INSTALLATION, RELOCATION AND INSPECTION
CAUTION:
• Earth the unit.
Do not connect the earth to a gas pipe, water pipe, lightning rod or the earth of a telephone. If the earthing 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 places, 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 on the condition, an odor may be generated or dehumidified water may not drain out smoothly due to dirt,
dust, etc. This may cause water leakage from the unit.
•
It is recommended that the unit be inspected and maintained (charged) by specialist in addition to normal maintenance.
Consult your dealer.
Operating sound considerations
•
Do not put an object around the air outlet of the outdoor unit. This may lower the capacity or increase the volume of the
operating sound.
•
If an abnormal sound is heard during operation, consult your dealer.
•
Choose the place which endures the unit weight enought and does not amplify the unit vibration.
•
Choose the place in which the operation sound and air blow from the unit don
’
t bother the house next door.
Relocation
•
When the air conditioner is to be removed or re-installed because of rebuilding, moving, etc., special techniques and
work are required.
WARNING :
Repairs or relocation should not be done by the customer.
If this is done incorrectly, it may cause a fire, an electric shock, or an injury from the unit falling, water leaking, etc.
Consult your dealer.

The installation location of the outdoor unit should be
at least 3 m away from the antennas for TV sets,
radios, etc. In areas where the reception is weak, pro-
vide greater space between the outdoor unit and the
antenna of the affected device if operation of the air
conditioner interferes with radio or TV reception.
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 places such as the seaside.
•
Where sulfide gas is generated such as a hot spring.
•
Where oil is splashed or where the area is filled with
oily smoke.
•
Where there is high-frequency or wireless equipment.
•
Where the unit will be buried in snow.
•
Inside the mobile vehicles such as a crane truck, ship, etc.
•
Drain the water from the unit to the soil which has good drainage.
•
Cooling and heating capacity may get lowered 10% in the places where poor ventilation and shortcycle of air exchange is likely to occur.
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 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 the power supply of the air conditioner.
•
Be sure to observe the breaker capacity.
WARNING :
• The customer should not install this unit.
If installation is done incorrectly, it may cause a fire, an electric shock, or injury from the unit falling, water leaking, etc.
• Do not use intermediate connection of the power supply cord or the extension cord and do not connect many
devices to one AC outlet.
A fire or an electric shock may result from poor contact, poor insulation, exceeding the permissible current, etc.
Consult your dealer.
