NEEDLE VALVE ADJUSTMENT (Models with Faucet)

This brewer is equipped with a unique faucet system allowing hot water to be drawn-off a cup-at-a-time for

instant beverage needs, even while brewing.

WARNING - Disconnect the brewer from the power source before the removal of any panel or replacement of

any component.

ADJUSTMENT

1. Disconnect the brewer from the power source and remove the front inspection panel located beneath the

brew funnel.

2. Adjust the needle valve as required to increase or decrease the pressure of the hot water ﬂowing from the

faucet. Turn the propeller on the valve in a counterclockwise direction to increase the ﬂow and in a clockwise

direction to decrease the ﬂow.

3. Reconnect the brewer to the power source and allow the water in the tank to heat to the proper temperature

before operating the brewer.

CLEANING

1. 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.

2. Check and clean the sprayhead. The sprayhead holes must always remain open.

3. With the sprayhead removed, insert the deliming spring (provided) all the way into the sprayhead tube. When

inserted properly, no more than two inches of spring should be visible. Saw back and forth ﬁve or six times.

Then, repeat this step for the air vent tube.

NOTE - In hard water areas, this may need to be done daily. It will help prevent liming problems in the brewer

and takes less than a minute.
