Before operation
a.
(1) Check to see that powercable has been connected to a source of 208 volt,3phase,4 wire, 400 hertz power
for models F36T4-2S, F36T4-2SA, and F36T4-2SB or 208 volt, 3 phase, 4 wire, 50/60 hertz power for mod-
els F36T-2S and F36T-2SA, and to the input power connector on the unit.
NOTE
When possible power should be connected to the unit at least 30 minutes prior to operat-
ing in the COOL mode. This is critical when outside temperatures are cold and unit is
to be operated in the COOL mode. The compressor is equipped with a warm up heater
and thermostat that will not allow the compressor to operate prior to complete warm up.
The unit will operate immediately (fans only) in the COOL mode. the refrigeration system
(compressor) will operate only when warmup incomplete (Iess than 30 minutes). If addi-
tional cooling is required fresh air damper can be opened. When compressor reaches
safe operating temperature it will start automatically. Fresh air damper and Tempera-
ture control thermostat can then be adjusted to suit,
the compressor is also equipped with a heater that will keep it warm so long as unit re-
mains connected to the power source.
(2) Check that fabric cover has been unsnapped, rolled up, and secured with both straps to the two turn button
fasteners.

mode, make sure that the fabric condenser cover on the back of the condenser
section is rolled up and secured and that ail screens and guards are in place and
unobstructed.
EXCEPTION:

which might enter and damage condenser section, the unit may be operated in
the VENTILATE, LO HEAT, or HI HEAT modes with the fabric cover rolled down
and snapped in place.
DO NOT OPERATE IN THE COOL MODE
