TROUBLESHOOTING & WARRANTY

TROUBLE

POSSIBLE CAUSE

Air conditioner can not operate at all.

· Has the power been shut down? · Is the wiring loose? · Is voltage too high or too low ?
(measured by professionals) · Does it reach the set time for start up? · Does the circuit protection device trip?

Remote control is not available.
Cooling (Heating) efficiency is not good.

· Is the remote control out of effective distance to the indoor unit?
· Are there any obstructions between the controller and the signal receptor?
· Is the battery exhausted?
· Is the setting temperature suitable? · Is the air inlet or outlet obstructed? · Is indoor fan speed set at low speed? · Is there any heat source in your room? · Is the air filter dirty?

Indoor unit does not operate Immediately when the air conditioner is restarted.

If the air conditioner is turned on immediately after it is turned off, the protective delay switch will delay the operation for 3 to 5 minutes.

There is unusual smell blowing from the outlet after operation is started.

The air conditioner itself does not have an undesirable odor. If there is an odor, it may be due to accumulation of the odor in the environment. Please clean the air filter or activate the cleaning function.

There is sound of running water during the running of air conditioner.

Sometimes the “hissing” sound of running
water can be heard. This is the sound of the flow of the refrigerant, not a malfunction.

A slight “click” sound is heard at the of start-up or shut-down.

Due to temperature changes, panel and other parts will swell, causing the sound of friction. This is normal, not a fault.

During the cooling operation, the indoor unit outlet sometimes will blow out mist.

This is because the indoor air is cooled rapidly. After it runs for some time, the indoor temperature and humidity will be reduced and the mist will disappear.

WARNING – Immediately stop all operations and turn off the power

supply, contact a Service center locally in following

situations.

· Shrill sound is heard or an unpleasant odor is emitted during the

operation.

· There is an abnormal heat in power supply cord and power plug.

· Accidentally pour impurities or water into the machine or the remote

control.

· Air switch or protection switch often breaks.
