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 230V 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” tubing for installations of less than 25 feet and 3/8” for more than 25
feet from the 1/2” water supply line. A coil of 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 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.
