ELECTRICAL REQUIREMENTS
CAUTION - The brewer must be disconnected from the power source until specified in Initial Set-Up.
120V model brewers require 2-wire, grounded service rated 120 volts ac, 15 amp, single phase, 60 Hz.
"A" model brewers require 2-wire, grounded service rated 230 volts ac, 10 amp, single phase, 50 Hz.
"B" model brewers require 2-wire, grounded service rated 100 volts ac, 15 amp, single phase, 60 Hz.
Proceed as follows:
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 top cover from the brewer.
4. Rotate the control thermostat knob fully counterclockwise to the "OFF" position and replace the top cover.
5. Connect the brewer to the power source.
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
These brewers 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 (621kPa) 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).
