WARNING: ELECTRIC SHOCK HAZARD .
Turn the power off before performing any electrical
installation or maintenance activities. Failure to obey
this warning could result in death or serious injury.
NOTICE: Always use sealant on (clean) parts and
surfaces where wiring or fasteners enter the RV's walls,
roof, or floor. Otherwise water damage could occur.
If using sealant for rubber roofs, use an EPDM-

without a solid substrate to support a rooftop screw
installation. See "Clamp-Fan Mount" on page 11.

place a gasket on the opening and apply the sealant
around the outer edge of the gasket.

No sealant should be placed on the top or
bottom of the gasket.
2. Position the fan over the opening, making sure the
sealant and/or gasket is "sandwiched" between the
bottom of the mounting flange and the roof opening.
– When positioning the fan on the roof, the lid
hinge should be closest to and aligned with the
front of the RV.
– If positioning the fan on the side of the RV
(vertically), the lid hinge should be closest to and
parallel with the roof line.
3. Use the screws to secure the fan to the RV.
