Blower should remain on and continuously inflate Water Park during use. Air flow through seams is normal. It is normal to see bubbles rising on the surface of the pool and other wet areas of the bouncy castle (water park). During use, the blower will need to work continuously and the seams will ‘bubble’ (every product is tested for functionality prior to packaging, and it is normal for seams to seep air and water into the seams of sewn products). It is common and essential that a small amount of air escapes from the seams, this release helps to maintain a balanced air pressure within the inflatable structure to ensure a safe and enjoyable jumping experience for your child. Use of space: lawn soft ground. The use of the process is shown in the following chart (the manual has a detailed analysis): the water slide - - long air cylinder tied to the blower (inlet cylinder) - - the short air cylinder (outlet cylinder) tied to the blower - - open the blower - - the castle with the auxiliary package of large earth nails fixed on the lawn - - water slide installation of water pipes - - start using (strictly prohibited windy days and rainy days).
