AUTO FAN (Cooling Demand)
Control Panel Operation Instructions
During the (SYSTEM mode COOL or HEAT), the fan speed automatically varies depending on the difference between the unit's set point on the control
panel and the actual room temperature. Let me explain. Say for example, you’re working in your garage and you open the big door for several minutes. The
system will sense a wide difference between the set point and the actual room temperature. When this occurs, the system fan speed increases to HIGH for
a period of time. The fan speed decreases, in step, as the temperature difference decreases. When the room temperature matches the system's set point,
fan speed returns to the lowest setting, and if the fan mode is on AUTO FAN, the fan will stop.

FAN SPEED Button - Used to sequentially select new fan speed, plus
AUTO operation. When the FA N
SPEED button is pressed, the fan speed icon
(triangle) changes to indicate the new speed level. Fan speed automatically
varies depending on the set temperature on the control panel and the actual
room temperature. For example if there is a big difference between your
set temperature and the actual room temperature, the system fan speed
increases to HIGH. It remains at this speed until the room temperature
matches the set temperature.
UP and DOWN Arrows - Pressing either the (UP) or (DOWN)

Compressor Operation:
Cooling Mode
Once the ambient temperature rises past the cool demand threshold (Cool Set Point + 1.5 ˚F) (see gure below), and
the compressor is not locked out, the cooling cycle begins. As shown in the gure below, the fan is started 5 seconds
prior to the compressor. Once the ambient temperature has been lowered to the cool set point (Cool Set Point minus
.25 ˚F), the cooling cycle starts to terminate by shutting off the compressor. After a 30 seconds delay, the fan is shut
off. (See gure below for graphic details)
The reversing valve only changes when required
to provide cooling or heat pump. The RV valve
stays in it's last state until required to change.

Heating Mode Control Operation
There are two heating methods: Heat Pump and Electric Resistance Heat.
There are 3 types of units that provide heating: Heat Pump Only (Model YS10M10)
Heat Pump with Electric Heat and Cool with Electric Heat.
Heat Control Operation Heat Pump Only Unit (YS10M10 has no electric heat back-up)
Once the ambient temperature falls below the Heating Demand Threshold
(1.5 ˚F Below the Heat Set Point Temperature), the heating cycle begins. The fan is turned on 5 seconds before.
Once the ambient temperature has been raised to the Heat Satised Point (Set point + .25 ˚F), the compressor is
turned off. The fan is turned off 15 seconds later. The gure below illustrates the basic heat pump operation.
YS10M10 Heat Pump Defrost Cycle Operation
The defrost in this unit is an active reverse cycle. The defrost control runs in the background and determines when a
defrost cycle is required. Once initiated, the defrost cycle runs to completion.
The defrost cycle can only be initiated when the heat pump is in operation. The compressor will not be turned off to
avoid activating the compressor's time delay. The reversing valve will be switched to the cool mode position. The
indoor fan/blower will be turned off. Once the defrost cycle is nished, the system should re-enter a heating demand
cycle if required.
When the heat pump run time is 60 minutes or greater with an outdoor coil temperature of 26F degrees or lower, the
control will run an active defrost for up to 6 minutes. When the temperature at the outdoor coil reaches 54F degrees,
the heat pump heat will resume.
25
This heating is more complex due to the possibility of two heating methods. If the ambient indoor temperature is be-
low the heat demand threshold (1.5˚F below the heat set point temperature), and the compressor is not locked out,
turn on compressor. If the ambient indoor temperature is 0.25˚F above the heat set point turn off the compressor.
If the compressor is locked out & electric heat is available:
1. Turn on the electric heat until the compressor is not locked out.
2. After lockout, turn off the electric heat, wait 5 seconds, then turn on the compressor.
If Electric Heat is Available
After the Heat button is initially pressed, the unit will run the electric heater rst until the initial set point is satised (Hot
Start Feature). After the initial start, the unit will switch to Heat Pump heat and decide between Heat Pump heat and
Electric heat based on the following two monitored conditions:
Condition 1
If the outdoor coil temperature sensor drops to 30 ˚F or less for 2 consecutive minutes, the unit will switch to electric heat
if available. Thereafter, the unit will switch back to Heat Pump heat if the outdoor coil temperature sensor rises to 45 ˚F or
greater.
If Electric Heat is not available (out of order) and the outdoor coil temperature sensor drops to 30 ˚F or less for 2
consecutive minutes, then the compressor and fan will turn off. Thereafter, the unit will switch back to Heat Pump heat if
the outdoor coil temperature rises to 45 ˚F or greater.
Heat Pump With Electric Heat Operation
26
Condition 2
If the Δ (delta) (set point temperature minus the ambient indoor temperature) is greater than 5 ˚F, then the unit will switch
to electric heat, if available. The unit will continue to operate with electric heat until the heat demand is satised. Note that
the electric heat switches on after the Δ temp passes 5°F and the heat pump switches off. Also note that the electric heat
will run until the heat demand is satised. When another heat demand cycle is initiated, the heat pump will run unless the Δ
temp is greater than the electric heat threshold.
Automatic Emergency Heat
If the sealed system fails with a bad reversing valve or anything that causes the indoor coil to get colder than the indoor
ambient temperature:
1) If the indoor coil thermistor senses a 5 degree temperature drop as compared to the ambient temperature thermistor
and this lasts up to 5 minutes, the control board will switch the unit to electric heat and continue heating with it.
2) At this point, error code 15 is generated; heat pump failure. Indoor coil temperature lower than indoor ambient
temperature for 5 or more degrees for 5 consecutive minutes.
Note: It is Ok to continue to use the unit with the electric heater until the heat pump is repaired.
Electric Heat Operation in Cool with Electric Heat Units
When in the Heat mode, with and without Fan Mode Auto (Fan cycling):
If the indoor ambient temperature is below the Heat Demand Threshold (Heat Set Point minus 1.5 ˚F), turn on electric heat.
If Ambient is 0.3 ˚F above the Heat Set Point turn off the electric heat.
System Mode Auto
This mode provides automatic change over between cool and heat. The auto mode runs based on the room ambient
temperature vs. the Demand Thresholds. It is only available in Heat-Cool Unit.
Notes:
There is a buffer zone between the cool and heat set points where no heating or cooling is allowed to occur. It is critical
that the Cool Demand Threshold be greater than the Heat Demand Threshold by a minimum of 3° while in the Auto
System Mode. For example, if a user enters a value for the Auto Cooling Set Point that violates the minimum Δ rule, the
Auto Heating Set Point will adjust accordingly.
Automatic Change Over Delay (Cool with Heat Units)
The change over delay ensures that any system heating or cooling over shoot does not trigger an opposite demand cycle.
The change over delay = 15 min. This timer blocks the opposite demand cycle from running until the timer expires. As an
example, if the last demand was a cool cycle, and another cool cycle is requested, the timer will not block the request.
However, if the last demand cycle was a cool cycle, and heat cycle is requested, the timer will block the request until the
change over delay is expired.
Heat Pump With Electric Heat Operation (Continued)

Compressor Lock Out Time
The lockout feature ensures that the compressor is de-energized for a period of time. The timer varies randomly
from 180 to 240 seconds
The compressor lockout is initiated every time the compressor is “off” due to:
(1) Satisfying the temperature set point
(2) Changing mode to fan only or heat
(3) Turning the unit off
(4) Control is rst plugged in or power is restored after failure
(5) Line power is restored from a brown out condition
Wait ICON (Hour Glass )
The wait icon will be turned on when the compressor is locked out and during demand for cooling or heat pump
compressor operation. The Wait ICON will be turned off when the condition clears.

CAPACITORS
ELECTRIC SHOCK HAZARD
WARNING
Turn off electric power before servicing.
Discharge capacitor with a 20,000 Ohm 2 Watt
resistor before handling.
Failure to do so may result in personal injury,
or death.
Many motor capacitors are internally fused. Shorting the
terminals will blow the fuse, ruining the capacitor. A 20,000
ohm 2 watt resistor can be used to discharge capacitors
safely. Remove wires from capacitor and place resistor
across terminals. When checking a dual capacitor with a
capacitor analyzer or ohmmeter, both sides must be tested.
Capacitor Check with Capacitor Analyzer
The capacitor analyzer will show whether the capacitor is
“open” or “shorted.” It will tell whether the capacitor is within
its micro farads rating and it will show whether the capacitor
is operating at the proper power-factor percentage. The
instrument will automatically discharge the capacitor when
the test switch is released.
Capacitor Connections
The starting winding of a motor can be damaged by a
shorted and grounded running capacitor. This damage
usually can be avoided by proper connection of the running
capacitor terminals.
From the supply line on a typical 230 volt circuit, a 115 volt
potential exists from the “R” terminal to ground through a
possible short in the capacitor. However, from the “S” or start
terminal, a much higher potential, possibly as high as 400
volts, exists because of the counter EMF generated in the
start winding. Therefore, the possibility of capacitor failure
is much greater when the identied terminal is connected
to the “S” or start terminal. The identied terminal should
always be connected to the supply line, or “R” terminal,
never to the “S” terminal.
When connected properly, a shorted or grounded running
capacitor will result in a direct short to ground from the “R”
terminal and will blow the line fuse. The motor protector will
protect the main winding from excessive temperature.
Dual Rated Run Capacitor Hook-up
BLOWER/FAN MOTOR - TEST
1. Determine that capacitor is serviceable.
2. Disconnect fan motor wires from fan speed switch or
system switch.
3. Apply “live test cord probes on black wire and common
terminal of capacitor. Motor should run at high speed.
4. Apply “live test cord probes on red wire and common
terminal of capacitor. Motor should run at low speed.
5. Apply “livetest cord probes on each of the remaining
wires from the speed switch or system switch to test
intermediate speeds. If the control is in the “MoneySaver”
mode and the thermostat calls for cooling, the fan will
start - then stop after approximately 2 minutes; then the
fan and compressor will start together approximately 2
minutes later.

HEATING ELEMENT
All heat pumps and electric heat models are equipped
with a heating element with the exception of model
YS10M10. The other “YS” and “ES” models are
equipped with a 3.3 KW element. The “YM” and “EM”
models are equipped with a 4.0 KW element. The “YL”
and “EL” models are equipped with a 5.2 KW element.
The heating element contains a fuse link and a heater
limit switch. The fuse link is in series with the power
supply and will open and interrupt the power when the
temperature reaches 199°F or a short circuit occurs in
the heating element. Once the fuse link separates, a
new fuse link must be installed.
NOTE: Always replace with the exact replacement.
The heater element has a high limit control. This
control is a bimetal thermostat mounted in the top of
the heating element.
Should the fan motor fail or lter become clogged,
the high limit control will open and interrupt power to
the heater before reaching an unsafe temperature
condition.
The control is designed to open at 110°F ±6°F. Test
continuity below 110°F or when it is cooled off.
HEATING ELEMENT (Heat Pump Models)
The heating element for the “Y” model is energized
by an outdoor thermistor via the electronic control
board. The outdoor defrost thermistor is adjusted at
a predetermined temperature of approximately 30
degrees Fahrenheit and sensed for two consecutive
minutes, to stop the compressor and turn on the
heating element.
Heating Element
Sample
TESTING THE HEATING ELEMENT
Testing of the elements can be made with an ohmmeter
across the terminals after the connecting wires
have been removed. A cold resistance reading of
approximately 14.5 ohms for the 3.3 KW heater, 11.9
ohms for the 4.0 KW heater and 9.15 ohms for the 5.2
KW heater should be registered.
DRAIN PAN VALVE
During the cooling mode of operation, condensate
which collects in the drain pan is picked up by the con-
denser fan blade and sprayed onto the condenser coil.
This assists in cooling the refrigerant plus evaporating
the water.
During the heating mode of operation, it is necessary
that water be removed to prevent it from freezing during
cold outside temperatures. This could cause the con-
denser fan blade to freeze in the accumulated water
and prevent it from turning.
To provide a means of draining this water, a bellows
type drain valve is installed over a drain opening in the
base pan.
This valve is temperature sensitive and will open when
the outside temperature reaches 40°F. The valve will
close gradually as the temperature rises above 40°F to
fully close at 60°F.

A good understanding of the basic operation of the
refrigeration system is essential for the service technician.
Without this understanding, accurate troubleshooting of
refrigeration system problems will be more difcult and time
consuming, if not (in some cases) entirely impossible. The
refrigeration system uses four basic principles (laws) in its
operation they are as follows:
1. “Heat always ows from a warmer body to a cooler body.”
2. “Heat must be added to or removed from a substance
before a change in state can occur”
3. “Flow is always from a higher pressure area to a lower
pressure area.”
4. “The temperature at which a liquid or gas changes state
is dependent upon the pressure.”
The refrigeration cycle begins at the compressor. Starting
the compressor creates a low pressure in the suction line
which draws refrigerant gas (vapor) into the compressor.
The compressor then “compresses” this refrigerant, raising
its pressure and its (heat intensity) temperature.
The refrigerant leaves the compressor through the discharge
Line as a hot High pressure gas (vapor). The refrigerant
enters the condenser coil where it gives up some of its
heat. The condenser fan moving air across the coil’s nned
surface facilitates the transfer of heat from the refrigerant to
the relatively cooler outdoor air.
When a sufcient quantity of heat has been removed from
the refrigerant gas (vapor), the refrigerant will “condense”
(i.e. change to a liquid). Once the refrigerant has been
condensed (changed) to a liquid it is cooled even further by
the air that continues to ow across the condenser coil.
The RAC design determines at exactly what point (in the
condenser) the change of state (i.e. gas to a liquid) takes
place. In all cases, however, the refrigerant must be
totally condensed (changed) to a Liquid before leaving the
condenser coil.
The refrigerant leaves the condenser Coil through the
liquid line as a warm high pressure liquid. It next will pass
through the refrigerant drier (if so equipped). It is the function
of the drier to trap any moisture present in the system,
contaminants, and large particulate matter.
The liquid refrigerant next enters the metering device. The
metering device is a capillary tube. The purpose of the
metering device is to “meter” (i.e. control or measure) the
quantity of refrigerant entering the evaporator coil.
In the case of the capillary tube this is accomplished (by
design) through size (and length) of device, and the pressure
difference present across the device.
Since the evaporator coil is under a lower pressure (due to
the suction created by the compressor) than the liquid line,
the liquid refrigerant leaves the metering device entering the
evaporator coil. As it enters the evaporator coil, the larger
area and lower pressure allows the refrigerant to expand
and lower its temperature (heat intensity). This expansion is
often referred to as “boiling”. Since the unit’s blower is moving
indoor air across the nned surface of the evaporator coil,
the expanding refrigerant absorbs some of that heat. This
results in a lowering of the indoor air temperature, hence the
“cooling” effect.
The expansion and absorbing of heat cause the liquid
refrigerant to evaporate (i.e. change to a gas). Once the
refrigerant has been evaporated (changed to a gas), it is
heated even further by the air that continues to ow across
the evaporator coil.
The particular system design determines at exactly what
point (in the evaporator) the change of state (i.e. liquid to a
gas) takes place. In all cases, however, the refrigerant must
be totally evaporated (changed) to a gas before leaving the
evaporator coil.
The low pressure (suction) created by the compressor
causes the refrigerant to leave the evaporator through the
suction line as a cool low pressure vapor. The refrigerant
then returns to the compressor, where the cycle is repeated.
REFRIGERATION SEQUENCE OF OPERATION

R-410A pressure is approximately 60% higher than R-22 pressure.
R-410A cylinders must not be allowed to exceed 125 F, they may leak or rupture.
R-410A must never be pressurized with a mixture of air, it may become
ammable.
Servicing equipment and components must be specically designed for use with R-410A and
dedicated to prevent contamination.
Manifold sets must be equipped with gauges capable of reading 750 psig (high side) and 200
psig (low side), with a 500-psig low-side retard.
Gauge hoses must have a minimum 750-psig service pressure rating
Recovery cylinders must have a minimum service pressure rating of 400 psig, (DOT 4BA400
and DOT BW400 approved cylinders).
POE (Polyol-Ester) lubricants must be used with R-410A equipment.
To prevent moisture absorption and lubricant contamination, do not leave the refrigeration
system open to the atmosphere longer than 1 hour.
Weigh-in the refrigerant charge into the high side of the system.
Introduce liquid refrigerant charge into the high side of the system.
For low side pressure charging of R-410A, use a charging adaptor.
Use Friedrich approved R-410A lter dryers only.
The following is a list of important considerations when working with R-410A equipment
R-410A SEALED SYSTEM REPAIR CONSIDERATIONS
Do not puncture, heat, expose to ame or incinerate.
Only certied refrigeration technicians should
service this equipment.
R410A systems operate at higher pressures than
R22 equipment. Appropriate safe service and
handling practicces must be used.
Only use gauge sets designed for use with R410A.
Do not use standard R22 gauge sets.
WARNING
Refrigeration system under high pressure

Proper refrigerant charge is essential to proper unit operation.
Operating a unit with an improper refrigerant charge will
result in reduced performance (capacity) and/or efciency.
Accordingly, the use of proper charging methods during
servicing will insure that the unit is functioning as designed
and that its compressor will not be damaged.
Too much refrigerant (overcharge) in the system is just as bad
(if not worse) than not enough refrigerant (undercharge). They
both can be the source of certain compressor failures if they
remain uncorrected for any period of time. Quite often, other
problems (such as low air ow across evaporator, etc.) are
misdiagnosed as refrigerant charge problems. The refrigerant
circuit diagnosis chart will assist you in properly diagnosing
these systems.
An overcharged unit will at times return liquid refrigerant
(slugging) back to the suction side of the compressor eventually
causing a mechanical failure within the compressor. This
mechanical failure can manifest itself as valve failure, bearing
failure, and/or other mechanical failure. The specic type of
failure will be inuenced by the amount of liquid being returned,
and the length of time the slugging continues.
Not enough refrigerant (undercharge) on the other hand,
will cause the temperature of the suction gas to increase to
the point where it does not provide sufcient cooling for the
compressor motor. When this occurs, the motor winding
temperature will increase causing the motor to overheat
and possibly cycle open the compressor overload protector.
Continued overheating of the motor windings and/or cycling
of the overload will eventually lead to compressor motor or
overload failure.
Sealed Refrigeration System contains refrigerant
and oil under high pressure.
Proper safety procedures must be followed,
and proper protective clothing must be worn
when working with refrigerants.
Failure to follow these procedures could
result in serious injury or death.

Method Of Charging / Repairs
The acceptable method for charging the sealed system is the
Weighed in Charge Method. The weighed in charge method is
applicable to all units. It is the preferred method to use, as it is
the most accurate.
The weighed in method should always be used whenever
a charge is removed from a unit such as for a leak repair,
compressor replacement, or when there is no refrigerant
charge left in the unit. To charge by this method, requires the
following steps:
1. Install a piercing valve to remove refrigerant from the
sealedsystem. (Piercing valve must be removed from the
system before recharging.)
2. Recover Refrigerant in accordance with EPA regulations.
39
Undercharged Refrigerant Systems
An undercharged system will result in poor performance
(low pressures, etc.) in both the heating and cooling cycle.
Whenever you service a unit with an undercharge of
refrigerant, always suspect a leak. The leak must be
repaired before charging the unit.
To check for an undercharged system, turn the unit on,
allow the compressor to run long enough to establish
working pressures in the system (15 to 20 minutes).
During the cooling cycle you can listen carefully at the exit
of the metering device into the evaporator; an intermittent
hissing and gurgling sound indicates a low refrigerant
charge. Intermittent frosting and thawing of the evaporator
is another indication of a low charge, however, frosting
and thawing can also be caused by insufcient air over
the evaporator.
Checks for an undercharged system can be made at
the compressor. If the compressor seems quieter than
normal, it is an indication of a low refrigerant charge.
Overcharged Refrigerant Systems
A check of the amperage drawn by the compressor
motor should show a lower reading. (Check the Unit
Specication.) After the unit has run 10 to 15 minutes,
check the gauge pressures. Gauges connected to system
with an undercharge will have low head pressures and
substantially low suction pressures.
of the evaporator will not be encountered because the
refrigerant will boil later if at all. Gauges connected to
system will usually have higher head pressure (depending
upon amount of over charge). Suction pressure should be
slightly higher.
Compressor amps will be near normal or higher.
Noncondensables can also cause these symptoms.
To conrm, remove some of the charge, if conditions
improve, system may be overcharged. If conditions don’t
improve, Noncondensables are indicated.
Whenever an overcharged system is indicated, always
make sure that the problem is not caused by air ow
problems. Improper air ow over the evaporator coil may
indicate some of the same symptoms as an over charged
system.
An overcharge can cause the compressor to fail, since it
would be “slugged” with liquid refrigerant.
The charge for any system is critical. When the compressor
is noisy, suspect an overcharge, when you are sure that
the air quantity over the evaporator coil is correct. Icing

40
Restricted Refrigerant System
Troubleshooting a restricted refrigerant system can be
difcult. The following procedures are the more common
problems and solutions to these problems. There are two
types of refrigerant restrictions: Partial restrictions and
complete restrictions.
A partial restriction allows some of the refrigerant to
circulate through the system.
With a complete restriction there is no circulation of
refrigerant in the system.
Restricted refrigerant systems display the same symptoms
as a “low-charge condition.”
When the unit is shut off, the gauges may equalize very
slowly.
Gauges connected to a completely restricted system
will run in a deep vacuum. When the unit is shut off, the
gauges will not equalize at all.
A quick check for either condition begins at the evaporator.
With a partial restriction, there may be gurgling sounds
at the metering device entrance to the evaporator. The
evaporator in a partial restriction could be partially frosted
or have an ice ball close to the entrance of the metering
device. Frost may continue on the suction line back to the
compressor.
Often a partial restriction of any type can be found by feel,
as there is a temperature difference from one side of the
restriction to the other.
With a complete restriction, there will be no sound at the
metering device entrance. An amperage check of the
compressor with a partial restriction may show normal
current when compared to the unit speci cation. With a
complete restriction the current drawn may be considerably
less than normal, as the compressor is running in a deep
vacuum (no load.) Much of the area of the condenser will
be relatively cool since most or all of the liquid refrigerant
will be stored there.
The following conditions are based primarily on a system
in the cooling mode.
41
METERING DEVICE
Capillary Tube Systems
All units are equipped with capillary tube metering devices.
Checking for restricted capillary tubes.
1. Connect pressure gauges to unit.
2. Start the unit in the cooling mode. If after a few minutes
of operation the pressures are normal, the check valve
and the cooling capillary are not restricted.
3. Switch the unit to the heating mode and observe the
gauge readings after a few minutes running time. If
the system pressure is lower than normal, the heating
capillary is restricted.
4. If the operating pressures are lower than normal in both
the heating and cooling mode, the cooling capillary is
restricted.
Proper safety procedures must be followed,
and proper protective clothing must be worn
when working with a torch.
Failure to follow these procedures could
result in moderate or serious injury.
WARNING
BURN HAZARD
HERMETIC COMPONENTS CHECK
One-way Check Valve
(Heat Pump Models)
CHECK VALVE
A unique two-way check valve is used on the reverse cycle
heat pumps. It is pressure operated and used to direct the
ow of refrigerant through a single lter drier and to the
proper capillary tube during either the heating or cooling
cycle.
NOTE: The slide (check) inside the valve is made of teon.
Should it become necessary to replace the check valve,
place a wet cloth around the valve to prevent overheating
during the brazing operation.
CHECK VALVE OPERATION
In the cooling mode of operation, high pressure liquid enters
the check valve forcing the slide to close the opposite port
(liquid line) to the indoor coil. Refer to refrigerant ow chart.
This directs the refrigerant through the lter drier and cooling
capillary tube to the indoor coil.
In the heating mode of operation, high pressure refrigerant
enters the check valve from the opposite direction, closing
the port (liquid line) to the outdoor coil. The ow path of
the refrigerant is then through the lter drier and heating
capillary to the outdoor coil.
Failure of the slide in the check valve to seat properly in
either mode of operation will cause ooding of the cooling
coil. This is due to the refrigerant bypassing the heating or
cooling capillary tube and entering the liquid line.
COOLING MODE
In the cooling mode of operation, liquid refrigerant from
condenser (liquid line) enters the cooling check valve
forcing the heating check valve shut. The liquid refrigerant
is directed into the liquid dryer after which the refrigerant
is metered through cooling capillary tubes to evaporator.
(Note: liquid refrigerant will also be directed through the
heating capillary tubes in a continuous loop during the
cooling mode).
HEATING MODE
In the heating mode of operation, liquid refrigerant from
the indoor coil enters the heating check valve forcing the
cooling check valve shut. The liquid refrigerant is directed
into the liquid dryer after which the refrigerant is metered
through the heating capillary tubes to outdoor coils. (Note:
liquid refrigerant will also be directed through the cooling
capillary tubes in a continuous loop during the heating
mode).
CUT/SEVER HAZARD
WARNING
Be careful with the sharp edges and corners.
Wear protective clothing and gloves, etc.
Failure to do so could result in serious injury.
42
NOTE: System operating pressures must be near
normal before valve can shift.
REVERSING VALVE DESCRIPTION/OPERATION
The Reversing Valve controls the direction of refrigerant
ow to the indoor and outdoor coils. It consists of a
pressure-operated, main valve and a pilot valve actuated
by a solenoid plunger. The solenoid is energized during the
heating cycle only. The reversing valves used in the RAC
system is a 2-position, 4-way valve.
The single tube on one side of the main valve body is the
high-pressure inlet to the valve from the compressor. The
center tube on the opposite side is connected to the low
pressure (suction) side of the system. The other two are
connected to the indoor and outdoor coils. Small capillary
tubes connect each end of the main valve cylinder to the
“A” and “B” ports of the pilot valve. A third capillary is a common
return line from these ports to the suction tube on the main
valve body. Four-way reversing valves also have a capillary
tube from the compressor discharge tube to the pilot valve.
The piston assembly in the main valve can only be shifted
by the pressure differential between the high and low sides
of the system. The pilot section of the valve opens and
closes ports for the small capillary tubes to the main valve
to cause it to shift.
ELECTRIC SHOCK HAZARD
WARNING
Disconnect power to the unit before servicing.
Failure to follow this warning could result in
serious injury or death.
43
Reversing Valve in Heating Mode
TESTING THE REVERSING VALVE
SOLENOID COIL
The solenoid coil is an electromagnetic type coil mounted
on the reversing valve and is energized during the
operation of the compressor in the heating cycle.
1. Turn off high voltage electrical power to unit.
2. Unplug line voltage lead from reversing valve coil.
3. Check for electrical continuity through the coil. If you
do not have continuity replace the coil.
4. Check from each lead of coil to the copper liquid line
as it leaves the unit or the ground lug. There should
be no continuity between either of the coil leads
and ground; if there is, coil is grounded and must be
replaced.
5. If coil tests okay, reconnect the electrical leads.
6. Make sure coil has been assembled correctly.
NOTE: Do not start unit with solenoid coil removed from
valve, or do not remove coil after unit is in operation. This
will cause the coil to burn out.
CHECKING THE REVERSING VALVE
NOTE: You must have normal operating pressures before
the reversing valve can shift.
Check the operation of the valve by starting the system
and switching the operation from “Cooling” to “Heating”
and then back to “Cooling”. Do not hammer on valve.
Occasionally, the reversing valve may stick in the heating
or cooling position or in the mid-position.
When sluggish or 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.
ELECTRIC SHOCK HAZARD
WARNING
Unplug and/or disconnect all electrical power
to the unit before performing inspections,
maintenances or service.
Failure to do so could result in electric shock,
serious injury or death.
Sealed Refrigeration System contains refrigerant
and oil under high pressure.
Proper safety procedures must be followed,
and proper protective clothing must be worn

WARNING
HIGH PRESSURE HAZARD
Should the valve fail to shift from coooling to heating,
block the air ow through the outdoor coil and allow the
discharge pressure to build in the system. Then switch
the system from heating to cooling.
If the valve is stuck in the heating position, block the air
ow through the indoor coil and allow discharge pressure
to build in the system. Then switch the system from
heating to cooling.
Should the valve fail to shift in either position after
increasing the discharge pressure, replace the valve.
Dented or damaged valve body or capillary tubes can
prevent the main slide in the valve body from shifting.
If you determing this is the problem, replace the reversing
valve.
After all of the previous inspections and checks have
been made and determined correct, then perform the
“Touch Test” on the reversing valve.
44
8. Pressurize sealed system with a combination of R-410A
and nitrogen and check for leaks, using a suitable leak
detector. Recover refrigerant per EPA guidelines.
9. Once the sealed system is leak free, install solenoid coil
on new valve and charge the sealed system by weighing
in the proper amount and type of refrigerant as shown
on rating plate. Crimp the process tubes and solder the
ends shut. Do not leave Schrader or piercing valves in
the sealed system.
NOTE: 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
conduction of heat to the valve body when brazing the line
connection.
6. Protect new valve body from heat while brazing with plastic
heat sink (Thermo Trap) or wrap valve body with wet rag.
7. Fit all lines into new valve and braze lines into new
valve.
Procedure For Changing Reversing Valve
1. Install Process Tubes. Recover refrigerant from sealed
system. PROPER HANDLING OF RECOVERED
REFRIGERANT ACCORDING TO EPA REGULATIONS
IS REQUIRED.
2. Remove solenoid coil from reversing valve. If coil is to
be reused, protect from heat while changing valve.
3. Unbraze all lines from reversing valve.
4. Clean all excess braze from all tubing so that they will
slip into ttings on new valve.
5. Remove solenoid coil from new valve.
The use of a torch requires extreme care and proper
judgment. Follow all safety recommended precautions and
protect surrounding areas with re proof materials. Have
a re extinguisher readily available. Failure to follow this
notice could result in moderate to serious property damage.
NOTICE
FIRE HAZARD
Touch Test in Heating/Cooling Cycle
The only definite indications that the slide is in the mid-
position is if all three tubes on the suction side of the valve
are hot after a few minutes of running time.
NOTE: A condition other than those illustrated above, and
on Page 44, indicate that the reversing valve is not shifting
properly. Both tubes shown as hot or cool must be the same
corresponding temperature.
Certain unit components operate at
temperatures hot enough to cause burns.
Proper safety procedures must be followed,
and proper protective clothing must be
worn.
Failure to follow these procedures could

Locked Rotor Voltage (L.R.V.) Test
Locked rotor voltage (L.R.V.) is the actual voltage available
at the compressor under a stalled condition.
Single Phase Connections
Disconnect power from unit. Using a voltmeter, attach one
lead of the meter to the run “R” terminal on the compressor
and the other lead to the common “C” terminal of the com-
pressor. Restore power to unit.
Determine L.R.V.
Start the compressor with the volt meter attached; then stop
the unit. Attempt to restart the compressor within a couple
of seconds and immediately read the voltage on the meter.
The compressor under these conditions will not start and will
usually kick out on overload within a few seconds since the
pressures in the system will not have had time to equalize.
Voltage should be at or above minimum voltage of 197 VAC,
as specied on the rating plate. If less than minimum, check
for cause of inadequate power supply; i.e., incorrect wire
size, loose electrical connections, etc.
COMPRESSOR CHECKS
ELECTRIC SHOCK HAZARD
WARNING
Turn off electric power before service or
installation. Extreme care must be used, if it
becomes necessary to work on equipment with
power applied.
Failure to do so could result in serious injury or
death.
Heat generated within the compressor shell, usually due
to recycling of the motor, is slow to dissipate. It may take
anywhere from a few minutes to several hours for the
overload to reset.
Checking the Overloads
External Overloads
With power off, remove the leads from compressor
terminals. If the compressor is hot, allow the overload
to cool before starting check. Using an ohmmeter, test
continuity across the terminals of the external overload.
If you do not have continuity; this indicates that the
overload is open and must be replaced.
Interrnal Overloads
Some model compressors are equipped with an internal
overload. The overload is embedded in the motor
windings to sense the winding temperature and/or current
draw. The overload is connected in series with the
common motor terminal.
Should the internal temperature and/or current draw
become excessive, the contacts in the overload will
open, turning off the compressor. The overload will
automatically reset, but may require several hours before
the heat is dissipated.
Checking the Internal Overload
1. With no power to unit, remove the leads from the
compressor terminals.
2. Using an ohmmeter, test continuity between terminals
C-S and C-R. If no continuity, the compressor overload is
open and the compressor must be replaced.
Amperage (L.R.A.) Test
The running amperage of the compressor is the most
important of these readings. A running amperage higher
than that indicated in the performance data indicates that a
problem exists mechanically or electrically.
Single Phase Running and L.R.A. Test
NOTE: Consult the specication and performance section
for running amperage. The L.R.A. can also be found on the
rating plate.
Select the proper amperage scale and clamp the meter
probe around the wire to the “C” terminal of the compressor.
Turn on the unit and read the running amperage on the
meter. If the compressor does not start, the reading will
indicate the locked rotor amperage (L.R.A.).
Overloads
The compressor is equipped with either an external or
internal overload which senses both motor amperage
and winding temperature. High motor temperature or
amperage heats the overload causing it to open, breaking
the common circuit within the compressor.
Certain unit components operate at
temperatures hot enough to cause burns.
Proper safety procedures must be followed,
and proper protective clothing must be
worn.
Failure to follow this warning could result
in moderate to serious injury.

GROUND TEST
Use an ohmmeter set on its highest scale. Touch one
lead to the compressor body (clean point of contact as
a good connection is a must) and the other probe in turn
to each compressor terminal. If a reading is obtained the
compressor is grounded and must be replaced.
Check the complete electrical system to the compressor
and compressor internal electrical system, check to be
certain that compressor is not out on internal overload.
Complete evaluation of the system must be made
whenever you suspect the compressor is defective. If
the compressor has been operating for sometime, a
careful examination must be made to determine why the
compressor failed.
Many compressor failures are caused by the following
conditions:
1. Improper air flow over the evaporator.
2. Overcharged refrigerant system causing liquid to be
returned to the compressor.
3. Restricted refrigerant system.
4. Lack of lubrication.
5. Liquid refrigerant returning to compressor causing oil
to be washed out of bearings.
6. Noncondensables such as air and moisture in
the system. Moisture is extremely destructive to a
refrigerant system.
7. Capacitor (see page 34).
CHECKING COMPRESSOR EFFICIENCY
The reason for compressor inefficiency is normally due
to broken or damaged suction and/or discharge valves,
reducing the ability of the compressor to pump refrigerant
gas.
This condition can be checked as follows:
1. Install a piercing valve on the suction and discharge or
liquid process tube.
2. Attach gauges to the high and low sides of the system.
3. Start the system and run a “cooling or heating perfor
-
mance test.” If test shows:
A. Below normal high side pressure
B. Above normal low side pressure
C. Low temperature difference across coil
The compressor valves are faulty - replace the
compressor.

Recommended procedure for compressor
replacement
1. Be certain to perform all necessary electrical and
refrigeration tests to be sure the compressor is
actually defective before replacing.
2. Recover all refrigerant from the system though
the process tubes. PROPER HANDLING OF
RECOVERED REFRIGERANT ACCORDING TO
EPA REGULATIONS IS REQUIRED. Do not use
gauge manifold for this purpose if there has been
a burnout. You will contaminate your manifold and
hoses. Use a Schrader valve adapter and copper
tubing for burnout failures.
3. After all refrigerant has been recovered, disconnect
suction and discharge lines from the compressor and
remove compressor. Be certain to have both suction
and discharge process tubes open to atmosphere.
4. Carefully pour a small amount of oil from the suction
stub of the defective compressor into a clean container.
9. Evacuate the system with a good vacuum pump capable
of a nal vacuum of 200 microns or less. The system
should be evacuated through both liquid line and suction
line gauge ports. While the unit is being evacuated, seal
all openings on the defective compressor. Compressor
manufacturers will void warranties on units received not
properly sealed. Do not distort the manufacturers tube
connections.
10. Recharge the system with the correct amount of
refrigerant. The proper refrigerant charge will be
found on the unit rating plate. The use of an accurate
measuring device, such as a charging cylinder,
electronic scales or similar device is necessary.
COMPRESSOR REPLACEMENT
5. Using an acid test kit (one shot or conventional kit), test
the oil for acid content according to the instructions
with the kit.
6. If any evidence of a burnout is found, no matter how
slight, the system will need to be cleaned up following
proper procedures.
7. Install the replacement compressor.
8. Pressurize with a combination of R-410A and nitrogen
and leak test all connections with an electronic or
Halide leak detector. Recover refrigerant and repair
any leaks found.
Repeat Step 8 to insure no more leaks are present.
Unplug and/or disconnect all electrical power

SLEEVE / DRAIN
Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and
debris. Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and
ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as
needed.
DECORATIVE FRONT COVER
Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow it to dry
thoroughly before reinstalling it in the chassis.
The decorative front and the cabinet can be cleaned with warm water and a mild liquid detergent. Do NOT use
solvents or hydrocarbon based cleaners such as acetone, naphtha, gasoline, benzene, etc.
Use a damp (not wet) cloth when cleaning the control area to prevent water from entering the unit, and possibly
damaging the electronic control.
CLEARANCES
Inspect the surrounding area (inside and outside) to ensure that the unit’s clearances have not been compromised or
altered.
ROUTINE MAINTENANCE (Continued)
Do not drill holes in the bottom of the drain pan or the
underside of the unit. Not following this notice could
result in damage to the unit or condensate water leaking
inappropriately which could cause water damage to

u Ensure that the circuit breaker(s) or fuse(s) and supply circuit wire
size have been sized correctly. If the unit was supplied with a power
supply cord, insure that it is stored properly.
u Ensure that the entire installation is in compliance with all applicable
national and local codes and ordinances having jurisdiction.
u Secure components and accessories, such as a decorative front
cover.
u Start the unit and check for proper operation of all components in
each mode of operation.
u Instruct the owner or operator of the units operation, and the
manufacturer's Routine Maintenance.
NOTE: A log for recording the dates of maintenance and/or service is
recommended.
u Present the owner or operator of the equipment with the name,
address and telephone number of the Authorized Friedrich Warranty
Service Company in the area for future reference if necessary.
NOTE: This is a warm weather appliance
The air conditioner is designed to cool in warm weather when the outside
temperature is above 60° F (15.6° C) and below 115° F (46.1° C), so it won't
cool a room if it is already cool outside. If you want to cool a room in the
spring or fall, select the FAN ONLY mode and set the Fresh Air/Exhaust
air control to Fresh Air. This will bring in a supply of cooler outside air.
Condensation is normal
Air conditioners actually pump the heat and humidity from your room to the
outside. Humidity becomes water, and your air conditioner will use most
of the water to keep the outside coil cool. If there is excessive humidity,
there may be excess water that will drip outside. This is normal operation.
Frosting
This usually occurs because of insufcient airow across the coils, a dirty
lter, cool damp weather, or all of these. Set the SYSTEM mode to FAN
ONLY and the frost will disappear. Setting the thermostat a little warmer
will probably prevent the frosting from recurring.
Noises
All air conditioners make some noise. Friedrich units are designed to
operate as quietly as possible. An air conditioner mounted in a wall is
quieter than one mounted in a window. It is important to ensure that the
chassis seal gasket (Item 14) is properly installed (refer to installation
instructions).
After Maintenance/Repair
Start-up Checklist and Notes
u Inspect and ensure that all components and accessories have been
installed properly and that they have not been damaged during the
installation progress.
u Check the condensate water drain(s) to ensure that they are adequate
for the removal of condensate water, and that they meet the approval
of the end user.
u Ensure that all installation instructions concerning clearances around
the unit have been adhered to. Check to ensure that the unit air lter,
indoor coil, and outdoor coil are free from any obstructions.
ROUTINE MAINTENANCE (Continued)
Heat pumps operate differently
If your unit is a "Y", or heat pump model, there are some things that you
will want to be aware of. Some functions of a heat pump differ from your
unit when it is used for heating:
1. It is normal for ice to form on the outdoor coil of the heat pump.
Moisture in the outside air, passing over the coil when very cold,
will form ice.
2. If the outdoor temperature drops below 37° F (3° C), your heat
pump will automatically turn on the electric resistance heat. When
the temperature rises to 40° F (4° C), the compressor will resume
the heat pump operation. If your unit is a 115 volt model (YS10),
it is designed for use in warmer climates and does not have an
electrical heat feature, and will not provide adequate heat below
37° F (2.8° C).

Problem Possible Cause Possible Solution
Unit Does Not Cool/Heat
On And Off Too Frequently
(continued).
The outside temperature is below
60° F (16° C).
Do not try to operate your air conditioner in the
cooling mode when the outside temperature
is below 60° F (16° C). The unit will not cool
properly, and the unit may be damaged.
The digital control is set to fan
cycling mode.
Since the fan does not circulate the room
air continuously at this setting, the room air
does not mix as well and hot (or cold) spots
may result. Using the continuous fan setting
is recommended to obtain optimum comfort
levels.
cooling capacity to match the heat
gain of the room.
Check the cooling capacity of your unit to
ensure it is properly sized for the room in which
it is installed. Room air conditioners are not
designed to cool multiple rooms.
heating capacity to match the heat
loss of the room.
Check the heating capacity of your unit. Air
conditioners are sized to meet the cooling load,
and heater size is then selected to meet the
heating load. In extreme northern climates,
room air conditioners may not be able to be
used as a primary source of heat.
Unit Runs Too Much.
This may be due to an excessive
heat load in the room.
If there are heat producing appliances in use
in the room, or if the room is heavily occupied,
the unit will need to run longer to remove the
additional heat.
It may also be due to an improperly
sized unit.
Be sure to use exhaust vent fans while cooking
or bathing and, if possible, try not to use heat
producing appliances during the hottest part of
the day.
This may be normal for higher
your new air conditioner may result in the
unit running longer than you feel it should.
This may be more apparent, if it replaced an
compared to older models.
You may notice that the discharge
air temperature of your new air
conditioner may not seem as cold
as you may be accustomed to from
older units. This does not, however,
indicate a reduction in the cooling
capacity of the unit.
