Kinda late, but PM me for a pdf on the 20L winterization- w/ pics- meanwhile see summary attached- pdf file below the pic.
The bypass valve has red and blue pipes on it. Other pics included that are in my big pdf- too large to post here, so PM me for that.
1st Pic with Truma shows valves in winterized position. There is a lift-out access panel there under the driver's side mattress.
Read the Truma manual before you start- it is not to ever be blown out, or have AF in it. There are sensors inside that can be affected..
The valve they talk about is the yellow PRT valve on the floor, towards the outer wall. Lay down to drain.
3rd pic: You will also need to access behind the side panel by the water tank- remove using a #2 square drive bit, and expose the AF fill riser, and shutoff for the water tank. No AF in the tank.
3rd pic shows tank valve closed before adding AF
4th pic- bypass valve (open for winter position)
5th pic- feeding AF via AF riser.
