11.9.4 REFRIGERANT
PIPING
Refrigerant is charged to the outdoor unit. For details, see the manual for installation work of outdoor unit. (Additional
charging, etc.)
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.
•
Confirm the black mark of the union (thin side) is
always at lower direction after connecting piping.
