11.4.4 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.
Union
Vacuum drying
After completing the piping connection, execute vacuum drying for the connecting piping and the indoor unit.
The vacuum drying must be carried out by using the service ports of both the liquid and gas side valves.
CAUTION
Use two wrenches and tighten with regular torque.
