SITE REQUIREMENTS
As directed in the International Plumbing Code of the Inter-
national Code Council and the Food Code Manual of the
Food and Drug Administration (FDA), this equipment must
be installed with adequate backflow prevention to comply
with federal, state and local codes. For models installed out-
side the U.S.A., you must comply with the applicable Plumb-
ing /Sanitation Code for your area.
PLUMBING HOOK-UP: The plumbing connections
are located on the bottom of the unit, using a manifold
(included) that connect to a water line using a
1/4 inch connection.
NOTE: Water pipe connections and fixtures
directly connected to a potable water supply
shall be sized,
installed, and
maintained in
accordance with
federal, state,
and local codes.
Counter Requirements
1. Counter able to support at least 200 pounds (90kg).
2. Counter area large enough for machine.
3. Minimum clearance of 2˝ around machine.
4. Machine must be level within 2˚ for proper operation.
Plumbing
1. These brewers must be connected to a cold
water system with operating pressure between
20 and 90 psi (0.138 and 0.620 MPa) from a
1/4 inch or larger supply line. Install a regulator
in the line when pressure is greater than 90 psi
(0.620 MPa) to reduce it to 50 psi (0.345 MPa).
NOTE: Requires a minimum of 1 gallon per
minute flow rate.
2. Shut off valve should be present between water
supply and machine.
3. Flush the water line and securely attach it to the
inlet fitting at the rear of the brewer.
4. Turn on the water supply.
5. Check for leaks.
Location of the Serial Number
The serial number is located on both the data plate
at the rear of the machine, and a decal inside by the
RH powder hopper. The complete serial number will
need to be documented on all work orders and
warranty tags.
WARNINGS
The brewer must be disconnected from the power source until specified in Initial Setup. Refer to Data Plate
on the Brewer, and local/national electrical codes to determine circuit requirements.
Counter Top Installation
1. Remove tape from all five legs.
2. From the parts box, install a 03996.0000 foot
pad on each leg.
NOTE: For through counter grounds disposal,
the rubber feet must be installed on the bottom
of the legs to ensure alignment between the
ground chute and counter top opening.
Tape (remove)
Install Foot Pads
Tape (remove)
INITIAL SETUP
• Unplug the machine or turn off the main switch before servicing the interior components of the machine.
• Never operate the machine without water.
• Never touch brew module, spouts, and hot water dispense pipes. They are HOT and could cause burns.
• The machine must be operated with clean water. Make sure to use water filters and/or softeners as needed.
NOTE: Bunn-O-Matic recommends ¼" copper
tubing for installations of less than 25 feet and
3⁄8 inch for more than 25 feet from the ½ inch water
supply line. A tight coil of copper tubing in the water
line will facilitate moving the brewer to clean the
counter top. Bunn-O-Matic does not recommend
the use of a saddle valve to install the brewer. The
size and shape of the hole made in the supply line
by this type of device may restrict water flow.
Water Treatment
1. No Chlorine, no chloramines
2. Water Hardness 6 to 10 grains (total hardness)
3. Water Filtration System

Electrical Hook-Up
CAUTION
Improper electrical installation will damage
electronic components.
1. An electrician must provide electrical service
as specified.
2. Using a voltmeter, check the voltage and
color coding of each conductor at the
electrical source.
3. Connect the dispenser to the power source
(plug it in).
4. Locate the switch at the rear of the machine and
flip the power switch to the "ON" position
NOTE: The boot-up sequence may take
60-90 seconds, and the machine will cycle in
preparation for operation. The door must be
closed, or the door interlock engaged at
power up.
5. If plumbing has been hooked up, the dispenser
will auto-fill and heat.
6. After the boot-up sequence is complete, open
the door and remove the cardboard shipping
pad from the top of the brew box.

INITIAL SETUP
Bean Hopper Setup
1. Remove the bean hopper from the packaging;
taped to the lid is the lid lock key - DO NOT
LOSE THIS KEY. When not being used, keep
the lid key in a secure place. The hopper is
divided into three compartments with a lockable
lid.
NOTE: DO NOT FILL hoppers prior to installing
because the weight of a filled hopper makes
installing it difficult.
2. Prior to installing the bean hopper, visually
verify that there are no obstructions or debris
blocking the bean hopper location and bean
detection sensors.
3. Close the bean hopper chutes by sliding the
hopper lock mechanism (Red Ball) to the right
as shown. This will allow the bean hopper to
properly locate once installed.
NOTE: This must be done to remove the hopper
and also prevent any beans from spilling from
the hopper.

Bean Hopper Setup (continued)
4. Install the Bean Hopper into the machine as
shown. Some minor movement may be required
to settle the hopper into its proper seating.
6. Insert Hopper Lid Key into key hole located on
the left side of the Bean Hopper Lid as shown.
Once the lid is unlocked, lift the lid, and you
have access to each of the three bean compart-
ments.
NOTE: At this point, go ahead and fill each of the
hoppers with the beans that make up your
unique recipes. Close the lids, and then close
and lock the main hopper lid.
5. Lock the Bean Hopper into place by pushing the
hopper lock mechanism (Red Ball) to the left as
shown. Doing this will slide a metal tang into a
slot, thus preventing the bean hopper from
being removed as well as allowing the beans to
flow from the hoppers when the bean augers are
engaged. Failure to do so may result in improper
machine performance or damage to the hopper.

Powder Hopper Setup
1. Remove the powder hoppers from the
packaging. Before filling each with the
appropriate product, verify that the auger
spring is in it's correct position. If the auger
spring is not engaged, rotate the auger
driveshaft clockwise till the auger spring is
fully seated as shown.
2. Before installing the powder hoppers, take note,
that at the rear of each hopper is a cavity that
corresponds with a locating block in each of the
powder hopper locations. When a hopper is
placed in position, the locating block fits into
the cavity, thus ensuring proper powder hopper
placement. Also, the front of the hopper needs
to be placed behind the retaining tab directly
behind the whipper mixing bowl.
3. Fill the hoppers, then install one on either side of
the machine as shown.

3. Position the drip tray as shown. When properly
placed, the drip tray fits up against the front legs
of the machine.
Waste Bin / Drip Tray
1. Remove the waste bin from the packaging, and
install as shown. A magnet is located on the
back of the bin.
NOTE: An optional through counter waste bin is
available for unattended sites.
2. Unpack the drip tray/cover. Remove the tape
securing the cover.
If setting up to have drip tray drain through
a counter, a hose will need to be attached.
Using a 3/8 inch drill bit, make a hole in the
extension on the back to the drip tray. Then
attach a 5/8 inch (inside diameter) hose with
a minimum rating of 200˚F. The hose needs
to flow downhill to work properly.
Suggested set-up if draining drip
tray through a counter.
3/8" hole drilled in extension, 5/8" hose
attached, and a 90˚ elbow connector to
ensure liquid flows downhill.
