PRECAUTIONS FOR USE
Warning:
• Make sure to insert the power plug securely. Insecure insertion of the plug may cause electrocution or fire.
• Never unplug the machine while running.
• Do not damage the cord or use an unapproved cord.
• Do not plug other electric appliances into the same socket or use extension cords.
• Never operate the air conditioner with wet hands.
• Do not pull the plug out by the cord. This could cause the cord to overheat and catch fire.
• Turn off the air conditioner and pull out the plug when cleaning the air conditioner. This will prevent electrocution
or injury.
• The rated voltage of this air conditioner is 220-240V 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 Center 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.
• Make sure to unplug air conditioner when not in use for an extended period. Accumulation of dust could cause
heating or fire.
• 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 Center nearest you for repairs.
• Adjust the air flow and direction properly. When the air conditioner is running, you can adjust the air flow direction
by setting the upper/lower guide louver position using the remote control or handle.
• 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.

Warning:
• Do not cut or damage the power cords and control lines. Any damaged power cords and signal control lines of the
air conditioner must be replaced by qualified technicians with special cords.
• 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.

INSTRUCTIONS FOR USE
The Principle and Special Functions of Cooling Mode
Principle:
The air conditioner absorbs heat from indoor air and discharges it
outdoors, thus lowering the indoor room temperature. Cooling
capacity decreases with a rise in outdoor temperatures.
Anti-freeze Function:
Frost may appear on the surface of the indoor heat exchanger if the
air conditioner is running under low-temperature cooling mode.
When the temperature of the indoor heat exchanger drops to 0° or
below the outdoor unit microcomputer will bring the compressor to
a standstill to protect the complete unit.
The Principle and Special Functions of the Heating
Mode
Principle:
• The air conditioner absorbs heat from outdoor air to transmit
indoors thus increasing the room temperature. Heating capacity
decreases with a reduction in outdoor temperatures.
• This type of hot air circulating system can increase indoor
temperatures very quickly.
• Use this air conditioner with other heating equipment when
outdoor temperatures are extremely low.
Defrost:
• The outdoor unit heat exchanger may frost when the outdoor
temperature is low, humidity is high and the air conditioner has
been running for some time, resulting in inefficient heating. In this
case, the appliance automatically defrosts and heating is
suspended for 6/8-10 minutes.
• Both the indoor fan and outdoor fan are brought to a standstill
during auto defrost.
• An indicator light on the indoor unit flashes and mist might flow
from the indoor unit during defrost. This is a result of rapid
defrosting and is quite normal.
• Heating mode is automatically resumed on completion of defrost
process.
Possible causes of failure of the air conditioner to function
A safety device may be activated in the temperature range as
specified below, so that the unit might be stopped.
