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.
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)
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.
On/Off Switch is
located on the
bottom of the JVA
Figure 8. JVA Synchronization, Toggle
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.
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 the pool line on
the right; whereas, the valve on the right of the
illustration (return) is plumbed with the pool on
the left side of the valve and the spa on the right.
In this configuration, if the actuators are activated,
one will turn to spa while the other will turn to
pool. The actuators will have to be synchronized.

3. Important - 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
10). Locate the mounting position for the
actuator (as per Figure 9, the mounting
position will be either I, II, III, or IV). Next,
determine what valve port is the common or
inlet port (as per Figure 9, the common port
will be either A, B, or C). Then refer to the
Cam Setting Chart below to determine what
the cam settings should be. 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.
Final minor adjustments may be necessary

Cam
180°
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.
4. To set the cams, rotate the cam(s) until the
arrow mark on the cam(s) align with the
microswitch actuator (see Figure 11).
NOTE The upper cam stops counterclockwise rotation
and the lower cam stops clockwise rotation.
5. Turn power ON to the actuator and use the
toggle switch located on the bottom of the
actuator to check rotation. Move the toggle
switch to either ON 1 or ON 2. Allow the
actuator shaft to move until it stops. Check
valve diverter position*, if the position is
correct ip the toggle switch in the opposite
direction and allow the shaft to stop again.
If the stop positions are correct, go to
step 6. If they are not, reset the cams until
correct.
NOTE If the actuator does not move in either direction,
refer to Section 6, Troubleshooting.
6. Replace the lid and tighten screws. Replace
the handle and locking knob.

Section 4. Manual Operation
4.1 Manual Override
It is sometimes necessary to rotate a valve(s)
without using the system controller. This occurs
when the controller is not accessible/operational
or when the spa or pool/spa combination require
filling or draining.
1. Move toggle switch located on the bottom
of actuator to the OFF (center) position.
2. Unscrew (counterclockwise) the locking
knob above the handle four (4) full turns.
3. Push down on the locking knob (not the
handle). This will disengage the gear train
and allow the handle, and thus the valve
diverter, to be moved to any position.
4. To return the actuator to automatic position,
pull up on the handle while turning it
clockwise or counterclockwise until you
feel the shaft slide up into the gear train.
Turn the locking knob down (clockwise)
until snug.
5. Put toggle switch back to the original
position.
There are two (2) methods of manually rotating
the JVA; one with power on (system operational)
and one with power off (no power to the control
system).
4.2 Manual Override, Power On
1. Move the toggle switch located on the
bottom of the actuator to the opposite
position (ON 1 switch to ON 2 or vice
versa). This will rotate the motor to the
opposite position.
2. Return the toggle switch to the original
position after use.

CAUTION
To prevent damage to your equipment and to
minimize the possibility of any injury resulting from
such damage, make sure that the pool ltration pump
is OFF BEFORE rotating the valve handle.

Section 5. Maintenance
5.1 Actuator
The JVA has three seals which should be lubricated
once a year. One o-ring is located on the bottom
of the actuator where the plastic shaft exits the
housing and two (2) O-rings located in the top
cover near where the shaft exits the top of the
housing. Use the following steps to lubricate the
seals:
1. Turn OFF power to the actuator.
2. Remove the locking knob and handle (see
Figure 13).
Unscrew Locking
Knob and remove
handle
7. Turn handle once around to spread the
lubricant.
8. Pull up on the handle and tighten locking
knob.
5.2 Valve
NOTE This section does not apply to Jandy NeverLube
Valves and non-positive seal valves. NeverLube
Valves and non-positive seal valves can be
identified by the absence of a grease cap.
NeverLube Valves can also be identified by the
name "NeverLube" on the handle.
Since the actuator rotates the valve diverter which
redirects the flow of water, it is imperative that
the seals and the O-rings within the valve body be
lubricated often (at least every three (3) months).
Use the following procedure to lubricate the valve
diverter seals:
1. Turn off all pool/spa equipment.
Lubricate Here
Figure 13. JVA Shaft Seal
3. Spread a small amount of Jandy Lube or
other silicone base lubricant around the
actuator shaft just above the lock out ring
(see Figure 13).
4. Reinstall handle and locking knob. Only
tighten knob one (1) turn.
5. Push down on the locking knob to force the
actuator shaft into manual.
2. Rotate valve handle so the OFF on the
handle is over the word GREASE on the
valve body.
3. Unscrew (counterclockwise) and remove
the black cap of the grease tting.
4. Fill cap with lubricant (Jandy Lube).
5. Replace cap on tting and turn in
(clockwise) until all of the lubricant has
been forced into the valve.
6. Use manual operation to move the handle
from side to side to spread the lubricant
across the seal.
7. Reset the valve handle to its original
position and start the equipment.
Once a year the valve should be disassembled and
the O-ring and valve body inspected for damage.
Thoroughly lubricate the square seal and the Oring. Reassemble the valve.
6. Wipe a small amount of lubricant around
the actuator shaft where it protrudes from
the bottom of the actuator.
