COFFEE BREWING

3.Slide the funnel into the funnel rails.

4.Place an empty dispenser beneath the funnel.

5.Operate the brewer as directed:

5A.Models CW-APS & CW-TS:

5B.Models CWT-APS, CWTF-APS, CWT-TS, CWTF-TS, CWT-TSR & CWTF-TSR

Place the "ON/OFF" switch in the "ON" (upper) position. Momentarily press and release the start switch.

6.When brewing is completed, simply discard the grounds and filter.

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.

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.
