Steam Heated Brewers - Fetco CBS-71A User Manual

•
Install a water shut off valve near the brewer to facilitate service. If an in-line water filter is used, it should be
installed after the water shut off valve and in a position to facilitate filter replacement.
•
Before connecting the water line to the brewer, flush the line and water filter thoroughly to remove any debris.
•
Connect the water line to the brewer, and turn on the water to check for leaks.
Electrical connection
(Steam heated brewers - see next section)
•
Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
brewer's serial number plate. Make sure the electrical service includes neutral.
•
A fused disconnect switch or circuit breaker on the incoming power line must be conveniently located near the
brewer, and its location and markings known to the operators.
•
The body of the brewer must be grounded to a suitable building ground. A ground lug is provided in the brewer
next to the power terminal block. Use only 10 gauge copper wire for grounding.
•
Make sure that both power switches are in the "off" position. The buttons should be in the "out" position.
•
Connect the power, neutral, and ground wires to the terminals in the brewer.

Turn on the building circuit breaker. Do not turn on the brewer's power switches yet.
•
At the brewer's terminal block, verify that the correct voltage is between terminals, according to the diagram
above.
•
CBS-71A - press the power switch. CBS-72A - press only the power switch on the brewer's left side. The power
switch will illuminate. After a delay of 5-6 seconds, the tank should begin filling with water.
•
CBS-72A - You can press the right side power switch at any time to begin filling the other tank, but this will cause
the first tank to fill more slowly. To fill the first tank as fast as possible, wait until it has filled completely before
pressing the right side power switch.
•
The heating process will begin after the water has reached a safe level, but before the tank has filled completely.
Approximately 10-15 minutes after the tank has filled, the ready light will illuminate, indicating that this side of the
brewer is at the proper temperature and ready to operate.
