Bunn S/N 0005473 & UP manual Plumbing Requirements, Plumbing Hookup

PLUMBING REQUIREMENTS

This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 100 psi (138 and 690 kPa). This water source must be capable of producing a minimum flow rate of 3 fluid ounces (88.7 milliliters) per second. A shut off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). Also if the install location experiences pressure fluctuations greater than 20 psi (138kPa). The main water inlet is a 3/8” (9.52 mm) male flare.

Additionally, the dispenser’s rinse connection may be connected to a HOT WATER system.

Caution: MAXIMUM RINSE WATER TEMPERATURE: 170 degrees F (76.6 degrees C)

Use BUNN-O-MATIC tubing, part number 34325.10_ _ (see Illustrated Parts Catalog for complete part number) for hot water connection.

The rinse water operating pressure must be between 20 and 100 psi (138 and 690 kPa). A shut off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). The rinse water inlet is a 3/8” (9.52 mm) barb connection.

NOTE- At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene, before the dispenser will facilitate movement to clean the countertop. It can be purchased direct from BUNN-O-MATIC (part number 34325.10_ _ [see Illustrated Parts Catalog for complete part number.]) BUNN-O-MATIC does not recommend the use of saddle valves to install the dispenser. The size and shape of the hole(s) made in the supply line(s) by saddle valves may restrict water flow.

NOTE- On early models dispensers without water inlet valve, a water strainer (Bunn-O-Matic part number 23720.1000) should be installed in line, prior to the flexible water line. This strainer is supplied loose with the dispenser.

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.

This equipment must be installed to comply with the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA). For models installed outside the U.S.A., you must comply with the applicable Plumbing/Sanitation Code for your area.

PLUMBING HOOKUP

CAUTION: The dispenser must be disconnected from the power source throughout the plumbing hookup.

For early models without the water inlet valve, plumbing connections are located behind the dispenser’s splash panel. Hoses are connected to the water valve(s) and travel under the water bath tank and out the rear of the dispenser. A .38" female flare connector is attached to the hose and connects to the supplied water strainer. The water strainer is shipped loose, taped to the bottom panel.

For late models with the water inlet valve, a hose assembly from the water bath shut-off valve travels over the top of the water bath tank to the product coil and the water inlet valve. A .75" hose to .38" male flare fitting attaches to the water inlet valve.
