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 to completely shut-off all electrical components when
you’ll be away from home for three or more days. Safety features that are designed
in the BUNN coffee brewer make daily use of this switch unnecessary. On the NHBX,
the switch is on the lower right side (when you’re facing the brewer). Press I to turn
on and O to turn off. On the STX, it is on the lower back of the brewer. To turn it on,
press in the top of the switch (I) and to turn off press in the bottom (O). The red power
light on the right front of the STX trunk will be illuminated when the power is on.

• 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 hot water tank to keep the
water at the proper temperature. This constant supply of hot water assures correctly
brewed coffee.

• (STX model) 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.

• (NHBX model) 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.
