• 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. • 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 28791.1 011500 4 TROUBLESHOOTING (cont.)
