6. Installation, transferring works, and checking

Regarding place for installation
Consult with your dealer for details on installation and transferring the installation.
Caution:
Never install the air conditioner where there is a risk of leakage of flammable
gas.
If gas leaks and accumulates around the unit, fire can result.
Never install the air conditioner at the following place:
• where there is a lot of machine oil
• near the ocean and beach areas where there is salt air.
• where humidity is high
• where there are hot springs nearby
• where there is sulphurous gas
• where there is a high-frequency processing machinery (a high-frequency welder,
etc.)
• where acid solution is frequently used
• where special sprays are frequently used
• Install the indoor unit horizontally. Otherwise, water leakage can result.
• Take sufficient measures against noise when installing the air conditioners at
hospitals or communication-related businesses.
If the air conditioner is used in any of the above-mentioned environments, frequent
operational failure can be expected. It is advisable to avoid these types of installa-
tion sites.
For further details, consult with your dealer.
Regarding electrical work
Caution:
• The electrical work must be undertaken by a person who is qualified as
an electrical engineer according to the [technical standard respecting
electrical installation], [internal wiring rules], and the installation instruc-
tion manual with the absolute use of exclusive circuits. The use of other
products with the power source can result in burnt-out beakers and fuses.

tion.
Caution:
When moving or reinstalling the air conditioner, consult with your dealer.
Defective installation can result in electric shock, fire, etc.
Regarding noise
• In installing work, choose a place that can fully bear the weight of the air con-
ditioner, and where noise and vibration can be reduced.
• Choose a place where cool or warm air and noise from the outdoor air outlet of
the air conditioner does not inconvenience the neighbors.
• If any alien object is placed near the outdoor air outlet of the air conditioner,
decreased performance and increased noise can result. Avoid placing any
obstacles adjacent to the air outlet.
• If the air conditioner produces any abnormal sound, consult with your dealer.
Maintenance and inspection
• If the air conditioner is used throughout several seasons, the insides can get
dirty, reducing the performance.
Depending upon the conditions of usage, foul odors can be generated and
