WARNING – TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
Use this unit only in the manner intended by the
manufacturer. If you have questions, please contact
the manufacturer.
Before servicing or cleaning unit, switch power off at
service panel to prevent power from being switched
on accidentally.
Installation work and electrical wiring must be done
by qualified person(s) in accordance with all applica-
ble codes and standards, including fire-rated con-
struction.
Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of fuel
burning equipment to prevent back drafting. Follow the
heating equipment manufacturer’s guideline and safe-
ty standards such as those published by the National
Fire Protection Association (NFPA) and the American
Society for Heating, Refrigeration and Air Conditioning
Engineers (ASHRAE), and local code authorities.
When cutting or drilling into wall or ceiling, DO NOT
damage electrical wiring and other hidden utilities.
CAUTION – For general ventilating only, DO NOT
use to exhaust hazardous or explosive materials and
vapors.
CAUTION – This unit has an unguarded impeller.
DO NOT use in locations readily accessible to people
or animals.
Your whole house fan will operate only on 120 Volt,
A.C., 60 Hz (cycle) current.
Permanent THREE WIRE (grounded) wiring must
be used. DO NOT USE AN EXTENSION CORD.
To avoid risk of electrical shock, fire and other
injuries DISCONNECT MAIN POWER SUPPLY prior
to installation.
This fan is to be mounted in a location where the
entrance of drawn in water (rain) is unlikely.
If shutter is removed for servicing, replace before
normal operation.
WARNING: TO REDUCE THE RISK OF FIRE OR
ELECTRICAL SHOCK DO NOT USE THIS FAN
WITH ANY SOLID STATE FAN SPEED CONTROL
DEVICE.
Do not operate this fan in areas where gas or oil-
fired equipment are in operation.
Wear safety goggles when drilling, hammering or
cutting materials.
READ AND SAVE THESE INSTRUCTIONS!
INSTALLATION AND OPERATION
IMPORTANT: Carefully read these instructions
before you install or operate your new whole house
fan. Proper installation is important to achieve max-
imum cooling efficiency. It is necessary to provide
adequate ventilation to meet minimum exhaust
requirements. This prevents pressure build-up in
the attic which will reduce the fan's efficiency. Refer
to the ventilation work sheet on the back page of
this instruction sheet to determine the exhaust air
requirements.

TRIANGLE’S COMFORT AIDE fans are easy to install
using ordinary hand tools. It is not necessary to cut any ceiling
joists or build any wood frames. The motor and two-speed
switch are pre-wired at the factory so all you have to do is hook
it to a 120 volt AC power source with 5 amp capacity. Follow
these easy step-by-step instructions and you will have a pro-
fessional installation.
LOCATION OF FAN - The most logical place to locate your
WHOLE HOUSE FAN is near the central part of the house.
NOTE - if hall area is chosen, it must have a minimum 32"
width for the 24" fan; 35" width minimum for the 30" fan. Check
attic area to be certain there is adequate clearance above the
fan. Minimum space should equal blade diameter. Inspect the
area where the fan is to be installed. The area must be free of
electrical wiring and pipes.
STEP 1. After installation site has been selected for the fan,
remove insulation from area and select a ceiling joist or roof
truss to be the center line of the fan. Use the shutter carton to
make a template.*Use the dimensions listed for your shutter
as shown on the carton. (FIG. 1) Repeat this procedure on the
other side of the middle joist. Drill small holes at each corner
of the area marked on the ceiling. CAUTION: The shutter hole
must equal the “fits hole” dimensions that appears on the shut-
ter carton. Double check fan location from inside living area
before cutting shutter hole.
STEP 2. If the layout is satisfactory, cut and remove ceiling
material. (FIG. 2) Lift fan into the attic through the hole you

have just cut. Be careful not to damage the edges of the ceil-
ing when lifting the fan into the attic. IMPORTANT: THIS FAN
IS DESIGNED FOR HORIZONTAL INSTALLATION ONLY
FOR VERTICAL AIR FLOW. DO NOT MOUNT IT AT ANY
OTHER ANGLE.
STEP 3. Cut two 1" x 2” wood strips to span three joists.
Locate the 1” x 2” strips as shown in Fig. 3 and nail them to
each joist. Fasten the fan to the strips as illustrated using
the #12 lag screws, washers and rubber isolation mounts.

OPERATING YOUR FAN
IMPORTANT: DO NOT OPERATE THE FAN WITHOUT FIRST
OPENING A WINDOW OR DOOR TO PROVIDE INLET AIR FLOW. IF
FAN IS LOCATED IN HALL, YOU MUST OPEN DOORS TO HALL TO
ALLOW AIR FLOW INTO THE FAN.
The air movement in rooms can be increased by closing off parts of
the house. Each room must be treated as a separate ventilating case.
Always open the window farthest from the point that the air will leave the
room.
For best cooling results from your WHOLE HOUSE FAN open only the
windows in the room being use.
IMPORTANT: Fan should always be started on HIGH SPEED to
prevent possible motor failure.

REPAIR AND REPLACEMENT PARTS
STEP 4. - TURN OFF POWER AT FUSE BOX OR CIRCUIT
BREAKER. The fan requires a 120 volt A.C. power source with
at least 5 amp capacity. All electrical work must be in accordance
with local building codes using approved material. Follow wiring
diagram as shown below in FIG. 5 to finish electrical installa-
tion. Before restoring power, be certain the fan blades are clear
as the pull chain switch may be in the “on” position. If you are
using a separately purchased wall mounted control, follow
the instructions furnished with that control.
STEP 5. Cut out the plenum at premarked openings to fit your
ceiling joists. Attach the plenum to the deck using the #10 screws
and fender washers provided . Staple or tack the plenum to the
ceiling joist. Improper installation of the plenum can result in poor
fan performance or possible motor failure. Re-install insulation to
the edge of the plenum. Cover any opening with duct tape. The
plenum must be tightly sealed to the fan, joists and ceiling so the
fan draws air from the living area only. (FIG. 6)
STEP 6. Install flush mounted ceiling shutter into the ceiling
opening using the #101⁄4" screws included in the shutter carton.
Caution should be taken not to effect the free operating action of
the shutter. Drop the pull chain through the hole provided in the
shutter and trim it to desired length. Your installation is now com-
plete. (FIG. 7)

The following diagram is provided so you may deter-
mine the existing ventilation in your attic. It is necessary
that you provide adequate ventilation to meet the mini-
mum exhaust requirements for the fan you have select-
ed. Should you calculations show your exhaust area is
inadequate, additional ventilation must be provided.
Failure to meet minimum exhaust requirements will
result in a reduction of fan efficiency and motor failure.
