DESCRIPTION AND USE OF

OPERATOR'S CONTROLS AND

INDICATORS

2-1. GENERAL

The Model F9000H-3 Air Conditioner is designed for a wide variety of installations and for operation under

a wide range of climatic conditions. It is also designed for continuous or intermittent operation as a self-

contained unit or may be connected to external filtering equipment for operation under chemical-biological-

radiological (CBR) environmental conditions. Operators must be aware of any peculiarities or operational

limitations for their specific installation.

2-2.

OPERATOR'S CONTROLS

See figures 2-1 and 2-2.

Under normal operating conditions, before starting the air conditioner in any mode, make sure that

the fabric cover on the back of the cabinet is rolled up and secured, that the condenser fan intake

screen and fan guard are in place and unobstructed, and the evaporator fan intake and discharge

grille louvers are fully open. EXCEPTIONS: Under extreme climatic conditions, such as

blowing snow, which might enter the compressor section, the unit may be operated in the

VENTILATE, LO HEAT or HI HEAT mode with the fabric cover rolled down and snapped in place.

When operated in this manner, outside air cannot be drawn through the fresh air damper, which

should be positioned fully closed. The fabric cover cannot be rolled down if the unit is connected to a

CBR filter.

DO NOT OPERATE IN THE COOL MODE WITH THE FABRIC COVER ROLLED DOWN.
