Maxxair MaxxFan User manual

Step 1
Remove the old existing roof vent. Remove all old roof sealant for a minimum of 2” entirely around the
roof opening.
Place the MaxxFan Roof Receiving Flange (ref. photo #3) into the roof opening and trace a pencil line
around it to verify the clean seal area that will be required. Note that the Roof Receiving Flange must be
centered in the roof opening with the metal clips facing the sides of the vehicle (not facing the front or rear
of the vehicle).

NOTE: Refer to supplied attachments for further instructions regarding the model you have
purchased.
The MaxxFan installs into a standard RV roof opening of 14 by 14 inches.
To determine if your roof opening is correctly sized, simply remove the interior ceiling garnish trim
ring of your existing roof vent and measure the ceiling opening or verify the opening is large enough
by sliding the MaxxFan interior Garnish trim ring into the opening.
Due to the exhaust/intake louvers that face the rear of the vehicle, the MaxxFan requires a roof
area clear of obstructions such as air conditioners, storage boxes, etc. for at least 8 inches to the
rear of the existing standard roof vent flange outer rear edge.
The MaxxFan is designed for a minimum roof thickness of 1 1/8 inches to a maximum of 6 1/2
inches. If your roof thickness is less than 1 1/8 inches, build additional thickness at the ceiling
opening using wood or other suitable material.
The MaxxFan requires a minimum 12 Volt DC, 5 amp service. Confirm that the circuit you intend to
use will accommodate the additional load. Use the proper gauge stranded wire for electrical
connections.

Step 2
Apply factory recommended roof sealant to
the area traced with the pencil. Apply roof sealant
carefully so that no gaps are present that may
allow water to enter.
Step 3
Fasten the Roof Receiving Flange to the roof
with the screws provided.
Apply additional roof sealant over the screw
heads and around the edge of the roof flange.
Caution: Disconnect main vehicle
power before connecting 12 volt DC
power to the MaxxFan!
Step 4
Using the insulated electrical connectors
provided, connect the vehicle 12 volt power to the
two MaxxFan power wires located on the driver
side of the MaxxFan.
Note: The MaxxFan black wire identified with a
tag showing (+) must be connected to the
vehicle 12 volt (+) positive supply.
Disconnect main vehicle power
again before proceeding!
Step 5
Confirm that the 4 metal mounting clips are
firmly in place on the Roof Receiving Flange.
With the MaxxFan open and the exhaust/intake
louvers facing the rear of the vehicle, lower the
MaxxFan onto the Roof Receiving Flange.
Make sure the power wires slide to the vehicle
interior and do not become entangled on the
Roof Receiving Flange upward edge.
Step 6
Verify the MaxxFan is fully seated down on the
Roof Receiving Flange and fasten the MaxxFan
to the Roof Receiving Flange using the four 3/4
inch long by #10 Stainless Steel screws pro-
vided. (Caution: Only use screws provided/
specified for this installation)
This completes the roof top portion of
the installation.
NOTE: After making the 12 volt DC power
connections you may re-apply vehicle power
and temporarily operate the MaxxFan to
verify proper wire connections. Please note
that the MaxxFan motor only operates when
the MaxxFan is fully opened. Use the Vent
Open Knob, pull down and outward to
unlock and fully raise the MaxxFan vent lid.
(See attached operating instructions.)
Verify that the fan operates in exhaust
when the exhaust switch is selected, if not,
reverse the 12 volt DC power leads to the
MaxxFan and verify correct operation.

Step 7
The interior Garnish Trim Ring must be
trimmed to fit your particular RV roof thickness.
To accomplish this, measure the distance from
the vehicle ceiling surface to each corner of the
MaxxFan Control Plate.
Most RV roofs have some slope, so measuring
each corner is necessary. The Garnish ring
should be cut 1/4 to 1/2 inch longer than the
dimensions measured at each corner.
7
7A - After adding 1/2 inch more, a line is drawn
on the outside of the Garnish Ring at 4 inches.
7B - Connect all four corners with a line at the
required dimension and trim accordingly.
Step 8
Complete the installation by placing any excess
wiring to the inside of the roof opening and sliding
the Garnish Ring into position. Fasten in place
using the four painted flat head screws provided.
For additional information about your
MaxxFan, please read the enclosed
“Information and Operating Guide”.
