(100-105 mm, 3-15/16 - 4-9/64 inch for WL12, 15 model) in the wall in the
piping direction, at the position shown in the diagram on the left.
► The hole should incline so that the outside opening is lower than the
inside opening.
► Insert a sleeve (with a 75 mm, 2-61/64 inch diameter and purchased
locally) through the hole. (100 mm, 3-15/16 inch diameter for WL12,
15 model)
Note:
The purpose of the hole's inclination is to promote drain flow.
