1) Outdoor unit
Warning:
• The outdoor unit must be installed on a stable, level surface, in a place
where there is no accumulation of snow, leaves or rubbish.
• Do not stand on, or place any items on the unit. You may fall down or the
item may fall, causing injury.
Caution:
The outdoor unit should be installed in a location where air and noise emitted by the unit will not disturb the neighbours.
2) Indoor unit
Warning:
The indoor unit should be securely installed. If the unit is loosely mounted, it
may fall, causing injury.
3) Remote controller
Warning:
The remote controller should be installed in such a way that children cannot
play with it.
4) Drain hose
Caution:
Make sure that the drain hose is installed so that drainage can go ahead
smoothly. Incorrect installation may result in water leakage, causing damage to furniture.
5) Power line, fuse or circuit breaker
Warning:
• Make sure that the unit is powered by a dedicated line. Other appliances
connected to the same line could cause an overload.
• Make sure that there is a main power switch.
• Be sure to adhere to the unit’s voltage and fuse or circuit breaker ratings.
Never use a piece of wire or a fuse with a higher rating than the one
specified.
6) Grounding
Caution:
• The unit must be properly grounded. Never connect the grounding wire
to a gas pipe, water pipe, lightning conductor or telephone grounding
wire. If the unit is not grounded properly, electric shock may result.
• Check frequently that the ground wire from the outdoor unit is properly
connected to both the unit’s ground terminal and the grounding electrode.

1.2. During operation
Caution:
• Do not use any sharp object to push the buttons, as this may damage the
remote controller.
• Do not twist or tug on the remote controller cord as this may damage the
remote controller and cause malfunction.
• Never remove the upper case of the remote controller. It is dangerous to
remove the upper case of the remote controller and touch the printed
circuit boards inside. Doing so can result in fire and failure.
• Never wipe the remote controller with benzene, thinner, chemical rags,
etc. Doing so can result in discoloration and failure. To remove heavy
stains, soak a cloth in neutral detergent mixed with water, wring it out
thoroughly, wipe the stains off, and wipe again with a dry cloth.
• Never block or cover the indoor or outdoor unit’s intakes or outlets. Tall
items of furniture underneath the indoor unit, or bulky items such as
large boxes placed close to the outdoor unit will reduce the unit’s efficiency.
Warning:
• Do not splash water over the unit and do not touch the unit with wet
hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance where it will
be exposed to the air discharged from the unit. Incomplete combustion
may result.

Warning:
• Do not remove the front panel or the fan guard from the outdoor unit
when it is running. You could be injured if you touch rotating, hot or highvoltage parts.

closed room for a long period of time, the air will become stale.
In case of failure
Warning:
• Never remodel the air conditioner. Consult your dealer for any repair service. Improper repair work can result in water leakage, electric shock, fire,
etc.
• If the remote controller displays an error indication, the air conditioner
does not run, or there is any abnormality, stop operation and contact
your dealer. Leaving the unit as it is under such conditions can result in
fire or failure.
• If the power breaker is frequently activated, get in touch with your dealer.
Leaving it as it is can result in fire or failure.
• If the refrigeration gas blows out or leaks, stop the operation of the air
conditioner, thoroughly ventilate the room, and contact your dealer. Leaving the unit as it is can result in accidents due to oxygen deficiency.
When the air conditioner is not to be used for a long
time
• If the air conditioner is not to be used for a long time due to a seasonal
change, etc., run it for 4 - 5 hours with the air blowing until the inside is
completely dry. Failing to do so can result in the growth of unhygienic,
unhealthy mold in scattered areas throughout the room.
• When it is not to be used for an extended time, keep the [power supply]
turned OFF.
If the power supply is kept on, several watts or several tens of watts will
be wasted. Also, the accumulation of dust, etc., can result in fire.
• Keep the power switched ON for more than 12 hours before starting operation. Do not turn the power supply OFF during seasons of heavy use.
Doing so can result in failure.
1.3. Disposing of the unit
