Cabinet Color and Material
The air conditioners are available in two standard cabinet colors -the standard grey with beige as an
option. The standard cabinet’s sides, top and front panels are constructed of 16 gauge painted steel.
Contact your ICE representative for color chips, custom colors and 316 stainless steel cabinets.
1.8 Electrical Operation
The compressor and condenser fan are energized with a contactor controlled by a 24 VAC pilot
signal.
Some compressors incorporate an internal PTC crankcase heater that functions as long as primary power
is available. The heater drives liquid refrigerant from the crankcase and prevents loss of lubrication
caused by oil dilution. Power must be applied to the unit for 24 hours before starting the compressor.
The condenser (outside fan) motor is energized by the same contactor.
The indoor evaporator fan motor is controlled by the fan purge on the electronic control board.
