SAVE THESE INSTRUCTIONS
•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.
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).
•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.
•Whenever 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 the correct method of brewing coffee, in less than three minutes.
•The brewed coffee flows into the 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 switchonly controls 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 remain closed.
Leaving the lid open may cause an unexpected drip of water from the sprayhead once cold water has been 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 polarized cordset. One blade of the plug 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.
PREPARING THE BREWER FOR USE
NOTE - THE BREWER IS NOT READY TO PLUG IN. Do NOT plug in until Step #3.
Raise the hinged
NOTE: The post protruding from the screen is connected to a stopper which 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.
Slide an empty brew funnel into the brewer under
the warmer switch. Pour one decanter full of water
into the screened area on top of the brewer. Place
decanter on the warmer. 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 decanter.
Plug in the brewer.
Press the bottom of the vacation switch, located on the
lower left side of the brewer, to the "ON" (lower) position.
The vacation switch controls power to the tank heater.
Initially you will have to wait approximately fifteen
minutes in order for the water to reach brew
Empty any water that has collected in the decanter.
You’re not done yet! The next page leads you through the five easy steps to ‘BREWING DELICIOUS COFFEE’
BREWING DELICIOUS COFFEE
Insert a BUNN® coffee filter into the brew funnel. (Be sure to use BUNN® coffee filters for proper brewing. There is a difference.)
Order more paper filters direct from BUNN® at: www.bunnomatic.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 under the warmer switch. Place the lighted warmer switch in the "ON" position.
Raise the hinged
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 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. Thisis 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 making needs 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, 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.
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 BUNN® coffee 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)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, don't 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.

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
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 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 warmer, close lid. When flow from the brewer has stopped, empty the decanter. Repeat this process one more time, then set the decanter aside.
