Cooling Operation
•
Turn the selector switch to the “Low Cool” or
“High Cool” position.
•
Rotate the temperature control to the position
that is the most comfortable to you. When the
temperature of the air entering the air
conditioning unit rises a few degrees above
the setting you have selected, the thermostat
will turn the compressor on. When the
temperature of the air entering the air
conditioning unit drops below the selected
setting, the thermostat will turn the
compressor off. When the air conditioner is in
the cooling mode, it will continue to cycle the
compressor on and off until the selector
switch is turned to another operation mode.
•
Position the louvers to the desired direction
the discharge air is to flow.
During Cooler Nights
When outdoor temperatures drop in the
evening or at night below 75 degrees F, the
temperature control needs to be set at midpoint
between “Warmer” and “Cooler”. If the setting is
at “Cooler”, the evaporator coil may become iced
up and stop cooling. During the day when
temperatures have risen to at least 75 degrees F,
reset the thermostat switch to the desired setting.
NOTE: Should icing up occur, it is necessary to
let the evaporator coil defrost before
normal cooling operation is resumed. At
this time, operate the air conditioning
unit in the “High Fan” position with the
system at maximum airflow. When
increased or full airflow is observed, the
evaporator coil should be clear of ice.
