Performing Leak Test & Insulation
NBR(T13.0 or thicker)
Be sure to overlap
Must fit tightly against
body without any gap.
To check for gas leaks on the indoor unit, check the connection part

Butadien Rubber separately around each refrigerant pipe.
Always make the seam of pipes face upwards.
Wind insulating tape around the pipes.
Finish wrapping insulating tape around the rest of the pipes leading to the
