Unit Operation
Standard air cooled condensers function as the
outdoor condensing units for appropriately sized split
refrigeration systems. These units, operating in
conjunction with a matched indoor compressor/
evaporator configuration, provide refrigerant
condensing for these systems down to a normal
ambient temperature of 40º F. Operation to 0º F ambient
is possible with the addition of externally mounted low
ambient dampers.
All condenser fans are direct drive, 26 inch propeller
type. They are driven by 1 HP thermally protected
motors.
When wired properly, the unit will start and operate
satisfactorily as long as the operating temperature is
