12. Installation, relocation and inspection

Installation place
Avoid installing the air conditioner in the following places.
• Where flammable gas could leak.
Caution:
Do not install the unit where flammable gas could leak.
If gas leaks and collects around the unit, it may cause an explosion.
• 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 but does not cool or heat (depending
on model) the room, consult your dealer since there may be a refriger-
ant 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 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:
• 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.
• Install an earth leakage breaker depending on the place where the air conditioner is to be installed (humid place, etc.).
If the earth 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 lowered 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.
