The following symptoms are not air conditioner failures:
•
The air blown out from the air conditioner can sometimes give off odors. This is
due to cigarette smoke contained in the air of the room, the smell of cosmetics,
the walls, furniture, etc., absorbed in the air conditioner.
•
A hissing noise can be heard immediately after the air conditioner is started or
stopped. This is the sound of the refrigeration flowing inside the air conditioner.
This is normal.
• The air conditioner sometimes snaps or clicks at the beginning or end of
cooling/heating operation. This is the sound of friction on the front panel and
other sections due to expansion and contraction caused by temperature
change. This is normal.
• The fan speed changes in spite of not changing the setting. Not to blow out cold
air at the beginning of heating operation, the air conditioner automatically
adjusts the fan speed gradually from lower to the set speed. It also adjust its fan
speed to protect the fan motor when return air temperature or fan speed
excessively rises.
7. 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 installation 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
instruction 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.
• Never connect the grounding wire to a gas pipe, water pipe, arrester, or
telephone grounding wire. For details, consult with your dealer.
• In some types of installation sites, the installation of an earth leakage
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
installation.
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
conditioner, 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 drainage can deteriorate due to dust and
dirt, etc.
