Introduction
This manual provides essential instructions for the safe and efficient operation and maintenance of your Dolphin Proteus DX4 Plus Automatic Robotic Pool Cleaner. Please read this manual thoroughly before using the device to ensure proper functionality and longevity.
Setup
Unpacking and Initial Placement
Carefully remove the robotic pool cleaner and its components from the packaging. Ensure all parts are present and undamaged. The Dolphin Proteus DX4 Plus is designed for plug-and-play installation.
- Position the Power Supply: Place the power supply unit at least 10 feet (3 meters) from the edge of the pool. Ensure it is in a shaded area and protected from direct sunlight and extreme weather conditions.
- Uncoil the Cable: Fully uncoil the floating cable to prevent tangling during operation. The tangle-resistant cable is designed to minimize twisting.
- Submerge the Cleaner: Gently lower the robotic cleaner into the pool. Allow it to sink to the bottom. Ensure no air bubbles are trapped inside the unit.
- Connect to Power: Plug the floating cable into the power supply unit, then plug the power supply into a grounded electrical outlet.

Operating Instructions
Starting a Cleaning Cycle
Once the cleaner is submerged and connected to the power supply, press the ON/OFF button on the power supply unit to begin a cleaning cycle. The unit will automatically start cleaning the pool floor, walls, and waterline.
- Automatic Operation: The Proteus DX4 Plus features smart navigation to efficiently cover your entire pool, including floors, walls, waterline, steps, and sun ledges.
- Cleaning Cycle Duration: The standard cleaning cycle is approximately 2.5 hours. The unit will automatically shut off upon completion.

Removing the Cleaner from the Pool
After a cleaning cycle, or when you need to remove the cleaner:
- Turn off the power supply unit and unplug it from the electrical outlet.
- Gently pull the floating cable to bring the cleaner to the edge of the pool.
- Use the handle to lift the cleaner out of the water. Allow excess water to drain from the unit before placing it on the pool deck.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your robotic pool cleaner.
Cleaning the Filter Basket
The top-load filter basket captures leaves, dirt, pollen, sand, and fine debris. It should be cleaned after each use or when the filter indicator light illuminates.
- Open the top lid of the cleaner.
- Remove the filter basket by lifting its handle.
- Empty the debris from the basket.
- Rinse the filter panels thoroughly with a garden hose until clean.

Storage
When not in use, especially during off-season, store the device in a dry, shaded place, away from direct sunlight and extreme temperatures. Ensure the cable is neatly coiled to prevent damage.
Troubleshooting
If you encounter issues with your Dolphin Proteus DX4 Plus, refer to the following common solutions:
- Cleaner Not Moving or Stopping:
- Check if the power supply is properly connected and turned on.
- Ensure the filter basket is clean and not clogged.
- Verify that the impeller is free from obstructions.
- Poor Cleaning Performance:
- Clean the filter basket thoroughly.
- Check the brushes for wear and tear; replace if necessary.
- Ensure the pool water chemistry is balanced, as excessive algae can hinder cleaning.
- Cable Tangling:
- Ensure the cable is fully uncoiled before placing the cleaner in the pool.
- Periodically straighten the cable during the cleaning cycle if tangling persists.
- Cleaner Not Climbing Walls:
- Check the filter for clogging, as a full filter can reduce suction and climbing ability.
- Ensure the pool water is not excessively cloudy or has high algae content.
- Verify that the brushes are clean and in good condition.
