Changes in the product and components

In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged acciden- tally, service port diameter 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 size of opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)

Changes

 

 

As pressure is high, it is impossible to measure by means of conventional

Gauge manifold

 

gauge. In order to prevent any other refrigerant from being charged, each

 

 

 

port diameter is changed.

 

 

 

 

 

 

In order to increase pressure resisting strength, hose materials and port

size are changed (to 1/2 UNF 20 threads per inch).

 

 

 

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

 

 

 

 

Electronic balance

¡

 

As pressure is high and gasification speed is fast, it is difficult to read the

for refrigerant charging

 

indicated value by means of charging cylinder, as air bubbles occur.

 

 

 

 

 

 

Torque wrench

 

The sizes of opposite sides of flare nuts have been increased. Inciden-

(nominal diam. 1/2, 5/8)

 

 

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

 

 

 

 

Flare tool

¡

 

By increasing the clamp bar’s receiving hole, strength of spring in the tool

(clutch type)

 

has been improved.

 

 

 

 

 

 

Gauge for projection adjustment

Used when flare is made with using conventional flare tool.

 

 

 

 

 

 

 

Connected to the conventional vacuum pump. It is necessary to use an

 

 

 

adapter to prevent vacuum pump oil from flowing back to the charge hose.

The charge hose connecting part has two ports - one for conventional

 

refrigerant (7/16 UNF 20 threads per inch) and the other for R410A. If the

 

 

 

 

 

 

vacuum pump oil (mineral) mixes with R410A, sludge may occur and

 

 

 

damage the equipment.

Exclusive for HFC refrigerant.

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” require 1/2 UNF 20 threads per inch corresponding to the charge hose’s port size.
