●

Please read the “Safety Precaution” carefully before operating the unit to ensure correct usage of the unit.

●

Pay special attention to signs of “ Warning” and “ Caution”. The “Warning” section contains matters which,

if not observed strictly, may cause death or serious injury. The “Caution” section contains matters which may

result in serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.

●

The sign indicate the following meanings.

●

Please keep this manual after reading.

WARNING

PRECAUTIONS DURING INSTALLATION

●

Do not reconstruct the unit.

Water leakage, fault, short circuit or fire may occur if you reconstruct the

unit by yourself.

●

Please ask your sales agent or qualified technician for the installation of

your unit. Water leakage, short circuit or fire may occur if you install the unit

by yourself.

●

Please use earth line.

Do not place the earth line near water or gas pipes, lightning-conductor, or

the earth line of telephone. Improper installation of earth line may cause

electric shock.

●

A circuit breaker should be installed depending on the mounting site of the

unit. Without a circuit breaker, the danger of electric shock exists.

●

Do not install near location where there is flammable gas. The outdoor unit

may catch fire if flammable gas leaks around it.

●

Please ensure smooth flow of water when installing the drain hose.

PRECAUTIONS DURING OPERATION

●

Do not attempt to operate the unit with wet hands, this could cause fatal

accident.

●

When operating the unit with burning equipments, regularly ventilate the

room to avoid oxygen insufficiency.

●

Do not direct the cool air coming out from the air-conditioner panel to face

household heating apparatus as this may affect the working of apparatus

such as the electric kettle, oven etc.

●

Do not place plants directly under the air flow as it is bad for the plants.

●

Please ensure that outdoor mounting frame is always stable, firm and

without defect. If not, the outdoor unit may collapse and cause danger.

●

Do not splash or direct water to the body of the unit when cleaning it as this

may cause short circuit.

●

When operating the unit with the door and windows opened, (the room humidity is always above

80%) and with the air deflector facing down or moving automatically for a long period of time,

water will condense on the air deflector and drips down occasionally. This will wet your furniture.

Therefore, do not operate under such condition for a long time.

●

If the amount of heat in the room is above the cooling or heating capability of the unit (for

example: more people entering the room, using heating equipments and etc.), the preset room

temperature cannot be achieved.

●

This appliance is not intended for use by young children or infirm persons unless they have been

adequately supervised by a responsible person to ensure that they can use the appliance safely.

●

Young children should be supervised to ensure that they do not play with the appliance.

●

Do not climb on the outdoor unit or put objects on it.

●

Please switch off the unit and turn off the circuit breaker during cleaning, the

high-speed fan inside the unit may cause danger.

●

Turn off the circuit breaker if the unit is not to be operated for a long period.

!

●

The product shall be operated under the manufacturer specification and

not for any other intended use.

●

Do not put water container (like vase) on the indoor unit to avoid water

dripping into the unit. Dripping water will damage the insulator inside the unit

and causes short-circuit.

●

Do not use any aerosol or hair sprays near the indoor unit. This chemical

can adhere on heat exchanger fin and blocked the evaporation water flow

to drain pan. The water will drop on tangential fan and cause water splashing

out from indoor unit.

MODEL NAME AND DIMENSIONS

MULTI-AIR CONDITIONER

With this multi-air conditioner, several indoor units can be connected to one outdoor unit to be driven. You can operate

the required number of indoor units.

Combination of Operations:

● You cannot operate the indoor units in the

following combinations.

● The indoor unit which is switched on first continues to

operate, but other indoor units which is switched on later

does not operate while the lamp lights.

● To re-start an indoor unit which was operated later, stop

the indoor unit which was operated first or later and reset

the type of operation, then perform operation again.

Other unit

Cooling

Dehumidifying

Circulating (fan)

Adjusting the Number of Indoor Units:

Decrease the number of indoor

units to be operated especially

when it is very hot or cold or

when you want to reach the

present temperature quickly.

Stopped Indoor Units:

When an indoor unit is operated in the cooling,

heating or dehumidifying mode in the room, the

sound of refrigerant flow may be heard from a

stopped indoor unit or a stopped indoor unit may

become warm. This is because the indoor unit

returns refrigerant to the outdoor unit to be ready

for operation.

When operation mode is selected:

● When heating operation is automatically selected for the first indoor unit, the next indoor unit will then start to heat.

Also, if cooling or dehumidifying is automatically selected for the first indoor unit, the next indoor unit will also start

to cool or dehumidify.

During automatic operation:

not change when indoor unit connected to multi type outdoor unit.

■ As the settings are stored in memory in the remote controller, you only have to press the

(START/STOP) button next time.

Press the FUNCTION selector so that the display indicates the (AUTO) mode of operation.

● When AUTO has been selected, the device will automatically determine the mode of

operation, HEAT, COOL or DEHUMIDIFY depending on the current room temperature.

However the mode of operation will not change when indoor unit connected to multi type

outdoor unit.

● If the mode automatically selected by the unit is not satisfactory, manually change the

mode setting (heat, dehumidify, cool or fan).

Press the (START/STOP) button.

Operation starts with a beep.

Press the button again to stop operation.

You can raise or lower the temperature setting as necessary by maximum of 3°C.

Press the temperature button and the temperature setting will change by

1°C each time.

● The preset temperature and the actual room temperature may vary somewhat depending on

conditions.

● The display does not indicate the preset temperature in the AUTO mode. If you change the

setting, the indoor unit will produce a beep.
