Test run
• Before operating the air conditioner after having completed the
work, check that the electrical parts 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.
• 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 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 failure.
• After the work has finished, 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.
• If you have discovered that 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(*1) 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 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.
• Never recover the refrigerant into the outdoor unit. Be sure to
use a refrigerant recovery machine to recover the refrigerant
when moving or repairing. It is impossible to recover the
refrigerant into the outdoor unit. Refrigerant recovery into the
outdoor unit may result in serious accidents such as explosion of
the unit, injury or other accidents.
(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person.”
