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.

•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.

Align the centres of the connecting pipes and tighten the flare nut as strong as possible with your fingers.

Then fix the nut with a spanner and tighten it with torque wrench as shown in the figure.

•As shown in the figure, use two spanners to unscrew or tighten the valve flare nut, at gas side.

If using a single spanner, the nut cannot be tightened with necessary tightening torque.

On the contrary, use a single spanner to loosen or tighten the flare nut of the valve at liquid side.

REQUIREMENT:

1.Do not put the spanner on the cap. The valve may be broken.

2.If applying excessive torque, the nut may be broken according to some installation conditions.

•After the installation work, be sure to check gas leak of connecting part of the pipes with nitrogen.

•Pressure of R410A is higher than that of R22 (Approx. 1.6 times).

Therefore, using a torque wrench, tighten the flare pipe connecting sections which connect the indoor/outdoor units at the specified tightening torque.

Incomplete connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.

IMPORTANT:

Do not apply refrigerating machine oil to the flared surface.
