Installation Area
Avoid installing the air conditioner in the following places.
• Where flammable gas could leak.
Caution:
Do not install the unit in an area where flammable gas could leak.
If gas leaks and collects around the unit, it may cause an explosion.
• Where there is a lot of machine oil in the atmosphere.
• Salty place such as the seaside.
• Where sulfide gas is generated such as a hot spring.
• Where there is oil splashing or much oily smoke in the atomosphere.
Warning:
If the air conditioner operates but does not cool or heat (depending
on model) the room, consult your dealer since there may be a refrig-
erant leak. Be sure to ask the service representative whether there is
refrigerant leakage or not when repairs are performed.
The refrigerant charged in the air conditioner is safe. Refrigerant nor-
mally does not leak, however, if refrigerant gas leaks indoors, and
comes into contact with the fire of a fan heater, space heater, stove,
etc., harmful substances will be generated.
10. Troubleshooting
Troubleshooting Solution
Operating sound is louder than specifications.
Nothing appears in the wireless remote controller display, the display is
faint, or signals are not received by the indoor unit unless the remote con-
troller is close.
The operation lamp near the receiver for the wireless remote controller on
the indoor unit is flashing.
■ The indoor operation sound level is affected by the acoustics of the par-
ticular room as shown in the following table and will be higher than the
sound specification, which was measured in an echo-free room.
■ The batteries are low.
Replace the batteries and press the Reset button.
■ If nothing appears even after the batteries are replaced, make sure that
the batteries are installed in the correct directions (+, –).
■ The self diagnosis function has operated to protect the air conditioner.
■ Do not attempt to repair this equipment by yourself.
Turn off the power switch immediately and consult your dealer. Be sure
to provide the dealer with the model name.

11. Installation, relocation and inspection
Electrical work
• Provide an exclusive circuit for power supply of the air conditioner.
• Be sure to observe the breaker capacity.
Warning:
• The customer should not install this unit. If the unit is installed incorrectly, fire, electric shock, injury, water leakage, etc. may result.
• Do not connect using branched outlet or an extension cord, and do not attach many loads to one electric outlet.
A fire or electric shock may result from poor contact, poor insulation, exceeding the permissible current, etc.
Consult your dealer.
Caution:
• Include a ground wire.
Do not connect a ground wire to a gas pipe, water pipe, lightning rod or ground wire of a telephone.
If a ground is incorrect, it may cause an electric shock.
• Install a ground leakage breaker depending on the place where the air conditioner is to be installed (humid place, etc.).
If the ground leakage breaker is not installed, it may cause an electric shock.
Inspection and maintenance
• When the air conditioner is used for several seasons, the capacity may be reduced due to dirt inside the unit.
• Depending upon the conditions of use, an odor may be generated or dirt, dust, etc. may prevent proper drainage.
• It is recommended to apply inspection and maintenance (charged) by a specialist in addition to normal maintenance. Consult your dealer.
