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.
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 (0.1 sec) as response when
receiving an order from key pad control and remote
control.
DIAGNOSTIC CODES
The Diagnostic Maintenance provides detailed
information on PTAC control operation and operational
status including present modes, failures, airflow
restriction warnings, operating temperatures, and past
failures.
To enter Diagnostic Status Report mode,press and
hold the down arrows and,while holding press the FAN
SPEED key for a period of five (5) seconds.
The meaning of figure on display pad is as below:
X.X---(0~4: time of protection)
L---is protection mode(1: anti-frost; 2: overheat; 3: high
pressure; 4: anti-freezing)
Failure

CAUTION
HIGH PRESSURE AND HIGH TEMPERATURE CLEANING IS
NOT RECOMMENDED.
DOING SO COULD DAMAGE THE ALUMINUM FIN STOCK
AND ELECTRICAL COMPONENT.
!
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.
