9-1-4. Installation/Servicing Tools <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 accidentally, the 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

 

 

 

 

Gauge manifold

 

 

As pressure is high, it is impossible to measure by

 

 

 

means of conventional gauge. In order to prevent any

 

 

 

other refrigerant from being charged, each port

 

 

 

diameter has been changed.

 

 

 

 

Charge hose

 

 

In order to increase pressure resisting strength, hose

 

 

 

materials and port size have been changed (to 1/2

 

 

 

UNF 20 threads per inch).

 

 

 

When purchasing a charge hose, be sure to confirm

 

 

 

the port size.

 

 

 

 

Electronic balance

 

 

As pressure is hight and gasification speed is fast, it

for refrigerant charging

 

 

is difficult to read the indicated value by means of

 

 

 

charging cylinder, as air bubbles occur.

 

 

 

 

Torque wrench

 

 

The size of opposite sides of flare nuts have been

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

 

 

increased. Incidentally, a common wrench is used for

 

 

 

nominal diameters 1/4 and 3/8.

 

 

 

 

Flare tool

 

 

By increasing the clamp bar’s receiving hole, strength

(clutch type)

 

 

of spring in the tool has been improved.

 

 

 

 

Gauge for projection

—

 

Used when flare is made by using conventional flare

adjustment

 

tool.

 

 

 

 

 

 

Vacuum pump adapter

 

 

Connected to 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 one for R410A. If the vacuum pump oil

 

 

 

(mineral) mixes with R410A a sludge may occur and

 

 

 

damage the equipment.

 

 

 

 

Gas leakage detector

 

 

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.
