• After the work has
fi
nished, use an insulation tester set (500V Megger) to
check the resistance is 1M
Ω
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 quali
fi
ed 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.
Relocation
• Only a quali
fi
ed installer or quali
fi
ed service person is allowed to relocate
the air conditioner. It is dangerous for the air conditioner to be relocated by
an unquali
fi
ed individual since a
fi
re, electric shocks, injury, water leakage,
noise and/or vibration may result.
• While 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.
