All field wiring and components must be installed by a
licensed electrician and must comply with relevant
local and national regulations.

The field wiring must be carried out in accordance
with the wiring diagrams and the instructions given
below.

Be sure to use a dedicated power circuit. Never use a
power supply shared by another appliance. This can
lead to electrical shock or fire.

Insufficient capacity of the power supply circuit or
improper electrical construction may lead to electric
shocks or fire.

Do not operate until refrigerant piping work is
completed.
(If operated before completion of the piping work, the
compressor may break down.)

Never remove a thermistor, sensor, etc., when
connecting power wiring and transmission wiring.
(If operated without thermistor, sensor, etc., the
compressor may break down.)

The reversed phase protection detector of this product
only works during the initialisation stage after a power
reset.
The reversed phase protection detector is designed to
stop the product in case of an abnormality when the
product is started up.
When the reversed phase protection circuit forced the
unit to stop, check if all phases are existing. If this is
the case, shut off the power supply to the unit and
replace two of three phases. Turn on power again and
start the unit.

Reversed phase detection is not performed while the
product is operating.

In case of possible reversal of phases after a
momentary black out of power and the power goes on
and off while the product is operating, install a
reversed phase protection circuit on site. Such
situation is not unimaginable when using generators.
Running the product in reversed phase can break the
compressor and other parts.

Ground the air conditioner.
Grounding resistance should be according to national
regulations
Do not connect the earth wire to gas or
water pipes, lightning conductor or
telephone earth wire.
Incomplete grounding may cause electric
shocks.

Gas pipe.
Ignition or explosion may occur if the gas leaks.

Water pipe.
Hard vinyl tubes are not effective grounds.

Lightning conductor or telephone ground wire.
Electric potential may rise abnormally if struck by a
lightning bolt.

Be sure to install an earth leakage breaker and fuse.
Failure to install an earth leakage breaker may cause
electric shocks and fire.
