ABSTRACT
Systems designed having the latest materials of construction will operate reliably for many years with a minimum of equipment maintenance. The most important maintenance is cell cleaning. This maintenance should be considered an essential part of a preventive maintenance program. All other equipment will require mechanical, instrument, and electrical maintenance. When systems malfunction, identifying the problem may be difficult where the equipment environment is severe. The trend toward more complex equipment control schemes provides an environment for complex instrument and control failures. If not, the equipment may fail due to electrical junction corrosion faults. The use of antifungal lacquer on electrical terminations and controls after all equipment is in operation will assist in preventing these types of field problems. The chapter provides some of the more common elements of electrochlorinator fault analysis. A brief discussion of fault analysis is provided as an example of an approach used to trace field problems.
