SRS Labs GBL1250 FT Installation Instructions

USE THIS PAGE FOR - Mounting an SRS Gable Fan behind a louvered gable vent.
™
TheSunRise Solar-Powered Gable Fan is designed to mount behind existing louvers on the inside of the attic. If
no louver exists, onemust be installed. Louvered vent should be mounted in the center of the upper portion of the
gable wall as high as possible. There is some loss in fan output because louvers block some of the air flow. Metal
louvers havemore open area than wood louvers and usually allow more air flow.
When installing the SunRise Gable Fan behind louvers, you should seal off or box in any louver area not covered by
the ventilator housing to prevent air leakage and recirculation. Allow at least one square foot of air intake area for
every 300CFMof ventilator capacity. Air intake should come from the eaves (soffit), or a louver mounted on the
opposite gable end of attic.
CAUTION: When installing louvers, do not remove existing structural members without providing alternate support.
Example of typical louvered gable vent

Mounting Instructions:

1) Screw or nail Gable Fan Housing to framing directly behind gable louver as discussed above.
2) Remove solar panel from packing. Find a suitable location on the roof to mount solar panel – a Southern or
Western-facing roof slope will allow the solar panel to capture the most sunlight during the heat of the day.
The solar panel comes with a 15' extension cord, so be sure the solar panel is not more than 15' from the
Gable Fan Housing inside the attic.
3) If possible, feed the wire into the attic through an existing vent hole or ridge cap. Or, drill a 3/8" hole through
the roof and feed the wire down into the attic. Apply a generous amount of silicone or other sealant to the
area where the wire goes through roof.
4) If installing a SunRise 1250 Panel in ABS Frame, set the solar panel in place, and mount to roof using the
(8) exterior-grade screws provided. Apply sealant to screw heads and around perimeter of
mounting flange to prevent leaks. If installing a SunRise 1650 or SunRise 2000 please refer to the
METAL FRAME instructions on the back of this sheet.
5) From inside attic, connect wires to solar panel, matching red (or white) to red and black to black.
6) Gently plug wire connectors into tabs on side of motor, red to red and black to black.
7) Use included wire ties to secure loose wire to motor bracket arm.
NOTE: Wire connections must be correct before completing the installation. If positive (red or white) is
mistakenly plugged into the negative (black or blue) side it will not harm the motor, but the fan will not run.
