Once you have checked that there are no leaks in the system, you can insu-
late the piping and hose.
To avoid condensation problems, place an insulator around each
refrigerant pipe.
1
When insulate the pipe, be sure to overlap the insulation.
You have to use more than 120°C insulation(T13.0 or thicker
Acrylonitrile Butadien Rubber) for the gas refrigerant pipe.
Note
No gap

When using the air conditioner in the heating mode, ice may accumu-
late. During de-icing, the condensed water must be drained off safely.
Consequently, you must install a drain hose on the outdoor unit, following the
instructions below.
Make space more than 50mm between the bottom of the outdoor unit
and the ground for installation of the drain hose, as shown in figure.
1
Insert the drain plug into the hole on the underside of the outdoor unit.
2
Connect the drain hose to the drain plug.
