Solution
Set the unit to be in cooling mode,
and lower the set temperature (pg.
13).
The compressor may take up to 3
minutes to turn on, or longer if it is
too warm.
Lower the room temperature to be
below 9o°F degrees.
Clean the filters.
(pg. 16)
Remove any obstructions in the
exhaust hose and port.
The unit must be vented. (pg. 4)
Minimize the size of the area to be
cooled, i.e. adding a drop ceiling.
Use more than one unit to cool the
area, or use a larger unit.
Close any open doors and windows.
Remove or shut off additional heat
sources such as radio equipment,
servers, etc.
Properly insulate the room to be
cooled, i.e. using fiberglass.
The unit may not work if the room
temperature is above 9o°F.
Close curtains or pull down blinds,
and minimize the direct sunlight
into the room.
Clean the filter and replace it if
needed.
Carefully vacuum the coils clean.
Remove anything blocking the
ports.
NOTE: If the ambient temperature is above 9o°F the unit may not blow cold air.
TIP: Run the unit before it is needed. For example, run the unit in the rooming before the area gets hot, and
continue to run the unit all day long in order to maintain a low temperature.
