► Use a core drill to make a hole of 100 mm, 3-15/16 inch diameter in the wall
in the piping direction, at the position shown in the diagram to the left.
► The hole should incline so that the outside opening is lower than the
inside opening.
► Insert a sleeve (with a 100 mm, 3-15/16 inch diameter and purchased
locally) through the hole.
Note:
The purpose of the hole's inclination is to promote drain flow.
