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.
"B" models require 2-wire,
WHITE

Proceed as follows:

P2185
Electrical Hook-Up (Model "B" Only)
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. Placetheheaterswitch, locatedon theleftfrontofthecontrolpanelon"B"Models, inthe"OFF"(lower)position.
4. Remove the front panel beneath the sprayhead.
5. Feed the cord through the strain relief and connect it to the terminal block.
6. Connectthebrewertothepowersourceandverifythevoltageattheterminalblockbeforeproceeding. Replace
the front panel.
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. On "B" Models, place the heater switch of the brewer in the "OFF" (lower) position and connect the brewer to
the power source.
4. Pour three pitchers of tap water into the screened area on top of the brewer. Allow approximately two 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
and wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Some water
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. Afterwaterhasstoppedflowingfromthefunnel, allowthewaterinthetank toreheattothepropertemperature.
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, andrepairofelectricalequipmentshouldbeperformedonlybyqualifiedservicepersonnel.
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.
•
Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an
intermittent condition is encountered, the cause will likely be a switch contact or a loose connection at a
terminal or crimp.
•
•
Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are
energized for more than ten minutes without a supply of water.
Theuseoftwowrenchesisrecommendedwheneverplumbingfittingsaretightenedorloosened. Thiswillhelp
to avoid twists and kinks in the tubing.
•
•
Make certain that all plumbing connections are sealed and electrical connections tight and isolated.
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
