For twice press, disappears,the operation stops.

When indoor fan motor is running, it has healthy process function. (It's available under any mode)

BRIEF INTRODUCTION TO HEALTH ANION FUCTION

The anion generator in the air conditioner can generate a lot of anion effectively balance the quantity of position and anion in the air and also to kill bacteria and speed up the dust sediment in the room and finally clean the air in the room.

About UV light degerming function

UV light emitted by the UV light device of the indoor unit catalytically activates the nano TiO2 on the multi-lights touching intermediary, and the degerming effect is highly efficient and lasting.

Note: when the function is running, don't open the inlet grille.

Under the cooling or dehumidifying mode, the horizontal air door blade shall not keep the downward position for a long period.Otherwise the air outlet will condense water and produce water drops. Do not expose your skin under cool air or hot air for a long period.

Remote monitoring

The control board of the indoor unit reserves the communication port for remote control. If you install the peripheral equipment according to the manual of the matching remote control detector, it can realize the computer management or remote monitoring of the conditioner. Please refer to the manual of the "Conditioner remote control detector " for the details.

Trouble display

Do not use water, wipe the controller with a dry cloth.Do not use glass cleaner or chemical cloth.

Do not use the following for cleaning

Gasoline,benzine, thinner or cleanser may damage the coating of the unit.

Air Filter cleaning

Indoor Body

Wipe the air conditioner by using a soft and dry cloth.For serious stains,use a neutral detergent diluted with water.Wring the water out of the cloth before wiping.then wipe off the detergent completely.

Hot water over 40OC(104OF) may cause discoloring or deformation.

Press the clasp on the top of the grill and pull the grill out, and then the filter will be taken out along a gradient way.

Clean the filter.

Use a vacuum cleaner to remove dust, or wash the filter with water.After washing, dry the filter completely in the shade. Then, reinstall it onto the unit.

Once every two weeks

Page 23

Maintenance

To Keep Your Air conditioner in Good Condition after Season.

1. Operate in FAN mode for about half a day.

On a fine day, unit shall be started and operate in FAN mode for about half a day until the inside of the unit becomes thoroughly dry.

2. Put off the power supply cord.

3. Cleaning the body.

4. Take out the batteries from the wireless remote controller.

Page 24

Maintenance

Before Setting in High season

1. Cleaning the standard air filter.

Operation without filter may cause troubles.Be sure to attach both right and left filters prior to the operation. Each of them are of different shapes.

2. Connecting the earthing cable. Caution

Incomplete earthing may cause an electric shock.

3. Do not block the air inlet or outlet.

4. Plug-in

Caution

After brush away dust at the plug, insert the plug of the power supply cord into the outlet completely.In case of suing exclusive circuit breaker,switch on the circuit breaker.

Trouble shooting

Before asking for service, check the following first.

Normal Performance inspection

Phenomenon

The system does not restart immediately.

Noise is heard:

Smells are generated.

Mist or steam are blown out.

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.

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

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?
