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 ¼"
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 ¼"
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).
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.
NOTE: Bunn-O-Matic recommends ¼" copper tubing for
installations of less than 25 feet and 3⁄8" for more than 25
feet from the ½" 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 recom-
mend 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
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.
WARNING
The brewer must be disconnected from the power source until specified in Initial Set-Up. 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.

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 SET-UP (continued)
Bean Hopper Set-up
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
- 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 Set-up - 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.
INITIAL SET-UP (continued)
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 compartments.
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 & 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.

INITIAL SET-UP (continued)
Powder Hopper Set-up
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 posi-
tion. 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.

INITIAL SET-UP (continued)
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 avail-
able 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 3/8inch drill bit, make a hole in the extension
on the back to the drip tray. Then attach a 5/8inch
(inside diameter) hose with a minumum 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.)
