52384.1 062217
PLUMBING REQUIREMENTS
This dispenser must be connected to a cold water system with operating pressure between 138 - .620 MPa
(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.
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.
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 plumbing connection is located on the back of the unit, using the water line included with some models, that
connects to a 3/8” male flare.
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 “READY TO BREW
SELECT SIZE”.
PRESET TANK TEMPERATURE
The tank temperatures have been preset at the factory 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.)
