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 front panel beneath the sprayhead.

Models with digital brewer control assembly:

Place the tank heater toggle switch at the bottom left of the control assembly in the "OFF" position.

Models with electro/mechanical thermostats:

Rotate the control thermostat knob fully counterclockwise to the "OFF" position.

4.Feed the cord through the strain relief and connect it to the terminal block.

5.Connect the brewer to the power source and verify the voltage at the terminal block before proceeding. Replace the front panel.

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

This brewer 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 3⁄8" flare.

NOTE – Bunn-O-Matic recommends 3⁄8" copper tubing for installations of less than 25 feet and 1/2" 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).

Plumbing Hook-Up

1.Remove the 3⁄8" flare cap from the bulkhead fitting on the bottom of the brewer.

2.Flush the water line and securely attach it to the bulkhead fitting on the bottom of the brewer.

3.Turn on the water supply.
