Installation Notes
- After closing the pool, center the cover so overlap is even on all sides.
- Secure the cover using appropriate hold-downs through the perimeter loops/grommets (commonly water tubes/cover weights).
- Avoid sharp edges and rough coping contact—use protective padding where the cover may rub.
- If water accumulates on top, use a winter cover pump to reduce standing-water weight.
Care & Storage
- Remove heavy leaf piles periodically to reduce stress on the cover and perimeter reinforcements.
- At opening, remove debris first, rinse the cover, and let it dry completely before folding and storing.
- Store in a cool, dry place away from rodents and sharp objects.

Maintenance Tips
- Keep water balanced at closing to help reduce staining and make spring cleanup easier.
