PRECAUTIONS FOR USE

Warning:

• Never operate the air conditioner with wet hands.

• The rated voltage of this air conditioner is 220240V with a tolerance of ±22V for fluctuation. The compressor will vibrate if the voltage is too low, causing damage to the cooling system.

• If you notice anything unusual (e.g. burnt smell), switch off the power supply immediately and contact the Whirlpool Authorized Service Centre nearest you. If the abnormal condition continues, the air conditioner could be damaged and could also cause electrocution or fire.

• Grounding: The unit must be reliably grounded. The grounding cable must be connected to the special grounding system in the building. If the building does not have a grounding system, ask an expert electrician to install one. Never connect the grounding cable to a gas pipe, water pipe, sewage pipe or other unless the professional considers it reliable.

• Set the room temperature appropriately. The difference between indoor and outdoor temperature should be 5°C. Appropriate adjustment of the temperature setting serves to reduce consumption.

• When the air conditioner is running, do not leave doors and windows open in the room. This will prevent loss of effectiveness of the air conditioner.

• Never block the air inlet or outlet of indoor and outdoor unit, as this will decrease the effect of the air conditioner or cause it to shut down or even catch fire.

• Spray cans, chemicals and gas tanks must be placed at least 1m away from the indoor and outdoor unit; they could cause fire or explosion

• Make sure to mount the outdoor unit on a sturdy base. If the base is damaged and unsteady, the unit could fall and cause injury.

• Do not stand or place anything on the outdoor unit. Persons or objects falling from the unit could cause injuries.

• Do not repair the air conditioner yourself. Incorrect repairs could cause electrocution or fire. Contact the Whirlpool Authorized Service Centre nearest you for repairs.

• Never reach with your finger or a stick into the indoor or outdoor unit.

• Never blow the air directly at pets or plants, as this may harm them.

• Never spray water onto the unit or wash the air conditioner with water.

• Never let the air conditioner blow on a heat source. This could put the flame out and cause carbon monoxide poisoning.

• To avoid any harm to your health, do not blow the cold air on your body too long or lower the room temperature too much.

• This air conditioner cannot be used for drying clothes or chilling foods.

• Do not spray any paint or pesticide on the unit, or it may cause fire.

Warning:

• Persistent abnormality indicates that the air conditioner may be damaged with the consequent risk of electric shock or fire. This may cause an electric shock.

• To prevent fire always use a special power supply circuit.

• Disconnect the air conditioner from the power supply if it is to be left unused for a long period.

• For 18-23K, 230V, with a tolerable fluctuation of ±23V. The compressor is subject to strong vibrations under very low voltages which can damage the refrigerating system. Electrical elements are easily damaged by high voltage.

• Ensure that the power supply is suitably protected by a special circuit with air breaker. The air conditioner automatically starts or stops according to requirements. Do not switch the air conditioner on and off too often as this can damage the appliance. This may cause an electric shock or injury.

• Do not cut or damage the external cable. Any damaged external cable must be replaced by qualified electricians.

TROUBLESHOOTING

Malfunction Cause

Air conditioner does not start immediately after a stop.

• To protect the air conditioner when started after a stop, the microcomputer control delays for 3 minutes before allowing the air conditioner to start.

An unpleasant odour is perceived at start-up.

• The air conditioner itself is odourless. Any odour is accumulated from the environment. The solution is to clean the air filter (see Cleaning and Maintenance).

• If there is still any problem, the air conditioner should be cleaned (Please contact the Whirlpool Authorized Service Centre).
