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). The
main water inlet is a 3/8” (9.52 mm) barb connection.
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 32759.10_ _ (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 or silicone, before the dispenser will facilitate movement to clean the countertop. It can
be purchased direct from BUNN-O-MATIC (part number 32759.10_ _ [see Illustrated Parts Catalog for com-
plete 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- A water strainer (Bunn-O-Matic part number 23720.1000) should be installed in line, prior to the
flexible water line.
This equipment must be installed to comply with the Basic Plumbing Code of the Building Officials
and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation Manual of the
Food and Drug Administration (FDA).
