Your air conditioner must be connected to a power supply with the same
AC voltage and hertz rating as marked on the nameplate located on
the chassis. Only alternating current (AC) can be used. Consult page
3 for the correct type of receptacle for your model.
An overloaded circuit will invariably cause malfunction or failure of
an air conditioner, therefore, it is extremely im port ant that the
electrical power and the wiring is adequate. Consult your dealer or
power company if in doubt.
CIRCUIT PROTECTION - Before installing or relocating your
Friedrich Room Air Conditioner, check the amp rating of the circuit
breaker or "TIME-DELAY" fuse. Refer to the nameplate located on

the value stated on the nameplate. If the air conditioner is connected
to a circuit protected by a fuse, a "TIME-DELAY" fuse must be
used due to the momentary high current demands when your air
conditioner is started.
WARNING
Electrical Shock Hazard
Use correct circuit protection.
Failure to follow these instructions can
result in death, fire, or electrical shock.

Things to know about a 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
o

outdoor air passing over cold (below freezing) coil surfaces.

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 defrost the outdoor coil. After the defrost is completed,
the unit will automatically return to the heat pump mode.
3. Steam may be seen rising from the outdoor coil during the
defrost. This is similar to expelling warm breath on a cold
morning.
4. If the outdoor temperature drops below 43°F during heat
pump operation, your WallMaster Heat Pump will automati-
cally switch to electric resistance heat and will continue to
operate in this mode as long as the outdoor temperature
remains at 43º F or below.
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before
operating.
Failure to do so can result in death or
electrical shock.
