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

• 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.

• The extension cord must be of the 3-pronged, 3-socketed, grounding

type, 3-wire cord. (Including grounding conductor).

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).

• 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.

• 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 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 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 become

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 ﬂip-lid.

NOTE: The post protruding from the screen is

connected to a stopper that 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.

Plug in the brewer.

Step 2

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.

P219

Step 4

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 temperature.

Empty any water that has collected in the decanter.

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 ﬂip-lid and pour a decanter of water

into the top of the brewer. Place the decanter on the

warmer, THEN close the lid. Your BUNN® brewer will

begin brewing coffee immediately. Flip-lid should also

remain closed when brewer is not in operation.

P206

P205

P2241

P2247

P215

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. 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 coffee. The amount of coffee used

and the amount of water passed through the coffee determines strength. Increasing

the amount of coffee results in a stronger beverage. Decreasing the amount of coffee

with the same amount of water results in a weaker beverage. Too much water and

too little coffee can result in over-extraction.

As the amount of 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 after all of the desirable elements have been extracted.

Fresh-ground coffee gives the best results. Always store 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. 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, 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.

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.

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 water has stopped

ﬂowing from the brewer, empty the decanter. Repeat this process one more

time, then set the decanter aside.

PERIODIC CLEANING

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. Pour a decanter of water into the top of the brewer.

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.

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.

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

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.
