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).

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. 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  
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.

the first time.  
NHBX  
BTX/BX/GRX  
1. Insert BUNNcoffee 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

6. Turn on the warmer. (not applicable  
with BTXThermoFresh 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.  
To pre-heat the thermal carafe, fill with hot water for approximately  
30 seconds. Empty before brewing coffee into carafe.

BUNN filters are unique. Made with a special grade of paper for  
best coffee f avor, our filters are designed for strength, so the  
sides are taller and you don’t end up with overflow and grounds  
in your coffee.

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 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  
BUNN Customer Service at 800-352-2866 to order a flow restrictor  
?
sprayhead free of charge.  
For the best cup of coffee, grind fresh beans just before brewing. Adjust  
the amount of coffee to suit your individual taste.  
?

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 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 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  
installing a water conditioner and requesting a flow restrictor  
sprayhead.  
?
Your BUNN brewer is designed to remain plugged in at all times,  
except during initial set up, when cleaning or if it will not be in use for  
three or more days.  
?
BUNN recommends you AVOID:  
Mixing fresh brewed coffee with previously brewed coffee.  
Brewing over prev ously u ed coffee grounds - all the flavor has already been  
completely ext acted  
Re-heating for serving any coffee with a temperature below 175°F.  
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  
time allowable for an open decanter to deliver a perfect cup of coffee.  
Serving coffee in decanters that haven’t been properly cleaned, since acids and  
other organic materials can taint even the best coffee.

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  
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.  
8
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).  
While cleaning your brewer, don’t forget to check your glass decanter  
handle. If loose, use a standard screwdriver to tighten.

brew through valve  
THERMAL CARAFE ROUTINE CLEANING (BTX MODEL)  
The carafe may be disassembled for cleaning. Rotate the lid  
counterclockwise to remove. Occasionally, the brew through valve  
should be removed and cleaned. Lift at the edge and pull up. Use  
a mild, non-abrasive detergent to wash the lid thoroughly paying  
particular attention to the passage where the brew through valve is located. After rinsing,  
replace the brew through valve into the carafe lid. Do not use a scrub pad or other abrasive  
cleaning device to clean the caraf , as this will scratch the stainless steel surface.  
To remove coffee stains from inside the thermal carafe, place a paper filter in the funnel  
and pour in two teaspoons of Cascadepowder dishwasher detergent into the paper  
filter. Slide funnel onto the rails and open brewer lid. Pour one carafe of cold water  
into brewer. Position carafe on base plate of brewer and close lid. When brewing cycle  
has stopped, remove the brew funnel and discard the filter and detergent; rinse funnel  
thoroughly. Allow carafe to sit for 10-15 minutes. Using a long handled, soft bristled  
brush, clean inside of carafe as well as the outer rim to remove any coffee stains or  
debris. Occasionally scrub the carafe pour lip and the area around it, including the lid,  
with a mild detergent and warm water. Use a soft cloth and scrub hard. When finished,  
pour out solution into sink and thoroughly rinse carafe and lid with clean water.

DRAININGYOUR BREWER  
The water in your BUNN coffee brewer should be emptied whenever it is taken on a trip,  
shipped, stored in an unheated location with a chance of freezing, or goes unused for a  
extended period of time. To drain your brewer, use the following procudure:  
1. Unplug the brewer. Remove the brew funnel and sprayhead from the brewer and set  
them aside.  
2. 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.  
3. Grasp the back of the brewer and carefully 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.  
4. Replace the sprayhead and funnel after the water has been drained.
