Do not place inflatable pool on mud, sand, or any other hard surfaces. It is recommended to place a tarp under to protect the kiddie pool from puncturing by sharp objects.
You should inflate the 3 individual air chambers from bottom to top.
Please inflate to 90% through the bigger valve and close the bigger valve, then inflate through the smaller one to 100%.
Please fill the inflatable pool with water to the second ring (around 70%) to avoid water overflow.
You can deflate all 3 chambers to drain the pool quickly, or, to prevent water from flooding, open the inside drain valve to slowly discharge the water to your desired place.
Dry the kid pool completely before you fold and stock it in a cool and dry place.
