Installation place
Avoid installing the air conditioner in the following places.

Caution:
Do not install the unit where flammable gas could leak.
If gas leaks and collects around the unit, it may cause an ex plosion.
• Where there is much machine oil.
• 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.
Warning:
If the air conditioner operates b ut does not cool or heat ( depending on
model) the room, consult your dealer since there may b e a refrigerant
leak. Be sure to ask the service representative whether there is
refrigerant leakage or not when repairs are carried out.
The refrigerant charged in the air conditioner is safe. Refrigerant
normally 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.
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 due to a falling unit, water leakage, etc.
may result.
• Do not connect using b ranched outlet or an ex tension 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.

• Apply grounding
Do not connect a grounding wire to a gas pipe, water pipe, lightning rod or ground wire of a telephone.
If a grounding is incorrect, it may cause an electric shock.
