PLUMBING REQUIREMENTS
This dispenser must be connected to a cold water system with operating pressure between 20 and 90 psi (138-
620 kPa) 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 90 psi (620 kPa) to reduce it to 50 psi (345 kPa).
The water inlet fitting is 1⁄4” flare.
NOTE - Bunn-O-Matic recommends 1⁄4” copper tubing for installations of less than 25 feet and 3⁄8” for more
than 25 feet from the 1⁄2” 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
countertop. 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 pre-
venter 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
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.
INITIAL FILL & HEAT
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 ten
minutes. Tanks full of cold water will take approximately fifty minutes for the water to heat on 120 volt ver-
sions, and twenty minutes on 120/240 and 220-240 volt versions.
3. Fill the hopper(s) with the dry product to be dispensed.

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.
LIQUID LEVEL CONTROL
The system automatically maintains the hot and warm water tank’s level by energizing the refill solenoid when
the water level drops below the liquid level probe. If the Hot Tank has not successfully refilled in 10 minutes,
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 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.)
