●

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.

Make sure to connect earth line.

Indicates the instructions that must be followed.

●

Please keep this manual after reading.

PRECAUTIONS DURING INSTALLATION

●

Do not reconstruct the unit. Water leakage, fault, short circuit or fire may occur if you reconstruct the unit by yourself.

●

WARNING

CAUTION

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.

The sign in the figure indicates prohibition.

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

●

Should abnormal situation arises (like burning smell), please stop operating the unit and turn off the circuit breaker. Contact your agent. Fault, short circuit or fire may

occur if you continue to operate the unit under abnormal situation.

●

Please contact your agent for maintenance. Improper self maintenance may cause

electric shock and fire.

●

Please contact your agent if you need to remove and reinstall the unit. Electric

shock or fire may occur if you remove and reinstall the unit yourself improperly.

PRECAUTIONS DURING OPERATION

●

Avoid an extended period of direct air flow for your health.

A R N

●

Do not use any conductor as fuse wire, this could cause fatal accident.

I N G

EN1-RAS-5111CS/RAC-5111C 16/11/05, 4:15 PM2

●

Do not put objects like thin rods into the panel of blower and suction side because the high-speed fan inside may cause danger.

●

During thunder storm, disconnect and turn off the circuit breaker.

– 2 –

PRECAUTIONS DURING OPERATION

●

The product shall be operated under the manufacturer specification and not for any other intended use.

●

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.

●

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.

●

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.

C A U T

I O N

●

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

●

Please switch off the unit and turn off the circuit breaker during cleaning, the high-speed fan inside the unit may cause danger.

ENGLISH

●

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.

●

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.

EN1-RAS-5111CS/RAC-5111C 16/11/05, 4:15 PM3

●

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

●

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

ADJUSTING THE AIR DEFLECTOR

Adjustment of the conditioned air in the upward and downward

directions. According to “Dehumidifying” or “Cooling” operation, the horizontal air deflector is automatically set to the proper angle suitable for each operation. The deflector can be swung up and down and also set to the desired angle using the “ (AUTO SWING)” button. (If the angle of the deflector is changed, it will not return to the auto-set position after operations start unless the operation mode is switched.)

● If the “ (AUTO SWING)” button is pressed once, the

horizontal air deflector swings up and down. If the button is pressed again, the deflector stops in its current position. Several seconds (about 6 seconds) may be required before the deflector starts to move.

● In “Cooling” operation, do not keep the horizontal air

deflector swinging for a long time. Some dew may form on the horizontal air deflector and dew may drop.

Adjustment of the conditioned air to the left and right.

Hold the vertical air deflector as shown in the figure and adjust the conditioned air to the left and right.
