Electrical Requirements - Bunn ITCB DV Installation & Operating Manual

Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit
requirements.
"Optional Field Wiring ratings are located on the machine near the dataplate."
WARNING - The brewer must be disconnected from the power source until specified.
WARNING - The power cord must be UL Listed, Flexible Cord Type SO, SJO, SJTO, HSJO or SJOW, Rated 90° C,
and the attachment plug cap must be UL Listed, in order to avoid a hazard. The Power Supply Cord must be at
least 3 feet long and maximum 6 feet long (measured from Strain Relief to end of the Attachment Plug Cap).

CAUTION – Improper electrical installation will damage electronic components. Damage caused by incor-
rect electrical connections is not covered by warranty.
1. An electrician must provide electrical service.
2. Determine the available on-site electrical service.
3. (Steps 3 & 9 apply to DV models only) Select the desired unit voltage based on the available on-site elec-
trical service.
4. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
5. Remove the back panel to gain access to the terminal block.
6. Feed the power cord through the strain relief and connect it to the terminal block(s).
7. Connect the power cord to the terminal block (see illustrations above for correct wiring).
8. Before proceeding, verify adequate voltage is present at the field wiring terminal block using a voltmeter.
9. Set the dual voltage switch to the appropriate position and replace the access panel.
10. If plumbing is to be hooked up later be sure the brewer is disconnected from the power source. If plumb-
ing has been hooked up, the brewer is ready for Initial Set-Up.
