SRUA Models require 2-wire, grounded service rated 230 volts ac, 30 amp, single phase, 50 Hz. Proceed as follows:

ELECTRICAL INSTALLATION INSTRUCTIONS

CAUTION – Improper electrical installation can damage the equipment and injure the installer. The chassis must be properly grounded. Do not assume a plumbing line will provide an adequate ground.

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.Before electrically connecting the brewer, remove the left side panel from the hood and rotate the control thermostat knob fully clockwise to the "OFF" position. Keep this knob in the "OFF" position until performing the Initial Setup. Replace the side panel.

4.Remove the lower front panel and connect the proper electrical service to the terminal block.

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

6.Disconnect the brewer from the power source. If plumbing has been hooked up, the brewer is ready for the Initial Setup.

NOTE: A Schematic wiring diagram is included in this manual.

PLUMBING REQUIREMENTS

The brewer must be connected to a cold water system with operating pressure between 20 and 90 psi (138 and 621 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 (621 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 from the 1/2" water supply line. 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.
