In the case of an air conditioner using R410A, in order to prevent
any other refrigerant from being charged accidentally, service port

• 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.

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)
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 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.
As 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 opposite sides of 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, strength of spring in the tool
has been improved.
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 one for R410A.
If the vacuum pump oil (mineral) mixes with R410A a sludge may occur
and damage the equipment.
Exclusive for HFC refrigerant.
