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 and the 3 position L.E.D.’s will flash sequentially;
left...center...right...left...center...right...etc.
Once the cause of the refill error has been investigated (see the troubleshooting guide) and cured, the system
can be reset by either disconnecting (for at least 5 seconds) and then reconnecting the power to the machine,
or by entering one of the program modes (see Programming Modes.)
RINSE TIMER
The dispenser is shipped from the factory with the rinse timer disabled. To enable the rinse timer, remove power
from the dispenser, remove the lower access panel, and remove the jumper from J4 of the control board. For
dispensers with hot water dispense, remove power from the dispenser, remove the lower access panel, and dis-
connect the green wires coming from J4 of the control board from each other. Replace the lower access panel,
and return power to the dispenser.
When 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 8 hours, all three position
L.E.D.’s will flash continually. If, after an additional 4 hours (12 hours total), a rinse cycle has still not been run,
all three position L.E.D.’s will light continuously, and the 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 three positions, press any of the three dispense switches. The
dispenser will run for 10 seconds with the hopper(s) disabled.
3. As each position is rinsed, the corresponding L.E.D. will extinguish, indicating that the rinse cycle took
place.
4. After all three position L.E.D.’s have extinguished, the rinse timer is reset.
5. Return the Rinse/Run switch to the “run” position.
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.
