Troubleshooting

The following procedures instruct how to locate, evaluate, and fix a problem when HydroGuard issues an
alarm or indicates suspect chemical levels. Table 8 outlines some controller problems that may generate a
false alarm, potential causes and solutions. Table 9 outlines some possible problems associated that may
occur but will not generate an alarm and their potential causes and solutions.
