PLUMBING HOOK-UP

1.Securely attach the short piece of tubing on the water strainer assembly to the inlet fitting on the bottom of the dispenser.

2.Flush the water line and securely attach it to the flare fitting on the water strainer assembly.

3.Turn-on the water supply.

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, and twenty minutes on 120/240 and 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(s) with the dry product to be dispensed.

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 2/3 full and allow the mixing chamber to drain.

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

COLD BEVERAGE SET-UP (OPTIONAL)

Cold beverages may be dispensed from the left dispense position on the HC-2 & HC-3 models. Simply place the HOT/COLD switch near the left whipper chamber in the “COLD” (upper) position.

CLEANING

Refer to the decal inside the hopper access door for cleaning recommendations and procedures.

The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment.

ADJUSTMENTS

The hot or cold beverage solenoid(s) is (are) preset to dispense approximately one ounce per second. This amount can be adjusted:

1.Disconnect the dispenser from the power source.

2.Remove the small right side access panel.

3.Rotate the control at the base of the desired solenoid(s) clockwise to decrease or counterclockwise to increase the amount of water.

4.For cold beverage adjustment remove the 1-1/2” plug on the lower left side of the dispenser and rotate the needle valve clockwise to decrease or counterclockwise to increase the amount of cold water.
