IMPORTANT SAFEGUARDS
Follow these basic safety precautions when using electrical appliances
to reduce the risk of fire, electric shock, and/or personal injury:
SAVE THESE INSTRUCTIONS
•Ashort 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 and 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 & 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).
•Avacation switch is providedonthe lower leftsideto completely shut
off all electrical components when your plans take you away from
homeforthreeormoredays.Safetyfeatures,designedintotheBUNN®
coffee brewer, make the daily use of this switch unnecessary.
•Wheneverthebrewerhasbeenshutofforunplugged,fillthetankwith
waterandallowthewaterinthetanktoheattothepropertemperature
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 the correct method of brewing 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.
•Whilecoffeeisbeingbrewed,thenewestwaterinthetankisheatedto
the proper temperature and held until needed.
•When thebreweris not in operation,theflip lid should remainclosed.
Leaving the lid open may cause an unexpected drip of water from the
sprayheadoncecoldwaterhasbeenpouredintothetopofthebrewer.
•UseCAUTION whendispensinghotwaterfromthebrewer.Thewater
is approximately 50°F hotter than that available from your hot water
faucet and is always available for other uses.
•Thebrewerisequippedwithapolarizedcordset.Onebladeoftheplug
is slightly larger than the other. This is a safety feature and allows the
plug to fit into the outlet only one way. If you are unable to insert the
plug into the outlet, try turning it over. If the plug still does not fit,
contact an electrician to update your outlet. Do not attempt to bypass
the safety aspect of this polarized plug.
•The sprayhead will periodically become loose. Using extreme caution
not to burn yourself, retighten the sprayhead with your finger tips.
NOTE- A severe burn may result if the sprayhead becomes
loose and falls off while brewing.

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.

COFFEE FUNDAMENTALS
Brewing delicious coffee is similar to cooking any favorite food. Both
require a good recipe. Proper coffee making needs quality equipment to
preciselycontrolwatertemperature,volume,andbrewtime.TheBUNN®
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, some
desirable, some not. 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 it in an airtight container.
BREWING TIPS
When 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 BUNNcoffee brewer.
You'll always have a great coffee experience if you follow these tips:
1) Always start with clean equipment.
2) Always use fresh cold water.
3) Always use BUNN®paper coffee filters for proper extraction.
4) Usingaminimumof2ouncesoffreshdripgrindcoffeeforeachfullpot
willgive you aconsistentlygreat pot ofcoffee with afull-bodiedflavor
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) Afterfillingthepour-inbowlwithwaterfromthecarafe,thecarafecan

Empty before filling with fresh brewed coffee. For the freshest flavor,
don't hold brewed coffee in the carafe for longer than four hours.

ROUTINE CLEANING
Rinsing the brew funnel and carafe after each use is
theonlyroutinecleaningrequired.Occasionally,wipethe
outsideofthe brewerincluding the areaabove the funnel
with a damp cloth. The carafe may be disassembled for
cleaning. Rotate the lid counterclockwise to remove.
Occasionally,theflavorgardvalveshouldberemovedand
cleaned.Liftattheedgeandpullup. 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.)

DELIMING
Periodically,youshoulddelimethebrewertoclearanydepositsthatmayhave
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) Slidethetool inandout fiveorsix timestoloosen limein
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.
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
todrainmoreslowlythrough thepaperfilter,occasionallyresultingin anoverflow
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.
