Jandy Pro Series Valve Actuator Installation and Operation ManualSection 4. Synchronization4.1ON 1Synchronization MethodsOFFIf the valve is plumbed in the Standard Plumbingposition and the actuator is mounted in StandardMounting position, you do not have to change the camsettings from the factory settings. However, you mayhave to synchronize the cams.One of the following will occur when the actuator is outof synchronization: the actuator will rotate in the wrong directionin relation to its controller (as in a solar heatingsystem) one actuator will rotate incorrectly in relation toanother actuator (as in pool/spa combination)Figure 7 illustrates an example of the valves andactuators of a pool/spa combination that are out ofsynchronization. The valve on the left of the illustration(suction) is plumbed with the spa line on the left sideof the valve and the pool line on the right; whereas, thevalve on the right of the illustration (return) is plumbedwith the pool on the left side of the valve and the spaon the right. In this configuration, if the actuators areactivated, one will turn to spa while the other will turnto pool. The actuators will have to be synchronized.SuctionSpaENGLISHON 2Page 7On/Off Switch islocated on thebottom of the JVAFigure 8. JVA Synchronization, Toggle4.2Resetting the CamsWARNINGImproper cam settings can result in dead headingof the water flow which can cause injury or propertydamage. Improper cam settings and/or operation willvoid the warranty.NOTE Before resetting cams, if the valve is plumbed inStandard Plumbing position and the actuator is inStandard Mounting position there is no need forresetting the cams (see Figure 9). If a port other than"B" is plumbed as the common port or if the actuatoris mounted other than Standard Mounting, the camsetting must be changed so the actuator shaft andthe valve diverter rotate properly. Refer to the CamSetting Chart on page 8 for proper re 7. JVA Synchronization, ExampleOn the actuator that is out of synchronization, flip thetoggle switch located on the bottom of the actuator tothe ON 2 position (see Figure 8). The toggle positionsare marked on the actuator top cover. Retry the system.Figure 9. JVA Mounting Positions.1.Turn OFF actuator power. Unscrewthe locking knob by turning the knobcounterclockwise. Remove the locking knoband valve handle.2.Remove the four (4) Phillips head screws thatsecure the actuator lid and then remove the lid.
Page 83.Jandy Pro Series Valve Actuator Installation and Operation ManualENGLISHImportant - Rotate the actuator shaft so thearrow mark on the top cam aligns with themicroswitch actuator (bottom cam arrow markshould also align with the bottom microswitchactuator, see Figure 10). Locate the mountingposition for the actuator (as per Figure 9, themounting position will be either I, II, III, or IV).Next, determine what valve port is the commonor inlet port (as per Figure 9, the common portwill be either A, B, or C). Then refer to theCam Setting Chart below to determine whatthe cam settings should be. For example, if theactuator is in JVA mounting position "I", and thecommon port on the valve is port "A", the camsettings would be 90 for the top cam and 180 for the bottom.NOTE The cam is marked with the arrow at "0", a long hashmark at the 180 position, and 2 short hash marks atthe 90 and 270 positions.4.To set the cams, rotate the cam(s) until thearrow mark on the cam(s) align with themicroswitch actuator (see Figure 11).NOTE The upper cam stops counterclockwise rotation andthe lower cam stops clockwise rotation.5.Turn power ON to the actuator and use thetoggle switch located on the bottom of theactuator to check rotation. Move the toggleswitch to either ON 1 or ON 2. Allow theactuator shaft to move until it stops. Checkvalve diverter position*, if the position iscorrect flip the toggle switch in the oppositedirection and allow the shaft to stop again. Ifthe stop positions are correct, go to step 6. Ifthey are not, reset the cams until correct.Final minor adjustments may be necessaryLowerCamUpperCamNOTE If the actuator does not move in either direction, referto Section 6, Troubleshooting.180 6.270 NOTE The end of the handle which has the word OFF90 00LeftMicroswitch0 Replace the lid and tighten screws.

Jandy Pro Series Valve Actuator Installation and Operation Manual5.3Rotate CamsFigure 11. JVA Cam AdjustmentManual OverrideIt is sometimes necessary to rotate valve(s) manually,without using the system controller. This occurs whenthe controller is not accessible/operational or when thespa or pool/spa combination require filling or draining.There are two (2) methods of manually rotating theJVA; one with power on (system operational) and onewith power off (no power to the control system).CAUTIONTo prevent damage to your equipment and tominimize the possibility of any injury resulting fromsuch damage, make sure that the pool filtration pumpis OFF BEFORE rotating the valve handle.5.2Manual Override, Power On1.Move the toggle switch located on the bottomof the actuator to the opposite position (ON 1switch to ON 2 or vice versa). This will rotatethe motor to the opposite position.2.Return the toggle switch to the original positionafter use.ON 1OFFOn/Off Switch ison Bottom of JVAON 2Figure 12. JVA Synchronization, TogglePage 9Manual Override, Power Off1.Move toggle switch located on the bottom ofactuator to the OFF (center) position.2.Unscrew (counterclockwise) the locking knobabove the handle four (4) full turns.3.Push down on the locking knob (not thehandle). This will disengage the gear train andallow the handle, and thus the valve diverter, tobe moved to any position.4.To return the actuator to automatic position, pullup on the handle while turning it clockwise orcounterclockwise until you feel the shaft slideup into the gear train. Turn the locking knobdown (clockwise) until snug.5.Put toggle switch back to the original position.Section 5. Manual Operation5.1ENGLISH
Page 10Jandy Pro Series Valve Actuator Installation and Operation ManualENGLISHSection 6. Maintenance6.16.2ValveNOTE This section does not apply to Jandy Pro SeriesActuatorThe JVA has three (3) seals which should be lubricatedonce a year. One o-ring is located on the bottom of theactuator where the plastic shaft exits the housing andtwo (2) O-rings located in the top cover near where theshaft exits the top of the housing. Use the followingsteps to lubricate the seals:1.Turn OFF power to the actuator.2.Remove the locking knob and handle(see Figure 13).Unscrew lockingknob and removehandleLubricate hereNever Lube Valves and non-positive seal valves.Never Lube Valves and non-positive seal valves canbe identified by the absence of a grease cap. NeverLube Valves can also be identified by the name"Never Lube" on the handle.Since the actuator rotates the valve diverter whichredirects the flow of water, it is imperative that the sealsand the O-rings within the valve body be lubricatedoften (at least every three (3) months). Use thefollowing procedure to lubricate the valve diverter seals:1.Turn off all pool/spa equipment.2.Rotate valve handle so the OFF on the handle isover the word GREASE on the valve body.3.Unscrew (counterclockwise) and remove theblack 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 thevalve.6.Use manual operation to move the handle fromside to side to spread the lubricant across theseal.7.Reset the valve handle to its original positionand start the equipment.Once a year the valve should be disassembled andthe O-ring and valve body inspected for damage.Thoroughly lubricate the square seal and the O-ring.Reassemble the valve.Figure 13. JVA Shaft Seal3.Spread a small amount of Jandy Pro SeriesLube or other silicone base lubricant around theactuator shaft just above the lock out ring (seeFigure 13).4.Reinstall handle and locking knob. Only tightenknob one (1) turn.5.Push down on the locking knob to force theactuator shaft into manual.6.Wipe a small amount of lubricant around theactuator shaft where it protrudes from thebottom of the actuator.7.Turn handle once around to spread the lubricant.8.Pull up on the handle and tighten locking knob.
