• Is a snow protection measure taken?
For details, consult your dealer.
Regarding wiring
• All wiring must be performed by an authorized electri-
cian.
To do wiring, ask your dealer. Never do it by yourself.
• Make sure that a separate power supply circuit is pro-
vided for this air conditioner and that all electrical
work is carried out by qualified 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 performance and
increased running noises.
• If abnormal noises occur in use, consult your dealer.
Regarding drainage of drain pipe
• Is the drain pipe executed to perform complete drain-
age?
If proper drainage is not carried out from the outdoor 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 circum-
stances, stop the operation of the air conditioner, and then
consult your dealer or our service station.
