Installation Guide

3
• Optional - From the attic, apply 1
1
/
2-inch
wide adhesive-backed weather stripping to
the bottom edges of the fan frame that
make contact with the joists. This helps
reduce vibration noise.
• Set the fan onto the joist, making sure the
saddle brackets slide down onto the joist.
Step 8: Make electrical
wiring connections
• Refer to “Electrical Requirements” section,
page 4 for information on bringing electric
po
wer to fan location.
• At your home’s breaker box, turn off the
electrical power to the circuit associated
with the fan. Do not turn on the power to
this circuit until you have completely
finished the fan installation.
• From the attic, remove the cover from the
fan’s wiring box. Using twist-on electrical
connectors, connect the black wire from the
power supply to the fan’s black wire.
Connect the white wire from the power
supply to the fan’s white wire.
(Illustration G)
• Connect the ground wire from the power
supply to the screw provided on the back
of the wiring box.
• Push the wire connections into the fan’s
wiring box. Replace the box cover and
screw it closed.
Step 9: Secure mounting
brackets to the joist
• From the hallway, center the fan assembly
over the shutter cutout in the ceiling.
• Use the lower hole of the saddle-mounting
bracket as a guide to drill a
1
/
4-inch hole
through the joist. Secure the mounting
bracket to the joist with a 2
1
/
2-inch-long
bolt and nut.
• Follow the same procedure with the lower
hole of the mounting bracket on the other
side of the fan frame.
Then drill and bolt
the upper holes of the brackets on both
sides.
Step 10: Mount the shutter
• Using the chain connector provided, attach
the short pull chain from the fan’s on-off
s
witch to the pull chain extension.
• Position the shutter in the ceiling cutout so
the pull chain passes through the chain
guide in the shutter
.
(Illustration H)
• Mark the location of the shutter mounting
holes with a pencil.
Remove the shutter.
• Use a
3
/
16-inch bit to drill the four holes on
the corners of the shutter frame. Don’t drill
holes for the two screws that go into the
joist.
• Insert plastic anchors into the four drilled
mounting holes.
• Reposition the shutter in the cutout and
fasten it in place with two screws in the
joist and four screws in the plastic anchors.
• Cut the pull chain to the desired length.
Attach the bell connector to the end of
the chain.
Step 11: Install the
skirting material
• From the attic, you will notice gaps
between the ceiling sheet rock and some
sides of the fan frame. These gaps must
be blocked off with the cardboard skirting
material provided in order to have a sealed-
off vacuum box for the fan and shutter.
• Cut the skirting material to size with a
utility knife. Position it on the outside of
the fan frame so the lower edge is flush
with the ceiling sheetrock.
• Attach the skirting material by drilling
1
/
8-inch pilot holes and then fastening with
the screws provided. Or you can use a
stapler. (Illustration I)
• The skirting material can be notched for the
incoming power line. Use duct tape to join
cutout pieces of skirting or fill small gaps.
• Replace the insulation around the fan
frame.
Step 12: Attach the fan blade
• Attach the fan blade to the motor shaft.
The setscrew on the blade should be on the
flat side of the motor shaft. Position the fan
blade near the end of the shaft, not up next
to the motor.
• The hub of the fan blade should face up
into the attic.
• Tighten the setscrew securely with a
1
/
4-inch allen wrench.
• Slowly rotate the blade one full revolution
by hand to make sure there are no
obstructions.
If there are an
y obstructions,
remove them and recheck the fan
clearance.
Step 13: Operate the fan
• Open windows and interior doors of rooms
to be ventilated by the fan.
•
If you have a fireplace, make sure the flue
is c
losed.
• At your home’s breaker box, switch on the
circuit breaker associa
ted with the fan.
• Pull once on the pull-chain to operate the
fan at high speed. Pull again to operate the
fan at low speed. Pull once more to turn
the fan off.
ATTIC VENTILATION REQUIREMENTS
In order for the whole house fan to work
properly, adequate ventilation is needed
to exhaust the hot air from the attic that
the fan pulls into the attic from your
home’s living space. If your attic is not
shaft, and put it aside to prevent it from
being damaged.
• Note that the setscrew is tightened against
the flat side of the motor shaft.
(Illustration E)
Step 7: Position the fan
assembly on the ceiling joist
• Using the pre-drilled holes provided, mount
the two metal saddle brackets to the inside
of the fan frame with the six 1
1
/
4-inch-long
bolts and nuts provided.
(Illustration F)
• Pass the fan assembly to a helper in the
attic through the shutter hole. If easier, you
can carry the assembly up to the attic.
