PLUMBING REQUIREMENTS
This dispenser must be connected to a cold water system with operating pressure between 20 and 90 psi (138
and 620 kPa) from a 1/2˝ or larger supply line. A shut-off valve should be installed in the line before the brewer.
Install a regulator in the line when pressure is greater than 90 psi (620 kPa) to reduce it to 50 psi (345 kPa). The
water inlet fitting is .75-11.5 NH (HOSE THREAD). For convenience an elbow adaptor is provided to convert to
a 1/4˝ flare fitting. Bunn-O-Matic does not recommend the use of a reverse-osmosis or deionized water supply
to this equipment. REQUIRED: 1.0 gpm (3.78 lpm) flow rate from water supply line.
NOTE - At least 18 inches of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene
or silicone, before the dispenser will facilitate movement to clean the countertop. Bunn-O-Matic does not recom-
mend the use of a saddle valve to install the dispenser. The size and shape of the hole made in the supply line
by this type of device may restrict water flow.
As directed in the International Plumbing Code of the International 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 outside the
U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.
PLUMBING HOOk-UP (Early Models)
1. Securely attach the short piece of tubing on the water strainer assembly to the inlet fitting on the bottom of
the dispenser.
2. Flush the water line and securely attach it to the flare fitting on the water strainer assembly.
3. Turn-on the water supply.
PLUMBING HOOk-UP (Late Models)
1. Flush the water line and securely attach it to the elbow fitting on the bottom of the dispenser.
2. Turn-on the water supply.
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.
INITIAL FILL & HEAT
CAUTION - The dispenser must be disconnected from the power source throughout the initial fill & heat, except
when specified in the instructions.
1. Turn on the water supply and connect the dispenser to the power source.
2. Water will automatically flow into the tank to the proper level and then shut-off. This will take less than five
minutes.
3. When the tank is full of water, open the front door and place the heater switch in the “ON” (lower) position.
A tank full of cold water will take approximately forty minutes for the water to heat on 120 volt versions, and
twenty minutes on 120/240, and 220-240 volt versions.
During this waiting period, complete these dispenser set-up steps:
a. Place a set of keyholes in the splash panel over the screws beneath the hopper access door and push down
gently.
b. Place the drip tray onto the supports on the splash panel. Hook the tabs on the rear of the drip tray through
the holes in the splash panel. Set the drip tray cover in place.
c. Fill the hopper(s) with the dry product to be dispensed.
PRESET TANk TEMPERATURE
Tank temperatures have been preset at the factory to 180°F (82°C). Bunn recommends that to provide the best
quality beverage, the installer adjust the tank temperature to the powder product manufacturer’s recommended
temperature for the hot powder product being used.

LIQUID LEVEL CONTROL
The system automatically maintains the hot water tank’s level by energizing the refill solenoid when the water
level drops below the liquid level probe. If the system has not successfully refilled in 15 minutes, a refill error
occurs.
When a refill error occurs, the refill solenoid is de-energized and the 3 position L.E.D.’s will flash sequentially;
left...center...right...left...center...right...etc.
Once the cause of the refill error has been investigated (see the troubleshooting guide) and cured, the system
can be reset by either disconnecting (for at least 5 seconds) and then reconnecting the power to the machine,
or by entering one of the program modes (see Programming Modes.)
RINSE TIMER
The dispenser is shipped from the factory with the rinse timer disabled. To enable the rinse timer, remove power
from the dispenser, remove the lower access panel, and remove the jumper from J4 of the control board. For
dispensers with hot water dispense, remove power from the dispenser, remove the lower access panel, and dis-
connect the green wires coming from J4 of the control board from each other. Replace the lower access panel,
and return power to the dispenser.
When enabled, the rinse timer automatically keeps track of the time since the dispenser was last run through
a rinse sequence. If the dispenser detects that a rinse sequence has not been run for 8 hours, all three position
L.E.D.’s will flash continually. If, after an additional 4 hours (12 hours total), a rinse cycle has still not been run,
all three position L.E.D.’s will light continuously, and the hopper drives will be disabled until a rinse sequence
has been run.
RUNNING A RINSE SEQUENCE
1. Place the Rinse/Run switch in the “rinse” position .
2. Sequentially or simultaneously at each of the three positions, press any of the three dispense switches. The
dispenser will run for 10 seconds with the hopper(s) disabled.
3. As each position is rinsed, the corresponding L.E.D. will extinguish, indicating that the rinse cycle took
place.
4. After all three position L.E.D.’s have extinguished, the rinse timer is reset.
5. Return the Rinse/Run switch to the “run” position.
DISPENSER USE
1. Simply place a cup on the drip tray beneath the desired dispensing tip.
2. a) Momentarily press the appropriate dispense switch to froth and dispense the beverage. The dispenser will
automatically dispense the beverage for the programmed dispense time at the programmed hopper dispense
rate. The dispenser is factory preset to produce the approximate dispense sizes as follows:
Small (8 seconds): approximately 8 fluid ounces of beverage.
Medium (12 seconds): approximately 12 fluid ounces of beverage.
Large (16 seconds): approximately 16 fluid ounces of beverage.
To stop a timed dispense, press the stop switch or any of the switches on the position that is running.
Note - The mixing chamber must drain at the end of each dispense.
The dispense times can be individually programmed by following the procedures described in Programming
Modes.
b) Hot Water - Push and hold the hot water switch until the water reaches the desired level, then release.

HOPPER DISPENSE RATE OF PRODUCT
The hopper dispense rates are preset at the factory. With 22 tooth gear and auger wire, the preset dispense
rate is approximately 3 to 5 grams per second. With 30 tooth gear and auger wire, the preset dispense rate is
approximately 5 to 7 grams per second. The hopper dispense rates can be individually programmed to a range
of dispense rates from approximately 1.5 to 12 grams per second by following the procedures described in
Programming Modes.
PROGRAMMING MODES
1. Enter / Exit:
a. To enter the program mode, press any two dispense size switches, on the position to be programmed, at the
same time. The L.E.D. will flash indicating the program mode.
b. To exit the program mode, press a switch on any position other than the one being programmed.
Note: The stop switch will not cause exit of program mode since it is used for some programming operations.
If in the program mode for more than 25 seconds and no switches have been pressed, the program mode is
automatically exited.
2. Dispense Run Time:
a. Enter the program mode on the position you want to program (see step 1.a.)
b. Place the “Rinse/Run” switch in the “Run” position and press and hold the cup size to be programmed.
c. When the desired amount is reached, release the switch, the time is recorded in memory.
To set the time to non-timed dispense, just momentarily press the position switch. This actually sets in a very
short timed dispense.
d. Repeat for remaining cup sizes if desired.
e. Exit the programming mode (see step 1.b.)
3. Increasing / Decreasing the Hopper Dispense Rate:
a. Enter the program mode on the position you want to program (see step 1.a.)
b. Place the Rinse/Run switch in the “Rinse” position.
c. Press and hold down on the stop switch and press the small switch to decrease the dispense rate or press
the large switch to increase the dispense rate. Each time the button is pressed, the dispense rate will increase/
decrease by approximately 21/2 %. Each time the small or large switch is pressed, the L.E.D. on that position
will flash on and off to indicate the switch was recognized. When the maximum or minimum level is reached
all 3 position L.E.D.’s will flash rapidly.
d. To return the dispense rate to the factory preset, press and hold down stop switch and press the medium
switch. When the medium switch is pressed, the L.E.D. on that position will flash on and off to indicate the
switch was recognized.
e. Return the Rinse/Run switch to the “Run” position.
f. Exit the programming mode (see step 1.b.)
4. Making Common Timed Dispenses: Once a position has been programmed to the proper dispense times,
you can make all 3 positions the same, as follows:
a. Place the Rinse/Run switch in the “Run” position.
b. Enter the program mode on the position you want all others to be like (see step 1.a.)
c. Press and hold the Stop switch for 10 seconds.
d. After the 10 second period, all 3 position L.E.D.’s will come on solid indicating the task is complete. The
program mode is exited when the Stop switch is released.

5. Running Hopper Throw Test: The hopper throw can be checked by automatically running the hopper motor
as follows:
a. Remove the steam collector and mixing chamber from under the hopper to be checked.
b. Position a small cup under the hopper outlet.
c. Enter the program mode on the position you want to check (see step 1.a.)
d. Place the Rinse/Run switch in the “Run” position.
e. Press and hold the stop switch down and press the small, medium, or large switch. The hopper will run for
the programmed timed dispense period at the programmed dispense rate.
f. Remove the cup and weigh the dispensed product.
g. Exit the programming mode (see step 1.b.)
h. Replace the mixing chamber and steam collector.
6. Making Common Dispense Rates: Once a position has been programmed to the proper hopper dispense rate,
you can make all 3 positions approximately the same, as follows:
a. Place the Rinse/Run switch in the “Rinse” position.
b. Enter the program mode on the position you want all others to be like (see step 1.a.)
c. Press and hold the Stop switch for 10 seconds.
d. After the 10 second period, all 3 position L.E.D.’s will come on solid indicating the task is complete. The
program mode is exited when the Stop switch is released.
e. Return the Rinse/Run switch to the “Run” position.
7. Password: The password is to be used to prevent unauthorized entering of the program modes. The password
is preset at the factory to 0 (no password.)
a. To enter the password programming, press and hold any two dispense size switches on any one of the posi-
tions for 10 seconds. All 3 position L.E.D.’s will begin flashing indicating that the dispenser is ready to accept
a new password.
b. When the switches are released the 3 L.E.D.’s will stop flashing. At this time press the Stop switch the num-
ber of times that is the password (For example: If you press the Stop switch 5 times, you will then have to
press the Stop switch 5 times before you will be able to enter the program mode the next time.)
c. 5 seconds after the Stop switch is pressed for the last time, the password is recorded in memory. As a
verification of the password, when the 5 seconds is up, the 3 L.E.D.’s will flash the password. (For example:
If the password is 5, when the exit of the password occurs, the L.E.D. will flash 5 times.)
d. Thereafter, the Stop switch needs to be pressed the password number of times before the program mode
can be entered.
NOTE: After 5 seconds of pressing the Stop switch for the final time, the password counter is reset to 0. So if
the password is mis-entered, wait 5 seconds before trying again.
e. To reset the password to 0 (no password,) enter the old password, then press and hold any two dispense
size switches on any one of the positions for 10 seconds. All 3 position L.E.D.’s will begin flashing indicating
that the dispenser is ready to accept a new password. Then just wait 5 seconds without pressing the Stop
switch.
NOTE: There will be no indication when the 5 seconds are up and the password is reset to 0.
