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)

!

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.
