Section 2. General Information

2.1 Introduction

This manual contains information for the proper installation and operation of Jandy® Pro Series Valve Actuators (JVA). Procedures in this manual must be followed exactly. To obtain additional copies of this manual visit www.zodiacpoolsystems.com. For address information, see back cover.

2.2 Description

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 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).

Figure 1. Standard Plumbing

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.

Figure 2. Standard JVA Mounting

3.2 Actuator Mounting

JVA’s mount directly on all full-size Jandy Pro Series Valves (8 screws on lid). Zodiac recommends motorizing Jandy Pro Series Never Lube® Valves only.

JVA’s may be mounted onto valves in any of the four (4) positions in Figure 3.

Figure 3. JVA Mounting Positions.

1. Unscrew the locking knob by turning the knob counterclockwise. Remove the locking knob and valve handle (see Figure 4).

2. For standard valves, 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). When installing the large 3″ valve, it is not necessary to remove any screws. Use the four mounting bosses provided.

Figure 4. Remove Locking Knob and Lid Screws

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).

Figure 5. Actuator Mounting

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).

Figure 6. Actuator Mounting

Section 4. Synchronization

4.1 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 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.

Figure 7. JVA Synchronization, Example

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.

Figure 8. JVA Synchronization, Toggle

4.2 Resetting the Cams

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

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 9. JVA Mounting Positions.

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. 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.

Figure 10. JVA Cams

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 flip 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.

NOTE The end of the handle which has the word OFF embossed on it exactly duplicates the shape of the valve diverter. When the handle is placed on a valve or actuator shaft the word OFF will be directly over the center of the valve diverter.

Cam Setting Chart

NOTE Before resetting cams, always rotate the actuator shaft so the arrow mark on each cam aligns with the pointer above its microswitch.

Figure 11. JVA Cam Adjustment

Section 5. Manual Operation

5.1 Manual Override

It is sometimes necessary to rotate valve(s) manually, 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.

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).

CAUTION

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

5.2 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.

Figure 12. JVA Synchronization, Toggle

5.3 Manual Override, Power Off

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.

Section 6. Maintenance

6.1 Actuator

The JVA has three (3) 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 theshaft 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).

Figure 13. JVA Shaft Seal

3. Spread a small amount of Jandy Pro Series 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.
6. Wipe a small amount of lubricant around the actuator shaft where it protrudes from the bottom of the actuator.
7. Turn handle once around to spread the lubricant.
8. Pull up on the handle and tighten locking knob.

6.2 Valve

NOTE This section does not apply to Jandy Pro Series Never Lube® Valves and non-positive seal valves. Never Lube Valves and non-positive seal valves can be identified by the absence of a grease cap. Never Lube Valves can also be identified by the name “Never Lube” 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.
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 fitting.
4. Fill cap with lubricant (Jandy Lube).
5. Replace cap on fitting 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 O-ring. Reassemble the valve.
