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 controlsonly 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
•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,
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.
PREPARING THE BREWER FOR USE
NOTE: THE BREWER IS NOT READY TO PLUG IN.
Do NOT plug in until Step #11.
1. Open the lid and place the funnel beneath the sprayhead.
3.Place the decanter on the warmer.
5.Wait three minutes while the tank partially fills.
7.Remove decanter from the warmer and pour in another full decanter of water.
9. Close the lid.
13.Press the bottom of the vacation switch.
2.Pour in a full decanter of water.
4.Close the lid. (This starts the flow of water into the tank.)
6. Open the lid.
8.Place the decanter on the warmer.
10.Wait until water flows from the funnel.
12.Now plug in the brewer.
14.Wait fifteen minutes for the water in the tank to heat.
BREWING DELICIOUS COFFEE
1.Insert a BUNN® coffee filter into the brew funnel.
2. Measure coffee into the filter and shake gently to level the bed of grounds.
(Always use Bunn® filters for proper brewing. There is a difference.)
(Use one to two level tablespoons of fine or drip grind per cup of coffee. Vary the amount to suit your taste.)

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.
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.
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.
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
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.

Large burrs flake beans (not pulverize) to the correct size and shape for maximum flavor extraction. High capacity bean hopper keeps up to one full pound of coffee fresh for days.
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.)
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)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.
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.
(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
