ELECTRICAL REQUIREMENTS
This fan requires a 120 volt, 3.3 amp uninterrupted electricity supply. We strongly recommend
providing a dedicated circuit for this fan.
This fan has two factory-installed, 10 ft. power cords. One originates at the control box, and the other at
the fan-mounted electrical box. Consider these lengths when choosing a location for this fan. Depending
on the location of existing outlets in the attic, the installation of an additional outlet may be required. Con-
sult an electrician if necessary.
All wiring and connections must be made according to this manual and acceptable wiring standards. All
local codes must be followed.

The 2.5e WHF hasbeen designed to t on top of a 14½"
x 22½" wall or ceiling opening. Since most modern
houses have been built with either 16" or 24" on-center
(O/C) spaced joists or studs, a simple "box" is construct-
ed in the wall as ceiling, as shown at right in Figure 1.
NOTE: There are two different installation methods de-
termined by how the 2.5e’s fan assembly will be moved
into the attic. Follow the instructions that apply to your
install.
If there is an existing attic access large enough for
the fan assembly to t through:
16” O/C Framing
1. Install two 14½" cross pieces creating a box with inside dimensions 14½" x 22½".
2. Cut out dry wall inside the framed box.
24” O/C Framing
1. Install two 22½" cross pieces creating a box with inside dimensions of 14½" x 22½".
2. Cut out dry wall inside the framed box.
If the fan assembly must t through the hole that is framed for it:
16” O/C Framing (shown in Figure 2 below)
1. Cut out the dry wall between the joists to create a 23” x 14½" rough opening.
2. Fit the fan assembly through the rough opening and into the attic.
3. Install two 14½" cross pieces creating a box with inside dimensions of 14½" x 22½". Make sure each
cross piece partially covers the drywall cut out. Approximately ¼” of each cross piece should be visible
from below.
24” O/C Framing (shown in Figure 3 below)
1. Cut a 23” x 14½" opening in the dry wall, use an existing joist as the 23” long side.
2. Fit the fan assembly through the rough opening and into the attic.
3. Install cross pieces creating a box with inside dimensions of 14½" x 22½". Make sure each cross piece
partially covers the drywall cut out. Approximately ¼” of each cross piece should be from below.

Position the 2.5e damper enclosure on top of the joists
so that the damper doors are aligned with the framed
rough opening, as shown at right in Figure 4. Make sure
there is easy access to the electrical box located on the
side of the unit.
The actuator end of the damper box has two “key holes”
which are used to attach the damper box to the joists.
Mark the location of the “key holes” on the joists by plac-
ing the damper box over the rough opening. Remove
the damper box and fasten two of the provided wood
screws so that the screw head is slightly above the joist.
Position the damper box over the “key holes” and slide
to lock into position. Use the remaining screws to attach
the opposite side of the damper box.
If installing the damper vertically in a wall, frame a box with the same dimensions as above. However, use
longer wood screws than those provided (at least 1½˝ ) to mount the damper to the framing, and make
sure the damper door(s) open about their vertical axis. Also, consider bracing the underside of the damper
with additional framing.
Use a good quality latex caulk to seal all wood-to-wood and wood-to-metal joints to create an airtight
enclosure. This is important to ensure that all air drawn in by the fan will be from inside the house.
From below, attach the interior grille to the joists with the included wood screws.
INSTALLATION: BACKDRAFT DAMPER
Figure 4
INSTALLATION: BACKDRAFT DAMPER COLLAR
First, remove the two screws holding damper collar in place for shipping and ip collar.
Then, position the collar over the damper box opening and fasten the two together using 2 screws in the
holes at the top of the collar as shown below in Figure 5.
Next, as shown below in Figure 6, stretch the collar until the bottom 2 holes line up with the coorespond-
ing holes on the damper box body and secure the two peices together using 2 screws at these holes.
Finish fastening the damper box and collar together by using screws at each remaining hole.

INSTALLATION: FAN & DUCT
Attach 4 lengths of the provided chain to the the attic’s rafters at four locations using wood screws (NOT
provided) screwed through a chain link. Alternatively, eye bolts (also NOT provided) can be anchored into
the rafters and additional S-hooks (also NOT provided) used to attach the chain thereto
Attach the 4 provided S-hooks to 4 of the D-rings attached to the fan housing. Hang the fan assembly
from the rafters using these S-hooks and the 4 lengths of chain just installed as shown below in Figure 7.
When hanging the fan assembly, adhere to the following guidlines:
• Do not hang the fan using fewer than 4 lengths of chains or eye bolts; all four attachment points are
necessary to support the fan’s weight and to eliminate any swaying motion.
• Ensure that the fan is as level as possible.
• Blocking this fan’s exhaust can cause it to fail prematurely. Keep the area in front of the fan as unob-
structed as possible: no object should be closer than 24” to the face of the fan.
Next, slide one end of the exible ductwork over the backdraft damper’s collar and fasten it thereto using
4 of the 8 provided self-tapping sheet metal screws.
Then, gently bend the ductwork to a 90  angle and slide the free end over the fan assembly’s collar and
fasten it thereto using the remaining 4 provided self-tapping sheet metal screws.
Figure 8 at the top of the next page describes the two ductwork conntections. Adhere to the following
guidelines when attaching the ductwork to the backdraft damper and fan assembly:
• Make sure to maintain the full diameter of the ductwork through the bend; this provides adequate
airow and helps minimize noise.
• Avoid sharp bends in the ductwork or contact with metal xtures, pipes, or conduits.
• The section of ductwork immediately before the fan should be as straight as possible.
• If necessary, the ductwork can be supported under the bend using extra chain wrapped with a protec-
tive material (e.g. carpet).
KEEP AIRSTREAM AS UNOBSTRUCTED
AS POSSIBLE

Once the fan assembly is balanced and secure, use pliers to close all of the S-hooks to ensure stability,
and tape down all unused D-rings to avoid excess rattling.
Then, use the provided duct tape to seal the joints between the ductwork and backdraft damper, and the
ductwork and fan assembly.

INSTALLATION: WIRING & CONTROLS
The standard control package included with this fan contains: the control box; 1 hardwired wall switch; 1
mounting bracket for the wired switch; 50 ft. of red CAT5 cable; and, 10 ft. of green CAT5 cable.
First, locate the control box mounted on the side of the damper. Look for a series of 5 RJ45 ports on one
side. These ports are labeled with the following label:
Next, connect the green CAT5 cable into the electrical box mounted on the fan assembly using either of its
RJ54 ports. Run the cable down to the control box and connect its free end to the green FAN port. This
cable is unshielded: Do not run it parallel to the fan assembly’s power cord.
Connect the red CAT5 cable to the red W/S port. Then, run the cable through the attic and down a wall
to the desired location for the hardwired wall switch. Note: This cable is low-voltage but unshielded.
Building Codes require unshielded low-voltage wiring to be run through shielded conduit.
Because a hardwired switch is necessary for providing technical support, the wall
switch included with this fan MUST be connected to the fan’s control box regard-
less of whether or not it will be installed in a wall. FAILURE TO CONNECT THE
HARDWIRED WALL SWITCH WILL VOID THIS FAN’S WARRANTY! If it is
not desired to be installed in a wall, the hardwired switch can be connected to the
control box and left in the attic with the CAT5 cable kept spooled.

INSTALLATION: WIRING & CONTROLS, cont.
Using the provided mounting bracket as a template, trace an outline on the wall where the swich is de-
sired. Following this outline, cut a hole for the mounting bracket, place it inside, and secure it with the lock-
ing tabs by tightening the silver screws. Then, connect the free end of the red CAT5 cable to the port in
the back of the wall swich. Set the switch in place and secure its face plate to the mounting bracket using
the attached white screws.
Finally, plug each of the two power cords (one from the fan assembly and one from the control box) into
120-volt outlets with uninterupted power.
For reference, Figure 9 below describes this fan’s and its accessories’ general wiring scheme.
