Zodiac CNX 20 Maintenance guides
Water quality, filter load and usage intensity can affect maintenance frequency more than the calendar alone.
What should be checked?
- Track filter pressure and flow changes; clean the filter according to the manufacturer procedure.
- Remove leaves and debris from pump basket, skimmer and suction paths.
- Monitor water chemistry with suitable test equipment and avoid over-dosing.
- Check seals, unions, hoses and housing areas for leaks.
- Inspect robotic cleaner filter basket, brushes, tracks and cable.
- Clean biofilm and scale from hot-tub/spa surfaces regularly.
