INITIAL SET-UP (cont.)
4. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature.
5. Place an empty server beneath either of the brew stations. Place its associated Selector switch in the desired
position, the On/Off switch in the upper position and initiate a brew cycle.
6. Place the On/Off switch in the lower OFF position after water has stopped flowing from the funnel, and check
the water volume in the server. It should be 64 oz (1/2 gallon), 128 oz (1 gallon), 224 oz (1-3/4 gallon) or adjust
volume to your company specifications. On models with Digital Timers, refer to
Service
section for
adjustments.
NOTE: Brewer will not operate if the server size does not match the selected batch size.
7. (A) If not, disconnect the brewer from the power source, remove the front panel, and adjust the brew timer for
that brew station as required. Replace the front panel, connect the brewer to the power source, allow the water
to reheat, start, and measure another brew cycle.
(B) If necessary adjust the needle valve to achieve desired water volume to be bypassed around the coffee filter
in the funnel.
NOTE: To increase the water bypass turn the needle valve counterclockwise, to decrease the water bypass turn
the needle valve clockwise. An adjustment of the needle valve will require a timer adjustment for volume of 1
gallon and 1-3/4 gallon.
8. Repeat step 7 until the proper water volume is achieved.
9. Repeat steps 5 through 8 for the other brew station.
10. The brewer is now ready for use in accordance with the coffee brewing instructions.
OPERATING CONTROLS
BREW SELECTOR SWITCH
Placing the switch in the
1
2 Gal, 1 Gal, or 1-
3
4 Gal position selects the amount of coffee to be brewed in
subsequent brew cycles. Repositioning this switch after a brew cycle has been initiated does not change the brew
batch in progress.
ON/OFF SWITCH
Placing the switch in the unlighted lower position cuts power to the server sensor and stops brewing. Stopping
a brew cycle after it has been started will not stop the flow of water from the funnel. Placing the switch in the lighted
upper position supplies power to the server sensor and enables the brew circuit.
START SWITCH
Momentarily pressing and releasing this switch starts a brew cycle when the On/Off switch is in the lighted
upper position.
GRINDER SELECTOR SWITCH
Pressing the right or left side of the switch selects the corresponding brew station to the grinder interface.
NOTE – The On/Off switch must be in the lighted upper position to initiate and complete a brew cycle.
COFFEE BREWING

2. Insert a BUNN
®
filter into the funnel.
3. Pour the proper amount of fresh ground coffee into the filter and level the bed of grounds by gently shaking.
4. Slide the funnel into the funnel rails.
5. Place an empty server under the funnel that matches the selected batch size.
6 Place the On/Off switch in the lighted upper position. Momentarily press and release the start switch.
7. 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.
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.
