1. Insert the suspension bracket into the fan body. If spacing
between joists is 21 1/4” to 23 1/2” (54 cm to 59.7 cm) connect
suspension brackets I and II (Fig. 1).
2. Mount the fan body to joist using the suspension brackets and
long wood screws (Fig. 2-1 or Fig. 2-2 and 2-3).
CAUTION
Dimension “B” should allow for thickness of ceiling board
used in your application. Do not ush mount to joist. Flange
should be ush with ceiling board (Fig.2-1a)

3. Refer to wiring diagram on page 4. Remove the junction box
cover. Using wire nuts, connect house wires to ventilating fan
wires: black to black; white to white; green to green. Replace
the junction box cover (Fig. 3).
CAUTION
If your house wires do not match these colors, you must
determine what each house wire represents before connect-
ing and you may need to consult an electrical contractor to
determine this safely. Mount junction box cover carefully so
lead wires are not pinched.
4. Install a circular dust and secure it with duct tape or clamps.
5. Finish ceiling work. Ceiling hole should be ush with the edge
of the ange. Do not ush mount to joist. Flange should be
ush with ceiling board. See dimension for ceiling hole on page 3
(Fig. 4). If a joist is present, insert long wood screws through ange
and through ceiling to secure fan to joist.
6. Pinch mounting springs and insert into narrow rectangular slots
inside the fan housing next to the fan motor (Fig. 5).
7. Turn on electricity at breaker box after nishing installation.

installation II (IN EXISTING CONSTRUCTION)
7
Installing the fan body in an existing building requires an accessible area (attic or crawl space) above the
planned installation location and existing duct and wiring.
A) To install the fan body, follow the procedures described in Installation I.
1. Take the following precautions before installation:
Check the area above installation location to be sure that:
Duct work can be run and the area is sufcient for proper ventilation;
Wiring can be run to the planned location;
No wiring or other obstructions can interfere with installation.
Inspect ductwork and wiring before proceeding with installation.
Plan suitable location for fan body (next to ceiling joist). Do not ush mount ange to ceiling joist.
Before installation, provide inspection and future maintenance access at al location that will not
interfere with installation work.
2. Remove ceiling section using dimensions provided on page 4. Be careful to cut the hole exactly.
If the hole is too big, the fan grille will not hide it.
3. Install fan body.
4. Continue with steps 3-7 of Installation I on page 6 to complete installation work.
B) Installation from accessible area (e.g. attic) above fan location:
1. Inspect duct work and wiring before proceeding with installation.
2. Remove ceiling section using dimensions provided on page 3.
3. Install fan body.
4. Continue with steps 3-7 of Installation I on page 6 to complete the installation work.
