CAUTION – Improper electrical installation will damage electronic components.

1.An electrician must provide electrical service as specified.

2.Remove the top lid and rotate the control thermostat knob fully counterclockwise to the "OFF" position.

3.a) 120V brewers have an attached cordset. Plug in the brewer and proceed to #6.

b) 120/208V brewers, feed the cord through the strain refief at the rear of the brewer and connect it to the terminal block.

4.Using a voltmeter, check the voltage and color coding of each conductor at the power source.

5.Connect the brewer to the power source and verify the voltage at the terminal block.

6.If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumbing has been hooked up, the brewer is ready for Initial Set-Up.

PLUMBING REQUIREMENTS

These brewers must be connected to a cold water system with operating pressure between 20 (138) and 90 psi (620 kPa) from a 1⁄2" or larger supply line. A shut-off valve should be installed in the line before the brewer. 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 brewer to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle valve to install the brewer. 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 Sanitation Manual of the Food and Drug Administration (FDA).
