Once you have checked that there are no leaks in the system, you can insulate the piping,
hose and cables and place the indoor unit on the installation plate.
1To avoid condensation problems, place heat-resistant polyethylene foam separately
around each refrigerant pipe in the lower part of the indoor unit.
2Wrap the refrigerant pipes and the drain hose located at the rear of the indoor unit up
in the absorbent pad.
➢Triply wind the pipes and hose to the end of the indoor unit with the absorbent pad
[make intervals of inch(20mm)].
3Wind insulating tape around the pipes, assembly cable and drain hose.
4Place the resulting bundle carefully in the lower part of the indoor unit, making sure that
it does not jut out from the rear of the indoor unit.
5Hook the indoor unit on to the installation plate and move the unit to the right and left
until you are sure that it is securely in place.
6Finish wrapping vinyl tape around the rest of the piping leading to the outdoor unit.
7Using clamps (optionally supplied), attach the piping to the wall wherever possible.
