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.Open the front door of the dispenser and place the heater switch in the “OFF” (upper position).

4.Remove the right side panel of the dispenser.

120 volt versions proceed to step 6.

120/240 volt and 240 volt versions proceed to next step.

5.Install the electrical wiring to the terminal block as illustrated above.

6.Connect the dispenser to the power source and verify the voltage at the terminal block. Reinstall the side panel.

7.If plumbing is to be hooked-up later be sure the dispenser is disconnected from the power source. If plumbing has been hooked-up, the dispenser is ready for Initial Fill & Heat.

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.

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 Sanita- tion Manual of the Food and Drug Administration (FDA).
