(3) Carefully bend the tubing (if necessary) to run along the
wall in the direction of the outdoor unit and then tape as far
as the fittings. The drain hose should come straight down
the wall to a point where water runoff won't stain the wall.
(4) Connect the refrigerant tubing to the outdoor unit. (After
performing a leak test on the connecting part, insulate it
with the tubing insulation. (Fig. 3-62)
