INSTALLATION INSTRUCTIONS
CAUTION:
MAKE SURE POWER IS SWITCHED OFF AT
SERVICE PANEL BEFORE STARTING INSTALLATION.
SECTION 1
Preparing the Unit
1. Unpack fan from the carton and confirm that all pieces are
present. In addition to the unit you should have:
1 - Grill with Light Lens
4 - Mounting Rails
1 - Instruction/Safety Sheet
2. Remove the two hex nuts holding the light reflector in place.
Keep the reflector and nuts in the carton until needed so they
do not get damaged or lost. (Figure 1).
Figure 1
3. Remove the fan's venturi assembly, which is secured in place
with one screw through the venturi (Figure 2). Keep the venturi
assembly and the grill in the carton until needed so they do
not get damaged or lost.
Figure 2
WARNING:
DO NOT INSTALL OVER A TUB OR MOUNT IN
A SHOWER STALL ENCLOSURE.
4. Choose the location for your unit. To ensure the best air and
sound performance, it is recommended that the length of
ducting and the number of elbows be kept to a minimum, and
that insulated hard ducting be used. Larger duct sizes will
reduce noise and airflow restrictions. This fan will require at
least 7" of clearance in the ceiling,
and will mount through drywall
up to 3/4" thick. The fan mounts
between 16" on center joists using
the 4 provided mounting rails.
5. Remove the electrical knockouts
using a straight-blade screw
driver (Figure 3).

SECTION 2
New Construction
1. Install the rails on the housing and position the housing next
to the joist. Line up housing so it will be flush with the finished
ceiling. Secure the ends of the rails with screws or nails (not
included) to the joists and slide housing into final position
(Figure 4).
Figure 4
SECTION 3
Existing Construction
1. Set housing in position between the joist and trace an outline
onto the ceiling material (Figure 5). Set housing aside and
cut opening, being careful not to cut or damage any electrical
or other hidden utilities. Install the rails on the housing and
position the housing in the previously cut hole so that it is
flush with the finished ceiling. Secure the ends of the rails
to the joists with screws or nails (not provided) to ensure
proper installation (Figure 4).

SECTION 4
Ducting
CAUTION:
AND NATIONAL BUILDING CODES.
1. Remove any tape that might be holding the damper in place.
Connect the ducting to the fan's duct collar (Figure 6) and
secure in place using tape or screw clamp. Always duct the
fan to the outside through a wall or roof cap.
