After the installation work, confi rm that refrigerant gas does not
•
leak. If refrigerant gas leaks into the room and fl ows near a fi re
source, such as a cooking range, noxious gas may be generated.
•
When the air conditioner has been installed or relocated,
follow the instructions in the Installation Manual and purge
the air completely so that no gases other than the refrigerant
will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.
•
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not
•
slack.
Electrical wiring
•
Only a qualifi ed installer or qualifi ed service person is allowed
to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unqualifi ed
individual since failure to carry out the work properly may result
in electric shocks and/or electrical leaks.
To connect the electrical wires, repair the electrical parts or
•
undertake other electrical jobs, wear gloves to provide protection
for electricians, insulating shoes and clothing to provide
protection from electric shocks.
Failure to wear this protective gear may result in electric shocks.
Use wiring that meets the specifi cations in the Installation Manual
•
and the stipulations in the local regulations and laws. Use of
wiring which does not meet the specifi cations may give rise to
electric shocks, electrical leakage, smoking and/or a fi re.
Connect earth wire. (Grounding work)
•
Incomplete grounding causes an electric shock.
Do not connect grounding wires to gas pipes, water pipes, and
•
lightning conductor or telephone grounding wires.
•
After completing the repair or relocation work, check that the
grounding wires are connected properly.

Install a circuit breaker that meets the specifi cations 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.
•
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 fi re.
•
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 fi rst 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 but set the circuit
breaker to the OFF position, and contact a qualifi ed 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 qualifi ed 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.
After the work has fi nished, use an insulation tester set
•
(500V Megger) to check the resistance is 1MΩ or more
between the charge section and the non-charge metal section
(Earth / Ground section). If the resistance value is low, a disaster
such as a leak or electric shock is caused at user's side.
