Press this switch to open or close the dome.
The dome can be stopped in any position. To
conserve power, the fan will stop while the
dome motor is running. Automatic overload
protection will stop the dome in case of an
obstruction, such as a tree branch.
Use this knob to manually open or close the
dome. The dome can be stopped in any
position. If equipped with a motorized
dome, pull the hand crank down to
disengage the motor before turning by hand.
Push the hand crank up when finished to reengage the dome motor. Dome must be
fully closed when the RV is in motion.
Press this switch to change fan direction to
blow air out of the RV (Exhaust) or to bring
outside air into the RV (Intake). Fan works best

product life, fan blade should be stopped before
changing directions.
To remove the screen
for cleaning of the fan
blade and housing,
unsnap the 4 clips. To
reattach the screen,
snap the 4 clips into
place.

fan with the screen
