STEP 4
Align the control arm of the Venturi Valve so that it is straight vertical and verify that
the potentiometer is at the center of its rotation. Do this by rotating the potentiometer

point, before proceeding to step 5.
STEP 5
Slide the shaft coupler onto the POT & rotating pin, such that the coupler clamps onto
each shaft as shown. Tighten the 2 hex screws.
STEP 6
Move the valve control arm to verify that the POT, coupler and rotating pin do not slip.
Route and connect POT wires to controller.
