solving, please refer to Diagnostic Codes & Solutions
and Troubleshooting sections, pages 13 & 14.
When condenser coil temperature ex-
ceeds the presetting point, compressor
decreases the operating frequency to
30Hz. If this protection is inactive and
condenser coil temperature reaches the
shut-down point, the compressor will
be turned off. Thus providing double

seal prevents water from entering the control area or the
fan motor and damaging the unit.
2. Spray condenser coil and base pan down with water.
Next spray a mild biodegradable detergent onto the
condenser coil and base pan. Let set for five (5) minutes.
3. Rinse condenser coil and base pan with water again.
NOTE: Ensure water pressure is no higher than that of an
ordinary garden hose and the water temperature no higher
than 120℉.

Routine scheduled Maintenance
To achieve continuing top performance and high efficiency,
establish a “once a year" cleaning/inspection schedule for
the unit. Take the unit out of the sleeve and thoroughly
clean and rinse. Be sure to include in the yearly cleaning
the evaporator coil, and condenser coil, basepan, and
drain passages.
Scheduled maintenance can be accomplished by either
qualified local maintenance staff or by an authorized
servicer. They must follow the instructions described in this
manual.
Adverse Operating Conditions Maintenance
Units operating in dusty or corrosive locations; i.e.
dusty construction site or sea coast, must be cleaned
more often. A minimum of four (4) times a year will
maintain proper operational conditions and protect unit
components.
Wall sleeve
Clean the wall sleeve while cleaning the unit. The
caulking around the sleeve should be checked to make
sure that any potential air and water openings around
the sleeve are properly sealed. The wall sleeve's level
should also be rechecked. Proper leveling for most
installations are a 1/4 bubble tilt to the outside and
level from right to left. Contact your sales person for
detailed maintenance or cleaning instructions.
The front panel does not
need to be removed.
Filter is removed by grasping
the filter's top and gently
pulling up
2. Pull the filter straight up and remove.
3. Clean filter with vacuum or with running water.
Reverse this procedure to reinstall the filter.
CAUTION!
DO NOT USE COMMERCIAL GRADE COIL CLEANERS. SOME
OF THESE CLEANERS MAY CONTAIN ETHYLENE DIAMINE
TETRACETIC ACID (EDTA) WHICH CAN SHORTEN THE LIFE
OF THE CONDENSER COIL.
4. Tilt the non-compressor side of the unit up no higher
than 45 degrees and allow water to drain out the other side
of the unit.
5. Remove excess water left in the base pan by wiping the
base pan with a dry cloth.
6. Remove the water-tight seal from the motor and
control panel area.
7. Reinstall unit back into wall sleeve.
8. Allow unit to dry for 24 hours before reapplying power.
When power is reapplied test unit for proper operation.
9. Place a non-acidic algaecide in the base pan to inhibit
bacteria growth. Ensure the algaecide is compatible with
wet coil operation and is not corrosive to the coil.
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.
NORMAL OPERATING SOUNDS
AND CONDITIONS
Water trickling sounds
Water is picked up and distributed over the coil. This
improves the efficiency and helps with water removal.
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.
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.
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
compressor.
Buzzer Response
The buzzer will chime “Di”(0.1 sec) as response when
receiving the effective order from key pad control and
remote control.
