Requirements for brewers without an attached cord set are as follows:
ELECTRICAL REQUIREMENTS
WARNING - The brewer must be disconnected from the power source until specified in Initial Set-Up.
Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit requirements.
120/208 & 120/240 volt ac models
Note: This electrical service consists
of 3 current carrying conductors
(Neutral, L1 and L2) and a separate
conductor for earth ground.
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 sprayheads.
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
This brewer must be connected to a cold water system with operating pressure between 20 and 90 psi (138
and 620 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 (620 kPa) to reduce it to 50 psi (345 kPa).
The water inlet fitting is
3
⁄
8
" 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 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.
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 backflow
prevention 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.
PLUMBING HOOK-UP
1. Flush the water supply line and securely attach it to the flare fitting or adapter located on rear of brewer.
2. Turn on the water supply.
