Operation hints

Cleaning of the unit

Turn off the power switch Do not touch with wet hand

Do not clean with hot water or solvent

Take off the air inlet grill

First switch off the power supply, take off the screw cap, loosen the screw with cross screwdriver.

Clean the filter

Caution:

Clean the indoor(outdoor) unit Clean with warm cloth or neutral detergent,

then wipe away moisture with dry cloth. Do not use too hot water(above 40oC), which will cause discoloration or deformation. Do not use pesticide or other chemical detergents.

Do not wash filter in hot water above 40oC, which will damage the filter. Do carefully wipe the filter.

Use water or vacuum cleaner to remove dust. If it is too dirt, clean with detergent or neutral soap water. Rinsing with fresh water, dry the filter and re-assemble.

Maintenance

Maintenance at the end of application season

Clean the filter and indoor, outdoor unit, cover the units well.

Maintenance before beginning of application season

Check there are no obstacles in the air inlet and outlet to avoid impairing of working efficiency.

Please do attach the air filter to ensure the electrostatic filters not soiled. Otherwise,dirt will come into and damage the unit or bring failures.

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

Turn off the unit operation switch and power on/off. Otherwise, there will be some electricity consumption even the unit is in stop status.

Maintenance

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?

Cause or check points

Phenomenon

The system does not restart immediately

Noise is heard:

Smells are generated.

Mist or steam are blown out

Does not work at all.

Multiple chec

Normal Performance inspection

Poor cooling

Before asking for service, check the following first.

When unit is stopped, it won't restart immediately until 3 min

utes 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 ma

y 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 ma

y blow out mist. This is due to the sudden

cooling of indoor air.

Is power plug inserted? Is there a power failure? Is fuse blown out?

Installation Manual of Room Air Conditioner

Installation of indoor unit

selection of installation place Place where it is easy to route drainage pipe and outdoor piping. Place, away from heat source and with less direct sunlight. Place where cool and warm air could be delivered evently to every corner of the room. Place near power supply socket.Leave enough space around the unit. Place, robust not causing vibration, where the body can be supported sufficiently.

Installation of outdoor unit

selection of installation place Place strong enough to support the unit and will not cause vibration and noise. Place where discharged wind and noise does not cause a nuisance to the neighbors. Place where is less affected by rain or direct sunlight and is sufficiently ventilated,or to install a shield. Place with enough space for smooth air flow.

Piping connection of the indoor unit

1. Arrangement of piping and drainage pipe Remove the cover before working.

Cut away, with a hammer or a saw, the lid for piping according to piping direction.

3. Piping connection

Connecting method

Apply refrigerant oil at half union and flare nut. To bent a pipe, give the roundness as large as possible not to crash the pipe.

Be careful not to let foreign matters, such as sands enter the pipe.

When connecting pipe, hold the pipe center to center then screw nut on by hand, refer to Fig.

2. Arrangement drain hose Drain hose shall be placed in under place.

There should be a slope when arrange drain hose. Avoid up and down waves in drain hose. If humidity is high, drain pipe(especially in room and indoor unit) must be covered with installation material.

Insert the bound piping connecting electric cable and drain hose through wall hole to connect

together with polyethylene tape.

acuum pump. If the scale-moves of gause (low) reach vacuum condition in a moment, check again.

Vacuumize for over 15min. And check the level gauge which should read -0.1 MP

a (-76 cm Hg) at low pressure side. After the completion of vacuumizing, close the handle 'Lo' in gaugemanifold and stop the operation of the vacuum pump. Check the condition of the scale and hold it for 1-2min. If the scale-moves back in spite of tightening, make flaring work again, the return to the beginning of

Open the valve rod for the 2-way valve to an angle of anticloc

No gas leakage?

In case of gas leakage, tighten par

ts of pipe connection. If leakage stops, then proceed steps.

Detach the charge hose from the service port, open 2-w

ay valve and 3-way. Turn the valve rod anticlockwise

until hitting lightly.

To prevent the gas leakage, turn the service port's cap

After attaching the each caps, check the gas leakage around the caps

CAUTION:

1.If the refr

igerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the name plate.

2.Please do not let other cooling medium, except specified one (R410A), or air enter into the cooling circulation system.

Otherwise, there will be abnormal high pressure in the system to make it crack and lead to personal injuries.

If it does not stop gas leakage, discharge whole refr

igerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder

Wiring of indoor unit

Replace cover after wiring.

Pull it out from front. Pull the cable gently to make sure it is tight.

Insert the cable from outside the wall hole where piping already exist. Loose terminal screw and insert cable end fully into terminal block, then tighten it

Note: When additional refrigerant is necessary, first purge air out of connecting pipe by external gas, then drive out the excessive refrigerant by purging method.. Brand new unit is charged 80g more refrigerant than spec. This is only for first installation to purge air in the indoor unit and connecting pipe. When piping is longer than 5m, change additional refrigerant specified in this list.

Pull the cable gently to make sure it is tight. Replace cover after wiring.

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 control or cause operation failure.

Electric wiring Note:

Electric wiring must be done by qualified person. Use copper wire only. The parameter of the connecting cable is H05RN-F or H07RN-F
