system are operating correctly. Poor batteries or charging system may result in the fan
or controller to function improperly.**
Install the temp. probe near the inlet hose,

Initial Start-up and Adjustment Procedures
Turn ignition on. After 6 seconds, LED #L4 should light up. If not, check to make sure that there is 12 volts at1. terminal #9 on the Fan Motor Control. The delay is to allow the starter to start the vehicle without the fans drawing
any power.
With the engine running, engage the A/C. The fans should come on and cycle with theA/C clutch. LED’s #L1,
2. L3 and L4 should be lit when the fans are running. If they do not turn on, verify that the A/C clutch is engaged
and make sure you have a positive signal when the clutch is engaged at terminal #8 on the Fan Motor Control.
Shut offA/C and let engine continue to idle, or drive the vehicle a short distance to bring the engine to operating
temperature (monitor the vehicle’s temperature gauge).
Verify that operating temperature has been reached by feeling the upper radiator hose. Hot water should be

owing through the hose into the radiator. If the fans have not cycled on yet, slowly adjust the screw on the Fan
Motor Control until the fans cycle on. Turning the screw further in this direction will keep the engine at a lower
temperature, and turning in the opposite direction will keep the engine at a higher temperature.
NOTE: THE TOTAL MOVEMENT OF THE ADJUSTMENT SCREW IS ABOUT 3/4 OF A TURN. TURNING THE
SCREW BEYOND THE LIMITS WILL DAMAGE THE UNIT!
Once the desired temperature is set, let the engine continue to idle and make sure the fans will cycle to maintain
desired temperature. When the fans are running, LED’s #L1 and L4 should be lit.
Disconnect the VSC when charging your vehicle’s battery, or batteries, from an exterior source.
If the vehicle requires a jump start or remote battery charger to start the vehicle, the VSC may be
damaged by a power surge not normally experienced by the vehicle’s electrical system.
We recommend disconnecting both positive and negative leads to the controller prior to jump starting or
charging the vehicles electrical system.
Electrical Surge Warning:
Turning screw counterclockwise = cooler temp.
Turning screw clockwise = warmer temp.
