7. Installation and 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 much machine oil
•
near ocean and beach areas where there is much salt
•
where humidity is high
•
where there are hot springs nearby
•
where there is much sulfureted 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 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 electric engineer according to the [technical standard respecting elec-
trical installation], [internal wiring rules], and the installation instruction
manual with the absolute use of exclusive circuits. The use of other prod-
ucts with the power source can result in burnt-out beakers and fuses.

breaker is mandatory. For details, consult with your dealer.
Regarding transfer of installation
•
When removing and reinstalling the air conditioner when you enlarge your
home, remodel, or move, consult with your dealer in advance to ascertain the
cost of the professional engineering work required for transferring the installa-
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 do not inconvenience the neighbours.
•
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
drainage can deteriorate due to dust and dirt, etc.
