has to be done at the main power
distribution.This distribution has to be of a
Iow impedance. Normally the required
impedance is reached at a 32A fusing point.
2.No other equipment has to be connected:
to this power line.
3.For the details installation acceptance
please refer to your contract with the power
supplier, if restrictions do apply for products:

Operation
When in use, put the signal transmission head directly to the
receiver hole on the indoor unit.
The distance between the signal transmission head and the
receiver hole should be within 7 m without any obstacle as well.
Don't throw the controller, prevent it from being damaged.
When electronic-started type fluorescent lamp or change-over
type fluorescent lamp or wireless telephone is installed in the
room, the receiver is apt to be disturbed in receivering the signals
so the distance to the indoor unit should be shorter.

When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
During unit operation or at stop, a swishing
or gurgling noise may be heard. At first 2-3
minutes after unit start, this noise is more
noticeable. (This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking noise may
be heard. This noise is generated by the
casing expanding or shrinking because of
temperature changes
Should there be a big noise from air flow in
unit operation, air filter may be too dirty.
This is because the system circulates smells
from the interior air such as the smell of
furniture, cigarettes.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.

Is there a power failure?
Is fuse blown out?
