ELECTRICAL REQUIREMENTS
CAUTION - The brewer must be disconnected from the power source until specified in Initial Set-Up.
The brewer has an attached cordset and requires 2-wire grounded service rated 120 volts ac, 15 amp, single
phase, 60 Hz.
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. Insert an empty funnel into the funnel rails.
2. Place an empty decanter under the funnel.
3. Place the heater switch of the brewer in the “OFF”lower position and connect the brewer to the power source.
4. Pourthree pitchers oftap water intothe screened areaon top ofthe brewer. Allow approximatelytwo minutes
between pitchers for water to flow into the tank. While the third pitcher of water is entering the tank, the tank
will fill to capacity and the excess will flow from the sprayhead, out of the funnel, and into the dispenser.
5. When the flow of water from the funnel stops, place the heater switch of the brewer in the “ON”upper position
andwaitapproximatelytwentyminutesforthewaterinthetanktoheattothepropertemperature. Somewater
will drip from the funnel during this time; this is due to expansion and should not occur thereafter.
6. Pour one pitcher of tap water into the screened area on top of the brewer.
7. After water has stopped flowing from the funnel, allow the water in the tank reheat to the proper temperature.
8. Empty the decanter. The brewer is now ready for use in accordance with the coffee brewing instructions.
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. Pour one pitcher of tap water into the screened area on top of the brewer.
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.

TROUBLESHOOTING
A troubleshooting guide is provided to suggest probable causes and remedies for the most likely
problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the
Bunn-O-Matic Technical Service Department.
•Inspection, testing, and repair of electrical equipment should be performed only by qualified service
personnel.
•All electronic components have 120 volt ac and low voltage dc potential on their terminals. Shorting
of terminals or the application of external voltages may result in board failure.
•If an intermittent condition is encountered, the cause will likely be a switch contact or a loose
connection at a terminal or crimp.
•This brewer is heated at all times. Keep away from combustibles.
WARNING– •Exercise extreme caution when servicing electrical equipment.
•Unplug the brewer when servicing, except when electrical tests are specified.
•Follow recommended service procedures
•Replace all protective shields or safety notices

Test Procedures:
1. Disconnect the brewer from the power source.
2. Locate the blue wire on the control thermostat.
3. Check the voltage across the blue wire on the
control thermostat and the white wire on the
tank heater with a voltmeter. Connect the
brewer to the power source. The indication
must be 120 volts ac.
4. Disconnect the brewer from the power
source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to the
wiringdiagrams and check the brewer wiring harness.
5. Locate the black wire on the control thermostat.
6. Gently remove the capillary bulb and grommet
from the tank.
7. Check the voltage across the black wire of the
control thermostat and the white wire on the
tank heater with a voltmeter when the con-
trol thermostat is turned "ON" (Fully clock-
wise). Connect the brewer to the power
source. The indication must ber 120 volts
ac.
8. Disconnect the brewer from the power
source.
Ifvoltageispresentasdescribed,reinstallthecapillary
tube into the tank to the line 4.5" above the bulb, the
control thermostat is operating properly.
If voltage is not present as described, replace the
thermostat.
Removal and Replacement:
1. Remove wires from control thermostat leads.
2. Remove the thermostat capillary bulb by firmly
pulling-upon the capillary atthe tank lid. Thiswill
disengage the grommet from the tank lid.
3. Remove the one #8-32 screw securing the
control thermostat to the component bracket
in the trunk.
4. Slide the grommet to the line 4.5" above the
bulb on the new capillary tube.
5. Insert the capillary bulb through the hole in
the tank lid and press the grommet firmly

and evenly so that the groove in the grom-
met fits into the tank lid.
6. Carefully bend the capillary tube so that the tube
and bulb inside the tank are in the vertical posi-
tion.
NOTE - The capillary tube must be clear of any electri-
cal termination and not kinked.
7. Using one #8-32 screw secure the control ther-
mostattothecomponentbracketinsidethetrunk.
