RINSE TIMERS

The dispenser is shipped from the factory with the rinse timers disabled. To enable the rinse timers, remove power from the dispenser, remove the lower access panel, and remove the jumper from J1 of the control boards. Replace the lower access panel, and return power to the dispenser. When enabled, the rinse timers automati- cally keep track of the time since the dispenser was last run through a rinse sequence. If the dispenser detects that a rinse sequence has not been run for 8 hours, the appropriate rinse L.E.D. will flash continually. If, after an additional 4 hours (12 hours total), a rinse sequence has still not been run, the appropriate rinse L.E.D. will light continuously, and the appropriate hopper drives will be disabled until a rinse sequence has been run.

RUNNING A RINSE SEQUENCE

1.Place the rinse/run switch in the rinse position.

2.Sequentially, or simultaneously, at each of the positions dispense for at least 10 seconds.

3.After the rinse L.E.D. has extinguished, the rinse timer is reset.

4.Return the rinse/run switch to the run position.

DISPENSER USE

1.Simply place a cup on the drip tray beneath the dispensing tip.

2.Press the button and dispense the beverage.

3.Release the button when the cup is approximately 3/4 full and allow the whipper chamber to drain.

NOTE - The whipper chamber must drain at the end of each dispense.

HOPPER THROW TEST

The hopper throw rate, grams per second (g/s) or ounces per second (oz./s), can be checked by automatically running the hopper motor for 10 seconds.

1.Remove the steam collector and mixing chamber from under the hopper to be checked.

2.Position a small cup under the hopper outlet.

3.Place the rinse/run switch in the center (program) position.

4.Press and hold the dispense switch of the appropriate chamber for 5 seconds. The hopper motor will run for 10 seconds at the programmed speed.

5.Remove the cup and weigh the dispensed product. To calculate the throw rate (g/s or oz./s), divide the total weight of the dispensed product by 10.

6.Replace the mixing chamber and steam collector, and return the rinse/run switch to the run position.
