Maintenance and Troubleshooting
Regular upkeep ensures peak performance․ This section details filter cleaning, brush inspection, and solutions for common error codes encountered with your Nautilus CC․
Cleaning the Filter Cartridge
Maintaining a clean filter is crucial for optimal cleaning performance of your Dolphin Nautilus CC․ Regularly inspect the top-load filter cartridge for debris accumulation – frequency depends on pool usage and environment․ To remove, simply lift the filter door and extract the cartridge․
Rinse thoroughly with a garden hose, using a strong spray to dislodge particles․ Avoid using harsh chemicals or detergents, as these can damage the filter material․ For stubborn debris, a gentle soaking in a filter cleaning solution (specifically designed for robotic pool cleaner filters) may be necessary․
Ensure the cartridge is completely dry before re-inserting it into the Nautilus CC․ A damaged or improperly cleaned filter will significantly reduce cleaning efficiency and could potentially harm the unit․ Replace the filter cartridge when it shows signs of wear and tear, or if cleaning no longer restores adequate flow․
Inspecting and Cleaning the Brushes
The active brushes on your Dolphin Nautilus CC are vital for scrubbing and loosening dirt and algae from pool surfaces․ Regularly inspect the brushes for wear, tear, or entanglement with debris like leaves or hair․ This inspection should occur alongside filter cleaning․
To clean the brushes, first ensure the unit is powered off and disconnected from the power supply․ Remove any visible debris by hand, carefully untangling any wrapped materials․ For a more thorough cleaning, you can gently rinse the brushes with water, avoiding high-pressure sprays that could damage them․

If brushes are significantly worn or damaged, they should be replaced to maintain optimal cleaning performance․ Worn brushes reduce scrubbing effectiveness, impacting the overall cleanliness of your pool․ Replacement brushes are readily available and easily installed – refer to the parts diagram for correct orientation․
