Installation I (
new construction
)
1.
For ideal ventilation use, hold the body
of the fan with the exhaust side facing
the desired duct direction.
2.
Place the body of the fan in between
joists in designated area.
3.
If convenient to secure unit to the joist
(otherwise go to step 4), place the unit
against joist and push the fan to the
proper depth and use long screws
(Fig. C).
4.
Add the provided brackets (Fig. D)
to the sides that are not connected
to the joists.
5.
If the brackets are too short to reach the
joist, use the extensions provided (Fig. E).
6.
Attach the duct to the exhaust outlet
of the fan. Secure with duct tape
(Fig. F)
and make sure there is no air leak. Make
sure there are no sharp bends in the duct
line (Fig. G). For 90 degrees angles, use
smooth curves or break into two smaller
angles or curves (Fig. H).
NOTE
For safety and efficiency of the ventilation system,
avoid sharp angles and loose support.
