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 (*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.
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.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person."
