ELECTRICAL REQUIREMENTS
CAUTION - The dispenser must be unplugged until specified in Initial Set-Up.
The Model HW2 has an attached cordset and requires 2-wire, grounded service rated 120V ac, 15 amp,
single phase, 60 Hz. The Model Hw2A requires 2-wire grounded service rated 240V ac, 8 amp, single phase, 50
Hz.
PLUMBING REQUIREMENTS
This dispenser must be connected to a cold water system with operating pressure between 20 and 90 psi
(138 and 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. A tight coil of copper tubing in the water line will facilitate moving
the dispenser 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.
This equipment must be installed to comply with the Basic Plumbing Code of the
Building Oficials and Code Administrators Internatiopnal, Inc. (BOCA)
and the Food Service and Drug Administration (FDA).
Plumbing Hook-Up
