Whirlpool AMD 383 Instruction for Use
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
Warning:
Do not attempt to repair the air conditioner yourself. Incorrect repairs may cause electrocution or
fire, so please contact the Whirlpool Authorized Service Centre nearest you for professional repairs.
The following checks may save your time and costs.
Malfunction
Air conditioner does not
start immediately after a
stop.
An unpleasant odour is
perceived at start-up.
You may hear a "gurgling"
noise when the air
conditioner is on.
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
