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. 1 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). 2 GENERAL INFORMATION 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. · 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 50°F hotter than what's 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. HOT WATER Get hot water anytime. Just leave out the paper filter and coffee from the brew funnel. With funnel in place, pour cold water into brewer and in just minutes you will have hot water. 3 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. F OF OF F O N 10 8 10 6 4 BUN N 8 6 4 BUN N 6.

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 200°F. 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 Customer Service at 800-352-2866 to order a flow restrictor BUNN sprayhead free of charge. For cup of coffee, grind fresh beans just before brewing. Adjust the best the of coffee to suit your individual taste. amount 6 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 heaping tablespoon per cup or about 1½ 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 ...
