Description
Jandy Valve Actuators are designed to meet the
needs of today's more advanced, automatic pool
equipment. These fully adjustable actuators offer
versatile pool/spa automation with easy setups.
All actuators work with the Jandy AquaLink
®
RS
Control Systems and are available in 24 volt units.

Section 3. JVA Mounting Positions
3.1
Standard JVA Position
Standard Plumbing position is with the middle
port (B) as the incoming or common port to the
valve (see Figure 1).
Standard Mounting position is with the main
body of the actuator over port B (see Figure 2).
NOTE If the valve(s) are plumbed with port B as the
common port (Standard Plumbing) and the
main body of the actuator(s) are mounted over
port B (Standard Mounting), there is no need to
adjust the actuator cams. Page 6
3. Turn the actuator over so you can see into
the clear actuator shaft. There are four (4)
"teeth" on the inside of the shaft. Locate the
smallest "tooth" and align this "tooth" with
the smallest slot on the valve (see Figure 5).

1. Unscrew the locking knob by turning
the knob counterclockwise. Remove the
locking knob and valve handle (see Figure
4).
2. Remove the four (4) large Phillips head
screws from the valve. The location of the
screws you remove will determine how the
actuator will be mounted (see Figure 4).

Actuator Mounting
JVAs mount directly on all full-size Jandy Valves
(8 screws on lid) and can be adapted to mount on
Jandy Space Saver Valves (4 screws on lid). Jandy

only.
JVAs may be mounted onto valves in any of the
four (4) positions in Figure 3.

4. Place the actuator onto the valve.
5. Rotate the actuator while keeping the two
shafts engaged until the screw holes on the
actuator legs align with the empty screw
holes (from step 2) in the valve (see Figure
6).
6. Use the four (4) large 2" Phillips head
screws (included with the JVA) to secure
the JVA to the valve.
7. Put the valve handle on the actuator shaft.
Put the knob on the shaft and tighten
(finger tighten only).

On the actuator that is out of synchronization, flip
the toggle switch located on the bottom of the
actuator to the ON 2 position (see Figure 8). The
toggle positions are marked on the actuator top
cover. Retry the system.
3.2
Resetting the Cams
NOTE Before resetting cams, if the valve is plumbed in
Standard Plumbing position and the actuator
is in
Standard Mounting position there is no
need for resetting the cams (see Figure 9). 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 on page 8 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.
3.1
Synchronization Methods
If the valve is plumbed in the Standard Plumbing
position and the actuator is mounted in Standard
Mounting position, you do not have to change the
cam settings from the factory settings. However,
you may have to synchronize the cams.
One of the following will occur when 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 7 illustrates an example of the valves and
actuators of a pool/spa combination that are out
of synchronization. The valve on the left of the
illustration (suction) is plumbed with the spa line
on the left side of the valve and
