installation. Use a utility knife or sheetrock saw and
carefully cut the shutter opening. (See fig. 1).

STEP 2. From the attic side cut the ceiling joist 1

back from shutter opening. This is to accommodate
additional framing to support the joists that have
been cut. (See fig. 1).

STEP 3. Frame the opening using lumber EQUAL

TO THE EXISTING JOISTS. Attach the new framing to
the existing joists. Before fastening, make sure that
the existing joists that were cut DO NOT sag below
the uncut joists and new framing. (See fig. 2).

STEP 4. If additional framing or blocking is needed to

support the shutter, install it at this time. (See fig. 4).

STEP 5. Remove the two (2) screws that secure

the fan to the plenum. Pass the fan and plenum into
the attic through the framed opening in the ceiling
and set them aside at this time.

STEP 6. Build a platform to support the fan using

lumber, plywood or other material a minimum of

3

/4" thick. The platform must be constructed so that
it supports all four sides of the fan, and should be
wide enough to prevent Attic Air from being drawn

into the fan. With some combinations of fan and
shutter, a portion of the opening may be blocked
by the platform. This will not effect the efficiency of
the fan. Fasten the platform to the joists and new
framing. (See fig. 2).

STEP 7. Center the plenum on the platform and

toe nail it in place. NOTE: WHEN TOE NAILING

PLENUM TO PLATFORM MAKE CERTAIN THAT THE
SIDES OF THE PLENUM REMAIN STRAIGHT AND
SQUARE OR THE FAN WILL NOT FIT PROPERLY.

STEP 8. To prevent Attic Air from entering the

plenum, tape all of the joints of the new framing,
platform and plenum with duct tape or aluminum
foil tape.

STEP 9. Place the fan on the plenum making sure

that the rubber isolation mount is in place between
the fan and plenum. DO NOT REPLACE SCREWS.
This is to permit the fan to “float” on the rubber
mount which helps reduce noise. (See fig. 4).

STEP 10. Install the flush mounted ceiling shutter

into the ceiling opening using the screws provided.
Caution should be taken not to effect the free
operating action of the shutter. (See figs. 3 & 4).

will be the center of the fan. With a pencil trace
around the template. Repeat this procedure on the

1

exact opposite side of the joist. Drill a

/4" hole at each

corner of the pencil lines. YOU SHOULD HAVE EIGHT

(8) HOLES. From directly below the attic, check to be

sure that the location is correct.

STEP 2. Return to the attic, and using a utility knife

or sheetrock saw carefully cut the shutter opening
following the pattern on both sides of the joist. (See

fig. 5).

DO NOT REMOVE THE SHEETROCK

FROM THE CENTER JOIST.

STEP 3. Frame the opening using lumber EQUAL

TO THE SIZE OF THE EXISTING JOISTS. (See fig. 6).

STEP 4. If the opening is less than the distance

between the joists, fasten supports between the new

framing along the edge of the opening. (See fig. 8.).

STEP 5. Remove the two (2) screws that secure the

fan frame to the plenum. Pass the fan and plenum into
the attic through the framed opening in the ceiling.*
Set them aside at this time.

STEP 10. Install the flush

mounted ceiling shutter into
the ceiling opening using the
screws provided. Caution
should be taken not to effect
the free operating action of

the shutter. (See fig. 8).

REFER TO THE "ELECTRICAL

WIRING" SECTION BELOW.

This fan requires a 120 Volt AC. power source with

at least 15 amp capacity. All electrical wiring must be in

accordance with local electric codes. Use 12 gauge or
larger for all the fan wiring.

STEP 1. Get professional help If you are not familiar

with electrical wiring and local wiring codes.

STEP 2. Turn OFF power at the Fuse/Circuit Breaker

Box before wiring. (See safety rules on pg. 1).

STEP 3. WARNING: TO REDUCE THE RISK OF
ELECTRICAL SHOCK AND DAMAGE TO THE FAN
MOTOR, DO NOT USE THIS UNIT WITH ANY SOLID
STATE OR VARIABLE SPEED CONTROL DEVICE.

STEP 4. For ease of electrical wiring installation it is

recommended that a junction box is mounted in the close
proximity of the fan motor. This should be mounted to a
ceiling joist within a few feet of the fan. REFER TO THE

WIRING DIAGRAMS (figs. 9 & 10) BEFORE STARTING

INSTALLATION.

STEP 5. Select a wall in the structure in a convenient
location and as close to the fan as possible, to mount
the switch that will operate the fan. Once selected, cut a
rectangular hole in the wall to mount a standard electrical
box. This hole should be next to a stud and at the height
of the standard wall switches throughout the structure.

ELECTRICAL WIRING

STEP 6. Once this hole is cut, and before the electrical

box is mounted inside the wall, return to the attic space
and drill at least a 1" diameter hole in the wall top plate
directly above the location where the hole was cut in the
wall.

STEP 7. Feed the electrical wire through the 1" hole in

the top plate until the wire extends down through the wall
to the point it can be brought through the hole in the wall
at the switch location. Working from the switch location,
pull at least 18" of wire through the switch hole.

STEP 8. Feed the wire through the top hole of the

switch box making sure that the wire is anchored to the
box correctly, and insert the box into the rectangular
hole. When the box is installed correctly, the sides of
the box should be flush with the outside surface of the
sheetrock and the box must be secured to the stud.

NOTE: SINCE THERE ARE VARIOUS TYPES OF

ELECTRICAL BOXES THAT CAN BE USED,

CONSULT YOUR LOCAL ELECTRICAL SUPPLIER

STEP 9. Return to the location of the junction box

and insert the opposite end of the wire from the switch
through one of the holes in the side of this box. After the
wire is inserted and anchored properly, the wire may be

cut off leaving approximately 12" inside the junction
box. (See fig. 10).

STEP 10. Go to the fan motor and connect the wires

as shown in appropriate wiring diagram. (See fig. 9).

Route the wire from the motor through the junction
box, anchor securely, and cut leaving approximately
12" in the box. (See fig. 10).

STEP 11. For the power source, it will be necessary

to route from the fuse/circuit breaker box to the
junction box in the attic space. To accomplish this, it
will be necessary to add a circuit breaker. An alternate
method is to use an existing electrical source already
in the attic space. With either method, route this wire
to another hole in the junction box and cut off leaving
approximately 12" of wire in the box. YOU SHOULD
NOW HAVE THREE SEPARATE LINES (WIRES) IN THE
JUNCTION B0X, ONE FROM THE SWITCH LOCATION,
ONE FROM THE FAN MOTOR AND ONE FROM THE
POWER SOURCE.

STEP 12. Using wire nuts connect all wires as

shown in the wiring diagram. It will be necessary to cut
off some of the excess wire in the switch and junction
boxes since these wires must be placed inside these
boxes with the covers anchored securely in place.
When the switch is installed in the switch box BE SURE

THAT THE WALL SWITCH IS IN THE OFF POSITION.

Fig. 9

Fig. 10

STEP 13. Return to the attic. MAKE CERTAIN THAT
THE FAN BLADES ARE CLEAR AND THAT NO WIRES
OR OTHER OBSTRUCTIONS ARE NEAR THE BLADES.

STEP 14. Verify all electrical connections. Switch

power ON at the Fuse/Circuit Breaker Box.

NOTE: WINDOWS IN AT LEAST ONE ROOM OF
STRUCTURE MUST BE OPEN BEFORE TESTING THE
FAN.

STEP 15. TESTING THE FAN. (See fig. 9). Turn

the switch on to High, allow the fan to run for several
seconds, then turn the switch to Low.

STEM 16. With the fan operating, return to the attic
and observe the fan. If the V-Belt is vibrating, turn
OFF the fan, and switch the power at the Fuse/Circuit
Box to the OFF position. See the SAFETY RULES on
page 1. Move the fan spring to the end hole of the
motor-mounting plate. (See page 7). After repositioning
the spring, switch the power at the Fuse/Circuit Breaker
Box to the On position. Re-test the fan.

STEP 17. After testing, replace the insulation around
the plenum and new framing.
