6.Close the Inlet Grille

Close the Grille surely

NOTE:

The air purifying filter of the bacteria-killing medium and the the multi-lights touching intermediary accessories with machine will be used based on real situation.

The bacteria-killing medium air purifying filter is available for a long time and needn't to be changed. But it must be noticed to use the vacuum cleaner frequently to adsorb the dusts covering the purifying filter lest the covering dusts effect the function of the bacteria-killing medium air purifying filter. (It is strictly prohibited for the bacteria-killing medium air purifying filter to be washed)

The air purifying filter of the multi-lights touching intermediary will be solarized in fixed time.

In normal family,it will be solarized every 6 months. The solarization time will last no less than 8 hours under the state of abundant sun.

Trouble shooting

Before asking for service, check the following first.

Normal

Performance inspection

Phenomenon

The system does not restart immediately.

Noise is heard:

Cause or check points

When unit is stopped, it won't restart immediately until 3 minutes have elapsed to protect the system.

When the electric plug is pulled out and reinserted, the protection circuit will work for 3 minutes to protect the air conditioner.

During unit operation or at stop, a swishing or gurgling noise may be heard. At first 2-3 minutes after unit start, this noise is more noticeable. (This noise is generated by refrigerant flowing in the system.)

During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperature changes.

Should there be a big noise from air flow in unit operation, air filter may be too dirty.

Smells are generated.

This is because the system circulates smells from the interior air such as the smell of furniture, cigarettes.

Mist or steam are blown out.

During COOL or DRY operation, indoor unit may blow out mist. This is due to the sudden cooling of indoor air.

Multiple check

Does not work at all.

Poor cooling

Is power plug inserted?

Is there a power failure?

Is fuse blown out?

Is the air filter dirty? Normally it should be cleaned every 15 days.

Are there any obstacles before inlet and outlet?

Is temperature set correctly?

Are there some doors or windows left open?

Is there any direct sunlight through the window during the cooling operation?(Use curtain)

Are there too much heat sources or too many people in the room during cooling operation?
