  • The charge hose must be connected in such a way that it is not slack.

Electrical wiring

  • Only a qualified installer(1) or qualified service person(1) is allowed to carry out the electrical work of the air conditioner. Under no circumstances must this work be done by an unqualified individual since failure to carry out the work properly may result in electric shocks and/or electrical leaks.
  • The appliance shall be installed in accordance with national wiring regulations. Capacity shortages of the power circuit or an incomplete installation may cause an electric shock or fire.
  • Use wiring that meets the specifications in the Installation Manual and the stipulations in the local regulations and laws. Use of wiring which does not meet the specifications may give rise to electric shocks, electrical leakage, smoking and/or a fire.
  • Be sure to connect earth wire. (Grounding work) Incomplete grounding causes an electric shock.
  • Do not connect ground wires to gas pipes, water pipes, and lightning rods or ground wires for telephone wires.
  • After completing the repair or relocation work, check that the ground wires are connected properly.
  • Install a circuit breaker that meets the specifications in the Installation Manual and the stipulations in the local regulations and laws.
  • 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 parts 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 receivean 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 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, etc.
  • After the work has finished, be sure to 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.
  • 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.

WARNING

  • After installation work, make sure below before operation.
    • Connection pipes are connected properly and no leakage.
    • Packed valves are fully open.

Running compressor without open packed valves may cause abnormal high pressure and parts failure.
Leakage at connection piping may suck air and make further high pressure cause burst and injure.

    Take off the knockout part of the pipe cover through which pipes or wires will pass through the base plate.

  • Detach the pipe cover and tap on the knockout section a few times with the shank of a screwdriver. A knockout hole can easily be punched.

  • After punching out the knockout hole, remove burrs from the hole and then install the supplied protective bush and guard material around the passage hole to protect wires and pipes. Be sure to attach the pipe covers after pipes have been connected. Cut the slits under the pipe covers to facilitate the installation.
    After connecting the pipes, be sure to mount the pipe cover. The pipe cover is easily mounted by cutting off the slit at the lower part of the pipe cover.

  • Be sure to wear heavy work gloves while working.
