INITIAL FILL & HEAT
CAUTION - The dispenser must be disconnected from the power source throughout the initial fill & heat, except
when specified in the instructions.
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 five
minutes.
3. When the tank is full of water, open the front door and place the heater switch in the ON (lower) position.
A tank full of cold water will take approximately forty minutes for the water to heat on 120 volt versions, and
twenty minutes on 120/240 volt versions.
During this waiting period, complete these dispenser set-up steps:
a. Place a set of keyholes in the splash panel over the screws beneath the hopper access door and push down
gently.
b.Place the drip tray onto the supports on the splash panel. Hook the tabs on the rear of the drip tray through
the holes in the splash panel. Set the drip tray cover in place.
c. Fill the hopper(s) with the dry product to be dispensed.
LIQUID LEVEL CONTROL
The system automatically maintains the hot water tanks level by energizing the refill solenoid when the water level
drops below the liquid level probe. If the system has not successfully refilled in 7 1/2 minutes, a refill error occurs.
When a refill error occurs, the refill solenoid is de-energized and the rinse L.E.D. will flash about once every 5
seconds.
Once the cause of the refill error has been investigated (see the troubleshooting guide) and cured, the system can
be reset by disconnecting (for at least 5 seconds) and then reconnecting the power to the machine.
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 J1 of the control
board. 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, the 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 rinse
L.E.D. 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 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 desired dispensing tip.
2. Press the button to froth and dispense the beverage.
3. Release the button when the cup is approximately

full and allow the mixing chamber to drain.
NOTE - The mixing chamber must drain at the end of each dispense.
