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 left 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 non-heated thermal carafe
server. The stainless steel construction will hold coffee at
serving temperature for 2 hours minimum.
• The carafe lid reduces coffee evaporation and temperature loss.
• 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.
• 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.

Raise the hinged flip-lid.
NOTE: The post protruding from the screen is con-
nected to a stopper that controls the flow of water
into the tank. When lid is closed (post depressed), the
stopper is raised and water will flow into the tank.
Plug in the brewer.
Step 2
Slide an empty brew funnel into the brewer. Pour one
carafe full of water into the screened area on top of the
brewer (there is no need to have the lid on the carafe at
this time). Place carafe in position on the brewer. Close
lid. Wait three minutes to allow the water to flow into
the tank. Repeat this process. When the tank is full,
some water will flow through the funnel and into the
carafe. Leave the carafe in place.

Insert a BUNN® coffee filter into the brew funnel.
Be sure to use BUNN® coffee filters for proper
brewing. Order more paper filters direct from
BUNN® at www.bunn.com
Measure coffee into the filter and gently shake the
filter to level the bed of grounds. To determine the
amount of coffee to be used, see Page 8.
Make sure that the sprayhead is tight. Slide the brew
funnel into the brewer.
Raise the hinged flip-lid and pour a carafe of water into
the top of the brewer. See Brewing Tips (page 8) for pre-
heating the carafe. Place the carafe on the brewer, THEN
close the lid. Your BUNN® brewer will begin brewing
coffee immediately. Flip-lid should also remain closed
when brewer is not in operation.

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 carafe. When 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 (USE WITH CAUTION)
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 coffee. The amount of coffee
used and the amount of water passed through the coffee determines strength.
Increasing the amount of coffee results in a stronger beverage. Decreasing
the amount of coffee with the same amount of water results in a weaker
beverage.
As the amount of 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 after all of the desirable elements have been
extracted.
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 coffee brewer.
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. Minimum batch is 20 ounces.
5) After filling the pour-in bowl with water from the carafe, the carafe can be
pre-heated by filling it with hot water for approximately 1/2 minute. Empty
before filling with fresh brewed coffee. For the freshest flavor, don’t hold
brewed coffee in the carafe for longer than four hours.

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) Unscrew the sprayhead 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 carafe of fresh water into the brewer, set the
empty carafe on the brewer, 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.
ROUTINE CLEANING
Rinsing the brew funnel and carafe 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 carafe may be disassembled
for cleaning. Rotate the lid counterclockwise to remove.
Occasionally, the FlavorGard® valve should be removed and
cleaned. Lift at the edge and pull up. After rinsing, replace
by aligning the tab on the FlavorGard® valve with the slot
inside the carafe lid and press in place. Use of a mild, non-abrasive detergent is
recommended. Do not use a scrub pad or other abrasive cleaning device as this
will scratch the stainless steel surface. (The brew funnel and carafe are top-rack
dishwasher safe.)

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 carafe. While this is not unusual in coffee brewing, it can
be avoided by using slightly less coffee, a courser grind, or both. If the overflow
persists, please contact BUNN® to order a special sprayhead free of charge.

PERIODIC CLEANING
(Recommended at least every three months)
1) Slide an empty brew funnel into the brewer and center an empty carafe in
position on the brewer.
2) Pour one quart of white vinegar into the top of the brewer and close the
lid. Empty the carafe 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 carafe of fresh, cold water through the brewer. Place
carafe on brewer base, then close the lid to allow the water to run through
the brewer. After it has run through, empty carafe, and repeat the process
approximately 8 - 10 times. Proceed to Step 9.
6) Cool the brewer by pouring a full carafe of fresh, cold
water into the top of the brewer. Place carafe on brewer
base, close lid. When water has stopped flowing from the
brewer, empty the carafe. Repeat this process, then set
the carafe aside.
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 carafe of water into the top of the brewer.
Place the carafe on the brewer, close the lid. Repeat this
process with another carafe of water. Water will flow out
of the funnel after the second carafe. When flow from the
funnel has stopped, empty the carafe and pour an additional carafe of water
into the brewer. Place the carafe on the brewer 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 carafes
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.
