TROUBLESHOOTING TIPS

Normal function of the air conditioner

The following events may occur during normal operation.

Protection of the air conditioner.

Compressor protection

- The compressor can't restart for 3-4 minutes after it stops.

Anti-cold air (Cooling and heating models only)

• The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in

one of the following three situations and the set temperature has not been reached.

A) When heating has just started.

B) Defrosting

C) Low temperature heating.

• The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).

Defrosting (Cooling and heating models only)

- Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low

and humidity is high resulting in lower heating efficiency of the air conditioner.

• During this condition air conditioner will stop heating operation and start defrosting automatically.

• The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and

the amount of frost built up on the outdoor unit

1. A white mist coming out from the indoor unit

- A white mist may generate due to a large temperature difference between air inlet and air outlet

on COOL mode in an indoor environment that has a high relative humidity

- A white mist may generate due to moisture generated from defrosting process, when the air

A white must may generate due to moisture generated from a conditioner restarts in HEAT mode operation after defrosting.

1. Low noise of the air conditioner

• You may hear a low hissing sound when the compressor is running or has just stopped running.

It is the sound of the refrigerant flowing or coming to a stop.

• You can also hear a low "squeak" sound when the compressor is running or has just stopped

running. This is caused by heat expansion and cold contraction of the plastic parts in the unit

when the temperature is changing

- A noise may be heard due to louver restoring to its original position when power is turned on.

1. Dust is blown out from the indoor unit.

This is a normal condition when the air conditioner has not been used for a long time or during first

use of the unit

1. A peculiar smell comes out from the indoor unit.

This is caused by the indoor unit giving off smells permeated from building material, from furniture.

or smoke.

1. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and

heating models only) mode.

When indoor temperature reaches the temperature setting on air conditioner, the compressor will

stop automatically, and the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling and heating

TROUBLESHOOTING TIPS

1. The air conditioner runs And child after turning off the unit.
   When turning off the unit under COOL(AUTO COOL, FORCED COOL) and DRY mode, the air conditioner will run Air condition of Auto air intake HEAT mode, the unit will continue operating for about 30 seconds at LOW fan speed then stop the operation and turn off the unit automatically.
2. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative humidity higher than 80%). Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.
3. Heating mode (For cooling and heating models only)

The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation. When the outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature can't be achieved by the air conditioner, we suggest you use a supplementary heating device.

1. Auto-restart function

Power failure during operation will stop the unit completely.
- For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit starts flashing. To restart the operation, push the ON/OFF button on the remote controller. For the unit with Auto-restart feature, when the power restores, the unit
- For some models, the machine is special designed with Auto-restart function for the open angle of the horizontal louver.Power failure during operation or pressing the ON/OFF button on the remote controller will stop the unit completely.When the power restores or pressing the ON/OFF button on the remote controller again,the unit restarts automatically with all the previous settings including the open angle of the horizontal louver by the memory function. So we strongly suggest that the open angle of the horizontal louver should not be set too small,in case the condensed water forms and drops from the horizontal louver. Press the AUTO/COOL button under the front panel and the open angle of the horizontal louver will be restored to the standard angle when the condensed water forms on the horizontal louver.
11. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction. Disconnect the unit with power and then re-connect the unit with power again. Push the ON/OFF button on the remote controller to restart operation.
12. The protection of outdoor low temperature(on some models)

The protection of outdoor low temperature can be activated only in the HEATING mode. The unit will stop operating and display "P3" on the LCD window of the indoor unit when the outdoor temperature is or lower than 5 F(-15 C) for one hour, but the indoor unit in this situation can still receive the signal from the remote controller. The unit will restart automatically with all the previous settings preserved by the memory function when the outdoor temperature is or higher than 11 F(-12 C) for 10 minutes and the compressor stop operating for more than one hour, or when the outdoor temperature is or higher than 41 F(5°C) for 10 minutes.
