Refrigerant Piping Work

Flaring the pipe end

1) Cut the pipe end with a pipe cutter.

2) Remove burrs with the cut surface facing down-

ward so that the chips do not enter the pipe.

3) Put the flare nut on the pipe.

4) Flare the pipe.

5) Check that the flaring is properly made.

WARNING

1) Do not use mineral oil on flared part.

2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.

3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.

4) Do never install a drier to this R410A unit in order to guarantee its lifetime.

5) The drying material may dissolve and damage the system.

6) Incomplete flaring may cause refrigerant gas leakage.
