ELECTRICAL REQUIREMENTS
CAUTION - The dispenser must be disconnected from the power source until specified in Electrical Hook-Up.
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.
4. If plumbing is to be hooked up later be sure the dispenser is disconnected from the power source. If
plumbing has been hooked up, the dispenser is ready for Initial Fill & Heat.
CAPACITY
1. Brew chamber has a capacity rating of 5 gm minimum to 15 gm maximum of espresso grind coffee.
2. Brewer has a peak capacity of 60 single (small) espresso shots per hour.
120V
Models 230 VOLT Models
120 & 230 volt ac models
Note: This electrical service consists of 2 current
carrying conductors (L1 and Neutral) and a
separate conductor for chassis ground.

PLUMBING REQUIREMENTS
This dispenser must be connected to a system with operating pressure between 138 - .620 MPacold water
(20 and 90 psi) from a 1⁄2” or larger supply line. A shut-off valve should be installed in the line before the dispenser.
Install a regulator in the line when pressure is greater than .620 MPa (90 psi) to reduce it to .345 MPa (50 psi). The water
inlet fitting is 3/4 British Parallel Pipe.
NOTE - Bunn-O-Matic recommends 6mm copper tubing for installations of less than 25 feet and 8mm for more than 25
feet from the water supply line. 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 counter top. Bunn-O-Matic does not
recommend 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.
NOTE - If a backflow preventer is required by code, a shock arrestor should be installed between backflow preventer and
dispenser. Installing the shock arrestor as close to the dispenser as possible will provide the best results.
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.
PLUMBING HOOK-UP
NOTE: The water inlet fitting is 3/4 British Parallel Pipe.
1. Flush the water line and securely attach it to the valve threads on the rear of the dispenser.
2. Turn on the water supply.
INITIAL FILL & HEAT
1. Turn on the water supply, connect power to the dispenser, and place the main power switch on the rear of the machine
to the ON position.
2. Water will automatically flow into the soluble tank to the proper level, then shut off. This will take less than five
minutes.
3. The screen on the front door will display FILL ESPRSO TANK. Press the button under START.
4. The screen will display MOVING BREW CHAMBER, ESP TANK FILLING, and the espresso tank will begin filling. This
may take several minutes.
5. When water dispenses from the espresso nozzle into the drip tray, press YES under WATER DISPENSED? to stop the
tank filling.
6. The tanks will then begin heating. When the tanks have completed heating, the display will read #############,
SELECT SIZE.
PRESET TANK TEMPERATURE
The tank temperatures have been preset at the factor to 80°C (180°F) for the soluble tank, and 102°C (215°F) for the
espresso tank. Bunn recommends that to provide the best quality beverage, the installer adjust the tank temperature to
the powder product manufacturers recommended temperature for the hot powder product being used.
7. Fill the hopper(s) with the dry product to be dispensed.
8. Fill the bean hopper with the whole beans to be ground and brewed.
LIQUID LEVEL CONTROL
The system automatically maintains the soluble 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, a refill error occurs. When a refill error
occurs, the refill solenoid is de-energized. Once the cause of the refill error has been investigated and cured, the system
can be reset by either cycling the power to the machine (at least five seconds) using the main power switch at the rear of
the machine, or by entering one of the program modes (see Programming Modes.)
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.

Filling Soluble Hoppers
1. Remove packing material from on top of the powder hoppers.
2. Remove powder hoppers by lifting the front of the powder
hopper until the peg on the bottom of the hopper clears the hole in
the mounting plate (see Figure 1). Then pull the hopper forward to
remove.
3. Set the hoppers on the counter, and push the slide gates on the
front of the discharge chutes inward (see Figure 2) to close the
gates.
Figure 1
4. Remove hopper lids and fill the hoppers with appropriate soluble
products. Default menu is milk product left hopper, chocolate is
center hopper, and vanilla is right hopper. Replace hopper lids.
5. Reinstall hoppers back into machine, make sure peg on bottom of
hopper drops into locating hole on hopper platform.
6. After hoppers are installed, discharge chutes must be rotated as
shown in Figure 3.
