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.

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).  
Avacationswitchisprovidedonthelowerrightsidetocompletelyshut  
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  
andallowthewaterinthetanktoheattothepropertemperaturebefore  
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  
temperatureontheporcelaindecanterwarmer.Thewarmeriscontrolled  
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.

P2769  
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® 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. 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.  
DECANTER HANDLE MAINTENANCE  
Using a standard screw driver, periodically tighten the screw in the  
handle. Be careful not to overtighten the screw.

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 top-  
rack dishwasher safe.)  
DELIMING  
Periodically, you should delime the brewer to clear any  
deposits that may have accumulated due to impurities in the  
water source.  
P2776  
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) Insertallbuttwoinchesoftheflexibledelimingtool(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.  
P2774  
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.  
P2775  
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, pouradecanteroffresh, coldwaterthroughthebrewer. Placedecanteron  
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.

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.Pouradecanterofwaterintothetopofthebrewer.  
Placethedecanteronthewarmer,closethelid. Repeatthis  
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.  
P0319  
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.  
P2774  
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.

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.
