1. Determine the COMMON and EXIT port(s) of the valve.
2. Remove the four screws and actuator lid to locate the cam/
motor compartment. See Figure 4 to observe the cam.
3. Push down and rotate the actuator shaft (see Figure 4) so the
0 degree mark lines up with the arrow on the switch hous -
ing and the bottom cam lines up with the arrow as shown in
Figure 5.
4. Refer to the Cam Adjustment Table below to find the proper
cam settings and then loosen the locking nut 1/4 turn coun -
terclockwise and line up the specified marking on the cams
with the arrows on the switch housings to reset the cams.
See Figure 5.
5. Tighten the locking nut and then check the cam settings and
the tightness of the shaft assembly.
6. Apply power to the valve actuator(s) and then check the valve
rota tion and stop positions.
7. Make adjustments if necessary. Refer to the Synchronization
section and Troubleshooting section if problems persist.
8. Replace lid and verify screws and assembly are watertight.
9. Install the handle and test operation.
Synchronization
The Actuator is out of sync if it is rotating in the wrong direc -
tion in respect to its controller or another Actuator. In order to
synchronize the system, connect Actuator(s) to the controller
and observe the function. If an Actuator is out of sync, flip the
3-position switch at rear of Actuator to extreme opposite posi -
tion. An example of how actuators can be out of synchronization
is explained below.
Figure 6 on the right represents the valves and actuators for a
pool/spa combination. The valve on the left (spa on left and pool
on right) is plumbed just the opposite as the one on the right
(pool on left and spa on right). If the actuators are now activated,
one will turn to spa while the other is turning to pool. Changing
the cam settings within the actuator will not correct this problem.
To synchronize the actuators, flip the toggle switch at the rear of
the actuator (which is out of sync) to the extreme opposite posi -
tion. (See figure 7. Note: center position is OFF).
