WARNING

RISK OF FIRE OR ELECTRICAL SHOCK
WARNING, TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK DO NOT DISASSEMBLE THE BREWER NO USER-SERVICEABLE PARTS INSIDE REPAIR SHOULD BE DONE BY AUTHORIZED SERVICE PERSONNEL ONLY
This symbol alerts you to important operating and service instructions.
This symbol alerts you to the risk of fire or electrical shock in the accompanying message.

IMPORTANT SAFEGUARDS

Follow these basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and/or personal injury: Read all instructions. Do not touch hot surfaces. Use handles. Do not place cord, plugs, or brewer in water or liquid. Close supervision is necessary when the brewer is used by or near children. Unplug from outlet when not in use for extended periods of time and before cleaning. Allow to cool before putting on or taking off parts, and before cleaning. Do not operate the brewer with a damaged cord or plug or if the brewer malfunctions or is damaged in any manner. Return the brewer to an Authorized Service Facility for examination, adjustment, or repair. (Refer to page 10.) Using an accessory not evaluated for use with this brewer may cause injuries. For household use only. Do not use outdoors. Do not let cord hang over edge of table or counter or touch hot surfaces. Do not place the brewer on or near a hot gas or electric burner or in a heated oven. Do not use brewer for any other purpose than its intended use. Do not place or remove funnel or decanter while brewing. Do not use the decanter on a range top or in a microwave. Do not set a hot decanter on a cold surface. Do not use a cracked decanter or a decanter with a loose or weakened handle. Do not pour liquids into the water tank other than water or vinegar solution for cleaning, as specified in this manual. Do not clean decanter with cleansers, steel wool pads, or other abrasive materials. When the brewer is idle, the lid should be in the closed position.

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 the edge of table or counter where it can be pulled on by children or tripped over. The extension cord must be a three-wire cord of the three-pronged, three-socketed, grounding type (including grounding conductor).

Improper set up will result in permanent damage and void the limited warranty. Read and follow the initial set up instructions on page 4. This brewer is designed to remain plugged in at all times, except during initial set up or when cleaning. A vacation switch is provided on the lower side to completely shut off all electrical components when your plans take you away from home for three or more days. Safety features that are designed into the BUNN coffee brewer make the daily use of this switch unnecessary. Press I to turn on and press O to turn off. If the brewer has been shut off or unplugged for an extended period of time, fill the tank with water and allow the water in the tank to heat to the proper temperature before using (about 15 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. (BTX models) The brewed coffee flows into an unheated thermal carafe. The double wall stainless steel construction will hold coffee at serving temperature for about two hours at maximum flavor. Pre-heating with hot water will increase the time your coffee stays warm. (GRX, BX and NHBX models) The brewed coffee flows into a glass 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. The decanter lid reduces coffee evaporation and temperature loss. 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 lid should be closed. If the lid is left open, water could drip from the sprayhead when cold water is poured in. Use CAUTION when dispensing hot water from the brewer. The water is approximately 50F hotter than whats available from your hot water faucet and is always available for other uses. The sprayhead may periodically become loose. Using extreme caution since it may be hot, retighten the sprayhead with your fingertips. NOTE: A severe burn may result if the sprayhead becomes loose and falls off while the coffee is brewing.

GENERAL INFORMATION

HOT WATER
Get hot water anytime. Just leave out the paper filter and i coffee from the brew funnel. With funnel in place, pour cold no water into brewer and in just minutes you will have hot water.

Initial Set Up Guide

IMPORTANT: Brewer is NOT ready to plug in until you have followed the steps below. Do NOT plug in brewer until step #5. NHBX 1. Slide empty funnel into funnel guides as shown. BTX/BX/GRX
2. Fill decanter with cold water. Swivel or lift brewer lid and pour water into brewer. Position decanter on base below funnel. Close the lid and wait three minutes while the internal tank partially fills.
3. Open the lid. Remove decanter and fill with cold water again. Pour water into brewer. Position decanter on base under funnel and close the lid. 4. Wait until water flows from the funnel. When water flow stops, pour out any water that has collected in the decanter. Replace decanter on brewer below the funnel. 5. Now, plug in the brewer.
6. Press the bottom of the vacation switch, located on the side of the brewer, to turn unit on (Press I to turn on and press O to turn off.) Wait 15 minutes for the water in the tank to heat. See steps on page 5 for brewing perfect coffee.

Brewing Perfect Coffee

See page 4 for initial set up before brewing the first time. 1. Insert BUNN coffee filter into the brew funnel. 2. Measure fresh coffee into the filter and shake gently to level the bed of grounds. (We recommend 1-2 heaping Tbsps. of drip grind per cup of coffee). 3. Slide the brew funnel into funnel guides and open lid. 4. Pour in cold water; minimum 4 cups (20 oz), up to maximum 10 cups (50 oz) Do not close the lid without the funnel and decanter in place. Closing the lid releases the hot water. 5. Position decanter in place on base under funnel of brewer. (With BTX, pre-heat carafe with hot water) 6. Turn on the warmer. (not applicable with BTX ThermoFresh brewer) 7. Close the lid to start the flow of water into the tank.
8. When brewing has stopped, remove the brew funnel and discard the filter and grounds. Do not touch hot grounds.

Better Brewing

BUNN home brewers are made to do exactly what BUNN commercial brewers do: produce great tasting coffee - quickly, simply and consistently. Cup after flavorful cup, year after year, nothing brews like a BUNN.
The Patented BUNN Brewing Difference
Perfect coffee flavor is robust without bitterness and is determined by three elements: water temperature, the time ground coffee is exposed to the water and how much of the coffee is exposed to the water. TEMPERATURE The patented ready-to-brew reservoir keeps water at the ideal brewing temperature of approximately 200F. TIME The fast 3-minute cycle is the perfect brew cycle time for the most coffee flavor without bitterness. Brew cycles that expose ground coffee for more than 6 minutes cause an overextracted, bitter taste. TURBULENCE The unique sprayhead design creates the right amount of turbulence to suspend ground coffee and extract flavor evenly and thoroughly. With most coffee makers, water drips straight through without evenly exposing all coffee granules to the water.

Use of decaffeinated, fine grind coffee and/or softened water may cause an overflow of grounds into your decanter. Visit www.bunn.com or call D i d y ou kn w BUNN Customer Service at 800-352-2866 to order a flow restrictor sprayhead free of charge.
ForU s t best cup of coffee, grind fresh beans just before brewing. Adjust the e d d y ou thek n o w of coffee to suit your individual taste. amount

BUNN recommends you DO:

Keep coffee stored in a clean, dry place away from heat registers and vents or extreme cold for maximum freshness. Use enough coffee (one to two heaping tablespoons per cup or about 1 inches of coffee in a flat-bottom filter.) Use a thermal carafe if you plan to hold coffee more than 20-30 minutes. Coffee can be held in a glass decanter for up to 30 minutes or a thermal carafe for about two hours. Make sure to clean your decanter every day. Pre-heat the thermal carafe with hot water for best results. Use only BUNN paper filters for proper fit and function. Using a shorter filter may result in overflow. Dispose of filter and grounds immediately after brewing to prevent drip-through of unwanted flavors trapped in used coffee grounds. Clean your BUNN brewer with mild, dish soap and water at least once a week, especially the sprayhead area. (Do not use any soap or cleaner with citrus added).

? ? ? ? ?

Fresh, good-tasting water is essential for a perfect cup of coffee. After all, ove 98% of the beverage is water. If your water contains excessive amounts of sediment, taste or odors, we recommend k o installing a water conditioner and requesting a flow restrictor sprayhead.
BUNN recommends you AVOID:
Mixing fresh brewed coffee with previously brewed coffee. a
o s S Brewing over prevb a u ed coffee grounds - all the flavor has already been S a ously a e s completely extU s t e acted s e Re-heating for serving any coffee with a temperature below 175F.
Serving coffee brewed with beans or ground coffee past the freshness date. Letting coffee bake on a brewer warmer. Twenty to 30 minutes is the maximum u time allowable Vo an open decanter to deliver a perfect cup of coffee. for s Serving coffeeavez su in decanters that havent been properly cleaned, since acids and su other organic materials can taint even the best coffee.
Youra b S BUNN brewer is designed to remain plugged in at all times, D except wd initial set up, when cleaning or if it will not be in use for Un o during ste three or more days.

CLEANING INSTRUCTIONS

Daily washing and cleaning of the brew funnel and decanter after each use is required. Occasionally, wipe the outside of the brewer, including the area above the funnel, with mild, no citrus added dish soap and a damp cloth. The brew funnel and decanter are top rack dishwasher safe. Please see page 9 for instructions on cleaning your thermal carafe. DELIMING You should delime your BUNN brewer to clear any deposits that may have accumulated due to impurities in the water source. The frequency of deliming depends on the mineral content of your water. NOTE - Unplug the brewer and let it cool down before deliming. 1. Remove the sprayhead by turning with your fingertips and set it aside. 2. Insert all but two inches of the flexible deliming tool (supplied) into the sprayhead tube. Call 800-352-2866 or visit www.bunn.com for a replacement deliming tool. 3. Slide the tool in and out five or six times to loosen lime in the sprayhead tube. You may need to twist, push and use some force when inserting the tool, then remove. 4. Prior to replacing sprayhead, pour one decanter of fresh water into the brewer. Position empty decanter on the brewer and close the lid. Water will flow into decanter. 5. Check the holes of the sprayhead. If plugged with mineral deposits or white flakes, they may be cleared by using a toothpick. Clean the sprayhead with a cloth and mild detergent. Rinse the sprayhead with water, then reinstall. Empty water from decanter. 6. Plug in the brewer and allow the water in the tank to reheat before using (approximately 15 minutes). PERIODIC CLEANING You should clean your BUNN brewer at least every 3 months. The frequency of cleaning depends on the mineral content of your water. 1. Slide an empty brew funnel into the brewer under the sprayhead and center an empty decanter on the base plate. 2. Open the lid and pour one quart of white vinegar into the top of the brewer; close the lid. Empty the decanter when liquid stops flowing from the funnel. 3. Allow the brewer to sit plugged in for two hours. 4. Unplug the brewer. Remove the brew funnel and sprayhead from the brewer. 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. With funnel in place, position decanter on base plate, 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 base plate and close the lid. When water has stopped flowing from the brewer, empty the decanter. Repeat this process and set the decanter aside. 7. Grasp the back of the brewer and turn it upside down over a sink. 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. Pour a decanter of water into the top of the brewer. Place the decanter on the base plate; close the lid and wait 3 minutes. Repeat this process with another decanter of water. Water will flow out of the funnel after the second decanter has been poured in. 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 base plate and close lid. 9. Replace the sprayhead and funnel. Pour additional decanters of fresh, cold water into the brewer as needed until the water has no vinegar taste. 10. Place decanter on base plate and plug in the brewer. Allow the water in the tank to reach brewing temperature before using (approximately 15 minutes).
