1. Choose a roof vent on your RV that will serve your ventilation needs and is strategically located for obtaining 12 volt DC power. Be certain the 12 volt RV circuit selected is capable of supporting the 4 additional amps generated by the Turbo/Maxx.
2. Open your roof vent 3" or 4". Mark a 6"
B
line on the roof surface with a straight edge
from both vertical corners (A). Repeat this
procedure for the front of the vent as show
(A). This will aid in centering the
Turbo/Maxx over the vent.
3. Place your Turbo/Maxx over the vent.
Use the pencil lines to center the
Turbo/Maxx by evenly locating the mounting
C
feet between the pencil lines (B).
4. Mark the location of the holes in the
mounting feet onto the surface of the roof
(C). Remove the Turbo/Maxx and position
the mounting brackets at each corner of the
roof vent as shown. The mounting hole pen-
cil marks should show through the slots in the mounting brackets (C1).
C1
5. With each bracket positioned as above, mark the two small holes of each bracket onto the side wall of the vent (C2). Repeat this for all four brackets, then remove the brackets to drill these marked holes using a 5/32" dia. drill bit (C3).
Note: If your roof vent frame is plastic,
C2
and/or a more secure mounting installa-
tion is desired, you may perform the fol-
lowing:
Additionally fasten the Turbo/Maxx bracket down to your roof surface using a #6 x 3/4" self-tapping screw (provided) in the hole located at the inboard end of the mounting bracket slot. Drill a 1/16" pilot hole. Drill only as deep as the screw length. Fill the hole with roof sealant and install the #6 screws

6. Install the brackets, this time placing
the 1/4 - 20 carriage bolts through the slot
in the bracket with the threads facing
upward. Now fasten the bracket to the
vent sidewall with the #6 x 1/2" machine
screws provided. (D) Place the flat wash-
ers, lock washers and nuts inside the
vent wall (D1 ).

7. The air-sealing foam gasket must be
applied at this time of the installation.
Avoid stretching the gasket as you
remove the paper backing. Place the
adhesive side down against the plastic
flange of the Turbo/Maxx as shown in (E).
If your gasket needs to be trimmed, cut it
to size with ordinary household scissors.
Be certain there are no gaps that may
detract from the Turbo/Maxx's ability to
pull air from the cabin. Gaps around the
D1
brackets after the installation is complete
are acceptable. It is neither necessary
nor is it recommended to apply caulking
around this gasket area.

8. Drill a 3/8" hole for the fan's power cord
near the bracket at the front passenger
side of the RV vent side wall (F). Drill as
high as the vent lid will allow when it is in
the closed position. Insert the four control
wires (one at a time) into the 3/8" hole (F1
F1
and F2 ). Slide the locking clip provided in
the hardware kit over the wires and press
it firmly over the molded restraint (F3 and
F4). Slide the clip so that it fits tightly
against the inside wall of the vent (F5).
F2
9. Make certain the wires clear the vent
lid as it closes and place the Turbo/Maxx
over the 1/4-20 stainless steel carriage
bolts previously installed in the mounting
brackets. Fasten the Turbo/Maxx with the
1/4" lock washers, flat washers and hex
nuts. You may need to press down on the
housing to compress the foam gasket
allowing more room to engage the nuts
F3
and washers (G and G1).
The outside installation is now complete.

After making certain the power is turned off, provide a 12 volt DC power source to the front passenger side of the roof vent. This is the same corner that the Turbo/Maxx power cord enters the vent from the roof.
10. Drill a clearance hole or file a notch in the existing roof vent screen frame and pull the power cord from the Turbo/Maxx and the two 12 volt DC power wires to the inside of the vehicle. A notch may be preferred as it allows future removal of the screen. Some frames have enough clearance to allow wires to fit between the frame and the roof opening. In that event, a hole in the trim ring may be all that is required. (H and H1)
11. Before installing the control console you must be certain to identify your vehicle 12 volt positive (+) and 12 volt negative (-) power supply wires. If you are unsure how to use a volt meter to identify the polarity of the vehicle 12 volt power that you are connecting to the Turbo/Maxx control console, consult a qualified RV Technician.

14. Connect the four wires from the Turbo/Maxx power cable to the PC board in the control box. These terminals marked FAN are located near the center of the board. Push the white wire (smaller female terminal) onto the horizontal male terminal labeled WHITE COM. Connect the green wire to the horizontal male terminal labeled GREEN LOW, the red wire to the horizontal male terminal labeled RED MED and the black wire to the horizontal male terminal labeled BLACK HIGH. (I)
15. Prior to attaching the control console to the trim ring, test your Turbo/Maxx according to the following instructions:
Put the fan speed control knob in the OFF
I
position and open your vent lid. Turn on
the 12 volt power to the Turbo/Maxx. Note
- If the red light inside your control console
is lit, you have a reversed polarity condi-
tion. Turn off the power and re-attach the
power leads to the correct terminals on the
console. Turn on the power and the light
should be off. Although reversed polarity
will not harm this control, the motor will run
backwards. If you have a Model 1200T
with thermostat, turn the thermostat control
fully clockwise. With the Air Direction
intake/exhaust rocker switch in the IN posi-
tion turn your Fan Speed control knob to
position one (1), then two (2) and finally
(3). At each setting, the fan speed should
increase with the three (3) setting being the
maximum speed attainable. Air should be
blowing INTO your vehicle. Now turn the
speed control knob to OFF and the rocker
switch to OUT. Air should be drawn out of
the vehicle at the various speeds. It is rec-
ommended that you operate the
Turbo/Maxx with your vent lid open to allow
for maximum ventilation.

If your fan speeds or other functions do not operate as described, review your wire connections and polarity assessment. If you have a thermostat model, refer to the attached operating guide for further information.
If you are satisfied that the control console is functioning properly, proceed to the installation on the vent trim ring.
16. Turn off the 12 volt power. Place the control console up against the forward passenger side of the trim ring so that the flange of the control console overlaps the flange of the trim ring (J). Mark the three hole positions with a pencil on to the trim ring flange. Allow the control console to hang free by the wires and carefully drill a 1/16" hole at each of your pencil marks. Install the control console protective shield into the control console housing as viewed in (K). Be certain the 12 volt +/- power wires run under the cover screw tab in that area. Bundle extra wire into the area shown. Hold the console in place per the photo (L) and attach it with the three #6 self-tapping screws provided. DO NOT over-tighten them! Your console should look like the photos in L1 and L2. (Note the Thermostat Model 1200T is shown.)
Note: If your vent has a shallow screen depth that will not accept the console wall; or should your screen be flush with the ceiling trim ring, make an outline of the console by holding it against the screen and carefully trace the shape onto the screen fabric. Using an appropriate tool, neatly cut the screen fabric to allow the console to pass tightly through the screen.

Factory Tested
Every Turbo/Maxx ventilator is tested at the factory to ensure proper operation prior to shipment.
Power Consumption
The Turbo/Maxx draws less than 4 amps at high speed (#3 setting) using 13.8 volts DC of power and under 1.4 amps at the lowest speed (#1 setting).
Fuse Protection
The control console is protected by a factory-installed 10 amp non-reset replaceable minifuse (located on the PC Board under the polarity light), a non-resettable fuse on the resistor board and an overheat protection switch within the motor. The Turbo/Maxx must also be connected to power wires that are fuse protected within the RV. We recommend a maximum of 10 amps fuse protection to this device.
Air Flow Direction
The IN-OUT air direction switch is referred to as the "Rocker" switch. It changes the direction of the fan motor so that you may either pull air into the cabin or draw air out. It is imperative that the vent lid is open, and some other vent or window is also at least partially open to allow the powerful Turbo/Maxx motor to cool itself and to operate efficiently. Be sure to leave a window or other air vent open to give the Turbo/Maxx some fresh air to work with. This should be at a distance from the ventilator so that fresh air can travel through the entire living area before being exhausted by the Turbo/Maxx. Our Window/Maxx for sliding windows makes an ideal companion product for cross ventilation.
Minimize Wear
When changing fan direction, it is advisable to stop the fan by turning the three-speed knob to the OFF position and wait about ten seconds before restarting the fan in the opposite direction.
Thermostat Control (for Model 1200T only)
The overall temperature range of the thermostat on the 1200T model is set at the factory. Unless the Speed Control switch is in the "OFF" position, the Turbo/Maxx 1200T will be fully operable between 20 degrees F and 120 degrees F. To operate, set the fan to exhaust and turn the thermostat fully clockwise ("COOLER'). The fan should now be running. Slowly turn the thermostat counter clockwise until the fan just stops running. The thermostat has now "measured" the RV's existing temperature. The thermostat is designed to allow the RV interior temperature to rise approximately 5 degrees F from this setting before the fan will automatically restart and draw air into the RV from the outside. Turning the thermostat slightly more will increase this 5 degree range. When cooler air is drawn into the RV and the RV's interior temperature reaches its original setting the fan will automatically shut off. Positioning the thermostat knob fully clockwise ("COOLER") will allow the fan to run constantly.
CAUTION!
When working on a Turbo/Maxx (cleaning the screen or fan blade), be certain to turn the speed control knob to the OFF position to avoid accidental starting. It would be advisable to turn the 12 volt vehicle power to the Turbo/Maxx OFF to be sure you are safe.
Trouble Shooting Guide
The Customer Service phone number for MaxxAir is 800-780-9893, email is maxxair@maxxair.com
Any trouble shooting of the Turbo/Maxx should be carried out after the wires have been completely disconnected from the printed circuit board (pcb) for at least ten (10) minutes.
A sudden surge of power from another power source or the shorting or switching of two power wires connected at the PC board can severely damage it and jeopardize your own safety. Some system components run normally hot to the touch and should be allowed to cool prior to trouble shooting.
A circuit failure may appear to be the same as a blown fuse. Turn off your motor at the control box and your 12 volt power to the Turbo/Maxx. Check your fuses first. Resistor board components get hot even during normal operation. Do not put your hands in the motor/fan blade area withing ten (10) minutes of shutting the unit off. The control console contains an automotive 10 amp mini-fuse. To gain access to this fuse, the console must be removed from the ceiling. Lift the control circuit board cover to replace the fuse. Caution: a blown fuse may indicate a severe electrical problem in your RV. You may wish to contact an RV Technician for assistance.
Should your Turbo/Maxx run on the incorrect speed setting, you probably have an incorrect 12 volt wire hook-up. Call MaxxAir's Customer Service Dept. for guidance, or review previous wiring instructions and make corrections as needed.
If the fan motor does not run, check the following:
1. Reconfirm the 12 volt power source polarity has been correctly connected to the proper terminals.
2. Use a volt meter or 12 volt test light to confirm 12 volt power is available at the power supply wires.
3. Disconnect all wires from the control box PC board and connect the 12 volt supply
directly to the black and white fan motor leads. If the fan runs, you may have a problem with
the PC or resistor boards. If the
fan motor does not run, check for loose terminal
connections on the roof that are located inside the Turbo/Maxx housing. DO NOT CHANGE
WIRES AROUND! Your Turbo/Maxx was tested at the factory.
The state-of-the-art resistor board that is attached to your housing is protected by a 10 amp nonresettable fuse that will cut all power to the unit in the event circuit failure is experienced by the board. Jamming of the fan blade or an abnormal electrical occurrence can over-tax the fan motor or resistor board, creating excessive heat that will shut down specific components. These are not user serviceable parts and we suggest you call Customer Service for further instructions.
Once you are satisfied you have corrected a problem, the fan speed control should be switched to the OFF position for a minimum of five (5) minutes before restarting the system. This will allow the circuit and thermal cut-out device in the motor to cool and automatically reset.
