General Information (To increase comfort and save energy.)
(1) During warm or cold weather.
(Air conditioner operation in COOL or
HEAT modes.)
o
Limit traffic through doors as much as possible.
l
Keep doors and windows tightly closed.
l
Limit use of fresh (outside) air.
NOTE
It is normally better to keep the fresh air damper slightly
open.
This will create a slight overpressure, provide
replacement oxygen, and reduce room odors.
Damper should be
closed during extreme weather conditions and during periods
when fast warmup or cooling is necessary.
l
Do not adjust controls unnecessarily.
Properly set the controls (See para
2-8 thru 2-11) and the unit will automatically control the temperature. The
Temperature control thermostat on the control panel operates like a conven-
tional room thermostat except that the temperature scale is not marked on
the control panel.
The thermostat has a control range of 40°F to 90°F (5°
to 32°C).
The centered position of the control knob would be approximately
65°F (18°C).
The full INCREASE would be 90°F (32°C). The full DECREASE
would be 40°F (5°C).
(2) During cold weather
l
Adjust shades, blinds, etc. (when applicable) to admit sunlight during day.
Close them at night.
l
Adjust the conditioned air outlet dampers slightly downward.
(3) During hot weather
Adjust shades, blinds, etc. (when applicable) to block out sunlight during
day.
l
Adjust the conditioned air outlet dampers slightly upward.
