Mounting the Fan
Sizing Requirements
See sizing chart on the box or www.ussunlight.com to assure that you select the correct number of
fans for your situation. Some attics have walled off or chambered areas that will require additional
fans to properly vent the space.
If you have any questions or concerns please feel free to call our customer service specialists at 877-50-USSUN.
Determine your mounting application
One of the great features about the All Purpose Ventilator is the many mounting options.
Gable Vent Static or Turbine Vent Crawlspace Vent
If you have a tile roof and do not want
to cut into the tiles, use the gable vent
for mounting the fan.
Rather than removing the static or
turbine vent, simply use the same
opening.
If your crawlspace has too much moisture,
increase the airflow and reduce moisture
by installing near a vent opening.
Important Tip:
To maximize the solar fan’s effectiveness you should remove or block any rooftop
static vents or ridge vents. Make sure you have proper intake ventilation at the
eave or fascia. Use a ratio of 1 sq. ft. of intake ventilation for every 600 sq. ft. of attic
space. To maximize airflow to the attic close off any unused static vents. Use tar
paper and staples as shown.
Before you begin:
Loosen (but do not remove) the 8 nuts (fig1) on the 4 mounting brackets
(fig 2) so they can slide freely. And remember: Always note the
orientation of the fan’s air flow relative to the vent opening.

Gable Vent Installation
For installation in a gable vent you typically have 2 options:
Step 1.
Position the fan over the louvers and slide the mounting
brackets into position against the vent frame. (fig. 3)
Step 2.
Mark the position of the holes in the brackets and pre-drill
if necessary. (fig. 4) fig. 3 fig. 4
16”
on center
Option 1 - vent is located between standard 16” on center framing members
Important tip for both gable fan installations:
To maximize efficiency of the fan, seal off the gable vent area around the fan to avoid recirculating outside air
around the fan and back outside.
seal off with tar
paper or duct
tape
Step 3.
Use included screws “G” to fasten the brackets to the vent frame. There are 8 positions two on
each bracket. (fig. 5)
Step 4.
Once brackets have been fastened, slide the fan assembly into position, pressing it firmly
against the vent louvers and tighten the 8 nuts. (fig. 6)
fig. 5 fig. 6

Step 1.
Measure the distance between
the 2 framing members that the
braces will attach to. (fig. 7) fig. 7 fig. 8

between
14.25” and 15”
Option 2 - vent area requires additional mounting braces to support the fan
Step 4.
Then mount the fan as
described in option 1.
(fig. 10)
Static or Turbine Vent Installation
The All Purpose Ventilator can be used to push hot air out of your attic through existing roof vent.
Important Tip: Seal off other static vents to avoid turning them
into intake vents once the powered fan is installed and running.

Step 4.
Position the fan assembly between the
two braces and slide the fan assembly
towards the vent opening. (fig. 15)
Step 5.
Fasten the brackets to the two braces
with included screws “G” (fig. 15) and
tighten the 8 nuts. (fig. 16)
Crawl Space Vent Installation
Keeping air moving in your crawl space can help to remove moisture and inhibit mold and mildew growth. The All Purpose
Ventilator can be mounted as described above, or a box frame can be built to hold the fan in position. It is recommended that
you evaluate your crawlspace to determine the best method.
Step 2.
Cut two 2x4 braces to the
required length. (fig. 8)
Step 3.
Locate the two braces between 14.25” and 15” apart
and centered over the vent opening then fasten to the
framing members with 3” screws (not supplied). (fig. 9)
Note:When the rafter is greater than
5” wide locate the braces between
the rafters to insure fan can be posi-
tioned against the vent.
Step 3.
Locate the two braces between14.25”
and 15” apart and centered over the
vent opening then fasten to the rafters
with 3” galvanized deck screws (not
supplied). (fig. 14)
Step 2.
Cut two 2x4 braces to the required length.
Step 1.
Determine the location of the vent to
be used and measure the distance
between the two rafters. (fig. 13)
fig. 17
To build the box frame
Step 1.
Depending on the distance your
floor joist are seperated, you
will need to cut 4 braces: two at
14.5” for the side braces, one at
17.5” for the bottom brace and
one between 17.5” and 25.5”
for the top brace (fig. 17). Most floor joists are either 16” on
center or 24” on center. Measure the distance before cut-
ting the top brace to be sure of the distance required.

inner dimension
should be 14.5”
14.5”
top brace should be 17.5” to 25.5”
depending how wide the floor
joist span is.
Step 2.
Fasten the 4 boards together with 3” screws to make a
square box with inner dimensions 14.5” x 14.5”. (fig. 18 & 19) fig. 21a

Step 3.
Mount the frame in front of the vent opening by attaching it to the floor joists with 3” gal-
vanized screws. If the frame assembly and fan mount lower than the bottom of the vent
opening, (fig. 20) mount the frame about 8” to 10” away from the vent to prevent direct
contact with the foundation when the fan is mounted. (fig. 21a) Secure the frame to the
bottom of the floor joists with at least 2 screws on each side making sure it is centered
evenly on both. (fig. 21b)
Step 4.
Mount the fan inside the frame by attaching the brackets
with included screws “G”. Center the fan in the frame
making sure that there is at least 4” of clearance
between the fan housing and the crawlspace vent
opening. (fig. 22)

Mounting the Solar Panel
Determine the distance between the vent and
the area you will be mounting the solar panel
The fan’s solar panel should be adjusted to maximize exposure to the sun’s path during the day. The optimal adjust-
ment is to have the panel 90 degrees to the midday path of the sun (south or southwest facing slopes are best).
You can re-adjust the panel during winter or summer seasons if desired.
The Solar panel unit comes with 30 ft. of wire. It is a good idea to measure the distance from the vent opening and where
you’ll be installing the panel to make sure you have enough wire to cover the span. (fig. 23)
fig. 23
Surface mounting on composition roofs:
fig. 24
fig. 25
screw A
Step 1.
Loosen and remove screw A (both sides)
to allow the panel to swing away from the
base. Set the screws aside. (fig. 24)
Step 2.
Before mounting, make sure to pull the
wire back through the hole in the center
of the base so the base can lay flat on the
roof surface when installed. (fig. 25)
Maintenance Tip: The solar panel is most effective when clean and free of dust, leaves, and debris. Normally,
rainwater will cleanse the solar panel and keep it operating at peak efficiency. If necessary, simply hose off the solar
panel between rain showers.
Step 3.
Mount the base using four 3” galva-
nized screws making sure to seal the
screw holes with a roof tile adhesive
as shown. Tilt the panel away from the
base while installing the screws. If the
panel is to remain flat against the base
when installed it is recommended
that you allow the roof tile adhesive to
completely dry before contacting with
the panel. (fig. 26 & 27)
fig. 26
fig. 27
fig. 28 fig. 29
mount on at
least 2 tiles
Surface mounting for S-Tile, Flat Tile or Metal roofs
Step 1.
Determine the location of the contact points by positioning the panel in the desired area.
For S-Tile roofs, find a position with as much surface area coming in contact with the
bottom of the panel as possible. The panel must be mounted on at least 2 rows of tile as
shown. (fig. 28 & 29)
Step 2.
Apply enough roof tile adhesive to the underside of the base to firmly secure the panel
to the surface. Both surfaces should be dry and free of any dirt or solvents. (fig. 30)
Step 3.
The panel can be tilted into two positions with the adjustment arm, chose the best angle
and reinstall the adjusting screws (screw A). (fig. 31) fig. 30 fig. 31

Wall mounting:
Brackets are included to mount the panel to a wall if preferred.
First, assemble the braces to the brackets as follows:
fig. 32
bolt D
Step 1.
Attach the brackets to the panel using the 4 bolts (D.) (fig. 32)

Step 2.
Depending on the material your wall is made of,
mount the assembly to the wall using appropriate
fasteners (see “Optional Hardware” on page 1 for
details). (fig. 33 and 34)
fig. 33 fig. 34
see Optional
Hardware on
page 1
Connecting the panel to the fan:
Step 2.
Typically the wire will route through an opening in the vent or an unused
louver. (fig. 36)
Step 3.
Connect the wires to the fan, matching the red wire to the red connector
and the black to the black connector on the motor. (fig. 37)
Step 4.
Include a drip curve if possible when securing to the wall to prevent
water running down the wire and into the attic or crawl space. (fig. 38)
Step 1.
Once the panel and fan are mounted, route the wire from the panel to
the fan, attaching the wire to the building appropriately. We suggest
using romex mounting clips or coaxial staple for either wood or masonry
available at your local hardware store or home builder supply. (fig. 35)
With the optional fascia bracket kit, the panel
can be mounted directly to a fascia board.
Fascia mounting kit
Additional Accessory Available
The Solar Controller™has a built in thermostat and humidistat that will measure the attic
temperature and humidity and allow the fan to have extend run time in the evenings or
when no solar is available. Visit www.ussunlight.com for additional information.
™
Thermal Switch - Optional Installation
The thermal switch will shut down the fan when the temperature drops below approximately 65˚F
and turn the fan back on when the attic temperature rises to approximately 80˚F. To install the
thermal switch, remove the BLACK lead from the fan motor and attach it to the thermal switch. Attach
the other lead from the thermal switch to the BLACK terminal on the motor. Secure the wires to the
motor bracket with tape or zip ties to prevent them from interfering with the fan blade. If you prefer
to have the fan running during cooler seasons to remove moisture from the attic, do not install the
thermal switch (fig. 39). As an upgrade from the mechanical thermal switch, utilize the Solar
Controller with an electronic thermostat and humidistate as well as additional features.
