4. INSTALLATION SITE
Regarding wiring
• All wiring must be performed by an authorized
electrician.
To do wiring, ask your dealer. Never do it by yourself.
• Make sure that a separate power supply cir-
cuit is provided for this air conditioner and
that all electrical work is carried out by quali-
fied personnel according to local laws and
regulations.
Pay attention to running noises, too
• Are the following places selected?
a. A place that can sufficiently withstand the
weight of the air conditioner with less running
noises and vibrations.
b. A place where the hot wind discharged from the
air outlet of the outdoor unit and the running
noises.
• Are you sure that there are no obstacles near
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running noises.
• If abnormal noises occur in use, consult your
dealer.
Regarding drainage of drain piping
• Is the drain piping executed to perform com-
plete drainage?
If proper drainage is not carried out from the out-
door drain pipes during air-conditioning operation,
chances are that dust and dirt are clogged in the
pipe. This may result in a water leakage from the
indoor unit. Under such circumstances, stop the
operation of the air conditioner, and then consult
your dealer or our service station.
