LIQUID LEVEL CONTROL
The system automatically maintains the hot water tank’s level by energizing the refill solenoid when the water level drops below the liquid level probe. If the system has not successfully refilled in 15 minutes, a refill error occurs. When a refill error occurs, the refill solenoid is
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 automatically 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.
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.
NOTE: Replacement parts or service caused by failure to perform required maintenance is not covered by warranty.

The beverage solenoid is preset to dispense approximately 9/10 ounce per second (26 mL/sec). This amount can be adjusted:
1.Disconnect the dispenser from the power source.
2.Remove the hoppers and the access panel behind the hoppers.
3.Rotate the control at the base of the solenoid clockwise to decrease or counterclockwise to increase the amount of water.
4.Replace access panel when finished.
HOPPER MOTOR SPEED PROGRAMING
NOTE: 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 is approximately 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, as follows:
1.Place the rinse/run switch in the center (program) position.
2.Hold the increase/decrease switch in the desired (increase or decrease) position.
3.While holding the increase/decrease switch, press and release the dispense switch for the chamber you wish to adjust. Each time the dispense switch is pressed, the rinse L.E.D. will flash, and the motor speed for that hopper will be increased/decreased by approximately 2 1/2%.
4.Return the rinse/run switch to the run position after hopper motor speed adjustments are complete.
5.Once any of the three hopper motors has been programmed to the desired speed, either or both of the other hopper motors can be set to the same speed as follows:
a.Place the rinse/run switch in the center (program) position.
b.Press and hold the dispense switch that has been programmed for the correct speed.
NOTE: Care must be taken not to exceed 5 seconds, or a hopper throw test will occur.
c.Momentarily press the dispense switch for the hopper motor to be programmed. The rinse L.E.D. will light for approximately 1 second, indicating that the speeds have been set equal.
d.Release both dispense switches.
e.Repeat step 5. b. through 5. d. for remaining hopper motor if desired.
f.Return the rinse/run switch to the run position after hopper motor speed adjustments are complete.
DRAINING THE HOT WATER TANK
CAUTION - The dispenser must be disconnected from the power source throughout these steps.
1.Disconnect the dispenser from the power source.
2.Place the tank heater switch in the “OFF” position.
4.Remove the front, lower access panel.
5.Pull out drain tube to empty into a sink or a container with a minimum of
6.Make sure drain clamp is closed. Then, remove drain plug.
7.Direct tube into sink or container and open drain clamp. Continue draining tank until ALL of the water is out.
WARNING: Be very careful with the draining water because it can be very hot.
8. Close drain clamp, insert drain plug, place drain tube back into machine, and replace lower access panel. NOTE - The dispenser must be refilled using theINITIAL FILL & HEAT steps before reconnecting to the power source.
