5. Cutting air supply/exhaust pipes
Measure the wall thickness. (If the wall is more
than 300 mm thick, use the provided air supply/
exhaust pipe B). (See page 3, section 3, for
mounting instructions.)
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.)
6. If the wall is more than 300 mm thick
Cut air supply/exhaust pipes A2 in keeping with
the cutting dimensions of step 2 (wall thi
30 mm).
7. Secure the air supply/exhaust pipe to the
mounting plate.
(a) Insert the air supply/exhaust pipe A to the
mounting plate.
(b) Turn the pipe counterclockwise to hook the
pipe mounting plate with the tab.

3. Attach the pipe mounting plate to the air
supply/exhaust pipe A.
(a) Make sure to insert the air supply/exhaust
pipe A deeply to the groove of the pipe
mounting plate.
(b) Use the included aluminum tape (large) to
wrap around the connection section between
the pipe mounting plate and air supply/
exhaust pipe A to properly secure it. If it is
not properly secured, drain water may leak.
4. Apply caulking between the pipe mounting
plate and pipe connection section.
Apply caulking on the connection section
between the pipe mounting plate and air supply/
exhaust pipe from inside.
Note
-
Without caulking, rainwater comes in.
-
After applying the caulking compound,
flatten the surface.
-
Do not apply caulking compound thicker
than the pipe mounting plate. (Otherwise,
drain water is not discharged.)
