INSTALLATIONINSTRUCTIONS 424 AND324 POST-MIX VALVES

The Flomatic 424 and 324 valves are available inmanual, electric, portion control and automatic fillmodels. All Flomatic 424 and 324 valves share thesame mounting and flow control characteristics. The324 valves are also compatible with the 300-Q mount-ing block. Those instructions are not included here.

MOUNTING BLMOUNTING BLMOUNTING BLMOUNTING BLMOUNTING BLOCKOCKOCKOCKOCKPrior to installation determine which mounting blockyou need. The Flomatic mounting block kit 380Q-372 has inlet “O” rings sized for both inlet port sizes(located at the rear of the block) port. Sized at 0.380inches is compatible with most current mountingblock inlet fittings.

When replacing most other brandvalves with the Flomatic valve, remove the existingmounting block and install the appropriate Flomaticmounting block. This is an easy first step – just alignthe four bolt holes and mount. The Flomatic mount-ing blocks have a positive shut off and mountingsystem to prevent accidental removal while the sys-tem is pressurized. The valve cannot be removedunless the shut-off valves are in the closed position(arrows pointed across the service line).

The hole pattern for most current valves will havekey slots for the product supply lines. Some oldervalve mountings may require the use of the “S” clip

to hold the product supply lines in place (availableas an option).

Remove the valve coverand align the valve stemswith the mounting block.Engage the valve anddepress the latch pin. Donot force the latch pindown or you may bendthe latch pin. If you arehaving difficulty, simplyre-engage the valve andtry again. Be sure thevalve base is completelyseated against themounting block. Openthe shut-off valves by turning 1/4 turn (arrows pointedtoward the service line) to engage system pressure.

FLFLFLFLFLOOOOOW CONTRW CONTRW CONTRW CONTRW CONTROL OL OL OL OL AND BRIXAND BRIXAND BRIXAND BRIXAND BRIXTwo simple adjustments are all you need to brix theFlomatic valves. You will need a Flomatic S tubesyrup separator, 5/32 inch hex wrench, watch andbrix cup. Place the S-tube syrup separator over thesyrup diffuser and you are ready to begin. You neednot remove the nozzle.

Clockwise movement of the brix nut adjustmentscrew increases the flow rate and vice versa. Re-strict the flow by withdrawing the brix nut adjust-ment screw as far as it will go (turn counterclock-wise). At this point the flow will be at a minimum.

The 424 or 324 ceramicflow controls can be ad-justed from 1.5 oz. /sec.to 3.0 oz. /sec. Turn thesoda brix nut adjust-ment screw five fullturns clockwise and theflow rate should beclose to 2.5 oz/sec. Youwill need to fine tunefrom there. For fast flow,continue adjusting thevalve until you get 7.5ozs. of soda in 3 sec-onds. Once the sodaflow rate is set, then establish the syrup ratio (nor-mally 5:1) in exactly the same way.

Most brix cups are calibrated for the standard 5:1ratio. Adjust the syrup flow with movement of theadjusting screw until the desired ratio is established.

Some Flomatic valves are equipped with a flowwasher on the water side instead of flow controls.In that case, it is not necessary to set the flow rate.Simply set the syrup ratio and you are done.

Flomatic juice valves may combine with a flowwasher on the water side. The syrup side may bemanufactured with a flow control or metering screw.The metering screw turns clockwise to close andcounter clockwise to open. The screw does nothave a stop; be sure not to withdraw completelywhen under pressure.

SYNCHRSYNCHRSYNCHRSYNCHRSYNCHRONIZAONIZAONIZAONIZAONIZATIONTIONTIONTIONTIONWhen converting a manual 424 to electric solenoidoperation, the actuators need to be removed prior toinstalling the yoked armature solenoid coil. The actua-tors are the white pivots that engage the pallet stem.

Synchronization should only be necessary whenconverting an electric to manual valve, in which caseyou may be adding the actuators. The soda adjust-ment screw needs to be adjusted until it is snug (nottight). If too tight, the valve will remain open and leak.Set the soda side first and then follow with the syrupactuator. The syrup actuator needs to be tighteneduntil snug and then backed off 1/4 turn. These set-tings will allow for proper synchronization of the sodaand syrup on a manual valve.

If youhave the pallet actuators as described above, simplyremove the valve cover and place the Add-A-Lever(with the side attachment removed) on the end of thepivot pin. Replace the cover and it will be firmly heldin place to provide soda only when desired. If youhave the electric operated valve without the actua-tors, the side attachment of the Add-A-Lever is placedthrough the pivot pin to push against the pallet stem.The lever portion of the Add-A-Lever is placed on theend of the pivot pin. Replace the valve cover and theAdd-A-Lever will be held in place.

stalled. When installing in the field, simply order theportion control conversion kit to upgrade an electricvalve to full portion control.

The portion control module is designed to simplifyinstallation for the service technician. No more wastedproduct trying to set the time though trial and error.The board can be programmed with the first pour.

The “Stop/Fill” button does just that; it serves as atop-off button and cancels any of the timed portions ifthe operator needs to abort the pour. If the board hasnever been programmed, the only button that will beresponsive is the “Stop/Fill” button. Cup sizes arepreprogrammed at the factory: 1 sec. = small, 2 sec.= medium, 3 sec. = large, 4 sec. = extra large. Thesetimed portions are helpful in setting flow rate; i.e., 7 ½ozs. soda in 3 seconds.

There are four cup sizes: small, medium, large andextra large. Each cup size needs to be programmedseparately. Set the flow rate first and then brix thevalve. By doing so, you will be sure to set times thatmatch your desired flow rate. Once the valve is brixed,you can replace the valve cover because the times(cup sizes) are all set fromthe front switch pad.

The switch pad has a hidden“program” switch whichneeds to be held down tokeep the module in programmode. Setting the times orprogramming is a twohanded operation: push and

hold the program switch with one finger while dispens-ing the cup size you wish to program with another.Once the drink is full, simply release the cup size but-ton to end the pour cycle and then let go of the pro-gram switch. Repeat the process for each cup sizeand you are finished.

The module will remember onetop-off cycle automatically if thefoam height requires a top-off tocomplete the pour. To program atop-off cycle, simply begin pro-gramming as described above.Once the foam crests the top ofthe cup, PAUSE by removing yourfinger from the cup size button. Donot release the program button orit will think you’re done. Pause longenough for the foam to settle, andthen continue your pour with yourfinger on the same cup size but-ton until the cup is full. The por-tion control module will rememberthe sequence “pour – pause –pour” just as it was executed.

If you program the top-off feature, be sure to trainthe operators so they do not pull a drink before thecycle is complete. The portion control module willfinish the pour whether a cup is there or not.

CLEANINGCLEANINGCLEANINGCLEANINGCLEANINGUnder normal operating conditions, periodic clean-ing is minimal but necessary. Remove the nozzle andsoda diffuser. Using warm water and a mild deter-gent, clean each part with a brush. Once finished,rinse well and reassemble. If you wish to soak thenozzle and diffusers, soak them only is soda water,never use bleach. Brush lever slot with warm waterto prevent syrup build-up and sticking. Wipe coverand panel with a clean cloth and you are finished.Nothing more need be done unless you experienceda problem. Regular servicing and cleaning of thecomplete beverage system is advised to maintainproper functioning of the equipment. Be sure to fol-low instructions provided by the manufacturer.

TRTRTRTRTROUBLE SHOOOUBLE SHOOOUBLE SHOOOUBLE SHOOOUBLE SHOOTINGTINGTINGTINGTINGOccasionally, the valve will not perform as desired.Here are some helpful hints:

BRIX: Reset the flow rate and re-brix the valve. Lookfor foreign matter in the adjustment screws, flowcontrols or pallet seats. Sometimes if a system isnot flushed completely at startup, foreign particles,etc. will be introduced into the system.

BUZZING: Make sure the plungers in the older style doublecoil solenoid are properly aligned. Do not lubri-cate the plungers with anything other than a “dry”product, e.g., silicone spray.

LEAKS: Check for damaged or improperly fitted O-rings.The slightest piece of hair, dust, etc., on thesealing surface may contribute to a leak. Whenin doubt, replace an O-ring. Be sure you havethe correct O-ring and fitting combination for therespective mounting block.
