Electrical Hook-Up
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
3. Remove the front panel beneath the sprayheads.
Models with electronic control assemblies:
Place the tank heater switch at the top of the control assembly in the “OFF” position.
Models with electromechanical thermostats:
Rotate the control thermostat knob fully counterclockwise to the “OFF” position.
4. Feed the cord through the strain relief and connect it to the terminal block.
5. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Replace
the front panel.
6. If plumbing is to be hooked-up later be sure the brewer is disconnected from the power source. If plumbing
has been hooked-up, the brewer is ready for Initial Set-Up.
PLUMBING REQUIREMENTS
This brewer must be connected to a cold water system with operating pressure between 20 and 90 psi from
1
⁄2" or larger supply line. A shut-off valve should be installed in the line before the brewer. Install a regulator in
a
the line when pressure is greater than 90 psi to reduce it to 50 psi. The water inlet fitting is
NOTE – Bunn-O-Matic recommends 1⁄4" copper tubing for installations of less than 25 feet and 3⁄8" for more than
25 feet from the 1⁄2" water supply line. A tight coil of copper tubing in the water line will facilitate moving the brewer
to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle valve to install the brewer. The
size and shape of the hole made in the supply line by this type of device may restrict water flow.
1
⁄4" flare.
This equipment must be installed to comply with the Basic Plumbing Code of the
Building Officials and Code Administrators International, Inc. (BOCA)
and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).
Plumbing Hook-Up
1. Attach the flare fitting from the short piece of tubing on the flow control (supplied)
to the water inlet fitting on the bottom of the brewer.
2. Flush the water line and securely attach it to the flare fitting on the strainer.
3. Turn on the water supply.
INITIAL SET-UP
CAUTION – The brewer must be disconnected from the power source throughout the
initial set-up, except when specified in the instructions.
1. Remove the front panel beneath the sprayhead.
Models with electronic control assemblies:
Place the tank heater switch at the top of the control assembly in the “OFF” position.
Models with electromechanical thermostats:
Rotate the control thermostat knob fully counterclockwise to the “OFF” position.
2. Connect the brewer to the power source. Water will begin flowing into the tank.
3. When water stops flowing into the tank., remove the front panel and proceed as directed:
Models with electronic control assemblies:
Place the tank heater switch at the top of the control assembly in the “ON” position and replace the front panel.
Models with electromechanical thermostats:
Rotate the control thermostat knob fully clockwise to the “ON” position and replace the front panel.

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 one-gallon
position, the On/Warmer switch in the upper position and initiate a brew cycle.
6. Place the On/Warmer 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 128 ounces.
7. If not, disconnect the brewer from the power source, remove the front panel, and adjust the brew timer dial
for that brew station up-or-down as required. Replace the front panel, connect the brewer to the power source,
allow the water to reheat, start, and measure another brew cycle.
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.

Placing the switch in the
subsequent brew cycles. Repositioning this switch after a brew cycle has been initiated does not change the brew
batch in progress.
On/Warmer Switch
Placing the switch in the unlighted lower position cuts power to the brew station warmer 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 brew station warmer and enables the brew circuit.
⁄2 Gal, 1 Gal, or 11⁄2 Gal position selects the amount of coffee to be brewed in
Start
Momentarily pressing and releasing this switch starts a brew cycle when the On/Warmer switch is in the lighted
upper position.
NOTE – The On/Warmer switch must be in the lighted upper position to initiate and complete a brew cycle.
COFFEE BREWING
1. Select the desired batch size.
2. Insert a BUNN® filter into the funnel.
3. Pour the proper amount of fresh 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.
6 Place the On/Warmer 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.
