unit, insulating the cables, hose and pipe, a
door unit to the
installation plate)

Fixing the indoor Unit in Place
After checking for gas leaks in the system, insulate the pipe, hose and cables.
Then place the indoor unit on the installation plate.
1 To avoid condensation problems, place heat-resistant polyethylene foam
separately around each refrigerant pipe in the lower part of the indoor unit.
2 Wrap the refrigerant pipe and the drain hose in the rear of the indoor unit with
the absorbent pad.
3 Wind the pipe, assembly cable and drain hose with insulation tape.
4 Place the bundle (the pipe, assembly cable and drain hose) in the lower part of
the indoor unit carefully so it doesn’t project from the rear of the indoor unit.
5 Hook the indoor unit to the installation plate and move the unit to the right
and left until it is securely in place.
6 Wrap the rest of the pipe with vinyl tape.
7 Attach the pipe to the wall using clamps (optional).

▶
Before inspecting the leakage, use a torque wrench to close
the cap for the service valve. (Comply with a tightening torque
to prevent any leakage.)
▶
To check for any possible leakage, insert inert gas into the pipes
connected to indoor/outdoor units and check the connection part
of the indoor/outdoor units with soap lather or liquid for leakage test.
