Section I DESCRIPTION AND USE OF OPERATOR'S CONTROLS AND INDICATORS
G E N E R A L.
The Model F9000H-3SA, and F9000H-1SA, AirConditioners are designed for a wide variety of installations and
for operation under a wide range of climatic conditions. They are also designed for continuous or intermittent
operation as self-contained units or maybe connected to external filtering equipment for operation under
Nuclear Biological and Chemical (NBC) environmental conditions. Operators must be aware of any peculiarities or
operational limitations for their specific installation.
All necessary operator controls are illustrated in Figures 2-1 and 2-2. Usage of controls is detailed in Operational
Checks (para 2-6)
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 that 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 VENT, LOW HEAT or HIGH 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 NBC filter.
DO NOT OPERATE IN THE COOL MODE WITH THE FABRIC COVER ROLLED DOWN.
