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.

120/208 and 120/240 volt ac three phase, 50 Hz models

Note: This electrical service consists of 4 current carrying conductors (Neutral, L1, L2 and L3) and a separate con- ductor for earth ground.

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.

CAUTION: Do not connect L1 to a circuit operating at more than 150 volts to 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.
