This unit utilizes a GROUND switching circuit. The Unit will activate the Electric Fan(s) at one set temperature. It is not designed to have two activating temperature set points. Please read instructions carefully to insure proper installation. WARNING! This unit is designed to control up to 2 electric fans with a combined maximum draw of 25 continuous amps. If fans exceed 25 amps combined, we recommend installing one controller per fan. 1 Control Module Installation Choose a convenient location, preferably along the vehicles core support near the battery. Take in consideration probe placement and wire routing requirements. Avoid mounting near HOT engine components or a location that would be in direct contact with water or road debris. 40/60 Amp Relay Wire Harness Adjustment Screw Using the module as a template, mark and drill two 5/32” holes in the proper location. Using the two #10 sheet metal screws supplied, secure the unit in place.

Push-in Probe The temperature probe should not extend out of the radiator core more than 1/4” and should fit securely in place. Note While installing temperature probe, do not use sharp objects or install in a location with water. Probe will be damaged by water. 3 Wiring Before starting, disconnect the Negative (-) cable on the vehicle’s battery. Plug the wire harness into the fan control module. Using the electrical connectors and wire ties provided, follow the instructions below. Red (Loose Wire): Using the Blue 5/16” Ring Terminal provided, attach one end of the red loose wire to the vehicles Positive (+) terminal on the battery. Loose “Red” Wire Positive (+) Battery Using the Blue Butt Connector provided, attach the other end of the loose red wire to the positive (+) lead on the electric fan. Negative (-) Fan Wire 30 Amp Fuse Red (Fused Harness Wire): Using the Blue #10 Butt Connector provided, attach the Red wire to the Negative (-) lead on the electric fan. If you are running two fans, the red wire can be connected in parallel to both Negative (-) fan leads. Relay (+) 12V Switched Ignition Chassis Ground (-) Override Circuit Black Wire: Using the Blue Ring Terminal provided, attach the black wire to a good chassis ground. Yellow Wire: Using the Red Butt Connector provided, attach the yellow wire to a positive (+) switched ignition source. Note If yellow wire is connected to a constant power source the electric fan will run after vehicle is shut off and could drain battery. Installation Instructions Adjustable Electric Fan Controller HZ-1011 1-800-838-8024 www.cfrperformance.com Green Wire: The green wire is designed to work optionally. When used, this will allow the fan(s) to be turned on regardless of the temperature of the thermostat as it simply overrides all other functions. If you choose to not use this option, cut any exposed copper and tape, or shrink wrap, the end of the wire. A/C Override - Using the Blue Wire Tap provided, attach the green wire to the positive lead on the air conditioning compressor. 4 Temperature Adjustment DO NOT ADJUST TEMPERATURE UNTIL AFTER VEHICLE IS RUNNING! WARNING! Adjustment range is 3/4 turn total rotation. Do not force past the stop or risk voiding warranty! Remove the Rubber Adjustment Plug on the Control Module. Turn adjustment screw counter clockwise to lower the fan turn-on temperature. Turn adjustment screw clockwise to raise the fan turn-on temperature. Replace the Rubber Adjustment Plug. 5 Vehicle Testing Before you start the vehicle, make sure all wires are safely zip tied and away from any moving parts. Start the vehicle. If the electric fan has not turned on, take a Screw Driver and turn the Adjustment Screw counter clockwise in small increments until fan starts. Allow the electric fan to run and shut off automatically, and possibly cycle on again. If the electric fan turns on too early, turn the Adjustment Screw clockwise. Once you have the fan cycling on and off using the control module, take the vehicle for a short test drive. For personal preference, some adjusting may still be necessary. Make sure the Rubber Adjustment Plug is securely in Place. 6 Trouble Shooting Q : Why doesn’t the fan turn on automatically? A : Check all the connectors to make sure contacts are crimped correctly. Check the ground connection to make sure all paint is sanded off and you are getting a metal to metal contact. Using a 12V Test Light, check to make sure the fan has power on the Positive (+) fan lead even when the vehicle is off. Q : Why does the fan run after the engine is turned off? A : Check the Yellow Wire, this wire should be connected to a switched ignition source.
