Do not use the unit if it does not operate properly or has been damaged. Do not try to service the unit yourself - call Goodway for assistance. Service must be performed only by qualified repair personnel. Service performed by unqualified personnel could result in a risk of injury and voids the warranty. - Page 4 Refer to SDS at all times for safety information. WARNING: Don’t assume chemical compatibility – if a chemical other than Goodway’s ScaleBreak® is used you must ensure that the chemical will not damage the internal components (pump, plumbing, valves, etc) of the unit. A full chemical compatibility check must be done first.
