Clearance Check
Clearances around the unit should also be checked to make sure
that the intake air and discharge air paths have not become
blocked or restricted.
A
minimum of eight inches clearance is
needed from unit to furniture, beds, or other objects for proper
operation. Restricted discharge or intake air will reduce the
unit's operational performance. In severe airflow restrictions
damage can occur to unit components such as the compressor,
electric heater or fan motor.
OBTAINING SERVICE
In the event this unit requires repair or servicing beyond what is
covered in this manual, contact an authorized service organiza­
tion.
To obtain an authorized servicer, contact your sales representa­

NORMAL OPERATING
SOUNDS AND CONDITIONS
fml
Water trickling sounds
Water is picked up and distributed over the coil. This
improves the efficiency and helps with water removal.
I§] Water dripping
Water will collect in the base pan during high humidity days.
This can cause overflow and drip from the outside of the unit.
fml
Air sounds
The fan cycle switch sets the operational mode of the fan in
the ON position. The fan
will
run continuously whenever
power is applied in this mode. In the AUTO position, the fan
will
cycle on and off with the compressor or electric heater.
I§] Starting delay
You may notice a few minutes delay in the starting if you
try to restart the unit too soon after turning it off or if you
adjust the thermostat right after the compressor has shut
off. This is due to a built in delay to protect the compres­
sor.
