GENERAL INFORMATION

NOTE -THEBREWER IS NOT READYTO 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 offallelectricalcomponentswhenyourplanstakeyouawayfromhome 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 andallowthewaterinthetanktoheattothepropertemperaturebefore 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 temperatureontheporcelaindecanterwarmer.Thewarmeriscontrolled 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 flip-lidshould 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,groundedcord 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.

P215

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.

COFFEE FUNDAMENTALS

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.

Hot water extracts many elements from the coffee.The amount of coffee used andtheamountofwaterpassedthroughthecoffeedeterminesstrength.Increasing theamountofcoffeeresultsinastrongerbeverage.Decreasingtheamountofcoffee 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 thebeverage.Thishappensbecausethehotwaterbeginstoremovetheundesirable elements after all of the desirable elements have been extracted.

Fresh-groundcoffee 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.

BREWINGTIPS

Whencoffeeisproperlybrewed,thedifferencebetweenthebestqualityground 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-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 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

BU

funnel with a damp cloth.(The brew funnel and decanter

 

are top-rackdishwasher safe.)

 

DELIMING

P2248

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,

P227

 

 

 

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.

 

 

PERIODIC CLEANING

P228

(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

 

drained.Pouradecanterofwaterintothetopofthebrewer.

 

Place the decanter on the warmer, close the lid. Repeat

P204

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

P227

 

into the brewer as needed until the water has no vinegar taste.
