OPERATING THE DISPENSER

The Cabinet door must be closed & latched and the Function Selector Switch set to RUN to dispense coffee.

To Dispense Coffee

1.Select the desired volume (1, 2 or 3) using the rotary switch.

2.Place the appropriate container under the dispense tip.

3.Press and release the desired flavor switch to dispense product. The LCD will display “DISPENSING PRODUCT” “PRESS ANY SWITCH TO STOP”. Note: Pressing any switch after starting a dispense cycle - will abort that dispense and halt the flow of product.

4.Remove the container and serve accordingly.

To Dispense Hot Water

1.Place container under the hot water dispenser tip.

2.Pull and Hold the Hot Water handle until the water reaches the desired level, then release.

3.Remove the container.

NOTE: For large containers that will not fit under the dispense tip, a short 3/8” diameter NSF approved hose may be used.

FILLING CAMBROS OR OTHER LARGE CONTAINERS

The dispenser is designed primarily for containers that will fit under the dispense tip. However, it may be used to fill larger containers (up to 5 Gal) by use of an extension hose on the dispense tip. Care must be taken to insure that the mixed product flows freely from the dispense tip into the container.

1.Use a 5/8” I.D. or larger, NSF (National Sanitation Foundation) approved hose.

2.Use as short a hose as possible with no loops, bends or kinks in it.

3.Insure that the outlet of the hose is below the dispense tip and that the mixed product flows freely into the container.

4.A properly sized and positioned hose will not run full or back up into the dispense tip. Failure to follow these directions can alter the mix ratio and/or cause flooding of the vent tube.

NOTE: Recovery time will be dependent on the temperature of the supply water and the supply voltage to the dispenser.
