Electrical Requirements (Models Without Power Cord) - Bunn Dual TF DBC Installation And Operating Manual

ELECTRICAL REQUIREMENTS (Models without power cord)

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.

200 and 230 volt ac
single phase, 60 Hz models
Note: This electrical service
consists of 2 current carrying
conductors (L1 and L2) and a
separate conductor for earth
ground.
ELECTRICAL HOOK-UP
CAUTION – Improper electrical installation will damage electronic components. Damage caused by incorrect
electrical connections is not covered by warranty.
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 to gain access to the terminal block.
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. Re-
place 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.
WARNING – Electrical connections must be made as specified above. Failure to follow these instructions can
result in personal injury, property or equipment damage.
