1. Brazing for piping.
a. Execute brazing before tightening the flare nut.
b. Brazing must be executed while blowing nitrogen gas. (This
prevents generation of oxidized scale in copper pipe.)
2. When there is a lot of brazings for long piping, install a strainer
midway of the piping. (The strainer is locally supplied.)
3. Use clean copper pipe with inner wall surface free from mist and
dust. Blow nitrogen gas or air to blow off dust in the pipe before
connection.
4. Form the piping according to its routing. Avoid bending and bending
back the same piping point more than three times. (This will result
in hardening of the pipe).
5. After deforming the pipe, align centers of the union fitting of
the indoor unit and the piping, and tighten them firmly with
wrenches.
6. Connect pipe to the service valve or ball valve which is located
below the outdoor unit.
7. After completed the piping connection, be sure to check if there is
gas leakage in indoor and outdoor connection.
