Coffee Brewing & Cleaning - Bunn U3 Installation And Operating Manual

1. Brewing cycles may be started whenever water temperature is correct. This condition is indicated by the dial
thermometer on front of the brewer. Whenever the pointer is in the green, brewer is ready for brewing.
2. Insert Bunn filter in funnel and add desired amount of coffee.

3. Level the bed of coffee and place funnel into the funnel support. Place funnel cover over the funnel and be
sure the water swing spout is over the center of the funnel cover.
4. Turn "ON/OFF" switch to the "ON" position.
5. Push and release "START" switch to start the brew cycle.
6. Water swing spout should not be moved as long as water is flowing into the funnel cover. When water stops
flowing, it may then be moved for access to brewing funnel.
7. Remove funnel cover. Funnel should not be removed from brewer until drip out of coffee has been com-
pleted.
8. To empty funnel, invert it over a waste container to dispose of filter and grounds. An additional flange is
provided on the funnel to help make this step easier.
NOTE: Hot water may be drawn from the hot water faucet during a brew cycle. However, if a large amount of
hot water is drawn off (over 1 gallon) operator should wait to do so between brewing cycles.
NOTE: Tanks and tank components should be delimed regularly based on local water conditions. Excessive
mineral build-up on stainless steel surfaces can initiate corrosion reactions resulting in serious leaks.
1. Remove funnel(s), funnel lid(s) and support(s), under hot water, rinse away all coffee oils. Wipe with a clean
damp cloth.
2. Drain coffee reservoir(s) by opening coffee faucet(s). When empty, close faucet(s).
3. Cycle two or three inches of water into coffee reservoir(s) and scrub entire reservoir area.
NOTE: The brewer must NOT be rinsed or cleaned by a water jet device.
4. Drain coffee reservoir(s) and rinse. Use clean damp cloth to wipe reservoir(s).
5. Install coffee funnel supports, funnel(s) and funnel lid(s).
6. Remove the sight gauge cap, insert sight gauge cleaning brush into the sight gauge glass tube and clean.
7. To clean coffee faucet(s), remove the faucet handle from the faucet and faucet clean out cap. Clean faucet
with a faucet cleaning brush and wipe all parts with a damp cloth. Replace faucet seat cups periodically if
badly stained or to stop faucet dripping. DO NOT CLEAN THE HOT WATER FAUCET.
8 Reassemble the coffee faucet(s).
9. Wipe the entire outside surface of the machine with a clean damp cloth. Wipe dry.
1. A filter holder is supplied with each brewer. Its purpose is to keep the filters in their originally formed shape
to properly fit the brewer funnel.
2. It is suggested that only one cluster of filters be placed in the holder at one time for best results.
3. Not using the filter holder may permit the filters to gradually widen out towards a flat shape, especially so if
humidity is present. Once a filter has lost its upright side walls, it may tend to collapse inward when placed
in the brewing funnel. If this happens the hot water spray may cause one side to fall inwards, letting coffee
grounds flow over the edge of filter and into the brewed coffee. Proper use of the holder should prevent this
problem.
