• 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.
• Make sure that the circuit breaker is attached. If it is not, the electric shock may be caused.
• Do not use the fuse other than the correct capacity. Use of wire or copper wire may result in
fire or malfunction.
• Ensure that the power is the rated voltage and use the circuit special for the Dx-coil interface.
Test run
• Before operating the air conditioner after having completed the work, check that the electrical
control box cover of the air handling 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 a check 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 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.
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 or qualified service person 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.
Repair • Maintenance
• Request the repair to the distributor that you made your purchase from.
• If there is a defect in the repair, the fire, electric shock may be caused.
• Turn off the circuit breaker of the entire system including the AHU and the outdoor unit when
performing the repair or the maintenance.
• Frequent washing by water is advised/suggested in case is installed seaside area.
(Prevent any water access to electrical parts during washing)
• Any scratch and/or crack happened during installation/maintenance must be repaired.
• Frequent maintenances and inspections are advised and further anti-rust treatment or parts.
