Installation Instructions
It is suggested that you prepare the opening prior to bringing the fan up on the roof.
Always secure the fan on the roof to avoid injury or having the fan slide off the roof and get damaged.
Step 1 - Ventilation
To maximize the solar fan's effectiveness you should remove or block any rooftop static vents or ridge
vents. If there is an existing turbine type vent, simply remove the old vent and use the same hole for
the new installation, or block completely. (fig. 1) 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.
Block or
fig. 1
Important Tip:
To properly close off any static vents, use tar paper and staples
as shown in (fig. 2 & 3).

Mounting the Fan
Step 2 - Sizing Requirements
See sizing chart on the product box or visit our website at 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 call our customer service specialists at: 1-877-50-USSUN
south or southwest Step 3 - Positioning of the Solar Fan
mid-day summer sun
The solar fan should be positioned to face south or southwest for optimum performance and should be
positioned on an area of the roof that is not shaded or otherwise blocked from the sun for extended periods
throughout the day. The solar fan should be installed 18 — 24 inches from the top of the roof peak and as
close to the mid-point of your house as possible. In the case that 2 or more fans are getting installed you
should separate the fans by at least 15 feet to optimize ventilation. (fig. 4)
fig. 4 Step 4 - Marking the Hole
From inside the attic, measure down from the roof peak approximately 18 to 24 inches and center this
spot between two rafters. Drill a screw through this mark into the plywood and roof shingle so it will be 24
easily located from on top of the roof.
roof peak
Some models include in the box a template for cutting out the hole. It is printed on the cardboard protect-
ing the base of the fan. Punch out the template. From on top of the roof, locate the screw and place the
cardboard template over the top of the screw aligning it in the center hole of the template. Using a pen
or marker, trace a circle around the outer edge of the template, resulting in a circle with a 14” diameter.
(fig. 5) If your product box does not include the template, simply use a 7” string, one end attached to the
previously drilled screw and the other tied to a pen or marker to create a 14” diameter circle.
Step 5 - Cutting the Hole fig. 5
Using a power drill equipped with a ¥2 - 1” drill bit, drill a pilot hole anywhere along the
inside of the circle. Insert the saw blade into the pilot hole and follow the circle pattern to cut the hole
into the roof. (fig. 6)
| shingles. Prior to cutting the hole, make sure you do not have any wires or waterlines in the area that
you are cutting. Before completely cutting out the circle, secure the removed material so it does not fall
into the attic space.
Step 6 - Lifting the Shingles
The nails located 5” above and to the side of the hole will need to be removed for the solar fan flashing
to slip between the felt paper and the shingles — (fig. 7) You should use a pry bar or reciprocating saw
to loosen or cut any nails and/or staples.
Do not cut through any roofing rafters or framing members! Only cut and remove the roof sheeting and

fig. 6 WARNING
Do not attempt to force the unit into place. If it does not slide easily into place, a nail is most likely
obstructing the flashing. In some cases the builder may have used large washers to install the felt fig. 7

Step 7 - Installing the Solar Fan
Position the Solar Fan so that it is directly below the hole (fig. 8a) using the “Up” label
as a guide for orientation. Begin sliding the flashing of the Solar Fan underneath the
shingles and on top of the felt paper at the mid-point of the hole (fig. 8b). Continue sliding
the solar fan upward (making sure that the top of flashing is facing toward the top of the
roof) until it is positioned directly over the attic hole (fig. 8c). To comply with Florida Build-
ing Codes and TDI, remove shingles from all around the flashing and secure all 8 holes.
Step 8 - Securing the Solar Fan fig. 9
Using the provided steel screws, secure the solar fan to the roof. The solar fan should be secured across the
bottom and on the sides of the flashing by driving screws through the visible pre-drilled holes at the bottom edge
of the flashing. To comply with Florida building codes and TDI, secure in all eight holes. Apply waterproof roofing
sealant to the screw heads (fig. 9). Use roofing nails as needed to secure any shingles that remain loose. Apply
waterproof roofing sealant to the backside of any loose shingles or nail heads that have been added.
Adjusting the Fan _
Step 9 - Adjustments at midday.
The fan’s solar panel should be adjusted to maximize exposure to the sun’s path during the day. The
optimal adjustment is to have the panel 90 degrees to the midday path of the sun. You can re-adjust
the panel during winter or summer seasons if desired. (fig. 10)

To adjust the tilt of the panel
Remove screw “A” on both sides of the panel assembly and set aside. (fig. 11) Lift the panel and swing panel braces up to desired
position and re-attach screw “A” in the appropriate holes. There are 3 positions to choose from. (fig. 12)
To adjust the rotation of the panel
Loosen nut “B” (there are four) (fig. 13), then rotate the panel base to the desired position (fig. 14) and re-tighten
the nuts. The panel base can be rotated up to 360 degrees by completely removing nuts “B”, lifting the assembly
off the bolts and re-positioning accordingly. Re-attach the nuts and tighten when completed.
Some models require rotating the shroud to change the direction of the panel 3
To rotate the shroud, remove the self-tapping screws (screw “B”) (fig. 15) from each of the four brackets and set "screw B £7
them to the side (additional screws have been provided for your convenience). Rotate the shroud to the proper
position and use the self-tapping screws to re-attach the brackets to the shroud (there is no need to seal the
previous holes).
Prior to rotating the shroud, make sure that the wire that connects the motor to the solar panel has enough slack
to turn the shroud. (fig. 16) If not, cut the zip ties that hold the wire prior to rotating and re-attach the wire to the
rodent screen using the additional zip ties provided.

— ren Thermal Switch - Optional Installation
pa If your solar fan unit did not come with the thermal switch, it is available for purchase as an accessory
at www.ussunlight.com. The thermal switch will shut down the fan when the temperature drops below
leave as is) D 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. 15). As an upgrade from the mechanical thermal switch, utilize the Solar Controller with an elec-
an fig. 15 tronic thermostat and humidistate as well as additional features.
