Initial Set-Up.
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.
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.
Replace 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
These brewers must be connected to a cold water system with operating pressure between 5 and 90 psi (34.5
and 620 kPa) for CDBC models and 20 and 90 psi (138 and 620 kPa) for CEZ models 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 (620 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is
3
8" flare. Bunn-O-Matic
does not recommend the use of a reverse-osmosis or deionized water supply to this equipment.
NOTE - Bunn-O-Matic recommends
3
8" copper tubing from a
1
2" or larger 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).
Plumbing Hook-Up
1. Flush the water line.
2. Securely attach it to the flare fitting at the rear of the brewer.
3. Turn on the water supply.
One circuit models require one 3-wire, grounded service rated 120/208
or 120/240 volts ac, 40 amp, single phase, 60 Hz.
Two circuit models require two 3-wire, grounded service rated 120/208
or 120/240 volts ac, 20 amp, single phase, 60 Hz.
