Product Usage Instructions
Installation Guide
Please read this installation guide carefully before proceeding with the
installation of the solar roof exhaust fan. Ensure the work area is dry and do
not install during or after rain.
Metal Roof Installation
Step 1 – Assessment
Study the figure to determine the number of fans required for your space.
Position the fan to receive optimal sun exposure, considering shade during
warmer months.
Step 2 – Flashing Installation
Remove ridge capping screws and slide the flashing under them.
Position the flashing to avoid covering roofing screws. Mark and cut an
opening on the roof based on the marked circle.
Step 3 – Roof Cutting
Cut an opening in the roof as marked, ensuring not to damage any underlying
battens/rafters.
Step 4 – Flashing Placement
Avoid applying silicone to the valleys at the bottom of the flashing.
Step 5 – Securing the Roof
Use tech or roof screws with rubber seals to secure the flashing in place.
Ensure a minimum of 8 screws are used.
Step 6 – Fan Placement
Position the main body of the fan over the flashing and adjust its direction
as needed for optimal solar panel exposure.
Step 7 – Fan Fixation
Screw the fan into place using small tech screws through the pre-drilled holes
in the fan body and into the flashing.

Installation Guide
Please read this installation guide carefully to install the solar roof exhaust fan. Depending on the roof type, you may follow installation steps for the best result. Please make sure work area is dry before installing. Do not install during or after rain.
METAL ROOF INSTALLATION
STEP 1
Study the figure to assess how many OmniPV fans you need and where to install them for your home or business. To work out where to position the fan, you need to take into consideration any afternoon shade on the roof during the warmer months. A well-positioned fan should allow the solar panel to receive sun from the south (north for southern hemisphere) and west during the warmer months.
Note: Shade will affect the fan performance. Number of fans needed may vary depending on the situations.
STEP 2
Remove 2 ridge capping screws and slide the top edge of the flashing up
under it as shown in the figure. It is important to position the flashing so
that it does not cover any roofing screws. The roofing screws running from the
top to the bottom of the roof are where the rafters are located.
Once positioned, mark a circle on the inside edge of the flashing.
STEP 3
Following the circle marked on the roof cut an opening in the roof as
shown, using a metal blade saw or tin snips. If there is any foil under the
metal sheets, cut a cross in the foil and fold back the corners.
Note: Take care not to cut into any battens/rafters under the roof sheet when cutting.
STEP 4
Slide the flashing back up under the roof capping and refit the 2 ridge
capping screws through the flashing and bend the edges of the flashing down on
the left and right sides of the flashing to create a tight fit with the roof.
Use tin snips to cut notches in the flashing’s bottom to suit the corrugations
of the roof and bend the notches down. Apply a silicone bonder to the
underside and the outside of the edges. After this, apply a silicone bonder to
the underside and outside of the bottom section of the flashing.
Note: Don’t apply silicone to the valleys at the bottom of the flashing.
STEP 5
As shown in the figure here, use a minimum of 8 and a maximum of 12 tech or
roof screws with rubber seals along the left, right, and bottom of the
flashing to secure the roof.
Note: Tech screws and roofing screws are not included.
STEP 6
Place the main body of the fan over the flashing as shown below. Turn the
main body of the fan left or right to suit the direction required for the
solar panel.
Tip: Position the solar panel between south (north for southern hemisphere) and west to best suit the sun in warmer months.
STEP 7
Using a powered screwdriver, screw at least 4 small tech screws through the pre-drilled holes in the fan main body through into the flashing as shown below.
Tip: You may not get the top tech screw in place the angle of the roof may prevent this, in this case, you can simply screw the tech screw into another section where the main body is over the flashing.
STEP 8
You can now adjust the angle of the solar panel to receive maximum sun
especially during the midday of the warmer months as shown in the figure. As
the pitch of many roofs is already at a good angle for the summer sun, you may
just be able to leave the panel in the down position as it is supplied from
the factory, without doing anything.
To adjust the angle of the solar panels up, just adjust the 2 arms to the
correct angle and tighten the screws.
Note:
An installation option is to fit the fan under the eave vents to the side of
the house that is cool in the afternoon. This will allow the cooler outside
air to be drawn into the roof space. These are especially required when the
roof has foil under the tiles, but regardless eave vents will improve airflow.
TILE ROOF INSTALLATION
STEP 1
Study the figure to assess how many OmniPV fans you need and where to
install them for your home or business. To work out where to position the fan,
you need to take into consideration any afternoon shade on the roof during the
warmer months. A well-positioned fan should allow the solar panel to receive
sun from the south (north for southern hemisphere) and west during the warmer
months.
Note: Shade will affect the fan performance. Number of fans needed may vary depending on the situations.
STEP 2
Remove the third tile counting down from the ridge capping (top of the
roof) as shown in the figure. Remove one complete tile from the roof. You may
also push the tile directly above the removed tile slightly up to make the
opening larger if necessary.
Ensure you discard this removed tile. Do not leave it on the roof.
STEP 3
Lift the tiles above the tile opening enough and slide the flashing into
place as shown here, and then push the tiles back down. This will mold the
flashing to the tiles.
STEP 4
Fit a minimum of one rafter/batten strap (2 are supplied) as shown. The
strap folds over the circular ridge on the flashing and it can either be
screwed or nailed through the rafter/batten strap into the rafter or batten.
Note: Rafters run from the top of the roof down to the facial and battens run across the roof directly under the tiles.
STEP 5
Once the fitting of the flashing is complete, run a bead of clear silicone
along the top of the flashing that joins with the upper tiles.
STEP 6
Place the main body of the fan over the flash-ing as shown below. Turn the main body of the fan left or right to suit the direction required for the solar panel.
Tip: Position the solar panel between south (north for southern hemisphere) and west best suit the sun in warmer months.
STEP 7
As shown in the figure, using a powered screw-driver, screw at least 4
small tech screws through the pre-drilled holes in the fan main body through
into the flashing.
Tip: You may not get the top tech screw in place the angle of the roof may prevent this. In this case, you can simply screw the tech screw into another section where the main body is over the flashing.
STEP 8
You can now adjust the angle of the solar panel to receive maximum sun
especially during the midday of the warmer months as shown in the figure. As
the pitch of many roofs is already at a good angle for the summer sun, you may
just be able to leave the panel in the down position as it is supplied from
the factory, without doing anything.
To adjust the angle of the solar panels up, just adjust the 2 arms to the correct angle and tighten the screws.
STEP 9
Now that the primary installation is complete, you can mold the flexible flashing to suit your tiles and bend the bottom section of the flashing down to allow water to run off onto the tiles below. Then run a bead of silicone along the left and right sides of the flashing and your job is complete.
Note:
An installation option is to fit the fan under the eave vents to the side of
the house that is cool in the afternoon. This will allow the cooler outside
air to be drawn into the roof space. These are especially
required when the roof has foil under the tiles, but regardless eave vents
will improve airflow.
