•Inspection, testing, and repair of electrical equipment should be performed only by qualified service person- nel.
•All electronic components have 120 volt ac and/or low voltage dc potential on their terminals. Shorting of terminals or the application of external voltages may result in board failure.
•Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an intermittent condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.
•Keep away from combustibles.
WARNING – • Exercise extreme caution when servicing electrical equipment.
•Unplug the dispenser when servicing, except when electrical tests are specified.
•Follow recommended service procedures
•Replace all protective shields or safety notices
