Note: 1. Pls leave the blower running the entire time while the inflatable is being used. 2. When you hear air "breathing" out of seams and fabric. Don't worry! This is intentional to allow air to escape to stop the bounce house becoming over-inflated. 3. Once fully inflated, anchor the inflatable product to the ground using the stakes provided. 4 Do not set up in windy or rainy conditions.
