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 dispenser under the funnel.
3. 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.
4. When the flow of water from the funnel stops, connect the brewer to the power source and wait approxi-
mately 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.
5. Empty the dispenser and replace it under the funnel.
6. Pour one pitcher of tap water into the screened area on top of the brewer.
7. When water has stopped flowing from the funnel let water in the tank reheat to the proper temperature.
8. Empty the dispenser. The brewer is now ready for use in accordance with the coffee brewing instructions
below.
NOTE: The control thermostat will need to be adjusted downward to compensate for high altitudes. Refer to
Steaming and spitting around the funnel on page 5 for 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.

Refer to Service - Limit Thermo-
stat for testing procedures. See
page 10
CAUTION - Do not eliminate or
bypass limit thermostat/thermal
cut-off. Use only BOM replace-
ment part.

Spitting or excessive steaming
1. Lime Build-up
Inspect the tank assembly for
excessive lime deposits. Delime
as required.
CAUTION - Tank and tank com-
ponents should be delimed
regularly depending on local
water conditions. Excessive min-
eral build-up on stainless steel
surfaces can initiate corrosive
reactions resulting in serious
leaks.

SERVICE
This section provides procedures for testing
and replacing various major components used in
this brewer should service become necessary. Refer
to Troubleshooting for assistance in determining the
cause of any problem.
WARNING - Inspection, testing, and repair of electri-
cal equipment should be performed only by qualified
servicepersonnel. Thebrewershouldbedisconnected
from the power source when servicing, except when
electrical tests are required and the test procedure
specifically states to plug-in the brewer.
