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 circuit
is provided for this air conditioner and that all
electrical work is carried out by qualified per-
sonnel 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 do not bother your neighbors.
• 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.
