TROUBLESHOOTING

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encoun- tered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.

•Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.

•All electric components have 120 volt ac voltage on their terminals. Shorting of terminals or the application of external voltages may result in equipment failure.

•Intermittent operation of electronic equipment is unlikely. Component failure will normally be permanent. If an inter- mittent condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.

•Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are energized for more than ten minutes without a supply of water.

•The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help to avoid twists and kinks in the tubing.

•Make certain that all plumbing connections are sealed and electrical connections tight and isolated.

•This brewer is heated at all times unless disconnected from the power source. Keep away from combustibles.

WARNING

•Exercise extreme caution when servicing electrical equipment.

•Disconnect the brewer from the power source when servicing, except when electrical tests are specified.

•Follow recommended service procedures

•Replace all protective shields or safety notices
