Main points of Operation

Prevent Cool Air Blowing Off

In heating mode,the indoor fan will not run immediately after the unit starts to prevent the cool air blowing off.

Defrosting Function

In heating mode, when frost formed on the outdoor heat exchanger, the air conditioner will automatically defrost a few minutes. During defrosting, both indoor and outdoor fan will stop running. When defrosting finished, air conditioner will automatically back to running.

Hints

The air conditioner absorbs heat form outside and releases inside when in heating mode, therefore the outside environmental temperature will affect heating effects.

Power Failure Compensation(to be applied for a necessary situation):

After the power failure compensation is set, if power failure suddenly occurs while the air conditioner is working,it will resume the previous working state when the power is supplied again.

Setting Method: When the remote controller is on (excluding timer mode and fan mode),press the ìsleepingî button on the remote controller 10 times within 5 seconds,and after the buzzer rings 4 times,the air conditioner will enter the state of power failure compenstation.

Cancel Method:Press the ìsleepingî button on the remote controller 10 times within 5 seconds, and after the buzzer rings 2 timer,the power failure compensation mode will be cancelled.

Note: When a power failure suddenly occurs during the air conditioner si working after the power after the power failure compensationis set,if the air conditioner will not be used for a long time, please cut off the power supply to prevent its operation from being res umed after the power is supplied again, or press the ì Switch On/Off î button after the power comes again.

Post-season Care

Troubleshooting

The followings are not malfuncition

Hua

Water flowing sound is heard

When the air conditoner is started, when the compressor starts or stops during operation or when the air conditioner is stopped,it sometimes sounds ì Bi- Bi-î or ìGodo-Godoî. It is the flowing sound of the refrigerant , not a malfunction.

Cracking sound is heard

It smells.

This is caused by heat expansion or contraction of plastics

Air blown out from the indoor unit sometimes smells. The smell results from smells of furniture, paint , tobacco absorbed by indoor unit.

During operation, white fog comes out of indoor unit.

When in COOL or DRY mode, a thin water fog can be seen blown out of unit ,this is the condensed fog because the suddenly cooled indoor air is blown out.

Automatically switch into FAN mode during cooling.

To prevent frost from being accumulated on the indoor unit heat exchanger, it sometimes automatically switched into the FAN mode,but it will soon back to the cooling mode.

The air conditioner cannot be restarted soon after it stops. Air conditioner does not start?

This is because of the self-protection function of the system, therefore,it cannot be restarted for about three minutes after it stops.

Air does not blow or the fan speed cannot be changed during drying.

In DRY mode, when room temperature becomes 2 C higher than temperature setting, unit rill run intermittently at LO speed regardless of FAN setting

Please wait for three minutes
