Concealed Duct High Static Pressure

Installation Manual

 

Refrigerant piping

•Install the refrigerant pipe securely during the installation work before operating the air conditioner. If the compressor is operated with the valve open and without refrigerant pipe, the compressor sucks air and the refrigeration cycles is over pressurized, which may cause a injury.

•Tighten the flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage.

•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.

•When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the air completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air completely may cause the air conditioner to malfunction.

•Nitrogen gas must be used for the airtight test.

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

•If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes in contact with fire, noxious gas may be generated.

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.

 

• When connecting the electrical wires, repairing the electrical parts or undertaking other electrical jobs, wear gloves to

 

provide protection for electricians and from heat, insulating shoes and clothing to provide protection from electric shocks.

 

Failure to wear this protective gear may result in electric shocks.

 

• 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

EN

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.

•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.

Test run

•Before operating the air conditioner after having completed the work, check that the electrical parts 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.

•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 (500V Megger) to check the resistance is 2 M! 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.

•If you have discovered that the fan grille 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 rupture, injury or other trouble.

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