PWM ELECTRIC FAN CONTROLLER

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
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.
