IMPORTANT SAFEGUARDS
Follow these basic safety precautions when using electrical appliances
to reduce the risk of fire, electric shock, and/or personal injury:
• Read all instructions.
• Do not touch hot surfaces. Use
handles or knobs.
• Do not place cord, plugs, or
brewer in water or liquid.
• Close supervision is necessary
when the brewer is used by or
near children.
• Unplug from outlet when not in
use for extended periods of time
and before cleaning. Allow to
cool before putting on or taking
off parts, and before cleaning.
• Do not operate the brewer with
a damaged cord or plug or if the
brewer malfunctions or is
damaged in any manner. Return
the brewer to an Authorized
Service Facility for
examination, adjustment, or
repair. (Refer to page 11.)
• The use of an accessory not evalu-
ated for use with this brewer
may cause injuries.
• For household use only. Do not
use outdoors.
• Do not let cord hang over edge
of table or counter or touch hot
surfaces.
• Do not place the brewer on or
near a hot gas or electric burner
or in a heated oven.
• Do not use brewer for other than
its intended use.
• Do not place or remove funnel,
or decanter while brewing.
• The decanter must not be used
on a range top or in a microwave.
• Do not set a hot decanter on a
cold surface.
• Do not use a cracked decanter
or a decanter having a loose or
weakened handle.
• Do not clean decanter with
cleansers, steel wool pads, or
other abrasive materials.
• When the brewer is idle, the lid
should be in the closed position.
SAVE THESE INSTRUCTIONS
• A short power-supply cord is used to reduce the risks resulting from
becoming entangled in or tripping over a longer cord.
• If an extension cord is used, the marked electrical rating of the
extension cord should be at least as great as the electrical rating of
the brewer. The cord should be arranged so that it will not hang
over edge of table or counter where it can be pulled on by children
or tripped over.
• The extension cord must be of the 3-pronged, 3-socketed, grounding
type, 3-wire cord. (Including grounding conductor).

GENERAL INFORMATION
NOTE - THE BREWER IS NOT READY TO PLUG IN
(See Page 6)
Improper installation will result in permanent damage and void the
limited warranty. Read and follow the instructions on the next page.
• This brewer is designed to remain plugged in at all times
(except during initial installation or when cleaning).
• A vacation switch is provided on the lower right side to completely shut
off all electrical components when your plans take you away from
home for three or more days. Safety features, designed into the BUNN
coffee brewer, make the daily use of this switch unnecessary.
• If the brewer has been shut off or unplugged, fill the tank with water
and allow the water in the tank to heat to the proper temperature before
using (about fifteen minutes or until the heating sound stops).
• Your BUNN® coffee brewer has a specially designed tank to keep the
water at the proper temperature. This constant supply of hot water
assures correctly brewed coffee in less than three minutes.
• The brewed coffee flows into a decanter where it is kept at serving
temperature on the porcelain decanter warmer. The warmer is controlled
by the lighted on/off switch on the front of the brewer.
NOTE: The warmer switch controls only the decanter warmer.
• While coffee is being brewed, the newest water in the tank is heated to
the proper temperature and held until needed.
• When the brewer is not in operation, the flip-lid should be closed. If the
lid is left open, water could drip from the sprayhead when cold water
is poured into the top of the brewer.
• The decanter lid reduces coffee evaporation and temperature loss.
• Use CAUTION when dispensing hot water from the brewer. The water
is approximately 50°F hotter than that available from your hot water
faucet and is always available for other uses.
• The brewer is equipped with a 120 volt, 3-prong, grounded cord set.
The plug is provided with a round grounding pin. This is a safety feature
and allows the plug to fit into a properly grounded outlet. If the plug
does not fit into the outlet, contact an electrician to update your outlet.
Do not attempt to bypass the safety aspect of this plug.
• The sprayhead may periodically become loose. Using extreme caution
since it may be hot, retighten the sprayhead with your finger tips.
NOTE: A severe burn may result if the sprayhead becomes
loose and falls off while brewing.

cold water.

(NOTE - you must add a minimum of four cups, as indicated on the decanter, to brew.)
7. Turn on the
warmer.
8. Close the lid to
start the flow of
water into the
tank.
P2772
9. When brewing has stopped, remove the brew funnel and discard the filter and grounds. Do
not touch hot grounds.
NOTE: Opening the lid during brew cycle will interrupt the flow of water into the tank, but will
not interrupt the brewing process. The brewed coffee already in the funnel will empty into the
decanter. When the lid is closed, the flow of water into the funnel will resume until the brewing
cycle is complete.
WARNING: Do not close the lid after pouring in water, without the decanter in place. Closing
the lid releases the hot water.
HOT WATER
The same basic steps can be used to obtain hot water by omitting the filter and coffee. The
water from your BUNN® coffee brewer is approximately 200°F. This is hotter than the hot water
from your faucet and must be handled with care.

COFFEE FUNDAMENTALS
Brewing delicious coffee is similar to cooking any favorite food. Both require
a good recipe. Proper coffee brewing requires quality equipment to precisely
control water temperature, volume, and brew time. The BUNN
®
coffee brewer
assures consistency in your recipe by controlling all of these elements. The only
variables remaining in the recipe are the grind and amount of coffee used.
The amount of ground coffee is generally determined by the grind. For best
results, we recommend a drip (medium) grind.
Hot water extracts many elements from the ground coffee. The taste and
aroma are referred to as strength, the acidity as bitterness. Increasing the amount
of ground coffee results in a stronger beverage, and decreasing it results in a
weaker beverage.
As the amount of ground coffee decreases, you'll note an increase in the
bitterness of the beverage. This happens because the hot water begins to remove
the undesirable elements such as acidity after all of the desirable tastes and aroma
have been removed.
Fresh-ground coffee gives the best results. Always store the ground coffee in
a cool, dry area away from other food items with strong odors. When stored in
a refrigerator, keep coffee in an airtight container.
BREWING TIPS
When coffee is properly brewed, the difference between the best quality
ground coffee and a poor quality ground coffee becomes very dramatic. Proper
brewing requires little effort with the BUNN
You'll have a great coffee experience if you follow these tips:
1) Start with clean equipment.
2) Use fresh cold water.
3) Use BUNN
®
paper coffee filters for proper extraction.
4) Using a minimum of 2 ounces of fresh drip grind coffee for each full pot will
give you a consistently great pot of coffee with a full-bodied flavor and aroma.
However, the real criteria is personal taste. Adjust the recipe until it suits
you. If you need to make a smaller batch, experiment with less water
and ground coffee. The minimum batch is 4 cups as indicated on the
decanter.
5) Keep the beverage at the correct serving temperature by setting the decanter
on the porcelain warmer. For the freshest flavor, do not hold brewed coffee
on the warmer for longer than an hour.

ROUTINE CLEANING
Rinsing the brew funnel and decanter after each use is
the only routine cleaning required. Occasionally, wipe the
outside of the brewer including the area above the funnel
with a damp cloth. (The brew funnel and decanter are toprack dishwasher safe.)
DELIMING
Periodically, you should delime the brewer to clear any
deposits that may have accumulated due to impurities in the
water source.
NOTE- Unplug the brewer and let it cool down before
deliming.
1) Remove the sprayhead by turning it one quarter turn to the
left (counterclockwise) with your fingertips and set it aside.
2) Insert all but two inches of the flexible deliming tool (supplied)
into the sprayhead tube.
3) Slide the tool in and out five or six times to loosen lime in the
sprayhead tube. Remove the tool.
4) Pour one decanter of fresh water into the brewer, set the
empty decanter on the warmer, and close the lid.
5) Check the holes in the sprayhead. If plugged with lime, they
may be cleared by using a toothpick. Clean the sprayhead
with a cloth and mild detergent. Rinse the sprayhead with
water before reinstalling.
6) Plug in the brewer and allow the water in the tank to reheat
before using. The frequency of
deliming depends on the mineral content of your water.

PERIODIC CLEANING
(Recommended at least every three months)
1) Slide an empty brew funnel into the brewer under the warmer switch and center an
empty decanter on the warmer.
2) Pour one quart of white vinegar into the top of the brewer and close the lid. Empty
the decanter when liquid stops flowing from the funnel.
3) Allow the brewer to sit for two hours.
4) Unplug the brewer. Remove the brew funnel and sprayhead from the brewer and
set them aside. Clean the sprayhead with a cloth and mild detergent.
5) To drain the brewer, continue to Step 6, OR to clear vinegar out of brewer without
draining, pour a decanter of fresh, cold water through the brewer. Place decanter on
warmer, then close the lid to allow the water to run through the brewer. After it has
run through, empty decanter, and repeat the process approximately 8 - 10 times.
Proceed to Step 9.
6) Cool the brewer by pouring a full decanter of fresh, cold water into the top of the
brewer. Place decanter on the warmer, and close the lid. When water has stopped
flowing from the brewer, empty the decanter. Repeat this process, then set the
decanter aside.
10
7) Grasp the back of the brewer and quickly turn it upside down over a sink as shown.
Most of the water in the tank will flow from the sprayhead
tube opening. Some water may flow from the area around
the top lid. Continue tipping the brewer until the flow
stops.
8) Replace the sprayhead and funnel after the water has been
drained. Pour a decanter of water into the top of the brewer.
Place the decanter on the warmer, close the lid. Repeat this
process with another decanter of water. Water will flow
out of the funnel after the second decanter. When flow
from the funnel has stopped, empty the decanter and pour
an additional decanter of water into the brewer. Place the
decanter on the warmer and close the lid.
9) If you have not replaced the sprayhead and funnel, do so
now before proceeding. Taste the water coming out of the
brewer. Pour additional decanters of fresh, cold water into
the brewer as needed until the water has no vinegar taste.
10) Plug in the brewer and allow the water in the tank to reach brewing temperature
before using. (approximately 15 minutes.)

DRAINING THE BREWER
The water in your BUNN® Coffee Brewer should be emptied whenever it is taken on
a trip, shipped, or stored in an unheated location with a chance of freezing. Follow steps
4-7 of the PERIODIC CLEANING section.
WATER QUALITY
Install a water conditioner if your water contains excessive amounts of sediment, taste,
or odors.
SOFTENED WATER / DECAFFEINATED COFFEE
Use of decaffeinated coffee and/or softened water may cause the brewed coffee to drain
more slowly through the paper filter, occasionally resulting in an overflow of grounds
into the decanter. While this is not unusual in coffee brewing, it can be avoided by using
slightly less coffee, a coarser grind, or both. If the overflow persists, please contact Bunn
to order a special sprayhead free of charge.
