Electrical Hook-Up

CAUTION – Improper electrical installation will damage electronic components.

1. An electrician must provide electrical service as speciﬁ ed.

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

top lid.

3. Remove the lower rear panel, feed the cord through the strain relief 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 electrical source.

5. Connect the brewer to the power source and verify 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.

WARNING - The brewer must be electrically grounded using the green screw near the terminal block. Do not

assume a plumbing line will provide an adequate ground.

The brewer must be connected to a cold water system with operating pressure between 30 and 90 psi(207

and 621 kPa) from a

⁄

" 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 ﬁ tting is

NOTE - Bunn-O-Matic recommends

feet from the

" 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 ﬂ ow.

As directed in the International Plumbing Code of the International Code Council and the Food Code Manual

of the Food and Drug Administration (FDA), this equipment must be installed with adequate backﬂ ow pre-

vention to comply with federal, state and local codes. For models installed outside the U.S.A., you must

comply with the applicable Plumbing /Sanitation Code for your area.

1. Attach the female ﬁ tting from the short piece of tubing on the strainer/ﬂ ow control (supplied) to the water

inlet ﬁ tting at the rear of the brewer.

2. Flush the water line and securely attach it to the ﬂ are ﬁ tting on the strainer/ﬂ ow control.

3. Turn on the water supply.
