BREWING DELICIOUS COFFEE
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 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.
HOTWATER (USEWITH 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 goodrecipe.Propercoffeebrewingrequiresqualityequipmenttopreciselycontrol 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.

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,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
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.
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.
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 water has stopped ﬂowing from the brewer, empty the decanter. Repeat this process one more time,then set the decanter aside.
PERIODIC CLEANING (cont.)
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
Place the decanter on the warmer, close the lid. Repeat
this 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.
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.
