Installation Notes

  1. Inspect the pool floor and walls; remove sharp debris before installing.
  2. Use a proper liner pad/cove where recommended for comfort and protection.
  3. Fill slowly and smooth wrinkles as water rises for the cleanest finish.
  4. If you're unsure on fit or track type, contact your local store before opening.
PRO TIP
Measure twice. Liners are best confirmed by exact pool size and track type. If your pool is between sizes, ask us before ordering so you don't end up with a liner that won't seat properly.
Color/pattern may vary slightly by production run and lighting. Always verify pool measurements and liner type before opening packaging.
