• For refrigerant leakage, consult your dealer.
Refrigerant leakage in excess of the level of con-
centration limits may result in oxygen deficiency.
When the air conditioner is installed in a small
room, it is necessary to take proper measures so
that the amount of any leaked refrigerant will not
exceed the limiting concentration even if it leaks.
CAUTION for installation
• Do not install the air conditioner in places
where flammable gas may leak out.
Leaked gas may accumulate around the unit,
causing an explosion.
• Do not locate the remote controller in a spot
splashed with water.
Water coming inside the machine may cause elec-
tric shocks or may damage the internal electronic
parts.
• Arrange the drain hose to ensure smooth
drainage.
Incomplete drainage may cause water leakage.
[Place of Installation]
• Make sure that the air conditioner is located in
a sufficiently ventilated place not surrounded
by obstacles.
• Do not use the air conditioner in the following
places.
a.
Places with a mist of mineral oil, such as cutting
oil.
b. Locations such as coastal areas where there is
a lot of salt in the air.
c. Locations such as hot springs resorts where
there is a lot of sulfur in the air.
d. Locations such as factories where the power
voltage varies a lot.
e. In cars, boats, and other vehicles.
f. Locations such as kitchens where oil may splat-
ter or there is steam in the air.
g. Locations where equipment that produces elec-
tromagnetic waves is found.
h. Places with an acid or alkaline mist.
i. Places where fallen leaves are accumulated or
weeds grow close together.
• Take snow protection measures.
Contact your dealer for the details of snow protec-
tion measures, such as the use of a snow protec-
tion hood.
[Electrical Work]
• Do not attempt to conduct electrical work or
grounding work unless you are licensed to do so.
Consult with your dealer for electrical work and
grounding work.
• Use a dedicated circuit for the air conditioner.
[Pay Attention to Operating Sound]
• Be sure to use the following places.
a. Places that can sufficiently withstand the weight
of the air conditioner and suppress the operat-
ing sound and vibration of the air conditioner.
b. Places where warm air from the air outlet of the
outdoor unit or the operating sound of the out-
door unit does not annoy neighbors.
• Make sure that there are no obstacles close to
the outdoor unit.
Obstacles close to the outdoor unit may drop the
performance of the outdoor unit or an increase in
the operating sound of the outdoor unit.
• Consult your dealer if the air conditioner in
operation generates unusual noise.
[Drainage through Drainpipe]
• Make sure that the drainpipe is installed prop-
erly to drain water.
If no water is discharged from the drainpipe while
the air conditioner is cooling operation, the drain-
pipe may be clogged with dust or dirt and water
leakage from the indoor units may result.
Stop operating the air conditioner and consult your
dealer.
