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.
•
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 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 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.

●
“HO” is displayed in the remote controller.
• An automatic startup test is being performed (will last for about two minutes).
●
An error code is displayed in the remote controller.
• A self-diagnostic function is being performed to preserve the air conditioner.
* Do not attempt to make repairs yourself. Turn the main switch off and
contact the dealer from whom you bought the air conditioner. Provide him
or her with the name of the unit and the information displayed in the re-
mote controller.
●
The fan in the unit does not operate.
• Check the over-current relay on the fan motor to determine whether it has
been tripped.
If the over-current relay has been tripped, reset it after eliminating the cause
of the problem (e.g. motor lock).
To reset the over-current relay, open the control box and press the green
claw on bottom-right of the relay until a click is heard. Release the claw and
check that it returns to its original position.
Note that if it is pressed too hard it will not return to its original position.
NOTE:
The following do not indicate any malfunction:
Odours: smells such as tobacco or cosmetic odours may persist after they have
been sucked into the unit.
Sound of liquid flowing inside air inlet and outlet part: this can occur during or after
operation and is simply the sound of refrigerant being circulated inside the unit.
Ticking sound coming from air inlet and outlet part: this can occur when cooling or
heating has just begun or has just stopped. It is caused by the indoor unit shrinking
or expanding slightly due to the change in temperature.
The message “CENTRALLY CONTROLLED” appearing on the LCD panel: from
time to time, this message may come up on the LCD panel. This does not indicate
any malfunction.
