- Lay down the included ground cloth to protect the pool liner.
2.2 Liner and Frame Assembly
- Carefully unfold the pool liner onto the ground cloth.
- Assemble the galvanized steel frame components using the Easy Lock System. No tools are required as pieces simply snap together.
- Ensure all frame pieces are securely connected and the liner is properly aligned within the frame.

- Filter: Standard operation for continuous water filtration.
- Backwash: Reverses water flow to clean the sand filter.
- Rinse: Follows backwash to flush out dirty water and settle the sand.
- Recirculate: Circulates water without passing through the filter media.
- Drain: Drains water directly from the pool.
- Close System: Shuts off all flow to the filter.
The pump also incorporates Hydro Aeration Technology to improve water circulation, clarity, and freshness.

4. Maintenance
Regular maintenance is essential to keep your pool clean, safe, and extend its lifespan.
- Water Chemistry: Regularly test and balance pool water chemistry (pH, chlorine, alkalinity) to prevent algae growth and ensure swimmer comfort.
- Cleaning: Vacuum the pool floor at least once a week. Use a leaf skimmer to remove debris from the water surface.
- Filter Maintenance: Perform backwashing and rinsing of the sand filter as needed, typically when pressure rises or flow decreases. Sand in the filter can last up to 5 years with regular backwashing.
- Pool Cover: Use the included pool cover when the pool is not in use to keep out debris and reduce water evaporation.
- Structural Care: Periodically hose down the ladder and the exterior of the pool to prevent corrosion and maintain cleanliness.
5. Troubleshooting
Here are some common issues and their potential solutions:
- Cloudy Water: Check and adjust water chemistry. Ensure the filter pump is running for sufficient hours daily and perform a backwash if needed.
- Algae Growth: Shock the pool with appropriate chemicals and ensure proper chlorine levels. Brush pool walls and vacuum.
- Pump Not Functioning: Check power supply, ensure all connections are secure, and inspect for any blockages in hoses or the pump impeller.
- Water Leaks: Inspect the liner for punctures (a patch kit is included for minor repairs). Check all hose connections and fittings for tightness.
