mounting plate.
(a) Insert the air supply/exhaust pipe to the
mounting plate.
(b) Turn the pipe counterclockwise to hook the
pipe mounting plate with the tab.
(c) Check that the air supply/exhaust pipe
is downward toward the outdoor side, as
shown in the following figure.
Note
-
Check that all four tabs catch the flange.
(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 pipe mounting plate.
-
If the air supply/exhaust pipe is not
downward slanted, drain water may reflux or
rainwater may come in.
10. 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) Hang a weight and check the level of the
mounting plate (slope within 1°). (If the unit
is inclined, water may spill from the drain
pan.)
(e) Use four wood screws to secure the
mounting plate to the position where
reinforcement is provided inside the wall.
