This process applies to all TAB 400 models equipped with the Naultius P3.

Introduction

Dewinterizing your nuCamp TAB 400 involves draining RV antifreeze, sanitizing the system, and flushing it with fresh water. This process is typically done in the spring, once the risk of freezing weather has passed.




1. Drain the Black and Gray Tanks

  • Pull the black tank handle to drain RV antifreeze.
  • Pull the gray tank handle to drain antifreeze from that system.
  • Once emptied, close the release levers.

2. Drain Any Remaining RV Antifreeze

  • Open the low-point drain valves for both cold and hot water lines.
  • If antifreeze is present in the freshwater tank, drain that as well.
  • Once the draining stops, close all valves.

3. Prepare the Sanitizing Solution

  • Mix your sanitizing solution based on your preference.
  • A stronger solution can be immediately rushed while a weaker solution will need to sit to sanitize effectively.
  • Recommended: 1/4 cup per 15 gallons. Let rest for 12 hours.
  • Set the Nautilus panel to Sanitize mode using the key on the sticker.
  • Connect a garden hose to the water inlet.
  • Place the other end of the hose into the sanitizing solution.

4. Siphon the Sanitizing Solution

  • Turn on the water pump.
  • The Nautilus system will siphon the solution into the tank.
  • Once the freshwater tank is full, turn off the water pump.
  • Set the Nautilus panel to Dry Camping mode.

5. Run the Sanitizing Solution Through the System

  • Inside the camper, turn on the water pump.
  • Run sanitizing solution through all faucets and fixtures.
  • Don't forget to run water through the external shower.
  • The solution will collect in the gray tank, so empty it once done.

6. Flush the System with Fresh Water

  • Set the Nautilus panel to Power Fill mode.
  • Connect the garden hose to the City Water connection.
  • Monitor the panel to prevent overfilling.
  • Once the tank is full, switch the Nautilus panel back to Dry Camping mode.

7. Final Fresh Water Flush

  • Turn on the water pump.
  • Run fresh water through all faucets and fixtures to remove residual bleach solution.
  • Once the system is flushed, you are ready for the camping season.
