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

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.

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.

• 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.
