“CSS” SERIES SHUTTER INSTALLATION, continued
ELECTRICAL WIRING
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.
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
FOR HIS SUGGESTIONS.
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
STEP 6. Build a platform to support the fan using
lumber, plywood or other suitable 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. 6).
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 the plenum. DO NOT REPLACE SCREWS.
This is to permit the fan to “float” on the rubber
mount which helps reduce noise. (See fig. 8).
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).
