• 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.
• 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 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.
• After the work has finished, 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.
• 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.
• If the fan grille is damaged, do not approach the outdoor unit but set the
circuit breaker to the OFF position, and contact a qualified service person
to have the repairs done. Do not set the circuit breaker to the ON position
until the repairs are completed.
• After the installation work, follow the Owner's Manual to explain to the
customer how to use and maintain the unit.
