*Be sure to add the proper amount of additionalrefrigerant. Failure to do so may result inreduced performance.

Remark: The refrigerant pre-charged in theoutdoor unit is for piping length up to7.5 m.

Piping Works• Do not use contaminated or damaged copper

tubing. Do not remove plastic, rubber plugsand brass nuts from the valves, fittings, tubingsand coils until you are ready to connect suctionor liquid line into valves or fittings.

• If any brazing work is required, ensure thatthe nitrogen gas is passed through coil andjoints while the brazing work is being done.This will eliminate soot formation on theinside walls of the copper tubings.

• Cut the connection pipe with a pipe cutter.• Remove burrs from cut edges of the pipes with

remover.Hold the end of the pipe downwards to preventmetal chips from entering the pipe.

• Insert the flare nuts, mounted on theconnection parts of both the indoor unit andoutdoor unit onto the copper pipes.

• Flare the pipe with extra length above theflaring tool as shown in the table.

• The flared edge must be even and not crackedor scratched.

VACUUMING AND CHARGING

Purging The Piping And The Indoor UnitExcept for the outdoor unit which is pre-chargedwith refrigerant, the indoor unit and therefrigerant connection pipes must be air-purgedbecause the air containing moisture that remainsin the refrigerant cycle may cause malfunctionof the compressor.• Remove the caps from the valve and the

service port.• Connect the center of the charging gauge to

the vacuum pump.• Connect the charging gauge to the service

port of the 3-way valve.• Start the vacuum pump. Evacuate for

approximately 30 minutes. The evacuationtime varies with different vacuum pumpcapacity. Confirm that the charging gaugeneedle has moved towards -760mmHg.

Caution• If the gauge needle does not move to

-760mmHg, be sure to check for gas leaks(using the refrigerant detector) at flare typeconnection of the indoor and outdoor unitand repair the leak before proceeding to thenext step.

AIR CONDITIONER UNIT OPERATION

Dry Mode• When the air humidity is high, the unit can

operate in dry mode. Press <MODE> buttonand choose <DRY>.

• If the room temperature is 2°C/3.6°F higherthan the set temperature, the air conditionerwill operate under cooling mode until itreaches within the 2°C/3.6°F range ofdifference compared to the set temperaturebefore it converts to dry mode.

• If the room temperature is within the 2°C/3.6°F range of difference compared to theset temperature, it will directly operate underdry mode.

• The unit will operate at LOW speed underdry mode.

Air Flow Control• For more effective air circulation, you can

manually adjust the air discharge grille tothe left or right.

• During cool mode operation and dry modeoperation, do not direct the air dischargelouver downwards for too long. If operatingcontinues in this way, condensation mayoccur on the louver, thus resulting indrippings.

Frost Prevention• When the air filter is dirty, the evaporating

temperature will decrease and eventuallycause frosting.

• If the evaporating temperature reaches-1°C/33.8°F, the unit will trip.

Fan Speed And Rated Cooling Capacity• The rated cooling capacity is provided at the

high fan speed.• The cooling capacity is lower when the unit

is operating at MEDIUM and LOW fanspeed.

Notes On Flaps And Louvers Angles• When “SWING button” is selected, the flaps

swinging range depends on the operationmode. (See the figure.)

ATTENTION• Always use a remote controller to adjust the

flaps angle. If you attempt to move it forciblywith hand when it is swinging, themechanism may be broken.

• Be careful when adjusting the louvers. Insidethe air outlet, a fan is rotating at a high speed.
