ELECTRICAL HOOK-UP
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service.
2. Determine the available on-site electrical service.
3. Select the desired unit voltage based on the available on-site electrical service.
4. Using a voltmeter, check the voltage and color coding of each conductor at the electrical source.
5. Remove the front access panel beneath the sprayhead to gain access to the terminal block.
6. Feed the supply leads through the rear of the brewer.
7. Using the above diagrams, connect the desired electrical service to the fi eld wiring terminal block.
8. If wiring the machine for operation on 120/208 or 120/240 volts with a Power Supply Cord, the Power Supply
Cord must be UL Listed Flexible Cord Type SO, SJO, SJTO, HSJO or SJOW, No. 12 AWG, 4 Conductor, Rated
90° C. Attachment Plug Cap must be UL Listed, NEMA 14-20P or L14-20P Confi guration, Rated 125/250V,
20 AMPS. 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).
9. Before proceeding, verify the voltage at the fi eld wiring terminal block.
10. Set toggle switch on component bracket to the appropriate position and replace the access panel.
11. 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.
