COMPRESSOR

cated and requires no additional oiling.
FRONT PANEL AND GRILLE
The front panel and grille can be cleaned with a mild soap
or detergent. Do not use hydrocarbon-based cleaners (e.g.
acetone, benzene, naphtha, gasoline, etc.) to clean the front
panel or grille.Use care when cleaning the control area.
Do not use an excessively wet cleaning cloth.
SCHEDULED MAINTENANCE
To achieve continuing top performance and high efficiency,
a regular cleaning/inspection schedule must be established.
Maintaining this schedule can be accomplished by either a
local maintenance staff or an authorized servicer and must
follow the instructions described in this manual.
• If the unit is operated in a dusty climate, dust may
collect in the basepan and clog the condenser coil. It is
advisable to remove the unit from the sleeve and thor-
oughly clean the basepan and condenser coil on a
periodic basis.
• If the unit is installed ocean side or in a corrosive
atmosphere, its life may be greatly reduced by the
corrosive environment. Under these conditions, the unit
should be removed from the sleeve and completely
cleaned once a year. At that time any scratches or
blisters on the painted surfaces should be sanded and
repainted.
OUTDOOR COIL CLEANING
The coils on the outdoor side of the air conditioner should be
checked regularly. For cleaning outside coil, remove the 6
screws that mount the condenser coil top cover to condenser
shroud.
Normal Operating Sounds and Conditions
POPPING OR GURGLING SOUNDS
This sound is the refrigerant traveling through the lines.
This is a normal sound which may be heard for a few
seconds after the unit shuts off.
WATER TRICKLING SOUNDS
This sound is produced by the water as it is picked up
and run over the coils. This procedure improves the
efficiency of the unit and helps with water removal.
WATER DRIPPING
Water will collect in the basepan during high humidity
days.
STARTING DELAY
You may notice a short delay in the startup 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 delay protects the compressor.
