INSTALLATION
1. Remove motor plate from housing
by pushing down on rib in plate
while pulling out on side of housing.
Motor plate may also be removed by
inserting a straight-blade screw driv-
er into slot in housing and twisting
screw driver (Figure 1).
2. Remove wiring cover from housing
by pulling straight out. Unit is
shipped ready to wire through the
top of housing. To wire through the
side, bend housing flap to cover top
hole and expose side hole. DO NOT
BREAK OFF FLAP. If flap breaks,
plug unused hole using standard
electrical hole plug (Figure 2).
3. Turn off electrical power at service
entrance and connect power cable
to housing using appropriate con-
nector. Wire black to black, white to
white, green to green or bare wire.
Push all wiring up into corner
of unit and replace wiring cover.
Make sure cover holds housing flap
in place against side or
top of housing.
Do not allow wires
to extend outside of the
wiring box. Wire left exposed will become
pinched or cut when motor
plate is installed. Electrical shock
may result (Figure 3).
4. Choose the location for your
fan. For best performance, use the
shortest possible duct run
and a minimum number of elbows.
For wall installations: position unit so
damper flap closes when unit is off.
5a.
New Installation prior to finishing
the ceiling or wall:
Make sure the housing will be flush
with the finished ceiling or wall.
Slotted tabs are provided to locate
housing flush with 1/2" ceiling or wall
material. Bend tabs outward 90º
(Use a screw driver if desired) and
position housing so that tabs rest
against bottom edge of joists (or
front of stud). Nail housing to joist or
stud using four nails to ensure a
solid, quiet installation. Ceiling instal-
lations: Tabs on opposite side of
housing can be bent outward to rest
on top of 1/2" ceiling material and
provide extra stability (Figure 4).
5b.
Replacement Installation:
Position housing so that it is
centered in existing opening. Make
sure the housing will be flush with
the finished ceiling or wall. After
making electrical and ductwork con-
nections (see steps 4, 5 and 6), nail
housing in place. Drive nails through
the housing where indicated by
arrows (Figure 5).
5c.
New Installation in an existing
ceiling or wall:
From above ceiling or behind wall,
position housing against stud or
joist. Trace outline of housing on
ceiling or wall material. (Fig. 6) Set
housing aside and cut opening.
Place housing in opening such that
its bottom edge is flush with the fin-
ished ceiling or wall. 1/2" ceiling or
wall material: Bend tabs outward 90º
(use a screw drive if desired) to rest
on top of ceiling or wall material and
provide extra stability. Nail in place
using four nails to ensure a solid,
quiet installation (Figure 7).
6. Install 3" round duct onto damper/
duct connector. If rigid ductwork is
used, its seam should be positioned
at top of damper/duct connector.
Tape the joint and extend ducting to
a wall cap or roof cap. Make sure
the damper operates freely. Ceiling
or wall can now be finished.
7. Replace the motor plate removed
in step 1. Insert two motor plate tabs
into slots in housing and then pivot
motor plate up until the third tab on
plate snaps into matching slot in
housing. Make sure tabs hold motor
plate securely in place. Plug
in motor (Figure 8).
8. Squeeze grill springs together
and insert springs into slots in motor
plate (Figure 9). Push the grill up
against ceiling or wall (Figure 10).
Parts Replacement
If replacing parts, do so with properly
selected components which duplicate the
original parts correctly. Incorrectly sized
