Piping preparation

Before proceeding with piping installation, the pipes need to be
prepared. For that you will need a pipe cutter and a proper flaring tool.
The following information describes how to prepare the piping for
installation.
▶ Use the pipe cutter for cutting the pipes
Fig. 12
▶ Remove all burrs by using a copper pipe reamer. Hold the pipe
downwards to allow any metal debris to fall out, preventing it from
remaining in the pipe.
Gas leaks might occur if the burrs are not correctly removed.

▶ Wrap the insulated pipe end to prevent water from going inside
piping.

the rounds are even. If this is not observed and the flare is defective
(uneven rounds, scratches, cracked or tilted), redo the flaring process.

Connect the outdoor unit pipes to the indoor unit

To connect the pipes from the outdoor unit to the indoor unit, a hole in
the wall might be necessary. For that consider a Ø 60 mm hole core drill .
After pipes are prepared as mentioned in chapter 5.2.3, you can
connect them to the outdoor unit.
