INITIAL FILL & HEAT

CAUTION - The dispenser must be disconnected from the power source throughout the initial set-up, 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 or twenty minutes for 120/208 volt versions and 120/240 volt versions.

During this waiting period, complete these dispenser set-up steps:

a.Place the drip tray in front of the dispenser. Set the drip tray cover in place.

b.Place a set of keyholes in the cup locator plate over the screws beneath the hopper access door and push down gently.

c.Fill the hopper with the dry product to be dispensed.

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 for the FMD-2 only 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 in the Operating and Service Manual) and cured, the system can be reset by disconnecting (for at least 5 seconds) and then reconnecting the power to the machine.

RINSE TIMER (FMD-2 ONLY)

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 two positions (FMD-2 only) dispense for at least 10 seconds.

3.After the rinse L.E.D. has extinguished, the rinse timer is reset (FMD-2 only).

4.Return the rinse/run switch to the run position.

DISPENSER USE

1.Simply place a cup on the drip tray beneath the dispensing tip.

2.Press the button to froth and dispense the beverage.

3.Release the button when the cup is approximately 2/3 full and allow the mixing chamber to drain.

NOTE - The mixing chamber must drain at the end of each dispense.
