Better use of air conditioner

Never fail to observe the followings

Trouble shooting

Before asking for service, check the following first.

| Phenomenon| Cause or check points
---|---|---

Normal Performance inspection

| The system does not restart immediately.| 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.

Noise is heard

| 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.

| Is power plug inserted? Is there a power failure? Is fuse blown out?
| Poor cooling

| 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?

Application temp. range of air conditioner -7oC~43oC.
