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.

CLEANING

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).

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.

FILTER HOLDER

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.
