SETTING DISPENSER FLOW RATE
The dispenser comes from the factory with flow restrictors in the mix chambers. With the restrictors in place
the dispense rate is about 1.8 oz./sec (53.2 ml/sec) and is used primarily for cup at a time dispensing. The
flow restrictors can be removed to increase the dispense rate to about 2.5 oz./sec (74 ml/sec) for larger volume
dispensing (airpots, carafes, etc.).
NOTE: The hot water FlowRate is fixed at approximately 1.7 oz/sec. and can not be adjusted.
Removing the restrictors:
1. Disconnect the dispenser from the AC power source.
2. Open the Product Cabinet door.
3. Remove the concentrate tube, vent line and grommet from mix chamber ports in side the product cabinet.
4. Remove the two screws that fasten mix chamber to the control panel.
5. Gently pull mix chamber away from dispenser to expose water line connection, (you may have to rotate it
slightly).
6. Disconnect FlavorGard™ sensor wire and hot water tubing from the mix chamber.
7. Remove the flow restrictor from the inlet to the mix chamber.
8. Reconnect FlavorGard™ sensor wire and hot water tubing to the mix chamber.
9. Place mix chamber back into position in the dispenser, (you may have to rotate it slightly) and secure it with
the two screws
10. Reposition the grommet, vent line and pump tubing onto the mix chamber ports.
Caution: Failure to properly replace and secure any of the above components may result leaks and/or cause
damage to the dispenser.
If you changed the Dispenser Flow Rate, you will need to reprogram the dispenser to the new rate, see Programming
the Dispenser.
CAUTION: Failure to reprogram the Dispenser Flow Rates will result in inaccurate Mix Ratios.
Reprogramming the Dispenser Flow Rate:
1. Remove the lower splash guard panel and locate the Programming module.
2. Use the Down Arrow key to enter into the programming function and scroll through the menu’s to the “CAL
LEFT SIDE?” menu and select “YES”.
3. Scroll down to the “CAL LF WTR VOL” menu
4. Use the (+) & (-) keys to enter a volume of 50 Oz. (1478 mL). This will recalibrate the Left dispenser to the
new rate.
5. Scroll down to the “CAL RT WTR VOL” menu
6. Use the (+) & (-) keys to enter a volume of 50 Oz. (1478 mL). This will recalibrate the Right dispenser to the
new rate.
7. Select “Exit” to leave the programming menu.
Note: The default volume of 50 Oz (1478 mL), is the typical Cal Volume for a 2.5 Oz/sec Flow Rate Test, see Field
Calibration of the Concentrate Pumps / Dispenser Flow Rates.
