WHAT COMES IN THE CARTON
To make sure you have everything you need
to install your new whole house attic fan,
unpack the carton and take inventory. The
carton should contain:
(1) Fan assembly
(1) Return grill with (6) fasteners
(1) 1-inch wide x 84-inch long roll of
adhesive-backed foam
(1) Remote controller (Batteries not
included)
(6) Hex head screws for mounting fan
unit to ceiling joists
Step-by-step
installation
A
Proposed fan

Step 1: Select a central
location for the fan
•
Your whole house attic fan is designed for
horizontal mounting on the floor of your attic,
usually above a centrally located hallway.
Note: For vertical installations, the fan should
be mounted between 16-inch OC wall studs
only. For 24-inch OC wall studs, framing will
have to be installed to simulate a 16-inch OC
wall stud situation at the desired fan location.
Installation procedures are essentially the
same as those for a horizontal installation.
•
In the hallway, find the center of the ceiling
by measuring half the distance between the
walls. Mark the spot with a pencil.
•
Drill a hole with a small bit on the ceiling
mark, and push a straight length of wire
through the hole so you can locate it in
the attic. (Illustration A)
Step 2: Investigate
the attic location
•
Go to the attic and find the hole you’ve made
in the ceiling from below.
•
Locate the joist nearest to the hole.
•
Clear the insulation between the joists at
the location of the hole (approximately 1
feet on each side of hole). Wear work
gloves to avoid skin irritation from the
insulation.
•
Check for electrical and other wires or pipes.
If any wires or pipes are in the way, you can
have them moved by a professional or pick
another location to mount the fan.
•
Check the clearance above the fan location.
There must be at least 24 inches between
the top of the fan and the roof. Providing
enough air space above the fan helps
prevent the motors from overheating and
keeps them running efficiently.
•
In addition, make sure that enough clearance
exists for the path of the shutter. To ensure
proper operation, a minimum of 4 inches
clearance is required on the hinged side
of the unit. No framing lumber, truss mem-
bers, utilities, etc. should impede the path
of the shutter.
Warning: Failure to provide sufficient shutter
clearance could result in damage to the
product.

Step 4: Cut the hole
•
Using a keyhole saw or utility knife, cut
between the four corner locations.
Note: If you are cutting from inside the attic,
you may first want to cut a hand-sized hole
at the center to allow for a place to secure
the sheet rock while cutting between the four
corners. This should help prevent the face of
the sheet rock from tearing below.

Step 5: Install the
framing members
•
Depending on the ceiling joist spacing, cut
2X lumber to (2) 14 1/2-inch lengths for
16-inch OC joists or (2) 22 1/2-inch lengths
for 24-inch OC joists.
Note: Verify these lengths with a tape mea-
sure before cutting lumber.
•
Using nails or wood screws (not provided),
install the framing members between the
Step 3: Establish cut-out
location inside attic
Note: If the whole house fan fits through
your attic access opening, the remaining
installation steps can be performed from
inside the attic except the grill installation
(Step 8) and possibly the cutting of framing
lumber. (Step 5)
•
Select the joist bay that has the “centering”
hole which was created in Step 1, provided
that the criteria established in Step 2 are
satisfied.
Note: If ceiling joists are parallel to the length
of the hallway, it is possible that the whole
house fan will not be centered in the hallway
ceiling. Another location may need to be considered depending on personal preferences.
•
Drill two holes at the edges of the joists in
perpendicular line with “centering” hole.
(Illustration B)
Note: Make sure that the perpendicular
distance between joists is approximately
14 1/2 inches for 16-inch OC joists or
22 1/2 inches for 24-inch OC joists.
•

joists with the inside edge flush with the
exposed sheet rock edges. (Illustration C)
•
Optional Step: To help reduce the noise level
of the fan in the “Exhaust Mode” (higher
speeds), install additional 2X framing lumber
above the ceiling joists and framing members
to create a box that extends the fan further
away from the plane of the ceiling and the
grill.
Warning: It is critical to ensure that enough
clearance is available for the fan (Step 2).
In addition, the framed box should be sealed
so that attic air can not be drawn into it
through the joints.
Note: This optional step should help minimize
the possibility of blown-in insulation from
being carried by the airflow and should also
help prevent the insulation from impeding the
path of the shutter. If after this step has been
implemented and the insulation is still moved
by the flow of air, an air dam can easily be
created around the three, non-hinged sides
of the unit using either cardboard or lumber.
This air dam will force the flow of air to travel
up and over the top of the insulation.
Step 6: Mount the fan assembly
•
Using the 1-inch rolled adhesive-backed
foam, cut and apply to the underside of the
flange around perimeter of housing wall. (For
positioning: Edge of foam can be butted
against wall of housing.) Application of the
2
foam minimizes vibration and seals possible
air passages between the living space and
the attic.
•
Using the six pre-drilled holes in the whole
house fan flange, secure the fan assembly to
the ceiling joists and framing using fasteners
provided.
Note: Orientation of the whole house fan
should allow clearance for a fully-open shutter (not only vertical distance above the fan,
but also horizontal clearance at hinged
side of the fan as described in Step 2).
Step 7: Make electrical
wiring connections
•
Refer to “Electrical Requirements” section,
page 3, for information on bringing electric
power 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
electrical wiring box on the side of the fan
housing.
•
Using wire nuts make the following electrical
connections (Illustration D):
•
Hot wire from power supply (typically
black) to the fan’s black wire
•
Common (neutral) wire from power
supply (typically white) to the fan’s
white wire
•
Ground wire from power supply
(typically bare copper) to the fan’s
green wire

Leads (blue, red, & yellow) other than those
previously specified are only to be used for
an optional wall-mounted control. Do not remove insulation from these lead ends unless
installing the optional controller.
Warning: Failure to isolate these leads (blue,
red, & yellow) from each other and from
other conductors, including the metal wiring
box, could result in erroneous unit operation
or possibly damage to the unit.
Note: For more information about the option-
al wall-mounted controller and availability,
call 309-692-6969.

Push the wire connections into the unit’s
wiring box. Secure the cover to the electrical
wiring box.
•
Turn on the switch mounted to the electrical
wiring box.
•
Before leaving the attic, place the attic insulation around the whole house fan.
Step 8: Install the grill
•
Using the six fasteners provided, center and
install the grill over the opening from the
hallway. The fasteners should penetrate the
joists and framing added in Step 5.
Note: It may be necessary to trim the sheet-
rock around the perimeter of the opening to
allow for a flush installation of the grill. If so,
trim 3/4-inch from the edges of the long
sides of the sheet rock opening and 5/8-inch
from the edges of the short sides of the sheet
rock opening using a utility knife.

Step 9: 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 closed.
•
At your home’s breaker box, switch on the
circuit breaker associated with the fan.
•
Insert batteries into remote.
•
Refer to the section entitled WHSP2000
Operating Instructions (page 4) for information on the functionality of the unit. A
condensed version of the operating instructions is located on the back of the remote.
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 adequately vented, the whole house
fan will shut off automatically as a result of fan
motor overload.
•
The WHSP2000 whole house fan requires a
minimum of 2.6 square feet, or approximately 384 square inches, of open attic vent area.
•
Check your attic ventilation system to make
sure that it provides at least this minimum
amount of open vent area. Typically, undereave or soffit vents are installed near the
floor of the attic, and roof louvers, gable
vents, or ridge vents are installed high in
the attic to allow air to escape. These vents
are installed to provide attic ventilation year
round, and when the whole house fan is on,
these vents provide the net free area to
exhaust it.
Remember: When measuring your vents,
obstructions such as louvers and screens
need to be factored into the open area. A
good rule of the thumb is to divide the
vent’s size in half.
ELECTRICAL REQUIREMENTS
Your whole house attic fan runs on standard
115-volt house current. Electrical installation
and wiring of the fan must adhere to the
National Electrical Code and all local codes
that apply, including fire-rated construction.
Wiring the whole house attic fan itself is a
simple procedure that most homeowners can
accomplish (see Step 7, page 3). However,
bringing the electrical power supply to the fan
requires a higher level of electrical knowledge
and skill. If you are not experienced at installing residential electrical wiring and/or are not
familiar with all national and local electrical
codes, you should hire a qualified electrician
to do the wiring for you.

OPERATING INSTRUCTIONS
•
To start the unit, press “START.” The fan will
resume the speed setting that was last selec-
ted as indicated by the corresponding LED
which lights up momentarily when the
“START” button is depressed.
Note: Upon startup, it will take approximately
15 seconds (time for shutter to completely
open) before the processor is capable of
accepting signals from the remote control
transmitter.
•
To change speeds, press the “START” button
until the desired speed is selected as indicated by the corresponding LED on the
remote control.
Remember: It will only be possible to change
speeds after the shutter (inside of the attic)
has reached the fully open position.
•
To use the timer feature, depress the “SET
RUN HOURS” button until the desired run
time is selected as indicated by the corresponding LED which lights up momentarily
when the button is depressed. When the unit
is turned off and then back on, the timer feature defaults to manual mode.
Note: The unit must be running and the shut-
ter must be fully open before the timer feature can be activated.
•
To stop the unit at any time, depress the
“STOP” button. This interrupts power to the
fan motors and sends power to the shutter
drive motor. It will take approximately 15
seconds for the shutter to completely close
and for the processor to recognize signal
transmission from the remote control.
•
In order to conserve battery power, an 8-second timeout feature has been integrated into
the remote control software. After 8 seconds
has elapsed from the last signal transmission, any subsequent signal transmitted (by
depressing either the “START” button to
change speeds or the “SET RUN HOURS” button to change the timer selection) will be a
duplicate of the current setting. The button
used to activate the desired setting change
will need to be depressed consecutive times
until the corresponding LED of the desired
setting momentarily lights up.
