• 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, stop the oper-
ation of the air conditioner, and then consult
your dealer or our service station.
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.
