ELECTRICAL REQUIREMENTS

WARNING - If the power cord is ever damaged, it must be replaced by the manufacturer or its service agent with
a special cord available from the manufacturer or its service agent in order to avoid a hazard.
Refer to Data Plate on the Brewer, and local/national electrical codes to determine circuit requirements.

L1, L2, L3, are the 3 phases
V1 = Phase to phase voltage, between any 2 phases.
V2 = Phase to neutral voltage, L1 to neutral must be 120V.
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 in conformance with all local, state and federal
electrical codes.
2. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
NOTE - The brewer is shipped without a plug on the power cord. Qualified service personnel must select
and install the proper UL listed grounding type attachment plug specified on the rear of the brewer.
3. Install the specified plug on the attached power cord.
4. Remove the front access panel to gain access to the terminal block.
5. Connect the brewer to the power source and verify the voltage at the terminal block before proceeding.
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.
FOR SINGLE PHASE OPERATION
MOVE BLU WIRE INTO TERMINAL
BLOCK WITH BLACK WIRE.
