Troubleshooting

Poor cooling

Is there any direct sunlight in the room?

If there are unexpected heat sources in the room?

Too many people in the room?

Cold air blows out (in heating mode). Is air conditioner in standby condition in heating mode?

If your unit still can't work properly after above mentioned checks, or following problems occur, please stop it immediately and contact your dealer.

Fuses or circuit breakers often blow out.

Water comes out in cooling/dry operation.

Operation is abnormal or sound is heard.

When failure happens,the fan of indoor unit stop running.

For indoor failure, only running LED of remote receiver will indicate,

For outdoor failure, timer LED and running LED will indicate .timer LED of remote receiver stands for ten's place, and running LED stands for one's place. Timer LED will flash firstly, 2 seconds later, running LED will flash too.After that finishes, 4 seconds later, they will flash in turns again. Flash times is the failure of outdoor + 20.

For example,failure code that outdoor is 2, so indoor unit should display 22. As a result, timer LED flashes twice firstly, then running LED flashes twice,But when outdoor failure LED flash 20,the indoor unit will flash 42,it's a special.
