Installation & Compatibility Notes
To install, shut off the filter pump and relieve system pressure. Unscrew the old air-relief cap from the filter tank lid, clean the seal surface, and install the new SX200G cap, ensuring it seats correctly. After installation, restore circulation and verify that the filter pressure returns to normal and that no air pockets remain.
Maintenance Tips
- Inspect the cap periodically for cracks, worn threads or ineffective sealing — replace if any issue is found.
- If the filter pressure climbs unusually or airflow seems reduced, use the cap to vent air and evaluate whether the filter media or laterals may also be at fault.
- Keep the part in your standard service parts inventory — it’s a common replacement on filter maintenance visits.
