System Configuration
•
Make sure that a separate power supply circuit is
provided 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 declinded performance and
increased running noises.
•
If abnormal noises occur in use, stop the operation of
the air conditioner, and then cunsult your dealer or our
service station.
Regarding drainage of drain piping
•
Is the drain piping executed to perform complete
drainage?
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
circumstances, stop the operation of the air conditioner,
and then consult your dealer or our service station.
