Place a tarp on the ground where the outdoor inflatable pool will be located. The tarp should be larger than the pool. The extra tarp area around the outdoor inflatable pool will become a border area; this will allow people to wipe off their feet or place their swim shoes before getting in the pool.

Lay the inflatable pool down on top of the tarp. Stretch out the inner liner so it is flat and smooth. Walk around the inflatable pool to ensure there is equal distance from all sides.

Begin filling the outdoor inflatable pool with water. Once the inside pool bottom is covered with a small layer of water, turn off the hose and walk around the inside of the inflatable pool. Make sure the bottom of the pool is smooth and stretched out. Continue filling the inflatable pool with water.

Have four people stand outside the inflatable pool in a north, south, east and west direction. Each person should hold up the inflatable pool wall as the pool fills with water. Make sure the pool does not bunch up or overlap. Pull the inflatable pool walls tight so they are smooth. Fill the water up to the tube at the top of the pool.

Put together the ladder that will go inside the outdoor inflatable pool. The legs connect to the two railings with screws. The pump connects to two hoses. Install one hose in the open slot at the top of the inflatable pool. This is where water will drain out of the pool into the pump. Connect the other hose to the open slot halfway down the pool. This is where the water will enter the inflatable pool from the pump. Use the release value at the top of the pump to let air escape from the pump. All air needs to be removed from the pump before operating.
