OPERATING CONTROLS
Models S & SA:
These models function without operating controls.
Models ST, STF, STA & STFA:
ON/OFF SWITCH
Placing the "ON/OFF" switch in the "OFF" lower position stops brewing. Stopping a brew cycle after it has been
started will not stop the flow of water into the funnel until the tank syphons down to its proper level. Placing the
switch in the "ON" upper position supplies power to the brew station warmer and enables the brew circuit and on
Models STF and STFA refills the tank.
START SWITCH
Momentarily pressing and releasing the switch starts a brew cycle when the "ON/OFF" switch is in the "ON" upper
position.
NOTE – The "ON/OFF" switch must be in the "ON" upper position to initiate and complete a brew cycle.
COFFEE BREWING
1. Insert a BUNN
®
filter into the funnel.
2. Pour the fresh coffee into the filter and level the bed of grounds by gently shaking.
3. Slide the funnel into the funnel rails.
4. Place an empty dispenser beneath the funnel.
5. Operate the brewer as directed:
5A. Models S & SA:
Pour one pitcher of tap water into the screened area on top of the brewer.
5B. Models ST, STF, STA & STFA:
Place the "ON/OFF" switch in the "ON" upper position. Momentarily press and release the start switch.

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.
