To increase a batch size. Press and hold the START or BREW switch until three clicks are heard. Release
the switch (Failure to release the switch within two seconds after the third click causes the volume setting to
be aborted and previous volume setting will remain in memory) and press it again one or more times. Each
time the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in
order to verify that the desired volume has been achieved.

to be removed from the total brew time period; then immediately press and hold down the START or BREW
switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after
the third click causes the volume setting to be aborted and previous volume setting will remain in memory).

OPERATING CONTROLS
Model C
ON/OFF SWITCH
Placing the "ON/OFF" switch in the "ON" upper position supplies power to the brew station warmer.
Models CT, CTF, CWT, CWTA, CWTB, CWTF, CWTFA, CWTFB, SINGLE CW & SINGLE CWF
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.
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. Model C
Pour one pitcher of tap water into the screened area on top of the brewer.
5B. Models CT, CTF, CWT, CWTA, CWTB, CWTF, CWTFA, CWTFB, SINGLE CW & SINGLE CWF
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.
