Maintenance Tips
- Rinse the cartridge when pressure rises about 8–10 PSI above your clean starting pressure (or when flow drops).
- Spray between pleats from top to bottom and rotate the cartridge as you clean for a more thorough rinse.
- Deep clean periodically to remove oils; if scale is present, degrease first, then treat for scale and rinse thoroughly.
- Inspect the tank O-ring and sealing surfaces during service and lubricate lightly with silicone pool lube for an easier, more consistent seal.
