Possibility of antifreeze in Alde

CamperQue

Looking to pick up a 2022 Tab 400 in the next couple weeks and am afraid that the dealer may not have used the Nautilus system bypass when winterizing which may have allowed antifreeze to enter the Alde.
If this is the case it has been mentioned that the Alde system should not be started until the Antifreeze is drained.
I will try to make sure that the Alde is not started until I can confirm and wanted to ask what would be the recommended steps to drain and flush the Alde system if indeed Antifreeze is present to prevent any damages.
Thanks

Drain the Alde first by opening the valve under the bed near the Alde.  See what comes out when you do that.  If antifreeze comes out then you have it in your water heater.  If so then I would fill it with water using the city water settings and drain it out several times.  If nothing comes out when you first open your Alde drain then you should be just fine.

Look through your Nautilus manual for the section on "Dewinterizing" or "Sanitizing".  It isn't hard to do.
