5. Installation, reinstalling, and maintenance
Installation area
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 places:
• where there is a lot of machine oil
• direct exposure to the ocean and beach.
• where humidity is high
• where there are hot springs nearby
• where there is sulphuric 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 electrical noise when installing the air condi-
tioners 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 the dealer.
Regarding electrical work
Caution:
• The electrical work must be performed by a qualified contractor accord-
ing to the technical standard respecting electrical installation, internal
wiring rules, and the installation instruction manual with the absolute
use of exclusive circuits. The use of other products with the power source
can result in burnt-out breakers and fuses.
•Never connect the grounding wire to a gas pipe, water pipe, arrester, or
telephone grounding wire. For details, consult with the dealer.
• In some types of installation sites, the installation of an grand breaker is
mandatory. For details, consult with the dealer.
Regarding transfer of installation
• If removing and reinstalling the air conditioner, consult with the dealer in ad-
vance to ascertain the cost of the professional engineering work.
Caution:
When moving or reinstalling the air conditioner, consult with the dealer. De-
fective installation can result in electric shock, fire, etc.
Regarding sound
• 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 sound from the outdoor air outlet
of the air conditioner does not inconvenience the neighbors.
• If any obstacles are placed near the outdoor air outlet of the air conditioner,
decreased performance and increased noise can result. Avoid placing any ob-
stacles adjacent to the air outlet.
• If the air conditioner produces any abnormal sound, consult with the dealer.
Maintenance and inspection
• If the air conditioner is used throughout several seasons, the internal compo-
nents 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.
