1. Form the piping according to its routing. Avoid
bending and bending back the same piping point
more than three times. (This will result in hard-
ening the pipe.)
2. After deforming the piping, align centers of the
union fitting of the indoor unit and the piping, and
tighten them firmly with wrenches.
3. Connect pipe to the service valve or ball valve
which is located below the outdoor unit.
4. After completing the piping connection, be sure
to check if there is gas leakage in indoor and
outdoor connection.
After completing the piping connection, execute
vacuum drying for the connecting piping and the
indoor unit.
The vacuum drying must be carried out using the
service ports of both the liquid and gas side valves.
Use two wrenches and tighten with regular torque.
