Attach pole to vacuum head. Connect vacuum hose to the vacuum head. Connect skim vacuum to other end of the vacuum hose. Place vacuum head and pole in water. With pool running, hold the skim vacuum over the return to fill hose with water. When vacuum head bubbles to the top of pool and sinks, hose is full. Place skim vacuum over basket in the skimmer. Make sure pump is full of water and move vacuum head slowly across the bottom of the pool to vacuum. When done vacuuming remove vacuum head from the water. Remove skim vacuum and clean basket in skimmer. Do not try to remove the skim vacuum before removing vacuum head from the water. There is too much suction and you can damage the skimmer and other equipment.
