This article and video applies to any nuCamp model equipped with the Nautilus P3.


The Nautilus P3 system is used in the 2025 TAB 320, TAB 360, TAB 400, Cirrus 620, Cirrus 820, and Cirrus 920 models to streamline water management by centralizing essential functions. Below is an overview of its components, functions, and modes.



Step 1: Understanding the Nautilus Panel Components

The front panel of the Nautilus system includes the following key components:

  • City Water Hookup – Connects to city water for direct supply.
  • Black Tank Flush Hookup – Used to clean out the black tank by flushing it with fresh water.
  • Coax Connection for Interior TV – Provides a TV connection inside the camper.
  • Water Pump Switch – Turns on the water pump (identical to the interior pump switch).
  • External Shower – Allows access to hot and cold water outside the camper.
  • Mode Selection Knobs – Adjusts the system’s settings for different functions.
  • Instruction Key Sticker – Provides visual guidance on knob positions for each mode.

Step 2: Nautilus Panel Modes

1. Dry Camping Mode

  • Allows you to pump water from the freshwater tank to your fixtures.
  • Ensure the pump is turned on, either at the Nautilus panel or inside the camper.

2. Power Fill Mode

  • Used to fill the freshwater tank using a garden hose.
  • Connect the hose to the City Water Hookup and allow it to fill the tank.

3. City Water Mode

  • Directly supplies water from a city water connection to your fixtures, bypassing the freshwater tank.
  • No need to use the pump in this mode.

4. Sanitize Mode

  • Used when de-winterizing or sanitizing the system.
  • Connect a bucket or container to the City Water Hookup and siphon liquid into the fresh tank.

5. Winterize Mode

  • Used only during winterization to run RV antifreeze through the system.

Step 3: Using the Black Tank Flush

  • Connect the city water hose to the Black Tank Flush Hookup.
  • This allows fresh water to be forced through the black tank, helping flush out residual waste.

Important Notes:

  • Always use an inline water pressure regulator when connecting to city water (included in your welcome pack).
  • Follow the instructional sticker on the Nautilus panel for proper knob positioning.
