8. Manual Switch
If manual switches (Flex-a-lite #31148) have been purchased, attach them as follows: To override
engine temperature signal and turn fans off, connect the switch to terminal #5 on VSC to send a
negative (-) signal. To override engine temperature signal and turn fans on, connect the switch to
terminal #6 on the VSC so that a negative (-) signal is sent.
The Variable Speed Control has new features.
At the set temperature, the fans will come on at 60%; this reduces the load on your charging
system. If the temperature rises, the fan speed will increase. If your set temperature is 195°F, then
between 195° and 205° the fan speed will increase from 60% to 100%. So after a 10-degree rise from
the set point, the fans will be running at 100%.
Initial Start-up and Adjustment Procedure
1. Turn ignition on. After 6 seconds, LED #L4 should light up (Refer to wiring connections diagram). If
not, check to make sure that there is 12 Volts at terminal #9 on VSC. The delay is to allow
starter to start the vehicle without the fans drawing any power.
2. With your engine running, engage the A/C. The fans should come on and cycle with the A/C compressor.
LED’s #L1, L3 and L4 should be lit when 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
VSC. Shut off A/C and let engine continue to idle, or drive the vehicle a short distance to bring the engine
to operating temperature (IMPORTANT: You must monitor the vehicles temperature gauge).
3. Verify that operating temperature has been reached by feeling the upper radiator hose. Hot water should
be flowing through hose into the radiator. If the fans have not cycled on yet, slowly adjust the screw on the
VSC 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. (See VSC
Diagram) NOTE: THE TOTAL MOVEMENT OF THE ADJUSTMENT SCREW IS ABOUT ¾ OF A TURN.
TURNING THE SCREW BEYOND THE LIMITS WILL DAMAGE THE UNIT! Once desired temperature is
set, let the engine continue to idle and make sure the fans will cycle to maintain desired temperature.
When fans are running, LED’s #L1 and L4 should be lit.
