1-12. EQUIPMENT CHARACTERISTICS. CAPABILITIES. AND FEATURES.
The air conditioner is a split pack unit that provides 30,000 British Thermal Unit per Hour (BTUH) cooling capacity. The
heating system of the shelter is incorporated with the control module to provide ease of operation of both heating and
cooling systems. The air conditioner operates on 28 volts direct current (VDC) at 66 amperes. The system is a sealed
unit and illuminates one of four warning lights on the control module should a problem occur. The air conditioner will also
automatically shut itself down to prevent further damage to the air conditioner or compressor. The compressor is not a
component of the air conditioner. The compressor is a component of the vehicle to which the air conditioner is mounted.
Refer to applicable technical manual for compressor information.
