(Page 1)
IMPORTANT NOTES
This fan controller has been completely quality control tested prior to final packaging.
MAXIMUM CAPACITY: 70 AMPS
This controller will operate multiple fans with a combined maximum amperage up to 70 amps. On dual fan applications, it is
important to know your fan(s) amp draw before installing, if fan(s) exceed 70 amps, all warranty will be void.
AUTO RESETTING CIRCUIT BREAKER
The fan controller utilizes a 50 amp auto resetting circuit breaker to protect the fan(s) and controller circuit. In the event of an
electrical issue, the breaker will “trip” and open the connection between the battery and the controller. The circuit breaker will
automatically reset once the issue has been corrected. If installing fan(s) exceeding 50 amps in total you must use a fuse or
circuit breaker suitable for your systems amp draw.
MAIN POWER CONNECTIONS
The positive and negative wires feeding the fan controller MUST be connected directly to the vehicles battery.
This is very important because the controller requires a clean signal, do not connect directly to the fuse panel, starter or the
alternator.
VEHICLES BATTERY LOCATION
If the vehicles battery is located more than 5 feet from the fan controller, the signal could encounter some interference or noise,
which causes a dirty signal. In some cases, a larger 6 gauge wire may be required. Please contact our technical support team
for more information. (323) 266-3850 or [email protected]
TEMP SENSOR
This unit is equipped with a newly released aluminum temp sensor that reacts 50% quicker than previous models. It uses 3M
double stick tape to adhere right to the radiator tank, therefore getting a very accurate temperature reading. The surface
preparation is critical; surface must be absolutely free of dirt, oil, peeling paint or any contaminants to ensure a proper bond.
Important: The ideal application temperature range is 70°F to 100°F (21°C to 38°C).The minimum suggested application
temperature is 50°F (10°C). At 70°F approximately 50% of the ultimate bond strength will be achieved after 20 minutes, 90%
after 24 hours and 100% after 72 hours.
OVERRIDE CIRCUIT
The fan controller has an override circuit (Green Wire) available that when activated, will ramp up the electric fans to 60%
running speed. As the engine temperature increases the fans will increase accordingly.
WIRE CONNECTIONS
Crimp connections are critical to the function of this controller, please ensure that all connections are made using quality
crimpers. After each crimp has been completed, tug wires, there should be no movement within the connector. Ground
connectors are crucial. If grounding to chassis we do not recommend using self tapping screws as they tend to loosen
over time.
COOL DOWN FUNCTION
This PWM fan controller is designed with a cool down function that will allow the electric fan(s) to run for 20 seconds after the
vehicle has been turned off.

FAN CONTROLLER INSTALLATION
1. Choose a convenient location, preferably along the vehicles core support near
the battery. Take in to consideration sensor placement & wire routing
requirements. Avoid mounting near HOT engine components or a location that
would be in direct contact with any road debris.
2. Using the fan controller as a template, mark and drill four 5/32” holes in
the proper location.
3. Using four #10 sheet metal screws supplied, secure the unit in place.
CIRCUIT BREAKER MOUNTING
1. Choose a convenient location for the circuit breaker that is between the fan
controller and the battery.
2. Using the circuit breaker as a template, mark and drill two 5/32” holes in the
proper locations.
3. Using the remaining two #10 sheet metal screws supplied, secure the circuit
breaker in place.
SENSOR INSTALLATION
1) Determine the desired mounting location of the sensor, somewhere on the
radiator near the water inlet. (See Diagram #1)
2) Route the path of the sensor wires from the controller to the radiator. If
necessary, you can lengthen or shorten the wires using an automotive grade
22-gauge wire.
3) Once you have routed the wires and have the sensor location chosen, clean
and dry the area with alcohol, making sure there is no left over residue.

4) Remove the Red 3M backing paper from the sensor and install the sensor in the desired location, applying firm pressure for
at least 15 seconds.
NOTE: This unit uses 3M double stick tape to adhere right to the radiator tank, therefore getting a very accurate temperature
reading. The surface preparation is critical; surface must be absolutely free of dirt, oil, peeling paint or any contaminants to
ensure a proper bond.
The Ideal application temperature range is 70°F to 100°F (21°C to 38°C).The Minimum suggested application temperature is
50°F (10°C). At 70°F approximately 50% of ultimate bond strength will be achieved after 20 minutes, 90% after 24 hours and
100% after 72 hours.
WIRING
Before starting, disconnect the negative (-) cable on the vehicles battery.
Using the electrical connectors and wire ties provided, follow the instructions below.
WARNING: The positive and negative wires feeding the controller MUST be connected directly to the vehicles battery.
This is very important because the controller requires a clean signal, do not connect directly to the fuse panel, starter or the
alternator. Improper installation will void the warranty.
1. Using a yellow 5/16” ring terminal & 10 AWG Red Wire supplied, connect one end of the Red Wire to the vehicles positive
(+) terminal on the battery.
2. Route the 10 AWG Red Wire now connected to the battery to the circuit breaker previously installed and cut the wire to the
appropriate length.
3. Using a yellow #10 ring terminal, connect the 10 AWG Red Wire to the “BAT” (Copper Colored) terminal on the circuit
breaker.
4. Using a yellow #10 ring terminal, connect the auxiliary side “AUX” (Silver Colored) of the circuit breaker to the length of 10
AWG Red Wire of the controller wire harness.
5. Using a Yellow Butt Connector connect the Blue Wire from the controllers wire harness to the Positive Wire(s) of the
Electric Fan(s) being controlled.
6. Using the 5/16 Yellow Ring Terminal connect the 10 AWG Black Wire from the controllers wire harness direct to the
batteries negative terminal.
7. Connect the electric fan(s) being controlled direct to the negative stud or a good chassis ground. Use the shortest wire
route possible.
8. Using a Blue Wire Tap connector attach the Yellow Wire to a Positive (+) switched ignition source.

Green Wire: Override Circuit (Optional)
The green wire is designed to work in two different configurations. When used, this will allow the electric fan(s) to be turned on
regardless of the temperature of the cooling system. The fan speed will quickly ramp up to 60% and will operate between 60
and 100% as temperature increases and decreases. Connect the Green wire to either option A or B below.
Note: Use of the Override is optional and not required for the PWM controller to work properly.
A. A/C Override - Using the provided, attach the green wire to a positive (+) 12V output on the blue wire tap connector A/C
High Pressure Switch.
B. Manual Switch Override - Attach the green wire to the 12V output on the manual switch (not provided.)
VEHICLE TESTING
1. Before you start the vehicle, make sure all wires are safely zip tied and away from any moving parts.
2. Start the vehicle.
3. If the manual override function is being used, turn on the A/C or manual switch. Electric fan(s) will ramp up to 60%.
4. Turn off the manual override or A/C function and allow the engine to warm up, fans will ramp up slowly as the vehicle warms up.
(Page 3)
ADJUSTING THE TURN-ON TEMPERATURE
The PWM Controller is factory set at approximately 180°F. Therefore Fans will adjust
speed to maintain 180°F fluid temperature. Using the adjustment screw on side of the
controller the temperature can be adjusted to maintain fluid temperatures from
130°F - 230°F. Follow the directions below to make adjustments to the temperature.
1. Remove the rubber plug from the side of the fan controller
2. Using a 1/8” blade screwdriver, follow the instructions below:
If your engine is running too cool: Turn the adjustment screw CLOCKWISE in
increments of 2 FULL turns, then test before
repeating.
If your engine is running too hot: Turn the adjustment screw COUNTER-CLOCKWISE in
increments of 2 FULL turns, then test before repeating.
