After the leak test, apply insulating material tightly so that there
is no gap.
When the piping is to be attached to a wall containing metals (tin
plated) or metal netting, use a chemically treated wooden piece
3/4 in. (20 mm) or thicker between the wall and the piping or wrap
7 to 8 turns of insulation vinyl tape around the piping.
To use existing piping, perform COOL operation for 30 minutes and
pump down before removing the old air conditioner. Remake flare
according to the dimension for new refrigerant.
