Welcome to Phase Brew!
You’re about to start brewing better coffee in a whole new way! The BUNN Phase Brew
with Heat & Release Technology is different from any coffee maker you’ve used before.
Unlike typical drip machines, BUNN Phase Brew doesn’t ‘drip’ right away. In fact, it doesn’t
drip at all – it flows.
Phase Brew heats all the water to the right brewing temperature, then quickly
releases it through our unique sprayhead for an optimal 4-minute brewing phase and
amazing coffee flavor in just 10 minutes!
THE BUNN PHASE BREW EXPERIENCE
the 6-minute heating phase
When you fill the brew funnel with coffee grounds, the top tank with
water, and press the On/Off button, coffee won’t flow into the carafe
right away – even though the 6-minute heating phase has begun.
What you’ll hear: After a few minutes, you’ll hear some bubbling
and rumbling sounds, which are perfectly normal. It’s the sound of
our Cyclonic Heating System™ bringing the water to about 200°F –
the right temperature to brew without bitterness.
What you’ll see: As you look at the control panel, you’ll see
“Heating Water” and a moving ‘racetrack’. This tells you you’re in
the heating phase.
*
the release
When all the water reaches the optimal brewing temperature, it’s
released from the top tank to our unique sprayhead – beginning the
optimal 4-minute brewing phase.
What you’ll hear: During the release, you’ll hear a ‘whoosh’ of
water to our unique sprayhead.
What you’ll see: As water is released to the sprayhead, the top
tank empties and the heating element creates steam. Most of the
steam is channeled back into the brew funnel, but some escapes
through the top of the brewer.
the 4-minute brewing phase
Following the 6-minute heating phase and release, the 4-minute
brewing phase begins!
What you’ll see: Rich coffee leaving the brew funnel and flowing
into the carafe.
What you’ll smell: Amazing coffee aroma!
10 MINUTES TO PERFECT COFFEE!
*Length of heating phase is affected by the temperature of water
poured into the brewer and the room’s temperature.

IMPORTANT SAFEGUARDS
Follow 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 other liquids.
• Do not open lid during heating or
brewing phases.
• Close supervision is necessary when
brewer is used by or around children.
• Let brewer cool before removing or
replacing parts, and before cleaning.
• Do not operate brewer with a damaged
cord or plug or if the brewer malfunctions
or is damaged in any way. Return brewer
to an authorized service center for
examination, adjustment, or repair (see
page 7).
• Using an accessory not evaluated for use
with this brewer may cause injury.
• Do not place brewer on or near a hot gas
or electric burner or in a heated oven.
• Do not use brewer for any purpose other
than its intended use.
• Do not remove brew funnel or carafe
while brewing.
• Do not use carafe on a range top or in
a microwave.
• Do not set a hot carafe on a cold surface.
• Do not use a cracked carafe or a carafe
with a loose or weakened handle.
• Do not pour any liquid into the water tank
other than water or vinegar for cleaning,
as specified in this manual.
• Do not clean carafe with cleansers, steel
wool pads, or other abrasive materials.
• When brewer is not in use, keep lid in the
closed position.
• For indoor household use only.
• Do not let cord hang over edge of table
or counter or touch hot surfaces.
note: The short power-supply cord supplied reduces the risk of becoming entangled in or tripping
over a longer cord. If an extension cord is used, its marked electrical rating must be at least as great
as the electrical rating of the brewer. Make sure the extension cord does not hang over the edge of a
table or counter and that it cannot be pulled on by children or tripped over. The extension cord must
be a 3-wire cord of the 3-prong, 3-socketed, grounding type (including grounding conductor).

WHY BUNN BREWS BETTER
PHASE BREW VS. TYPICAL DRIP
BUNN Phase Brew is different from any brewer you’ve used before. Unlike ordinary coffee
makers, BUNN Phase Brew doesn’t ‘drip’ right away. In fact, it doesn’t drip at all. That’s
because BUNN Heat & Release Technology heats all the water to the right temperature,
then quickly releases it through our unique sprayhead for an optimal 4-minute brewing
phase and amazing coffee flavor in just 10 minutes!
