Installation of new refrigerant air

conditioner

CAUTION

New refrigerant air conditioner installation

 This air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer.

R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working

pressure of R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the new

refrigerant, the refrigerant oil has also been changed. Therefore, during installation w

ork, be sure that water, dust,

former refrigerant, or refrigerant oil does not enter the new type refrigerant R410A air conditioner circuit.

To prevent mixing of refrigerant or refrigerant oil, the sizes of connecting sections of charging port on main unit and

installation tools are different from those of the conventional refrigerant units. Accordingly, special tools are required for

the new refrigerant (R410A) units. For connecting pipes, use new and clean piping materials with high pressure fittings

ade for R410A only, so that water and/or dust does not enter.

Required tools / equipment and precautions for use

Prepare the tools and equipment listed in the following table before starting the installation work.

Newly prepared tools and equipment must be used exclusively.
