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 electronic control assemblies:

Place the tank heater switch at the top 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. Re- place 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 and 90 psi (138 and 620 kPa) from a 12" 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 (138 kPa). The water inlet fitting is 14" flare.

NOTE – Bunn-O-Matic recommends 14" copper tubing for installations of less than 25 feet and 38" for more than 25 feet from the 12" water supply line. A tight coil of copper tubing in the water line will facilitate moving the brewer to clean the counter top. 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 National Plumbing Code of Canada and the Canadian Food Inspection Agency. For models installed outside Canada, you must comply with the applicable Plumbing/Sanitation Code for your area.
