REMOTE THERMOSTAT AND LOW VOLTAGE
CONTROL CONNECTIONS
Room Thermostats
Room thermostats are available from several different
manufacturers in a wide variety of styles. They range from
the very simple Bimetallic type to the complex electronic set-
back type. In all cases, no matter how simple or complex,
they are simply a switch (or series of switches) designed to
turn equipment (or components) “ON” or “OFF” at the desired
conditions.
An improperly operating, or poorly located room thermostat
can be the source of perceived equipment problems. A careful
check of the thermostat and wiring must be made then to
insure that it is not the source of problems.
Remote Thermostat
All Friedrich PD model PTAC units are factory congured to
be controlled by either the chassis mounted Smart Center
or a 24V single stage remote wall mounted thermostat. The
thermostat may be auto or manual changeover as long as the
control conguration matches that of the PTAC unit.
For Heat Pump equipped units: A single stage, heat/cool
thermostat with a terminal for a reversing valve operation is
required. Terminal “B” should be continuously energized in the
heat mode and terminal “G” should be energized whenever
there is a call for heating or cooling. Typically, a single stage,
heat/cool thermostat designed for use with electric heat
systems will meet the above requirements.
To control the unit with a wall mounted thermostat follow
the steps below:
1) With the front cover removed locate the low voltage
terminal strip at the lower portion of the Smart Center.
2) Remove the jumper between the ‘GL’ and GH’
terminals.
3) The control is now congured for control by a wall
thermostat. The Smart Center will no longer control the
unit.
4) If desired the accessory escutcheon kit (PDXRT) is to
be used, install it over the existing control panel
Note: To revert back to the Smart Center control of the unit
replace the jumper wire between the ‘GL’ and ‘GH’ terminals
that was removed in step 1.
Remote Thermostat Control
Heat Pump with Electric Heat Operation
When there is a call for heat from the wall thermostat the
control board will receive signals on terminals W, B, GL or
GH. During compressor lock-out time, the electric heat will
turn on rst. When the compressor lock-out time is up, the
compressor will turn on. If the outdoor coil temperature sensor
drops to 30° F or less for 2 consecutive minutes then the unit
will switch to electric heat.
Location
The thermostat should not be mounted where it may be
affected by drafts, discharge air from registers (hot or
cold), or heat radiated from the sun or appliances.
The thermostat should be located about 5 Ft. above the
oor in an area of average temperature, with good air
circulation. Close proximity to the return air grille is the
best choice.
Mercury bulb type thermostats MUST be level to control
temperature accurately to the desired set-point. Electronic
digital type thermostats SHOULD be level for aesthetics.

NOTE: It is the installer’s responsibility to ensure that all
control wiring connectiions are made in accordance with
the Friedrich installation instructions. Improper connection
of the thermostat control wiring and/or tampering with the
unit’s internal wiring can void the equipment warranty.
Questions concerning proper connections to the unit
should be directed to the factory: 210-357-4400.
Thereafter, the unit will switch back to heat pump heat if the
outdoor coil temperature sensor rises to 45’ F or greater.

FRIEDRICH DIGITAL CONTROL FEATURES
The new Friedrich digital PTAC has state of the art features to improve guest comfort, indoor air quality and conserve
energy. Through the use of specically designed control software for the PTAC industry Friedrich has accomplished
what other Manufacturer’s have only attempted – a quiet, dependable, affordable and easy to use PTAC.
Below is a list of standard features on every Friedrich PTAC and their benet to the owner.
Digital Temperature
Readout
By digitally monitoring desired room temperature the room is controlled more precisely than conventional
systems. The large, easy to read LED display can show either set-point or actual room temperature as
selected by owner.
One-Touch
Operation
When the unit is powered off the unit can be returned directly to heating or cooling mode by pressing the
‘Heat’ or ‘Cool’ buttons without the confusing power up sequence of some controls. One-touch control
takes guess-work out of unit control delivering a more enjoyable experience and eliminating front-desk
calls.
Individual Mode and
Fan Control Buttons
By having separate control buttons and indicators for both fan and mode settings the Friedrich digital con-
trol eliminates the confusion of previous digital PTACs. The accurate temperature setting provides greater
guest comfort than other systems.
Quiet Start/Stop
Fan Delay
The fan start and stop delays prevent abrupt changes in room acoustics due to the compressor energizing
or stopping immediately. Upon call for cooling or heating the unit fan will run for ve seconds prior to en-
ergizing the compressor. Also, the fan off delay allows for “free cooling” by utilizing the already cool indoor
coil to its maximum capacity by running for 30 seconds after the compressor.
Remote Thermostat
Operation
Some applications require the use of a wall mounted thermostat. All new Friedrich PTACs may be switched
from unit control to remote thermostat control easily without the need to order a special model or acces-
sory kit.
Wireless Remote
Control Ready
Guests can adjust the temperature and mode of the unit through the use of an optional hand held wireless
remote, improving guest comfort and relaxation.
Internal Diagnostic
Program
The new Friedrich digital PTAC features a self diagnostic program that can alert maintenance to compo-
nent failures or operating problems. The internal diagnostic program saves properties valuable time when
diagnosing running problems.
Service Error Code
Storage
The self diagnosis program will also store error codes in memory if certain conditions occur and correct
themselves such as extreme high or low operating conditions or activation of the room freeze protection
feature. Storing error codes can help properties determine if the unit faced obscure conditions or if an error
occurred and corrected itself.
Constant Comfort
Room Monitoring
The on-board processor monitors time between demand cycles (heat or cool) and will cycle the fan every
9 minutes to sample the room condition and determine if the desired conditions are met. This allows the
room to have similar bene ts to a remote mounted stat without the complication or cost of a wall mounted
thermostat.
Electronic
Temperature
Limiting
By limiting the operating range the property can save energy by eliminating “max cool” or “max heat” situ-
ations common with older uncontrolled systems. The new electronic control allows owners to set operating
ranges for both heating and cooling independently of one another.
Room Freeze
Protection
When the PTAC senses that the indoor room temperature has fallen to 40 F the unit will cycle on high fan °
and the electric strip heat to raise the room temperature to 46 F then cycle off again. This feature works °
regardless of the mode selected and can be turned off. The control will also store the Room Freeze cycle
in the service code memory for retrieval at a later date. This feature ensures that unoccupied rooms do not
reach freezing levels where damage can occur to plumbing and xtures.
Random
Compressor Restart
Multiple compressors starting at once can often cause electrical overloads and premature unit failure.
The random restart delay eliminates multiple units from starting at once following a power outage or initial
power up. The compressor delay will range from 180 to 240 seconds.
Digital Defrost
Thermostat
The new Friedrich PTAC uses a digital thermostat to accurately monitor the outdoor coil conditions to allow
the heat pump to run whenever conditions are correct. Running the PTAC in heat pump mode save energy
and reduces operating costs. The digital thermostat allows maximization of heat pump run time.
11
FRIEDRICH DIGITAL CONTROL FEATURES CONTINUED
Instant Heat
Heat Pump Mode
Heat pump models will automatically run the electric heater to quickly bring the room up to temperature
when initially energized, then return to heat pump mode. This ensures that the room is brought up to
temperature quickly without the usual delay associated with heat pump units.
Even Heat Monitoring
The digital control monitors indoor conditions to ensure that the room temperature is within ve degrees
of the setpoint. If necessary the unit will cycle the electric heat to maintain the temperature. This feature
ensures guest comfort by delivering the heating benets of an electric heater while maintaining the
efciency benets of a heat pump.
Fan Cycle Control
The owner may choose between fan cycling or fan continuous mode based on property preference. (Note:
Even heat monitoring and quiet start/stop fan delay only operate in fan cycle mode). Fan continuous
mode is used to keep constant airow circulation in the room during all times the unit is ‘ON’. Fan cycle
will conserve energy by only operating the fan while the compressor or electric heater is operating.
Emergency Heat
Override
In the event of a compressor failure in heat pump mode the compressor may be locked out to provide
heat through the resistance heater. This feature ensures that even in the unlikely event of a compressor
failure the room temperature can be maintained until the compressor can be serviced.
Desk Control Ready
All Friedrich digital PTACs have low voltage terminals ready to connect a desk control energy management
system. Controlling the unit from a remote location like the front desk can reduce energy usage and
requires no additional accessories at the PTAC.
Indoor Coil Frost
Sensor
The frost sensor protects the compressor from damage in the event that air ow is reduced or low
outdoor temperatures cause the indoor coil to freeze. When the indoor coil reaches 30 °F the compressor
is diabled and the fan continues to operate based on demand. Once the coil temperature returns to 45 °F
the compressor returns to operation.
Ultra-Quiet Air System The new Friedrich PD series units feature a indoor fan system design that reduces sound levels without
lowering airow and preventing proper air circulation.
High Efciency The Friedrich PTAC benets quality components and extensive development to ensure a quiet, efcient
and dependable unit.
Single Motor Friedrich’s single-motor design allows for enhanced outdoor airow and simplies the unit design without
the need for redundant components.
Rotary Compressor High efciency rotary compressors are used on all Friedrich PTACs to maximize durability and
efciency.
Auxiliary Fan Ready
The Friedrich PTAC features a 24V AC terminal for connection to an auxiliary fan that may be used to
transfer air to adjoining rooms. Auxiliary fans can provide conditioning to multiple rooms without the
requirement of multiple PTAC units.
Aluminum Endplates
All Friedrich PTACs are built with .04” endplates made from aluminum as opposed to steel. The endplates
are typically the most susceptible area for corrosion and aluminum is far more resistant to corrosion than
even coated steel.
Seacoast Protection
Optional Seacoast protection is available to protect the outdoor coil from harsh environments. The
Friedrich Seacoast process includes dipping the entire outdoor coil in a 7-step coating process that
provides superior protection to only coating the ns of the coil.
Top Mounted Anti-
microbial Air Filters
All Friedrich PTAC return air lters feature an anti-microbial element that has proven to prevent mold
and bacterial growth in laboratory testing. PDXFT replacement lter kits feature the same anti-microbial
agent. All lters are washable and reusable and are easily accessed from the top of the unit without the
removal of the front cover.
Filtered Fresh Air
Intake
Friedrich PTAC units are capable of introducing up to 70 CFM of outside air into the conditioned space.
The outdoor air passes through a washable mesh lter to prevent debris from entering the airstream.

Digital Control Panel
DIGITAL CONTROL OPERATION
Temperature Display
The Friedrich digital PTAC is shipped from the factory
to display the “Set Point” (desired room temperature) on the
LED readout.
The unit can be congured to display the room temperature
by simultaneously pressing the ‘Cool’ ‘High Fan’ and buttons
for three seconds. The display will show an ‘ ’ for one second R
to acknowledge the change. The unit will then display the “Set
Point” whenever the Temperature Up or Temperature
Down buttons are pressed, then switch back to display
actual room temperature.
To revert back to the factory setting displaying the “Set Point”
only, press the ‘ ’ and ‘ ’ buttons simultaneously Cool High Fan
for three seconds. The unit will display an ‘ ’ for one second S
to acknowledge the change.
°F vs. °C Display
Cooling Mode
Pressing the ‘Cool’ button while the unit is in any mode,
including off, will put the unit into cooling mode. Adjust the
temperature readout to the desired room temperature and
the unit will cycle the compressor on and off to maintain a
comfortable room. The compressor will come on anytime that
the room temperature is 1.8 F above the desired temperature. °
The fan operation is dependent on the fan mode selected,
either continuous or cycling.
Heating Mode
Pressing the ‘Heat’ button while the unit is in any mode,
including off, will put the unit into heating mode.
Heat Pump Models (PDH)
When the button is pressed initially the unit will energize ‘Heat’
the electric resistance heat to quickly bring the room to the
set temperature. When the desired room temperature falls
1.8 F below the desired set temperature the unit will cycle °
the compressor on and operate as a heat pump to maintain
the room temperature while running more efciently than
resistance heat only models. If the room temperature should
fall more than 5 F from the set temperature the unit will run °
the resistance heater. The fan operation is dependent on the
fan mode selected, either continuous or cycling. Dip switch 5
controls the fan mode, see “Dip Switch” setting elsewhere in
this manual.
When the outdoor coil temperature falls below 30 F for more °
than 2 minutes the unit will operate the resistance heaters and
not the compressor. When the outdoor coil temperature reaches
45 F the compressor will be allowed to operate again.°
Heat/Cool Models (PDE)
After pressing the button, adjust the temperature ‘Heat’
readout to the desired room temperature and the unit will cycle
the resistance heat on and off to maintain a comfortable room.
The heater will come on anytime that the room temperature
is 1.8 F below the desired temperature. The fan operation is °
dependent on the fan mode selected, either continuous or
cycling. Dip switch 5 controls the fan mode, see “Dip Switch”
setting elsewhere in the manual.
Emergency Heat Operation
In the event of a compressor failure in heat pump mode the
compressor may be locked out to provide heat through the
resistance heater. This feature ensures that even in the unlikely
event of a compressor failure the room temperature can be
maintained until the compressor can be serviced. Dip switch 7
controls the emergency heat setting, see “Dip Switch” setting
elsewhere in the manual.
Fan Mode
Fan Only
Pressing the ‘ ’ button will run the fan to allow for Fan Only
air circulation in the room without operating the compressor
or heater regardless of the room or set temperature. The fan
speed selection is made by pressing either the ‘ ’ or High Fan
‘ ’ button. Low Fan
Cycle/Continuous
The owner may choose between fan cycling or fan continuous
mode based on property preference. (Note: Even heat
monitoring and quiet start/stop fan delay only operate in fan
cycle mode). Fan continuous mode is used to keep constant
airow circulation in the room during all times the unit is ‘ON’.
Fan cycle will conserve energy by only operating the fan while
the compressor or electric heater is operating. Dip switch 5
controls the fan mode, see “Dip Switch” setting elsewhere in
the manual.
The unit is factory congured to display all temperatures in
degrees Fahrenheit (°F). To switch to degrees Celsius press
the ‘Fan Only’ and ‘Low Fan’ buttons simultaneously for three
seconds. The display will show a ‘C’ as acknowledgement of
the change.
To revert back to degrees Fahrenheit press the ‘Fan Only’
and ‘Low Fan’ buttons simultaneously for three seconds.
The display will show an ‘F’ as acknowledgement of the
change.

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.
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 identied terminal is connected
to the “S” or start terminal. The identied 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.

1. Make sure the motor has cooled down.
2. Disconnect the fan motor wires from the control board.
3. Test for continuity between the windings also, test to
ground.
4. If any winding is open or grounded replace the motor.
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.
20
Refrigerant Charging
Proper refrigerant charge is essential to proper unit opera-
tion. Operating a unit with an improper refrigerant charge will
result in reduced performance (capacity) and/or efciency.
Accordingly, the use of proper charging methods during ser-
vicing 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 specic type of
failure will be inuenced 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 sufcient 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.
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
when working with refrigerants.
Failure to follow these procedures could
result in serious injury or death.

3. Introducing refrigerant charge into high side of the
system.
4. Accurately weighing the refrigerant charge introduced
into the system.
22
Overcharged Refrigerant Systems
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.
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 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
conrm, 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.
Restricted Refrigerant System
Troubleshooting a restricted refrigerant system can be
difcult. 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 specication.
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.
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 teon.
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.
23
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 PTAC 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.
TESTING THE 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.
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.
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.
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.
WARNING
HIGH PRESSURE HAZARD
24
Reversing Valve in Heating Mode
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.
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.
Reversing Valve in Cooling Mode
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
