Frosting of the indoor coil

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 again.

Cleaning the decorative front

The decorative front of your Friedrich room air conditioner, as well as the complete cabinet, may be cleaned with warm water and mild detergent. Under adverse operating conditions, the indoor and outdoor coils and base pan may require periodic cleaning to maintain eficient operation. Your Friedrich dealer should be called when this service is required.

Wall preparation

STEP 1 The wall opening required for a WSD SLEEVE is 17 ¼" high by 27 ¼" wide.

STEP 2 LINTELS must be used in opening of brick veneer and masonry walls to support the material above the WSD SLEEVE. The following considerations should also be given:

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 outdoor ir 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.

B.A minimum distance of 1" must be allowed on all sides of the unit to adjacent wall and floor. Where the subbase is required, the minimum distance from the floor to the sleeve must be 3 ½". To minimize chances of short cycling of the compressor, the minimum clearance between the ceiling and the top of the unit should be 24". (See Figure 7).

A.Adjustable SUBBASE (SB) or other unit support must be provided for panel wall type construction and for walls less than 8" thick.
