• Under no circumstances, the power supply wire or the indoor and
outdoor connecting wire must not be connected in the middle
(Connection using a solderless terminal etc.)
Connection trouble in the places where the wire is connected in the
middle 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.
• Check that wiring will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse environmental
effects. The check shall also take into account the effects of aging or
continual vibration from sources such as compressors or fans.
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 check code 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 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 trouble.
• After the work has finished, use an insulation tester set (500 V
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.
11-EN
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.
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.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person".
