CAUTION

TAKE NOTICE THESE IMPORTANT 4 POINTS BELOW FOR PIPING WORK

1.Keep dust and moisture away from inside the connecting pipes.

2.Tightly connect the connection between pipes and the unit.

3.Evacuate the air in the connecting pipes using VACUUM PUMP.

4.Check gas leak at connected points.

4 REFRIGERANT PIPING

Flaring

1. Cut the pipe with a pipe cutter.

OK	NO GOOD
90˚	Obliquity Roughness Warp

2.Insert a flare nut into the pipe, and flare the pipe.

As the flaring sizes of R410A differ from those of refrigerant R22, the flare tools newly manufactured for R410A are recommended.

However, the conventional tools can be used by adjusting projection margin of the copper pipe.

• Flaring size : A (Unit : mm) A

	A	+0
Outer diam. of copper pipe		- 0.4
	R410A		R22
6.4	9.1		9.0
9.5	13.2		13.0
12.7	16.6		16.2
15.9	19.7		19.4

*In case of flaring for R410A with the conventional flare tool, pull it out approx. 0.5 mm more than that of R22 to adjust to the specified flare size.

The copper pipe gauge is useful for adjusting projection margin size.

•Projection margin in flaring : B (Unit : mm)
