels. Start the unit, and observe at least one complete cooling

cycle to ensure proper operation. If discrepancies are observed in

operating cycle, or if a suspected malfunction has occurred, check

each electrical component with the proper electrical

instrumentation. Refer to the unit wiring label when making these

checks.

Step 7--Refrigerant Circuit

Inspect all refrigerant tubing connections and the unit base for oil

accumulation annually. Detecting oil generally indicates a

refrigerant leak.

If oil is detected or if low performance is suspected, leak test all

refrigerant tubing using an electronic leak detector, or liquid-soap

solution.If a refrigerantleakis detected,referto Checkfor

RefrigerantLeakssection.

Ifnorefrigerantleaksarefoundandlowperformanceissuspected,

Step 9--Metering Devices

Refrigerant cooling metering device is an AccuRater (024-042) or

TXV (048 and 060) located upstream of the indoor coil distributor

assembly. Refrigerant heating mode metering device is an

AccuRater located upstrem of the outdoor coil distributor assembly.

Step lO--Liquid Line Strainers

The liquid line strainers (to protect metering devices) are made of

wire mesh and are located in the liquid lines on the inlet side of the

metering devices.

Step ll--High Flow Valves

High flow valves are located on the compressor hot gas and suction

tubes. Large black plastic caps distinguish these valves with

O - rings located inside the caps. These valves can not be accessed for

service in the field. Ensure the plastic caps are in place and tight or

the possibility of refrigerant leakage could occur.
