Do not connect earth wires to gas pipes, water pipes, and
lightning conductor or telephone earth wires.
After completing the repair or relocation work, check that the
earth wires are connected properly.
Install a circuit breaker that meets the specifications in the
Installation Manual and the stipulations in the local regulations
and laws.
Install the circuit breaker where it can be easily accessed by the
agent.
When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
Under no circumstances the power wire must not be extended.
Connection trouble in the places where the wire is extended may
give rise to smoking and/or a fire.
Electrical wiring work shall be conducted according to law and
regulation in the community and Installation Manual.
Failure to do so may result in electrocution or short circuit.
Test run
Before operating the air conditioner after having completed the
work, check that the electrical control box cover of the indoor
unit and service panel of the outdoor unit are closed, and set the
circuit breaker to the ON position. You may receive an electric
shock if the power is turned on without first conducting these
checks.
If there is any kind of trouble (such as an error display has
appeared, smell of burning, abnormal sounds, the air conditioner
fails to cool or heat or water is leaking) has occurred in the air
conditioner, do not touch the air conditioner yourself but set
the circuit breaker to the OFF position, and contact a qualified
service person. Take steps to ensure that the power will not be
turned on (by marking "out of service" near the circuit breaker, for
instance) until qualified service person arrives. Continuing to use
the air conditioner in the trouble status may cause mechanical
problems to escalate or result in electric shocks or other trouble.
11-EN
After the work has finished, use an insulation tester set
(500V Megger) to check the resistance is 1M
the charge section and the non-charge metal section (Earth section).
If the resistance value is low, a disaster such as a leak or electric
shock is caused at user's side.
Upon completion of the installation work, check for refrigerant
leaks and check the insulation resistance and water drainage.
Then conduct a test run to check that the air conditioner is
operating properly.
Explanations given to user
Upon completion of the installation work, tell the user where the
circuit breaker is located. If the user does not know where the
circuit breaker is, he or she will not be able to turn it off in the
event that trouble has occurred in the air conditioner.
After the installation work, follow the Owner's Manual to explain
to the customer how to use and maintain the unit.
Relocation
Only a qualified installer(*1) or qualified service person(*1) is
allowed to relocate the air conditioner. It is dangerous for the air
conditioner to be relocated by an unqualified individual since a
fire, electric shocks, injury, water leakage, noise and/or vibration
may result.
When carrying out the pump-down work shut down the
compressor before disconnecting the refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left open
and the compressor still operating will cause air or other gas to
be sucked in, raising the pressure inside the refrigeration cycle to
an abnormally high level, and possibly resulting in rupture, injury
or other trouble.
