HEATING PERFORMANCE:  Change-over from heat pump operation 
to resistance operation on models indicated is automatic at a preset 
outside ambient temperature of approximately 35°F.
Calculate the heat loss of the space to be heated. As long as the heat loss 
does not exceed the resistance heating capacity rating of the unit, the 
heating performance will be satisfactory.
Note: all models will produce condensate. If condensate disposal is 
desired, an optional drain kit is available.
DEFROST CONTROL: Initiated at 30°F (outdoor coil temperature) and 
terminated at 43°F (outdoor coil temperature). During defrost, the 
compressor stops and the electric heat starts, then operates with 
the fan to maintain indoor comfort. Below 43°F, the unit remains in 
electric heat mode.
DEFROST DRAIN: Drain automatically opens at approximately 50°F to 
prevent condensate from freezing inside drain pan.
Heat Pump heating information (shown in red) indicates heat pump heating performance. Electric Heat heating information (shown in red) 
indicates electric heat strip performance. For Heat Pump electric heating performance refer to corresponding Electric Heat model.

Power cords are located on front left of WallMaster models.
Due to continuing research in new energy-saving technology, specifications are subject to change without notice.
As an ENERGY STAR
®
 partner, Friedrich Air Conditioning Co. has determined that the selected ENERGY STAR
®
 models meet the  
ENERGY STAR
®
 guidelines for energy efficiency.
EER is the unit’s Energy Efciency Ratio; CEER is the unit’s Combined Energy Efciency Ratio.
Your energy costs will depend on your utility rates and use. The estimated energy cost is based on a electricity cost of $.12 per kWh.
