you do not have to change the cam settings from the factory
settings. However, you may have to synchronize the cams. If
the actuator is out of synchronization.
• the actuator will rotate in the wrong direction in relation
to its controller (as in a solar heating system)
• one actuator will rotate incorrectly in relation to another
actuator (as in pool/spa combination)
Figure 18. JVA Synchronization, Example
Suction Return
Spa Spa Pool Pool
For a pool/spa combination, synchronize the valve and the
actuator before activation (see Figure 18).
To synchronize the valve and the actuator:
1. Flip the toggle switch located on the bottom of the
actuator to the ON 2 position (see Figure 19). The toggle
positions are marked on the actuator cover.
2. Retry the system.

3.5.4 Resetting the Cams
WARNING
Improper cam settings can result in dead heading
of the water flow which can cause injury or property
damage. Improper cam settings and/or operation will
void the warranty.
NOTE: Before resetting cams, if the valve is plumbed
in Standard Plumbing position and the actuator
is in Standard Mounting position (see Figure
3). There is no need for resetting the cams. If a
port other than “B” is plumbed as the common
port or if the actuator is mounted other than
Standard Mounting, the cam setting must be
changed so the actuator shaft and the valve
diverter rotate properly. Refer to the Cam
Setting Chart for proper settings.
1. Turn OFF actuator power. Unscrew the locking knob by
turning the knob counterclockwise. Remove the locking
knob and valve handle.
2. Remove the four (4) Phillips head screws that secure the
actuator lid and then remove the lid.
3. 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 20).

4. Determine the mounting position for the actuator (as
per Figure 3, the mounting position will be either I,
II, III, or IV). Next, determine what valve port is the
common or inlet port (per Figure 3, the common port
will be either A, B, or C). Refer to the Cam Setting Chart
to determine what the cam settings should be.
5. For example, if the actuator is in JVA mounting position
“I”, and the common port on the valve is port “A”, the
cam settings would be 90° for the top cam and 180° for
the bottom.
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.
6. To set the cams, rotate the cam(s) until the arrow mark
on the cam(s) align with the microswitch actuator (see
Figure 21).

Rotate Cams
NOTE: The upper cam stops counterclockwise rotation
and the lower cam stops clockwise rotation.
7. Turn power ON to the actuator and use the toggle switch
located on the bottom of the actuator to check rotation.
8. Move the toggle switch to either ON 1 or ON 2. Allow
the actuator shaft to move until it stops.
9. Check valve diverter position*, if the position is correct
flip the toggle switch in the opposite direction and allow
