3.2 Installation Steps
- Positioning: Place the filter tank on a firm, level surface, preferably concrete, near your pool pump. Ensure adequate space for maintenance.
- Connect Plumbing: Connect the pool plumbing to the filter's inlet and outlet ports. The lower fitting is the output. Use appropriate PVC adapters and ensure all connections are watertight. Apply plumber's tape to threaded connections for a secure seal.
- Install Pressure Gauge: Carefully screw the pressure gauge into the designated port on the filter tank. Do not overtighten.
- Install Air Relief Valve: Screw the air relief valve into its port. Tighten only by hand to prevent damage.
- Insert Filter Element: Ensure the filter element is properly seated inside the tank.
- Secure Locking Ring: Place the top of the filter tank and secure it with the locking ring system. Ensure the O-ring is clean and properly lubricated with a silicone-based lubricant to prevent leaks. Tighten the locking ring firmly.
- Leak Check: After installation, turn on the pump and check all connections for leaks. Address any leaks immediately.

4. Operating Instructions
Once installed, operating your Sure-Flo cartridge filter is straightforward.
- Priming the Pump: Ensure your pool pump is properly primed according to its manufacturer's instructions before starting.
- Starting the System: Open all necessary valves to allow water flow to and from the filter. Turn on your pool pump.
- Air Bleed: As the filter fills with water, open the air relief valve to allow trapped air to escape. Close the valve once a steady stream of water emerges.
- Monitor Pressure: Note the initial pressure reading on the pressure gauge. This is your clean filter operating pressure. As the filter collects debris, the pressure will gradually rise.
- Run Time: Operate your filter for a sufficient period each day to ensure proper water circulation and filtration. Consult your pool professional for recommended daily run times based on your pool size and usage.

5. Maintenance
Regular maintenance of your cartridge filter is essential for clear water and extended product life.
5.1 Cartridge Cleaning
The filter element should be cleaned when the pressure gauge reading is 8-10 PSI above the clean filter operating pressure, or when water flow to the pool noticeably decreases.
- Turn Off Pump: Always turn off the pool pump and close all valves to isolate the filter before performing any maintenance.
- Relieve Pressure: Open the air relief valve to release any trapped air and pressure from the system.
- Drain Water: If necessary, open the drain plug at the bottom of the tank to drain water.
- Remove Locking Ring: Loosen and remove the locking ring. Carefully lift the top of the filter tank.
- Remove Cartridge: Carefully lift the filter cartridge out of the tank.
- Clean Cartridge: Use a garden hose with a strong spray nozzle to thoroughly rinse debris from between the pleats of the cartridge. For stubborn dirt or oils, use a specialized cartridge filter cleaning solution.
- Inspect Cartridge: Check the cartridge for any tears, damage, or excessive wear. Replace if necessary.
- Reassemble: Place the clean cartridge back into the tank, ensuring it is properly seated. Replace the tank top and secure the locking ring. Ensure the O-ring is clean and lubricated.
- Restart System: Follow the operating instructions to restart your filter system.
