a. Determine length of cable required to connect the air conditioner to power source.
2) to match
the electrical connections
on the power source
to be used. Refer
OPERATIONAL CHECK. To perform
an operational check
of the air conditioning unit,
do the following steps.
(a) Operation Checks.
(1) Be sure the mode selector switch is in the OFF position and reconnect input power.
If power has just been connected to unit, a short (30 minute
maximum during very cold weather) warm up period is required
for COOL mode operation.
operating temperature, it will come on automatically if the mode
selector is in the COOL mode.
(2) Check that the fabric cover is rolled up and secured.
(3) Adjust conditioned air intake and outlet louvers to the full open position.
(4) Adjust fresh air damper to full closed position.
(5) Turn mode selector switch to VENTILATE. Fan should start.
(6) Use a paper streamer or smoke and note amount of air being discharged from
conditioned air outlet grille.
(7) Open fresh air damper fully.
(8) Close conditioned air intake guard louvers fully.
(9) Again check air flow as in step f. above.
Air flow should be approximately the same.
(10) Fully open louvers in conditioned air intake grille and fully close fresh air damper.
(11) Turn temperature control thermostat knob to fully INCREASE (clockwise) position and
then turn mode selector switch to LO HEAT. Place your hand in air flow from the conditioned
air outlet grille and feel for a temperature rise. When discharge air temperature has reached a
relatively stable level, turn mode selector switch to HI HEAT and feel for a further temperature
rise. Next, turn temperature control thermostat knob to fully DECREASE (counterclockwise)
position. Feel that discharge air temperature drops to approximately same relatively stable level
previously noted in LO HEAT. Finally, turn mode selector switch to LO HEAT and feel
discharge air temperature drop to ambient level.
