(Otherwise, the back of the product is
pushed, causing shutter operation failure.)
- Attach the pipe in such a way that the "B"
mark on the mounting plate matches the "B"
mark on the flange part.
- If the air supply/exhaust pipe is not
downward slanted, drain water may reflux or
rainwater may come in.
8. Attach the mounting plate.
(a) Put the air supply/exhaust pipe through the
wall hole.
(b) Use one wood screw to temporarily secure
the mounting plate. (Tighten the screw at
the end.)
(c) Attach one unit fixing screw to the mounting
plate for hanging the unit.
(d) H ang a weight and check the level of the
mounting plate (slope within 1°). (If the unit
