Specifications EnErgy Star® models
WALLMASTER HEAT PUMP
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 perfor-
mance will be satisfactory.
Note: all models will produce condensate. If condensate disposal is desired, an
optional drain kit is available.
DEFROST CONTROL: Initiated at 20°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. During electric heat mode,
the unit will achieve the following ratings: 11000/9100 BTU/h, 16.0/14.7 amps,
and 3550/2950 watts.
DEFROST DRAIN: Drain automatically opens at approximately 50°F to prevent
condensate from freezing inside drain pan.
WallMaster Heat Pump heating information (shown in red) indicates heat pump heating performance. WallMaster Electric Heat heating information (shown in red)
indicates electric heat strip performance. For WallMaster Heat Pump electric heating performance refer to corresponding WallMaster Electric Heat model.
