Leak Test
Insulation
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
1
To avoid condensation problems, place T13.0 or thicker Acrylonitrile
Butadiene Rubber around each refrigerant pipe.
Note
Always make the seam of pipes face upwards.
2
Wind insulating tape around the pipes and drain hose.
3
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.
