Carefully remove all components from the packaging. Inspect the cleaner and its accessories for any signs of damage. If any damage is found, do not operate the unit and contact customer support.
2. Connecting the Power Supply
- Place the power supply unit at least 3.5 meters (11.5 feet) from the edge of the pool. Ensure it is in a shaded area and protected from direct sunlight and splashing water.
