Step 1. Raise the hinged flip-lid (or swivel lid to side if using an NHB). 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 and the post is depressed, the
stopper will be raised and water will flow into the tank.
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, 4 to 6 cups of water will flow through the
funnel and into the decanter.
Step 3. Plug in the brewer.
Step 4. Press the bottom of the vacation
switch, located on the lower left side of the brewer, to the "ON" (lower)

Why is my coffee dripping out very slowly?
The sprayhead may be clogged. Check the round
disk (sprayhead) above the brew funnel. The holes in this part must always
remain open. If they are clogged, remove the sprayhead and clear the holes using
a toothpick.
Always unplug the brewer before deliming or
cleaning the sprayhead. The brewer could be clogged with mineral deposits.
How to delime your brewer
NOTE - Unplug the brewer and let it cool down before deliming.
Step 1. Remove the sprayhead by turning it with
your fingertips and set it aside.
Step 2. Insert all but two (2) inches of the
flexible deliming tool (supplied) into the sprayhead tube.
Step 3. Slide the tool in and out five (5) or
six (6) times to loosen lime in the sprayhead tube. (You may need to twist, push
and use some force when inserting the tool.) Remove the tool.
Step 4. Prior to replacing sprayhead, pour one
decanter of fresh water into the brewer, position the empty decanter on the
brewer, and close the lid.
Step 5. Check the holes of 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, then reinstall.
Step 6. Plug in the brewer and allow the water
in the tank to reheat before using (approximately 15 minutes). NOTE: The
frequency of deliming depends on the mineral content of your water.
Why does my coffee taste weak or bitter?
The taste of your coffee can be caused by all
or any combination of the following:
- Variation in the mineral or chemical content
of the water (For example, high sulfur content water will carry a strong
taste).
- Variation in brands, mixes, quantity, or
quality of coffee.
- Old or improperly stored coffee can easily
taste stale. Coffee should be stored in a clean, dry place away from heat
registers and vents or extreme cold for maximum freshness.
- Size of the coffee grind affects the ability
of the brewer to extract the oils that add flavor to your coffee.
- Missing sprayhead. If the sprayhead is
missing the grounds will not be soaked properly.
- If you have soft water or drink
decaffeinated coffee, you may need a flow restrictor to replace the sprayhead
you are currently using. This will slow down the flow of water, giving you a
stronger flavor of coffee.
Can I pour cold coffee back into the
reservoir to reheat it?
This is not recommended since it can cause
damage to your coffee brewer.
How do I drain my coffee brewer?
Unplug the brewer, place an empty decanter on
the warmer plate and pour cold water through to lower the water temperature.
Wait 15 minutes for brewer to cool.
Remove the glass decanter and filter basket
from the coffee brewer.
Remove the sprayhead (the round disk above the
brew funnel) by turning counterclockwise.
Grasp the brewer and carefully turn it upside
down over a sink. Most of the water in the tank will flow from the sprayhead
opening but some water may flow from the area around the top lid. Continue
tipping the brewer until the flow of water ceases.
Reinstall the sprayhead when all of the water
has drained from the brewer. Securely tighten it by turning clockwise. DO NOT
plug in until you repeat Initial Brewer Set-Up Instructions.
Is it safe to leave my coffee brewer plugged
in at all times?
Yes. This brewer has a specially designed tank
to keep the water at the proper temperature. The constant supply of hot water
assures the correct method of brewing in less than three minutes.
What if I don't plan to use the brewer for
several days?
If you won't be using your brewer for several
days, you can position the main power switch (on the side) to "off". This will
completely shut off the brewer.
Can I purchase an internal replacement part?
For your safety, under UL requirements,
internal parts can only be installed by factory trained personnel. Seals,
gaskets, warmer plates, and warmer plate switches are the only repairable parts.
T
What might cause my coffeemaker to leak?
Leaking can be the result of one or more of the
following causes:
- Improper maintenance or care.
- Normal wear and tear.
- Deterioration of seals or gaskets within
your brewer that naturally occur over time.
- Accumulation of mineral deposits from your
water. Clean your brewer regularly.
I need information regarding warranty,
repair and exchange options.
To obtain more information, call 800-352-BUNN
(2866) to speak with a Customer Support representative. Please be prepared with
the model name of your coffeemaker and the serial number located on the bottom
of your unit.
I live at a high altitude. Can I use a BUNN
brewer?
Yes. BUNN makes models for altitudes of 4,000
ft. and above. The "D" in the model name indicates that it is for high altitude
applications.
How can I brew the best tasting coffee with
my BUNN brewer?
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 tablespoon per cup or
about 1 1/2 inches of coffee in a flat-bottom filter)
- Make sure you use good-tasting water. Check
your water source for softened or hard water. If necessary, run your water
through a water treatment filter.
- Use the correct coffee brewing equipment for
maximum performance. We recommend a quick brew time, using a brewer that keeps
water at 200 Fahrenheit (the ideal temperature) and mixes the grounds for
full flavor extraction.
- Use a thermal carafe if you plan to hold
coffee more than 20-30 minutes. Coffee can be held in a thermal carafe for up
to 60 minutes without losing flavor.
- Make sure to clean your glass decanter every
day.
- Use only quality controlled paper filters
designed to fit your brewing equipment.
- Dispose of filter and grounds immediately
after brewing to prevent drip-through of unwanted flavors trapped in used
coffee grounds.
- Clean your brewing equipment at least once a
week (especially the sprayhead area).
BUNN recommends you DON'T:
- Mix fresh brewed coffee with previously
brewed coffee as this will dilute the taste and affect the flavor of the whole
pot.
- Brew over previously used coffee grounds
because all of the flavor has already been completely extracted.
- Re-heat for serving any coffee with a
temperature below 175F
- Serve coffee brewed with beans or ground
coffee past the freshness date.
- Let coffee "bake" on a brewer. Twenty to 30
minutes is the maximum time allowable for an open pot to deliver a perfect cup
of coffee.
- Serve coffee in pots or decanters that
haven't been properly cleaned, since acids and other organic materials can
taint even the best brewed coffee.
Why does my brewer leak water into the decanter overnight when the lid is
left open?
Our 10-cup brewers (NHB, NHBX, B10, BX, GR10,
GRX, BT10 and BTX) are not designed to hold water in the upper water basin for
an extended period of time, such as overnight.
Can I use the BT/BTX stainless steel carafe
on any BUNN brewer?
No, the stainless steel carafe can only be used
with the BT10/BTX Brewer.
How can I preheat a thermal carafe?
To preheat the thermal carafe, fill the carafe
with hot water for approximately 30 seconds. Empty before brewing coffee into
carafe. Preheating will increase the time your coffee will stay warm.
