P5 MOUNTING INSTRUCTIONS
3.2 Mounting Instructions
1. Remove the knob and handle from the valve
2. Refer to to determine which four screws
to remove.
3. Place the valve handle on the actuator shaft
and tighten the knob.
4. Align the smallest tooth on the actuator shaft
with the smallest slot on the valve diverter.
5. With the two shafts engaged, rotate the
actuator until the holes on the actuator align
with the screw holes on the cover.
6. Using the 4 long screws (M6x55) provided to
secure it in place. .

Do not over-tighten

Factory default is matched with standard
mount. If the valve is connected in a standard
installation, there is no need to perform a cam
adjustment.
Note:

3.4 Advanced Cam Setting
1. Move the toggle switch to OFF (Centre) position.
2. Remove the knob and the handle from the actuator shaft.
3. Remove four screws on the actuator and open the cover.
4. The cams are located under the cover bushing and on the actuator shaft. Slide the cams off the shaft
splines and rotate them to the desired position. Refer to the chart in Basic Cam Settings for determining
the position of the cam.
Fig. 4

P6 SYNCHRONIZATION
5. For advanced cam settings, the design of the shaft has
been divided into 28 directions to customize water flow for
your installation. Each of them is around 13 degrees from the
other. Users may select partial open, semi-open, partial close,
etc.). These settings are not listed in the chart. The 12 o’clock
(small slot) is always the reference of every setting (Fig. 2).
The upper cam affects the clockwise position stop point. The
lower cam affects the counter-clockwise rotation stop point.
6. The toggle switch on the bottom of the valve actuator can
be used to verify if the new adjustment is correct (switch
between ON1 and ON2).
7. Replace cover and handle and tighten screws and the
locking knob.
8. Put toggle switch back to ON1 or ON2 position.the
Fig. 5
Advanced cam setting should be performed by pool technician.
Note:
3.5 Synchronization
A typical pool with a spa might have 3-6 diverter valves to control the flow of water through the pool
and spa. If one is rotating in the opposite direction to the other, the actuators have to be adjusted to
bring them into Sync. Simply flip the toggle switch of the Actuator between ON1 and ON2.
3.6 Manual Override (MO)
Turn power OFF to all filtration pumps before doing this action, to minimize the
possibility of any injury or damage.
CAUTION
1. Turn the toggle switch to the OFF position.
2. Unscrew anti clockwise the knob for 1 turn approximately.
3. Push down the handle and knob. This will disengage the gear train and allow the handle, thus the
diverter, to move to any position.
4. Make sure to turn the actuator to the automatic position after manual override. Turn clockwise or
counter clockwise slightly until you feel the shaft slide up into the gear train. Then, turn the knob
clockwise to lock the handle.
5. Tighten the knob.
6. Flip toggle switch back to the original position.
The valve position may have to be adjusted manually when necessary. This happens when the controller
is not accessible or following a power failure. Follow the instructions below.

4. MAINTENANCE
P7 MAINTENANCE
The FLEX Valve Actuator has 2 seals which require lubrication once a year. These seals are located at the
top and bottom of the actuator, where the shaft exits the actuator housing. Please follow the steps to
lubricate those seals:
Lubricate
1. Turn the actuator power OFF.
2. Remove the knob and the handle.
3. Spread a small amount of silicone base lubricant around the
actuator shaft where it enters the cover (See Fig. 6).
4. Reinstall the handle and knob, do not over-tighten.
5. Push down on the knob and handle to force the actuator
into manual override.
6. Spread a small amount of lubricant around the actuator shaft
where it protrudes from the bottom of the actuator.
7. Turn the handle once around to spread the lubricant.
8. Pull up on the handle and let it click into place.
9. Tighten the knob.
Fig. 6
To avoid electric shock which can result in property damage, severe injury or
death, disconnect power to the system at the main circuit breaker before
servicing.
To minimize the risk of injury and avoid damage to the equipment, use a properly
sized, listed Class 2 transformer for connection to the power supply.

5. WIRING DIAGRAMS

P8 MAINTENANCE
The internal circuit of the actuator is based on a motor that turns the valve, 2 limit switches, to know the
2 stop positions, a capacitor, for possible peaks in the line, and a switch controlling the tension of the
red wire (turn one way) or white wire (turn the other way).
In the following image, you can see how the connection of the 2 actuators would be. For each
connected actuator, the amperage will rise by about 1A and the fuse will have to be modified.

P9 TROUBLESHOOTING
6. TROUBLESHOOTING
Problem
Cause
Solution
The actuator handle
oscillates.
Lack of valve seal lubrication.
Obstruction in the valve body
Lubricate valve. See the
“Maintenance” section.
The actuator motor works but
the valve diverter does not
turn.
The actuator shaft has
broken.
Replace the actuator shaft.
Actuator in manual position.
Pull up on the handle while
rotating.
The gear train was damaged.
Replace gear or shaft.
The actuator motor does not
turn.
No power to the actuator.
Check voltage between black
(common) wire and each
switch leg (red, white)
Toggle switch in the OFF
position.
Flip toggle switch to ON 1 or
ON 2 positions.
The motor has failed.
Replace motor.
Failed or broken microswitch.
Replace microswitch.
Both cams are in contact with
their microswitches.
Check the cam setting
section.
The actuator rotates in one
direction but not back again.
