7 FINAL INSTALLATION CHECKS

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 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)

New tools for R410A

New tools for R410A	Applicable to R22 model		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
Charge hose	⋅		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.
for refrigerant charging

Torque wrench	⋅		The size of opposite sides of flare nuts have been increased. Incidentally,
(nominal diam. 1/2, 5/8)			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.
(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.
Vacuum pump adapter	¡		The charge hose connecting part has two ports-one for conventional
Vacuum pump adapter	¡		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.
