CLEANING
1. The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all
surfaces on Bunn-O-Matic equipment. Do NOT clean this equipment with a water jet device.
2. Check and clean each sprayhead. The sprayhead holes must always remain open.
NOTE: Any buildup on the sprayhead may restrict water flow, and impact your coffee brewing. For consis-
tently great coffee, clean sprayheads weekly. Upon visual inspection it may appear that light passes through
all holes in the sprayhead plate, but a thin film of residue can pass light and still impede water flow.
3. Remove sprayhead from brewer. Disassemble by removing the seal.
4. Use the pointed end of sprayhead cleaning tool to remove any mineral deposits from the sprayhead holes.
5. Insert the long end of sprayhead cleaning tool into the sprayhead fitting, and rotate several times to remove
any mineral deposits from the fitting.
6. Insert the short end of sprayhead cleaning tool into the bypass fittings, and rotate several times to remove
any mineral deposits from the fitting.
7. Reassemble sprayhead and reattach. Sprayhead only needs to be hand tightened.
See page 30 of instruction manual for calibration routine to verify sprayhead flow rate matches programmed
flow rate. Machine may need to be re-calibrated due to lime build up. If machine is cleaned and build up
removed, machine must be re-calibrated to achieve desired volumes.

GLOSSARY
BREW LOCKOUT: The inability to initiate a brew if the water temperature is less than the ready temperature
programmed into the brewer.
BREW METER: The setting of a pulse brew routine by entering in the total desired water delivery time. The brewer
will then calculate and perform a pulse brew routine using a predetermined formula.
BYPASS: The process of diverting a portion of the brew water to the outside of the paper filter so that it does not
pass through the coffee grounds. This process is sometimes used to optimize the flavor of the finished brew.
DRIP TIME: The length of time from when the water spray over the grounds ends to the time when no water or
product drips from the funnel tip.
ENERGY SAVINGS MODE: If enabled, the heaters will either shut down or reduce the tank holding temperature
to 140°F (60°C) after the set idle time.
FACTORY DEFAULTS: The factory preset brew settings that were installed into the brewer’s memory.
FIRST ON-TIME: During a pulse brew, this is the time set for the initial flow of water over the grounds.
FRESHNESS TIMER: If enabled, the brewer will display an alert if a new coffee batch has not been brewed before
the set time has expired.
FUNNEL LOCK: A solenoid controlled plunger locking mechanism which engages when a brew cycle has begun
preventing the removal of the funnel until end of Drip Time.
FUNNEL SENSING COIL: A sensor at the front of the brewer that reads what name and batch size of coffee was
ground into the funnel and allows for the brewer to automatically set itself to what is read from the funnel handle.
Also used to read in recipe and ad card information.
IDLE TIME (ENERGY SAVINGS MODE): If ENERGY SAVINGS Mode is enabled, the length of time the brewer is
inactive before the heaters turn off or hold at 140°F (60°C).
LAST ON-TIME: During a pulse brew, this is the time set for the second on-time and each alternative on-time for
the remainder of the brew.
MAIN SCREEN: The term used to describe the screen that is displayed when the brewer is not in use. This screen
is also displayed after exiting the programming mode.
MANUAL PULSE BREW SETUP: The setting of a pulse brew routine by manually entering in the 1st on time, off
time and last on time.
SET TEMP: The temperature at which the tank will heat to and hold.
OFF-TIME: During a pulse brew or preinfusion, this is the time set for the length of time that the water is not
spraying over the grounds.
PREINFUSION: The process of beginning a brewing cycle with an initial spray of water onto the grounds followed
by a pause in the spray. After the programmed pause, the spray continues without interruption until the end of
the brewing cycle.
PULSE BREW: The process that allows the brew water to start, and then stop, repeatedly over the grounds in
order to derive the best flavor from the coffee. Pulse brew is also used in some instances to prevent a funnel
overflow.
CLEAN MODE: If enabled, the brewer will display a message after a set amount of time indicating the machine
needs cleaning and sanitizing.
WARNING TIME (FRESHNESS TIMER): If the Freshness Timer is enabled, the length of time from when the brew
was completed until a “Freshness Alert” message will display, communicating that a fresh batch of product needs
to be brewed.

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 120-240 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.
