• The dimensions of ceiling opening can be regulated within the range shown
in following diagram; so center the main unit against the opening of ceiling,
ensuring that the respective opposite sides on all sides of the clearance
between them becomes identical.
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
13/16 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
