Note
- Check that each air supply/exhaust pipe
A catches on all four prongs of its pipe
mounting plate. (If a prong has not caught,
the pipe will press against the back of
the Lossnay unit and the shutter may not
operate properly.)

Note
- Securely screw air supply/exhaust pipes A
and B together all the way.(If they are not
screwed together tightly, water inltration
may occur.)
- Caulk the connections between air supply/
exhaust pipes A and B as shown above.
Attaching the mounting plate
1)Attachthemountingplatetothewall
provisionally using a single loosely attached
screw.
2) Hang a plumb bob to make sure that the
looselyattachedmountingplateishorizontal
(towithin1°).
3) Attach eight wood screws at locations where
thewallcontainsreinforcingmaterial.
Note
- Attach the two locations near the catches
underneath the catches.(See diagram above.)
- To attach the plate to a concrete wall, use off-
the-shelf concrete screws.

2) Cut air supply/exhaust pipes A perpendicular
to the pipe axis at the length shown in the
gureabove.

3) Prepare the air supply/exhaust pipes.
- Insert each air supply/exhaust pipe A
into a pipe mounting plate and rotate it
counterclockwiseuntilthefourprongscatch.
Caution
- Mount air supply/exhaust pipes A so that
the UNDER mark is at the bottom. After
mounting the pipes, check that they slope
downward as they go outside. (If they do
not, rainwater may inltrate the wall and the
shutter may not operate properly.)
