(8) Operates in environmental conditions from tropic to arctic.
(9) Is fully portable.
(10) Designed for low-noise level operation.
c. Special features.
The control panel may be removed from the unit and remote mounted.
(1) Fresh Air Filter -- Provides filtered outside air.
(3) High Pressure Cutout Switch -- This switch is factory set to shut off the compressor if the refrigerant
discharge line pressure rises to 480 + 10 psig (33.75 + .7 kg/cm 2) (4) Low Pressure Cutout Switch -- This
switch is factory set to shut off the compressor if the refrigerant suction line pressure drops to 15 + 3 psig
(1.05 + .2 kg/cm 2).
(5) Refrigerant Sight Glass (liquid sight indicator) -- Allows visual inspection and indicates condition of
liquid refrigerant when the unit is operating in the cool mode. A moisture indicator in sight glass indicates
possible moisture contamination of refrigerant.
(6) Condenser Coil -- Serves as a heat exchanger by transferring heat from the refrigerant passing through
the tubing to the air passing over the tubing and fins.
(7) Evaporator Fan Assembly -- Draws air into the evaporator section and exhausts it through the evaporator
(cooling) coil and heater elements and into the room or enclosure.
(8) Evaporator Coil -- Serves as a heat exchanger by transferring heat from the air passing over the tubing
and fins to the refrigerant passing through the tubing.
(9) Fabric Cover -- Shown in stowed (operational) position. When rolled down and snapped it protects the
rear (exposed) surface of the unit.
