INITIAL FILL & HEAT
1. Turn on the water supply and connect the dispenser to the power source.
2. Water will automatically flow into the tank to the proper level and then shut-off. This will take less than ten
minutes.
3. A tank full of cold water will take approximately fifty minutes for the water to heat at 120 volts, approximately
15 minutes at 240 volts.
4. Fill the hoppers with the dry product to be dispensed. Hot chocolate in the left hopper, powder milk product
in the right hopper.
5. The LED display on the control panel behind the door splash panel will alternately display the tank water
temperature and the cold shoe temperature.
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 de-energized. Once the cause of the refill error has been
investigated and cured, the system can be reset by both disconnecting (for at least 5 seconds) and then recon-
necting the power to the machine.
RINSE ALARM FEATURE
Periodic rinsing of the mix chambers and dispense tips is essential for proper maintenance and optimum per-
formance of the dispenser. The dispenser is shipped from the factory with the rinse timer enabled.
The rinse timer automatically keeps 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 the desired time, all LEDs’ on the membrane
switch on the front door will flash, and "RINSE" will be displayed on the LED display behind the door splash
panel.
Rinse Procedure:
1. Open the front door and place the Normal/Program/Rinse switch in the RINSE position.
2. Place a large container under the dispense nozzle. Press any dispense button on the front door. The LED
display above the programming buttons will begin counting down from 8. The rinse will terminate when the
display reaches “0”.
3. Return the Normal/Program/Rinse switch to the NORMAL position, and close the front door.
EMPTY PRODUCT WARNING
The dispenser will automatically illuminate the LED next to the Decaf or Hot Chocolate button when the Decaf
or Regular coffee BIB is empty, respectively. The Refill message is triggered when conductance sensor reading
drops below the minimum setting. The factory set minimum is 450 and should be correct for many locations.
However, in some areas the hardness of the local water supply will affect this reading. It is recommended that
the Empty Product Threshold be calibrated upon installation for proper operation of the Empty Product Warning.
See "Field Calibrating the Empty Product Warning" in the Calibration section of this manual.
