Instructions for Proper Dispensing Valve
Calibration (Flow, Ratio, and Volume)
usingthe4-Size Portion Control
Flow (to set the water flow rate only)
Check that the Primary CO
2 tank high
pressure regulator or bulk CO
2 regulator is
adjusted properly. The Medium pressure
regulator for sugar-based syrup must be adjusted
to 60 psi (4 bar). The Low pressure regulator for
sugar-free syrup must be adjusted to 14-16 psi
(0.9-1.1 bar).
1. Turn off the syrup at the dispensing valve
by turning the syrup shut-off (located on the
valve mounting block). If there is no syrup
shut-off, use a syrup separator.
2. Check the water shut-off (if applicable). It
should be in the full open position.
Note: The syrup and water shut-off (if
equipped) are not to be used as an alternate for
flow controls. They are to be used only for shutting
on or off the syrup and/or the water supply.
3. Place a volume cup with 10 oz. (295.7 mL)
measurement line, under valve to be adjusted.
If using syrup separator, place volume cup un-
der water side of separator only.
4. Use 4-Size portion control timer to obtain an
accurate 4 second pour as follows:
a. Press CAL pad three (3) times in less than
3 seconds to enter calibrate mode. Cali-
brate lamp will light. (Omit this step if
already in calibrate mode).
b. Press STOP-FILL pad of valve to adjusted
once to cause 4 second pour into volume
cup.
Note: Fast-fill valves will dispense 10 oz in 4 sec-
onds and standard-fill valves will dispense 5 oz in
4 seconds. Diet and other products with high foam-
ing tendencies would be adjusted to 7.6 oz and
3.8 oz respectively.
5. To adjust the water flow rate (if necessary),
turn the adjusting screw clockwise to increase
and counterclockwise to decrease the flow of
water.
6. Repeat 4 second dispense (STOP-FILL pad) and
water flow adjustment, until volume is cor-
rect.
7. Open syrup shut-off or remove syrup separa-
tor (if applicable).
8. Repeat this procedure (steps 1 through 7
above) for each valve.
9. Press CAL button once to exit calibrate mode.
Calibrate lamp will go off.
Ratio (water to syrup mixture)
1. Remove valve nozzle by turning the nozzle and
pulling down.
2. Place syrup separator on valve to be adjusted.
Actuate the valve manually (pad, lever) until
both syrup and water flow out of the syrup/
water separator.
3. Position the proper ratio cup under the syrup
separator. Manually actuate the valve pad or
lever valve (pad, lever). Dispense until at least
3
/4 of the ratio cup is filled. Both products
should fill to the same level.
4. To adjust the syrup flow (if levels are not
equal), turn the syrup flow control adjusting
screw clockwise to increase and counter-
clockwise to decrease the flow of syrup.
Note: Do not adjust the water flow during this
procedure.
5. After syrup is adjusted, remove the syrup sepa-
rator and replace the valve nozzle.
6. Repeat this procedure (steps 1 through 5
above) for the remaining valves.
Volume (setting drink portion sizes)
1. To enter portion control calibrate mode, press
CAL pad three (3) times in less than 3 sec-
onds. Calibrate lamp will light.
2. Use volume cup with finished drink marking
lines, or use correct size sample cup with de-
sired volume of ice.
3. Press and hold respective SIZE pad until prod-
uct gets close to proper finished drink mark,
or until close to top of sample cup.
4. Release SIZE pad before reaching final mark
or before foam exceeds final mark. Press SIZE
pad again momentarily, as many times as is
necessary (letting foam settle), to get to the
correct finished drink mark.
5. Repeat steps 2 through 4 above for all sizes
and all stations (products) needing calibration.
Be sure to use the correct volume cup fin-
ished drink marking line, or correct sample
cup size and ice amount, for each size pad.
Note: If you fill above the final mark or need to
"start over" for any reason, you must exit the cali-
brate mode and then re-enter the calibrate mode
to resume.
6. Exit calibrate mode by pressing CAL pad once.
Calibrate light will go out. All changes will be
permanently saved.
