d in package to 
comply with severe weather building codes. Includes Solar Controller™\
 for after dark operation. 
BEFORE YOU INSTALL - Install only one type of exhaust vent and remove or plug any existing ve\
nts (gable vents, roof louvers, 
ridge vents and turbines). Install adequate intake ventilation for a Ba\
lanced System (50% Exhaust & 50% Intake) in accordance with 
state and local code requirements. Intake vents must be installed low at\
 the roof’s edge or in the soffit/undereave. Products such as Air 
Vent’s Continuous Soffit Vent, Vented Drip Edge, Undereave Vents and The Edge™ Vent provide the necessary intake ventilation for 
optimum performance.

SOL AR POWERED
Mounting the Fan
south or southwest
mid-d ay summer sunStep 1 – Positioning of the Solar Fan
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. 1) 
fig. 1
Step 2 – 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 a\
nd roof shingle so it will be easily 
located from on top of the roof.
Some models include in the box a template for cutting out the hole. It i\
s printed on the cardboard protecting 
the base of the fan. Punch out the template. From on top of the roof, lo\
cate the screw and place the card-
board 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. 2) 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 3 – Cutting the Hole
Using a power drill equipped with a ½ - 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. 3) 
Do not cut through any roofing rafters or framing members! Only cut an\
d remove the roof sheeting 
and shingles. Prior to cutting the hole, make sure you do not have any w\
ires or waterlines in the area 
that you are cutting. Before completely cutting out the circle, secure t\
he removed material so it does 
not fall into the attic space. fig. 3

							Step 4 – 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. 4)  You should use a pry bar or reciprocating saw to 
loosen or cut any nails and/or staples.
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 lar\
ge washers to install the felt paper. In 
this case lift up on the flashing as you are sliding it under the shin\
gles.fig. 4
 Step 5 – Installing the Solar Fan
Position the Solar Fan so that it is directly below the hole (fig. 5a) using the “Up” label 
as a guide for orientation. Begin sliding the flashing of the Solar Fa\
n underneath the 
shingles and on top of the felt paper at the mid-point of the hole (fig. 5b).  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. 5c). To comply with 
Florida Building Codes and TDI, remove shingles from all around the fl\
ashing and 
secure all 8 holes.

Step 6 – Securing the Solar Fan
Using the provided steel screws, secure the solar fan to the roof.  The \
solar fan should be secured across the bot-
tom and on the sides of the flashing by driving screws through the vis\
ible 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. 6). Use roofing nails as needed to secure any shingles that remain loo\
se. Apply 
waterproof roofing sealant to the backside of any loose shingles or na\
il heads that have been added.

Mounting the Solar Panel
Step 7A – Mounting onto the Solar Attic Fan
Loosen and remove screw A on the solar panel (both sides) to allow the\
 panel to swing away 
from the base. Set the screws aside. (fig. 7) Pull the wire from the top of the fan housing through 
the hole in the center of the panel base and lay the panel down so the b\
olts come through the 
adjusting slots in the panel base. (fig. 8 and fig. 9) Tighten the bolts on the panel base at the 
desired angle for optimal panel direction.(fig. 10)

Attach the cable coming from 
the junction box to the cable 
coming from the top of the 
fan with the quick connector. 
(fig. 11)
Step 7B – Mounting Remotely (AV9930TRS Model)
Use the Quick Connector cable coming through the top of the solar attic \
fan dome (fig. 12) and conect the 
wire extension directly to this cable. Use the other end of the extensio\
n wire to attach to the solar panel. 
Use roofing staples to secure the extension cable to the roof.
Choose a location for the solar panel that will receive optimal afternoon sun, preferably southwest facing, 
and free of shade from trees or other buildings.
Loosen and remove screw A on the solar panel (both sides) to allow the\
 panel to swing away from the 
base. Set the screws aside. (fig. 13)
Mount the solar panel base using four 3” galvanized screws, (fig. 14) making sure to seal the screw holes 
with a waterproof roofing sealant as shown (fig. 15). 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 
waterproof roofing sealant to completely dry before contacting with the panel.

							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 ef-
ficiency.  If necessary, simply hose off the solar panel between rain showers.
Adjusting the Fan
Step 8 – Adjustments
The fan’s solar panel should be adjusted to maximize exposure to the sun’s path during the day. The opti-
mal 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. 16)

The Solar Controller™ has a built in thermostat and humidistat that will measure the attic tem-
perature and humidity and allow the fan to have extended run time in the\
 evenings or when no 
solar is available. Refer to Solar Controller for installation instructions.
