To check for gas leaks on the indoor unit, check the connection part
of each refrigerant pipe by using a leak detector.
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
To avoid condensation problems, place T13.0 or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
1
Wind insulating tape around the pipes.
2
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

Always make the seam of pipes face upwards.
