CAUTION

Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R410A) and protector coating in the

U.S's ARI specified rose color (ARI color code: PMS 507).

Also, the "charge port and packing for refrigerant cylinder" requires 1/2 UNF 20 threads per inch corresponding

to the charge hose's port size.

New Refrigerant Air Conditioner Installation

THIS AIR CONDTIONER 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 of refrigerant R22. Accompanied with the adoption of the new refrigerant, the

refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant,

or refrigeration machine oil does not enter into the new type refrigerant R410A air conditioner circuit.

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

installation tools are different from those used for 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 made for

R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are some

problems with pressure fittings and possible impurities in existing piping.

Changes in the product and components

In air conditioners using R410A, in order to prevent any other refrigerant from being accidentally charged, the service port

diameter size of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)

In order to increase the pressure resisting strength of the refrigerant piping, flare processing diameter and

opposing flare nuts sizes have been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)

As the working pressure is high, it is impossible to measure the

working pressure using conventional gauges. In order to prevent

any other refrigerant from being charged, the port diameters have

been changed.

In order to increase pressure resisting

strength, hose materials

and port

sizes have been changed (to 1/2 UNF 20 threads per

inch).

When purchasing a charge hose, be sure to confirm the port size.

As working pressure is high and gasification speed is fast, it is

difficult to read the indicated value by means of charging cylinder,

as air bubbles occur.

The size of opposing flare nuts have been increased. Incidentally,

a common wrench is used for nominal diameters 1/4 and 3/8.

By increasing the clamp bar's receiving hole size, strength of

spring in the tool has been improved.

Used when flare is made by using conventional flare tool.

Connected to conventional vacuum pump. It is necessary to use

an adapter to prevent vacuum pump oil from flowing back into

the charge hose. The charge hose connecting part has two ports

-- one for conventional refrigerant (7/16 UNF 20 threads per inch)

and one for R410A. If the vacuum pump oil (mineral) mixes with

R410A a sludge may occur and damage the equipment.

Exclusive for HFC refrigerant.
