Troubleshooting tips and home maintenance
Won't cool
If the trait operates, but won't cool, determine if the controls
are properly set. Wait three minutes betbre setting the ther-
mostat to a cooler position in order to check control settings.
Check the filter and clean it thoroughly, if needed. Check
to see if the vent door is closed. Check to see if the chassis
seal gasket is properly installed (refer to page 12 tBr seal
gasket installalation).
Won't heat (for heat/coolmodelsonly)
If the trait operates, but won't heat, determine it the control
settings are correct. Adjust the thermostat to a warmer position
to determine if it operates. Also, check the filter and clean it
thoroughly, if needed.
Odors in heating(for heat/coolmodelsonly)
You may notice a smoke odor the first time the heater element
comes on. This is common in any type of heat system when
first turned on tBr the winter. The odor comes flOln dust and
other particles that accumulate during the warm mouths. The
odor will dissipate quickly.
Won't run
If the unit thils to operate, check to see it the power cord
is firmly plugged in. Check tbr blown fuses, tripped circuit
breakers or a tripped LCDI Device (Refer to page 7 lBr LCDI
reset instructions). Restore the circuit breaker or replace the
blown fuse with a proper size "TIME-DELAY"
fuse. The
proper fuse size is sfiowu on pages 2 and 5 in these instructions.
Alter restoring tile current supply to the unit, wait three mi uutes
belbre restarting.
Frostingof the indoorcoil
Certain operating conditions may produce indoor coil frost.
During the cooling operation, a dirty filter or restricted air
distribution in combination with cool, damp weather could
cause such an occurrence. Should the indoor coil frost over
while cooling, set the control to FAN and keep it running
until the frost on the coil is gone. Setting the thermostat to
a slightly warmer position will probably keep the coil from
frosting over agai u.
Cleaningthe decorativefront
The decorative front of your Friedrich room air conditioner, as
well as the complete can net, may be cleaued with warm water
and mild detergent. Under adverse operating conditions, the
indoor and outdoor coils and base pan may require periodic
cleaning to maintain efficient operation. Your Friedrich dealer
should be called when this service is required.
Thingsto know abouta WallMaster heat pump
During the heat pump operation, you may notice some functions that did not occur when the unit was used for cooling:
1. It is common for ice to form on the outdoor coil of your WallMaster Heat Pump. The ice forms due to moisture in the
outdoor air passing over cold (below freezing) coil surt_aces.
2.
When the outdoor coil forms ice, your heat pump will automatically initiate a defrost. The compressor will stop and
the fan will continue to run. The electric heat will be turned on to continue warming the room while the outdoor air
defrosts the outdoor coil. Alter the defrost is completed, the unit will automatically return to the heat pump mode.
3.
It isnonnal for vapor (steam)to rise from the outdoor coil during the defrost. This is similarto expelling warm breath
on a cold morning.
4.

43°Fduring heat pulnpoperation, yourWallMasterHeat Pump will automatically
switch to electric resistance heat and will continue to operate in this mode as long as the outdoor temperature remains
at 43°F or below.
