Operation hints

Unit operation

Protection devices inside the unit will activate to stop unit operation, when ambient temp. is extremely low or high. When unit is running under high humidity in cooling or dehumidifying mode, condensate might appear at outlet grill.

3-min delay protection

Unit will not restart until 3 min have elapsed for the protection of the unit.

Fan speed changes

When Fan speed is set at Auto in cooling mode, it will be automatically reduced as room temp. is approaching temp. setting. In dry mode, fan speed will change automatically.

Cold draft prevention

In heating mode, indoor fan will not run for the first 2-5 min. due to cold draft prevention.

Defrosting

When frost accumulates on heat exchanger in heating mode, unit will start defrosting automatically. During defrosting, both indoor and outdoor fan stop. After defrosting, unit resumes running.

Use objectively

Heat pump works by means of absorbing outside heat to warm room air, so outdoor temp. degree will affect unit's heating efficiency.

Energy saving

Keep proper room temp.

Too cold or too warm is no good to your health, and power consumption will be increased as well.

Air filter should be periodically cleaned

If air filter is clogged:

It will cause poor cooling and heating efficiency, higher power consumption and even problem may occur. In cooling operation, water will flow out.

Use Timer effectively

You may use Timer mode to keep a comfortable room temp.when

Don't spray any paint or insecticide on the unit.

This will cause damage or even fire accident.

Air filter cleaning

Don't wash with hot water or solvent to clean the unit

Pull it out from top as shown in Fig.

Use water or vacuum cleaner to clean it. If it is extremely dirty, wash it with neutral detergent or soap water.

Wash it with clean water and install it after complete dry.

Caution:

Don't use hot water over 40 C, as this may cause damage to air filter. Wipe air filter carefully.

Maintenance

Indoor and outdoor cleaning

Clean it with warm and wet cloth or with neutral detergent, then wipe it dry with clean and soft cloth. If air conditioner is very dirty, clean it with cloth soaked in neutral detergent,then wipe off the detergent with clean water. Don't use water higher than 40 C , which will cause discoloring and deformation. Don't use insecticide or other chemical detergents.

After season maintenance

Let the unit run in Fan mode for half a day in a fine weather to dry completely the unit inside.

Turn off the unit and pull out power plug.

There might be certain power consumption even if unit is stopped.

Clean air filter and indoor unit, cover outdoor unit after cleaning.

Before season maintenance

Check if there are obstacles at inlet and outlet of indoor and outdoor unit, whick will reduce unit efficiency.

Don't fail to attach air filter after making sure it is cleaned. Dust will enter into unit causing damages or faults if it is running without air filter.

To protect compressor at start, please connect external power supply to the unit 12 hrs prior to starting. Also please keep the power supply switch ON during the whole season.

Trouble shooting

Followings are not problems

Sound of water flowings are not problems.

Sound of cracking is heard.

Smells are generated.

During operation, white fog or steam comes out of indoor unit.

In cooling operation, unit switches to fan operation.

Unit will not restart after stop. Won't start?

During unit start and operation or at stop, a swishing or gurgling noise may be heard. 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 temperatuer changes.

This is because the system circulates smells from the interior air such as the smell of cigarettes or the painting on the unit.

When unit is running at places like restaurant where dense edible oil fumeis always exist, this will happen.

To prevent frost from accumulating on indoor heat exchanger, unit will switch to fan operation for a while then resume cooling operation.

Though ON/OFF button is set to ON, unit won't resume cooling,dry or heating operation in 3 min after it is stopped, this is because of 3min-delay protection circuit.

No outlet air or fan speed can't be changed in dry mode.

In heating operation, water or steam are blown out of indoor unit.

In heating operation, indoor fan won't stop even if unit is stopped.

Please wait 3 minutes

Unit will reduce fan speed repeatedly and automatically if room temp. is too low in dry operation.

This occurs when frost accumulated on the outdoor unit is removed. (during defrosting operation)

After unit stops, indoor fan will go on running until indoor unit cools down.

When problems occur

Before asking services, please firstly check your unit according to following.

Air conditioner won't start.

4.Purging method

Discharge the air out of the indoor unit and the refrigerant pipe by vacuumizing (1) Fasten all the nuts of the indoor and outdoor pipes to make these parts out of leakage.

(2) Under the condition of the complete close of the indoor and outdoor valve center (both

liquid and gas side),dismount the repair valve cap.Vacuumizing through the charge mouth of the repair valve.

(3) After vacuumizing fasten the repair valve,and dismount the cap of the big and small

stop valve,then loosen the stop valve center completely and fasten the big and small

stop valve.

5.Extra charging amount of the refrigerant

When piping is longer than 5 m, charge additional refrigerant specified in this list.
