• 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 fire.
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 etc. if
the power is turned on without first conducting these checks.
• When you have noticed that some kind of trouble (such as when a
check 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, etc.
• After the work has finished, be sure to use an insulation tester set
(500 VMΩ) 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.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source,
such as a cooking range, noxious gas may be generated.
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 guard 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, etc. to be sucked in, raising the pressure
inside the refrigeration cycle to an abnormally high level, and possibly
resulting in reputing, injury, etc.
(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person.”
