Setup and Assembly
Follow these steps to prepare your Dolphin Nauty TC for its first use:
- Unpack the Cleaner: Carefully remove the Dolphin Nauty TC robotic cleaner and all accessories from its packaging.
- Assemble the Caddy: The cleaner comes with a caddy for easy transport and storage. Assemble the caddy according to the diagrams provided in the separate caddy assembly guide.
- Connect the Power Supply: Place the power supply unit at least 3.5 meters (11.5 feet) from the edge of the pool. Connect the floating cable from the cleaner to the power supply unit, ensuring a secure connection.
- Place the Cleaner in the Pool: Gently lower the cleaner into the pool. Allow it to sink to the bottom, releasing any trapped air bubbles. Ensure the floating cable is untangled and has enough slack to allow the cleaner to move freely.

Troubleshooting
If your Dolphin Nauty TC is not operating as expected, consult the following common issues and solutions:
| Problem | Possible Cause | Solution |
