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 heating mode. when room temp. reaches temp. setting, compressor will stop and fan speed LOW or stop. 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.

Proper temp.

Use Timer effectively

You may use Timer mode to keep a comfortable room temp. when you wake up or come home from outside.

Avoid direct sunlight and air flow

OFF

Keep a smooth air flow to inlet and outlet of both indoor and outdoor unit.

To avoid accident, don't insert any object into air grill.

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

Use fuses of the right capacity. Never use iron or copper wires instead.

Don't touch moving outlet grills.

This will cause damage or even fire accident.

Don't splash water directly on indoor unit.

This could be very dangerous

Maintenance

Disconnect power supply

Don't touch it with wet hand

Air filter cleaning

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.

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

Caution:

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

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.

Maintenance

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 3-min-delay protection circuit.

Please wait 3 minutes

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.

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 ask for services, please first check your unit against following.

Air conditioner won't start.

Is power supply switch turned on?

Is city power supply normal?

Is leakage current breaker activated?

Power supply switch is not set at ON.

Are operation controlls adjusted correctly as specified?

Proper temp

Are horizontal louvers at up position (in heating mode)?

Is there any direct sunlight in the room?

Power failure?

Poor cooling or heating

Is air filter too dirty?

Any doors or windows left open?

Poor cooling

If there are unexpected heat sources in the room?

This is very dangerous, please disconnect power supply immediately and contact your dealer.

Are there any obstacles at inlet or outlet grill?

Too many people in the room?

If your unit still can't work properly after above mentioned checks, or following problems occur, please stop it immediately and contact your dealer. Fuses or circuit breakers often blow out. Water comes out in cooling/dry operation. Operation is abnormal or sound is heard.

If the fuse on PC board is broken please change it with the type of 50F.3.15A/250V.

Terminal block (outdoor)

Note:

When connecting indoor and outdoor wire, check the number on indoor and outdoor terminal blocks. Terminals of same number and same color shall be connected by the same wire. Incorrect wiring may damage air conditioner's controller or cause operation failure.

Others

1. Power supply

Air conditioner must use an exclusive line (over 30A) When installation air conditioner in a wet place, try to use a circuit breaker against Current leakage. For installation in other places, use circuit breaker as far as possible.

The breaker of the air conditioner should be all-pole switch ; and the distance between its two contacts should be no less 3 mm.

Such means for disconnection must be incorporation in the fixed wiring

2. Pipe cutting and flaring

Be sure to carry out deburring after pipe cutting with a pipe cutter. Insert flaring tool to make a flare.
