• Be sure to connect earth wire. (Grounding work)
Incomplete grounding causes an electric shock.
• Do not connect ground wires to gas pipes, water pipes, and lightning rods or
ground wires for telephone wires.
• After completing the repair or relocation work, check that the ground 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.
• When installing the circuit breaker outdoors, install one which is designed to
be used outdoors.
• Under no circumstances must the power cable be extended. Connection
trouble in the places where the cable 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/short circuit.
Test run
• Before operating the air conditioner after having completed the work, check
that the front panel 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.
• When you have noticed that some kind of trouble (such as when an error
display has appeared, there is a smell of burning, abnormal sounds are
heard, 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 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, etc.
• After the work has fi nished, be sure to use an insulation tester set (500V
Megger) to check the resistance is 1 MΩ or more between 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.
