Winterizing your TAB 320 LITE is critical to protect the plumbing from freezing temperatures. The basic process of winterizing is simple, and can be distilled into three key steps: 


  1. Drain the water out of the system. 
  2. Used compressed air to blow out the lines. 
  3. Fill the system with antifreeze. 


Jordan, a technical support specialist, walks you through these steps to make winterizing a breeze. Here’s a more in-depth look at winterizing your TAB 320 LITE: 


1. Drain all water from the plumbing system. This includes the hot and cold water lines, the gray tank, and the fresh water tank. Once everything has fully drained, close all drains and valves.


Tip: For extra protection, we recommend blowing out the water lines. While this step isn’t as critical as draining the system and adding antifreeze, it helps remove any trapped water that could freeze and damage your pipes. 


2. Connect an air compressor to the city water inlet and set the pressure to no more than 40 PSI. Open one faucet at a time and let air flow through the lines. If there’s any remaining water, you’ll see it spray out as the air moves through the system.


3. Locate the winterization hose. It is inside the cabin, under the driver's side dinette bench. You may need to remove these panel screws to access the hose. This hose is connected directly to the water pump, allowing it to siphon antifreeze into the system. Remove the cap and place the hose into a jug of RV antifreeze. Turn the diverter valve near the base of the hose so that the pump pulls from the winterization hose. 


4. Turn on the water pump and run antifreeze through all faucets and fixtures. Start with the kitchen faucet, running both the hot and cold sides until you see pink antifreeze. Repeat this process in the bathroom, and don’t forget the exterior shower. 


5. Back outside the unit, run antifreeze through the water heater drain valve. 


6. Flush the toilet to get antifreeze into the cassette, and pour some down the drain. 


7. Once these steps are complete, your TAB 320 LITE is fully winterized and ready for storage until your next adventure.
