3.
Important - Rotate the actuator shaft so the
arrow mark on the top cam aligns with the
microswitch actuator (bottom cam arrow mark
should also align with the bottom microswitch
actuator, see Figure 10). Locate the mounting
position for the actuator (as per Figure 9, the
mounting position will be either I, II, III, or IV).
Next, determine what valve port is the common
or inlet port (as per Figure 9, the common port
will be either A, B, or C). Then refer to the
Cam Setting Chart below to determine what
the cam settings should be. For example, if the
actuator is in JVA mounting position
common port on the valve is port "
settings would be 90° for the top cam and 180°
for the bottom.
Final minor adjustments may be necessary

Before resetting cams, always rotate the actuator shaft so the arrow mark on each cam aligns with the pointer above its
microswitch.

Installation and Operation Manual
NOTE
The cam is marked with the arrow at "0", a long hash
mark at the 180° position, and 2 short hash marks at
the 90° and 270° positions.
4.
To set the cams, rotate the cam(s) until the
arrow mark on the cam(s) align with the
microswitch actuator (see Figure 11).
NOTE
The upper cam stops counterclockwise rotation and
the lower cam stops clockwise rotation.
5.
Turn power ON to the actuator and use the
toggle switch located on the bottom of the
actuator to check rotation. Move the toggle
switch to either ON 1 or ON 2. Allow the
actuator shaft to move until it stops. Check
valve diverter position*, if the position is
correct flip the toggle switch in the opposite
direction and allow the shaft to stop again. If
the stop positions are correct, go to step 6. If
they are not, reset the cams until correct.
NOTE
If the actuator does not move in either direction, refer
to Section 6, Troubleshooting.
6.
Replace the lid and tighten screws. Replace the
handle and locking knob.
NOTE
The end of the handle which has the word OFF
embossed on it exactly duplicates the shape of the
valve diverter. When the handle is placed on a valve
or actuator shaft the word OFF will be directly over
the center of the valve diverter.
