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. 4 DESCRIPTION OF AIR CONDITIONER INDOOR UNIT Drain Pipe To drain water produced while the unit is functioning Indicator light state 1.

A thin fog may flow from the outlet when the air conditioner is running in cooling mode. You may hear a slight crack when the air conditioner is started or stopped. Air conditioner does not run. The air conditioner is not cooling (or heating) properly. Remote control cannot execute control. Water leaks from indoor unit. Water leaks from outdoor unit. Cause • To protect the air conditioner when started after a stop, the microcomputer control delays for 3 minutes before allowing the air conditioner to start. • 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). • When the air conditioner is started, or the compressor starts or stops while running, or the air conditioner is stopped, you may hear a gurgling noise that is the refrigerant flowing back and is not a malfunction. • This may occur when the indoor temperature and humidity are high. This is because the indoor air is cooled quickly. • After a short time, the fog will disappear as the indoor temperature and humidity decrease. • This is the sound of friction caused by expansion of the front panel or other parts due to the change of temperature • • • • • • • • • • • • • • • • • • • • • Is there a power failure? Is the power plug loose in the socket? Has the circuit protection device been tripped? Is the voltage too high or too low? (have it tested by a professional). Has the timer function been used correctly? Is the temperature setting correctly? Is the air intake or outlet of the outdoor unit blocked? Is the air filter clogged by dust (see Cleaning and Maintenance)? Are all the doors and windows closed Is the air flow set to "LOW FAN"? Is there another heat source in the room? The remote control sometimes cannot execute control if the air conditioner is subject to abnormal interference or frequent switch of functions. To resume normal operation, switch off and on again properly. Is the remote control in range and not blocked by any obstacles? Check the battery in the remote control. If low, replace the battery. Check the remote control for damage. High air humidity. Condensation overflow. Joint of indoor unit drain pipe is loose. In cooling mode, water may condense on pipe or pipe joint due to cooling. Defrost water flows out in heating or defrost (auto defrost) mode. In cooling mode, water from heat exchanger may leak. 21 Malfunction Indoor unit makes noise. Cause • The sound comes from the fan or compressor relay switching over (close/open). • Air conditioner may make noise in defrost mode or when stopped due to inverse flow of refrigerant in the unit. Moisture on outlet grill • If the air conditioner is left running in high humidity, moisture may condense on the grill and accumulate there.
