INSTALLATION GUIDE
PROTECTIVE GEAR
Before you begin, make sure to protect yourself
from potential injuries by wearing protective gear
including: safety goggles to prevent any drywall
dust or insulation from getting in your eyes,
gloves to avoid direct contact with insulation, and
a dust mask to avoid inhaling dust as a result of
cutting into the drywall and insulation.
FAN POSITIONING
A whole house fan is installed in the ceiling of a
home and moves air from the living space into
the attic. It forces hot air out of the attic and pulls
cooler air from the outside of the house into the
living space, which is ideal for people who come
home to a hot house when it is cooler outside.

MOUNTING
STEP 1
Before installing the whole house fan, find a
location in the hallway or staircase central to
the home. In the attic, mark the corners using
grille plate in between the ceiling joists. Then
press each corner with a screwdriver or drill
until it reaches the other side.
STEP 2
Line up the grille plate with the reference
holes made in the attic. Mark around the
grille plate to create a cutout guide.

MOUNTING
STEP 4
Remove the white grille plate off the damper
box. Place the damper box inside the attic vent
side down onto the cut hole, as shown in the
image.
The black damper screws may also used to
secure the damper box to the drywall. Drill
through the metal to mount the damper box.
STEP 3
Check your location and measurements
before cutting into the drywall. Use a drywall
saw or jigsaw to cut out the marked location.

MOUNTING
STEP 5
Loosely attach the duct tube to the fan to
determine the mounting area. Position the
fan in an area where you can mount the fan.
Remove the duct tube after positioning the fan.
As an option you may use the included rope
clips to hang your fan from a support beam
instead of mounting it.
STEP 6
Once a location has been set for the fan,
remove the metal rings so you can pull out the
center motor. Use the mounting flanges to help
you position the fan to your desired mounting
location. Use a pen or pencil to mark the four
mounting holes.

Mounting Flanges

STEP 7
Double check to make sure the location is
structurally sound and free from obstruction.
Use a power drill to drill the four mounting
holes.
MOUNTING
STEP 8
If you are mounting onto anything other than a
wood support or stud, insert the included four
wall anchors into the drilled mounting holes.
You may need to use a hammer to secure them
through the holes.

13
MOUNTING
STEP 10
Place the metal rings back onto the flanges.
Position the wind circle back into the flange.
Do not tighten the screws yet.
STEP 9
Position the mounting flanges and align the
mounting holes with the wall anchors. Use a
screw driver or drill to secure the four wood
screws through the mounting frame and into
the wall anchors or stud. Make sure the arrow
is pointing in your desired direction.

14
STEP 11
Secure the motor box back onto the mounting
flanges. Make sure the arrow on the motor box
points in the same direction as the arrow on the
exhaust flange.
MOUNTING
STEP 12
Connect the duct tube to the intake flange.
Secure the duct clamp over the duct tube and
tighten it with a flathead screw driver.

15
MOUNTING
STEP 14
To tighten the rope, pull the loose end until the
duct tube feels secured. Avoid sharply bending
the tube so airflow won't be restricted.
STEP 13
Use the included rope clips to support the duct
tube. Clip them onto a nearby beam. If there
is no beam or an area to hang the rope clips,
secure a nail nearby to hook the rope onto.

16
MOUNTING
STEP 16
Secure the vent using the included four white
screws into the drywall.
*Note: The screws will only secure the vent to
the ceiling drywall. The damper will rest on the
drywall and vent.
STEP 15
Place the vent onto the dampener through
the opening from below the ceiling.

STEP 17
Position the controller close to the fan and
inside the attic so that the power cord reaches
the controller.
MOUNTING
STEP 18
To mount the controller, use the appropriate
screws included for your mounting location.

18
POWERING AND SETUP
STEP 2
Secure the sensor probe head, preferably
near the hottest area of the attic. Screw in the
square tabs once you find a suitable location.
Then use the included zip ties to secure the
probe.
STEP 1
Locate the connector plug of the
thermal probe and plug it into the
bottom of the thermal controller.

19
STEP 3
Connect the molex end from the fan into the
bottom of the Universal Controller. Be sure to
plug it into the left molex 4 pin connector that
has the power and fan icon. This plug is meant
to power the controller.
POWERING AND SETUP
STEP 4
Plug the fans power cord into an AC power
outlet to power both the fan and the controller.

CLEANING
STEP 2
Clean the dust and dirt off the stator blades
on the opposite side. Remember to clean the
area inside the output and exhaust flanges.
Lastly secure the motor box onto the mounting
flanges. Secure the motor box with the metal
rings.
STEP 1
Remove the motor box from the mounting
flange to remove any dust or build up. Use a
damp cloth to clean the dust and dirt off the
impeller and fan blades.
