1.Remove the front panel of the unit.

2.Remove the pipe cover.

3.Remove the appropriate knockout depending on the orientation of the piping.

The pipe cover is easily mounted by cutting off the slit at the lower part of the pipe cover.

Flaring

1.Cut the pipe with a pipe cutter.

Be sure to remove burrs that may cause a gas leak.

2.Insert the supplied flare nut into the pipe, and then 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
