ELECTRICAL REQUIREMENTS
CAUTION - The brewer must be disconnected from the power source until specified in
Initial Set-Up.
The brewer requires either 2-wire, grounded service rated 120 volts ac, or 3-wire, grounded service rated
120/208 or 120/240 volts ac, 20 amp, single phase, 60 Hz. Refer to the product's dataplate above the dilution
nozzle for actual voltage of your particular brewer model.
Electrical Hook-Up
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specified.
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.
PLUMBING REQUIREMENTS
The brewer must be connected to a cold water system with operating pressure between 30 and 90 psi(207
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
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).
1. Attach the female fitting from the short piece of tubing on the strainer/flow control (supplied) to the water
inlet fitting at the rear of the brewer.
2. Flush the water line and securely attach it to the flare fitting on the strainer/flow control.
3. Turn on the water supply.
