DISPENSER USE
1. Simply place a cup on the drip tray beneath the desired dispensing tip.
2. a) Momentarily press the appropriate dispense switch to froth and dispense the beverage. The dispenser will
automatically dispense the beverage for the programmed dispense time at the programmed hopper dispense
rate. The dispenser is factory preset to produce the approximate dispense sizes as follows:
Small (8 seconds): approximately 8 fluid ounces of beverage.
Medium (12 seconds): approximately 12 fluid ounces of beverage.
Large (16 seconds): approximately 16 fluid ounces of beverage.
To stop a timed dispense, press the stop switch or any of the switches on the position that is running.
Note - The mixing chamber must drain at the end of each dispense.
The dispense times can be individually programmed by following the procedures described in Programming
Modes.
b) Hot Water - Push and hold the hot water switch until the water reaches the desired level, then release.
HOPPER DISPENSE RATE OF PRODUCT
The hopper dispense rates are preset at the factory. With 22 tooth gear and auger wire, the preset dispense rate
is approximately 3 to 5 grams per second. With 30 tooth gear and auger wire, the preset dispense rate is approxi-
mately 5 to 7 grams per second. The hopper dispense rates can be individually programmed to a range of
dispense rates from approximately 1.5 to 12 grams per second by following the procedures described in Pro-
gramming Modes.
PROGRAMMING MODES
1. Enter / Exit:
a. To enter the program mode, press any two dispense size switches, on the position to be programmed, at the
same time. The L.E.D. will flash indicating the program mode.
b. To exit the program mode, press a switch on any position other than the one being programmed.
Note: The stop switch will not cause exit of program mode since it is used for some programming operations.
If in the program mode for more than 25 seconds and no switches have been pressed, the program mode is
automatically exited.
2. Dispense Run Time:
a. Enter the program mode on the position you want to program (see step 1.a.)
b. Place the "Rinse/Run" switch in the "Run" position and press and hold the cup size to be programmed.
c. When the desired amount is reached, release the switch, the time is recorded in memory.
To set the time to non-timed dispense, just momentarily press the position switch. This actually sets in a very
short timed dispense.
d. Repeat for remaining cup sizes if desired.
e. Exit the programming mode (see step 1.b.)
3. Increasing / Decreasing the Hopper Dispense Rate:
a. Enter the program mode on the position you want to program (see step 1.a.)
b. Place the Rinse/Run switch in the "Rinse" position.
c. Press and hold down on the stop switch and press the small switch to decrease the dispense rate or press
the large switch to increase the dispense rate. Each time the button is pressed, the dispense rate will increase/
decrease by approximately 2
will flash on and off to indicate the switch was recognized. When the maximum or minimum level is reached
