Electrical Hook-Up
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at
the electrical source.
3. Remove the upper and lower rear panels. Turn the knob of the thermostat to
the “OFF” position (fully counterclockwise).
4. Install a strain relief and the proper electrical wiring to the terminal block.
5. Connect the dispenser to the power source and verify the voltage at the termi-
nal block before proceeding. Reinstall both rear panels.

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. 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.
It can be purchased direct from Bunn-O-Matic (part number 00326-0000). 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.
