Concealed Duct High Static Pressure

Installation Manual

CAUTION

New Refrigerant Air Conditioner Installation

•THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE LAYER.

•The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22.

Accompanied with the new refrigerant, refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle.

•To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the main unit and installation tools are changed from those for the conventional refrigerant.

•Accordingly the exclusive tools are required for the new refrigerant (R410A).

•For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not enter.

To Disconnect the Appliance from Main Power Supply.

•This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.

•The installation fuse must be used for the power supply line of this conditioner.
