- Rinse 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 and lubricate tank O-rings lightly with silicone lube during service to help maintain a consistent seal.
