1. Unscrew the hold-down knob and remove handle from valve
shaft. Set aside the knob and handle for later use.
2. With a Phillips screwdriver, remove the four screws from the
valve body as shown in Figure 1.
3. Turn the actuator over and observe the teeth as shown in
Figure 2.
4. Place the actuator over the valve shaft so the small tooth
engages with the small slot in the valve shaft. See Figure 2.
5. Rotate the actuator until the actuator posts line up with the four
holes so it matches one of the mounting positions shown in
Figure 3. See table below for descriptions of mounting options.
Mounting Options
The actuator can also be mounted on top of a valve in fourdifferent
positions as shown in Figure 3. Depending on the plumbing of the
valve and mounting position of the actuator, the cams inside the
actuator may have to be reset. (See next section.)
6. Use the supplied four long stainless steel screws to attach the
actuator to the valve.
7. Use the hold-down knob set aside in step 1 to connect the
handle to the valve shaft.
8. Connect power supply cord to a CLASS 2 CIRCUIT ONLY,
rated 24V nominal, 4A or 100VA maximum.
Place actuator on valve so small tooth aligns
with small slot.

ELECTRICAL RATINGS : 24Volts, 60 Hz, 0.75 Amps.
Normal Operation Duty Cycle: 1 minute ON (Max), 8 minutesOFF (Min). These
values maybe temporarily exceeded during installation testing and adjustment.
Standard Plumbing - Athree-port valve is the port B (middle)
being the incoming (common) port and A and C ports are the outlet
ports (see Figure 1).
Standard Actuator Mounting - The main body of the actuator
is over port B as shownin ItemII of Figure 3.

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
rotation 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).

OPERATION
During the normal operating season, the valves may need to be rotated manually, such as draining or filling the pool/spa.
The valves can be rotated electrically or manually. If the system has power, rotate electrically. If no power, rotate manually.
Rotating Valve Actuator Electrically
1. At the rear of the Actuator, toggle the valve switch until the desired rotation is reached. See Figure 7 on previous page.
2. Toggle the switch to the center (OFF) position to stop rotation.
3. Toggle the switch back to its original position.
Rotating Valve Actuator Manually
1. At the rear of the valve actuator, toggle the switch to the center (OFF) position.
2. Loosen the hand-locking knob four full turns.
3. Press down firmly on the locking knob to disengage the actuator gear train from the valve shaft.
4. Turn the handle to rotate the actuator valve to an Auto ON position.
5. Pull up on the handle and turn it gently back and forth to return to the operating (drive) condition.
6. Tighten the locking knob on the top of the handle and toggle the switch to its original Auto ON position .
Servicing the Valve Actuator
The valve actuator seals need to be greased once a year. The lip
seal is located under the actuator, where the shaft exits the lower
housing, with two ring seals in the lid, where the shaft exits at the
top. Use only silicon base lubricant, suitable for the purpose.
1. At the rear of the valve actuator, toggle the switch to the
center (OFF) position. See Figure 7.
2. Loosen the hand-locking knob four full turns.
3. Press down on the locking knob to force the actuator shaft
into the manual state.
4. Apply a small amount of silicon lubricant with a small brush
around the exposed portion of the shaft between the bottom
of the actuator and the top of the valve.
5. Turn the handle around twice to spread lubricant evenly.
6. Pull handle to ensure gears are engaged and actuator is in
Auto state.
7. Remove locking nut and handle and apply a small amount of
lubricant around the shaft, where it exits the lid.
8. Reinstall handle and toggle switch to desired AUTO position.
