STEP 3
Prior to installing the MAXXFAN MINI
hood portion over the roof opening,
apply a continuous strip of BUTYL tape
or equivalent to the underside of the

flange in the area under the screw
location dimples.
CAUTION! When installing your
MAXXFAN MINI, only use a
caulking/sealant compatible with the
flange (plastic product) and the roof
surface. DO NOT use materials
containing solvents such as or similar to
Xylene, Toluene, Methyl Ethyl Ketone
(MEK), Acetate or Acetone as they can
damage the flange. Also, Polysulfide
(Thiokol) type sealants must be avoided.
If in doubt, please contact the
manufacturer of your RV.
STEP 4
Insert the MAXXFAN MINI hood into the
roof opening with the louvered section
facing the rear of the vehicle and
centering the hood in the opening. Using
the twenty-eight (28) screws provided,
attach the flange to the roof at each
dimple location along the flange. Screw
into the dimple to pierce the flange,
making sure not to overtighten the
screws to avoid cracking the flange.
STEP 5
After the MAXXFAN MINI hood has
been installed, remove the excess
BUTYL caulk that may have squeezed
out. Using a sealer such as Dicor self-
leveling lap sealant or similar caulking,
apply a daub over every exposed screw
head. In addition, apply a bead
(approximately 3/16” dia.) along the
outside edge of the flange all the way
around the vent.
THIS COMPLETES THE ROOF
TOP PORTION OF THE
INSTALLATION

before connecting 12 volt DC power to the
MAXXFAN MINI Plus or MINI Deluxe!
STEP 6

into the open hole in the side of the
metal bracket on the MAXXFAN Mini,
allowing 4 to 6 inches of wire inside the
bracket. Secure the wires to the bracket
with the supplied strain relief bushing.
Using the supplied wire nuts, connect
the Positive (+) 12VdC supply wire to
the MAXXFAN Mini marked “POS

notch in the back of the MAXXFAN MINI
Plus/Deluxe interior plate, place sleeve
over interior plate with supply wires
routed through hole formed between
interior plate and sleeve.

RJ45 cable can be routed through any
side of the Mini as needed.
STEP 8
Raise interior plate/sleeve to ceiling and
ensure that sleeve meshes with
MAXXFAN MINI roof top flange. Refer
to screw lengths in the table of STEP 2
and use the proper length screws
depending on your roof thickness to
secure the interior plate to the roof top
flange, taking care not to overtighten the
screws to avoid cracking or deforming
the interior plate.
