Installation & Compatibility Notes

Before servicing the filter, shut off the pump and relieve all system pressure. Remove the old cartridge element and inspect the tank for debris or damage. Insert the new C-7605 cartridge, ensuring proper seating of the cone adapter into the base and aligning the handle end cap properly. Secure the filter lid, restore circulation, and observe the pressure gauge to confirm normal operation and improved flow.

If the cartridge fabric is torn, pleats are deformed or the element is collapsing under pressure, replace it promptly to preserve filtration efficiency.
Keep this cartridge stock-ready in your parts inventory to quickly service common spa or pool filter models and reduce turnaround downtime.
