ELECTRICAL INSTALLATION INSTRUCTIONS  
NOTE: Electrical source should have a circuit breaker between the brewer and the main supply which breaks all  
poles with a contact separation of at least 3 mm.  
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. Before electrically connecting the brewer, remove the front cupola cover (some models have the thermostat  
knob on the outside of the cover) and rotate the thermostat knob fully counterclockwise to the "OFF" position.  
Keep this knob in the "OFF" position until performing the Initial Setup.  
4. Electrical service is connected at the upper rear of the single service and scrambler brewers using a junc-  
tion box. On double service brewers the rear decorative channel must be removed for access to the terminal  
block.  
5. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Re-  
place all panels.  
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 Setup.  
NOTE: Schematic wiring diagrams are included in this manual.

CE REQUIREMENTS  
• This appliance must be installed in locations where it can be overseen by trained personnel.  
• For proper operation, this appliance must be installed where the temperature is between 5°C to 35°C.  
• Appliance shall not be tilted more than 10° for safe operation.  
• An electrician must provide electrical service as specified in conformance with all local and national codes.  
• This appliance must not be cleaned by water jet.  
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental  
capabilities, or lack of experience and knowledge, unless they have been given instructions concerning use of  
this appliance by a person responsible for its safety.  
• Children should be supervised to ensure they do not play with the appliance.  
If the power cord is ever damaged, it must be replaced by the manufacturer or authorized service personnel with  
a special cord available from the manufacturer or its authorized service personnel in order to avoid a hazard.  
PLUMBING REQUIREMENTS  
These brewers must be connected to a cold water system with operating pressure between 20 (138) and 90 psi (620 kPa)  
from a 1/2" or larger supply line. A shut-off valve should be installed in the line before the brewer. Install a regulator in the  
line when pressure is greater than 90 psi (620 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is 3/8" flare.  
NOTE - Bunn-O-Matic recommends 3/8" copper tubing for installations 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 recom-  
mend 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.  
ThisequipmentmustbeinstalledtocomplywiththeInternationalPlumbingCodeoftheInternational  
Code Council and the Food Code Manual of the Food and Drug Administration (FDA). For models  
installed outside the U.S.A., you must comply with the applicable Plumbing/Sanitation Code for  
your area.  
INITIAL SETUP  
CAUTION - The brewer must be disconnected from the power source throughout the initial setup, except when specified  
in the instructions.  
IMPORTANT: Brewer must be level and installed on a sturdy structure.  
Electrician's and Plumber's Instructions are provided. These instructions should be carefully followed  
before proceeding with initial setup.  
Be sure all electrical and plumbing connections are tight.  
1. Open manual fill valve located on the bottom of the brewer. Water should start filling the tank. When water is visible  
in the hot water gauge glass (center spigot), close valve. Approximate time for filling manually is 3 minutes.  
CAUTION: Never leave brewer unattended while manually filling tank.  
2. Connect the brewer to the power source. Turn "ON/OFF" switch to the "ON" position. Water should finish filling tank  
automatically.  
NOTE: It is recommended that the "ON/OFF" switch be left in the "OFF" position at the end of the operating day or when  
unattended for a long period of time.  
3. Disconnect the brewer from the power source. Remove front cupola cover for access to thermostat knob and timer.  
On some brewers the thermostat knob is located on the front of the cupola cover.  
4. Turn the thermostat knob clockwise to an approximate 5 o'clock position. Allow 1-1/2 hours for water to heat. Time  
will vary with incoming water temperature.  
5. On initial warm-up, some water may flow thru the overflow spigot due to expansion of the cold water in the tank.  
This will not recur during the use of the brewer and may be avoided on the initial warm-up by drawing off 1/2 gallon  
decanters of water each 15 minutes till brewing temperature is reached.  
10060 102808  
Page 5  
INITIAL SETUP (cont.)  
6. Brewing cycles may be started whenever water temperature is correct. This condition is indicated by the dial  
thermometer on front of the brewer. Whenever the pointer is in the green, brewer is ready for brewing. The  
recommended brewing temperature is approximately 200° F (93°C). Water temperature may be increased by  
turning thermostat knob clockwise, decreased by turning knob counterclockwise.  
7. When desired temperature is reached, insert funnel support, funnel and funnel cover in position. Be sure  
the water swing spout is over the center of the funnel cover, turn "ON/OFF" switch to the "ON" position, push  
and release "START" and run a brew cycle of hot water only. At the end of this cycle, brewer will be ready for  
checking timer adjustment.  
8. The timer has been preset for a 4 minute cycle. This setting will deliver approximately 3 gallons of water per  
brewing cycle. To increase or decrease amount of water, adjust the timer as required. See Adjusting Brew  
Volumes.  
9. Having determined final settings of the thermostat and the timer, replace front cupola cover. Brewer is now  
ready for brewing coffee.  
ADJUSTING BREW VOLUMES  
CAUTION - Disconnect the power source from the brewer prior to the removal of any panel for the replacement  
or adjustment of any component.  
NOTE: Prior to setting or modifying batch sizes, check that the brewer is connected to water supply, the tank is  
properly filled, and a funnel support, funnel and funnel cover are in place.  
1. Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET” posi-  
tion on the circuit board.  
To increase a batch size. Press and hold the START or BREW switch until you see three breaks in the water  
stream from the swing arm. Release the switch (Failure to release the switch within two seconds after the  
third break in the water stream 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 decrease a batch size. Press and release the START or BREW switch once for every two-second interval  
to be removed from the total brew time period; then immediately press and hold down the START or BREW  
switch until you see three breaks in the water stream from the swing arm. Release the switch. (Failure to  
release the switch within two seconds after the third break in the water stream causes the volume setting to  
be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to  
verify that the desired volume has been achieved.  
2. Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the “SET” position on  
the circuit board. Press and hold the START or BREW switch until you see three breaks in the water stream  
from the swing arm, and then release the switch. (Failure to release the switch within two seconds after the  
third break in the water stream causes the volume setting to be aborted and previous volume setting will  
remain in memory). View the level of the liquid being dispensed. When the desired level is reached, turn the  
ON/OFF switch to “OFF” (lower). The brewer remembers this volume and will continue to brew batches of  
this size until the volume setting procedure is repeated.  
NOTE: When brewing coffee, batch volumes will decrease due to absorption by the coffee grounds.  
NOTE: HALF-BATCH AND FULL BATCH SETTINGS MUST EACH BE SET SEPARATELY.  
3. Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times  
once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will prevent any program-  
ming to be done until switch is once again placed in the “SET” position.

COFFEE BREWING  
1. Brewing cycles may be started whenever water temperature is correct. This condition is indicated by the dial  
thermometer on front of the brewer. Whenever the pointer is in the green, brewer is ready for brewing.  
2. Insert Bunn® filter in funnel and add desired amount of coffee.  
3. Level the bed of coffee and place funnel into the funnel support. Place funnel cover over the funnel and be  
sure the water swing spout is over the center of the funnel cover.  
4. Turn "ON/OFF" switch to the "ON" position.  
5. Push and release "START" switch to start the brew cycle.  
6. Water swing spout should not be moved as long as water is flowing into the funnel cover. When water stops  
flowing, it may then be moved for access to brewing funnel.  
7. Remove funnel cover. Funnel should not be removed from brewer until drip out of coffee has been com-  
pleted.  
8. To empty funnel, invert it over a waste container to dispose of filter and grounds. An additional flange is  
provided on the funnel to help make this step easier.  
NOTE: Hot water may be drawn from the hot water faucet during a brew cycle. However, if a large amount of  
hot water is drawn off (over 1 gallon) operator should wait to do so between brewing cycles.  
CLEANING  
NOTE: Tanks and tank components should be delimed regularly based on local water conditions. Excessive  
mineral build-up on stainless steel surfaces can initiate corrosion reactions resulting in serious leaks.  
1. Remove both funnels, funnel lids and supports, under hot water, rinse away all coffee oils. Wipe with a clean  
damp cloth.  
2. Drain both coffee reservoirs by opening coffee faucets. When empty, close faucets.  
3. Cycle two or three inches of water into each coffee reservoir and scrub entire reservoir area.  
NOTE: The brewer must NOT be rinsed or cleaned by a water jet device.  
4. Drain both coffee reservoirs and rinse. Use clean damp cloth to wipe both reservoirs.  
5. Install both coffee funnel supports, funnels and funnel lids.  
6. Remove the sight gauge cap, insert sight gauge cleaning brush into the sight gauge glass tube and clean.  
7. To clean coffee faucets, remove the faucet handle from the faucet and faucet clean out cap. Clean faucet with  
a faucet cleaning brush and wipe all parts with a damp cloth. Replace faucet seat cups periodically if badly  
stained or to stop faucet dripping. DO NOT CLEAN THE HOT WATER FAUCET.  
8 Reassemble the coffee faucets.  
9. Wipe the entire outside surface of the machine with a clean damp cloth. Wipe dry.  
FILTER HOLDER  
1. A filter holder is supplied with each U3 coffee brewer. Its purpose is to keep the filters in their originally  
formed shape to properly fit the brewer funnel.  
2. It is suggested that only one cluster of filters be placed in the holder at one time for best results.  
3. Not using the filter holder may permit the filters to gradually widen out towards a flat shape, especially so if  
humidity is present. Once a filter has lost its upright side walls, it may tend to collapse inward when placed  
in the brewing funnel. If this happens the hot water spray may cause one side to fall inwards, letting coffee  
grounds flow over the edge of filter and into the brewed coffee. Proper use of the holder should prevent this  
problem.

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 person-  
nel.  
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.  
The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will  
help 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

NOTE: The brewer remembers this volume and will  
continue to brew batches of this size until the volume  
setting procedure is repeated.  
NOTE: All volume settings must be done with the  
sprayhead installed.  
NOTE: When brewing coffee, volume will decrease  
due to absorption by the coffee grounds.  
NOTE: Half-Batch and full batch settings must each  
be set separately.  
1. Modifying brew volumes. To modify a brew vol-  
ume, first check that the SET/LOCK switch is in the  
“SET” position on the circuit board.  
To increase a brew volume, place the ON/OFF  
switch in the “ON” position, press and hold the START  
switch until you see three breaks in the water stream  
from the swing arm. Release the switch and press it  
again one or more times. (Failure to release the switch  
within two seconds after the third break in the water  
stream causes the volume setting to be aborted and  
previous volume setting will remain in memory.) 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.  
3. Setting programming disable feature. If it be-  
comes necessary to prevent anyone from changing  
brew time once programmed, you can set the SET/  
LOCK switch to the “LOCK” position. This will prevent  
any further programming until switch is once again  
put into the “SET” position.  
To decrease a brew volume, place the ON/OFF  
switch in the “ON” position, press and release the  
START switch once for every two-second interval  
to be removed from the total brew time period; then  
immediately press and hold down the START switch  
until you see three breaks in the water stream from the  
swing arm. Release the switch. (Failure to release the  
switch within two seconds after the third break in the  
water stream causes the volume setting to be aborted  
and previous volume setting will remain in memory).  
Allow the brew cycle to finish in order to verify that  
the desired volume has been achieved.  
2. Setting brew volumes. To set a brew volume,  
first check that the SET/LOCK switch is in the “SET”  
position on the circuit board. Place the ON/OFF switch  
in the “ON” position, press and hold the START switch  
until you see three breaks in the water stream from  
the swing arm and then release the switch. (Failure to  
release the switch within two seconds after the third  
break in the water stream causes the volume setting  
to be aborted and previous volume setting will remain  
in memory.)
