Winterization question 2019 30" Classic

I have have a question regarding using compressed air to blow out the plumbing lines and the Alde hot water system. I am not going to use RV anti-freeze at this time.

Do I: 1) drain the hot water tank, close the pressure relief valve and then blow out the lines or 2) do I need to drain the hot water tank, bypass the Alde and then use compressed air; or 3) some other method?

We have a 2018 Classic 30, and in the owners manual it has procedures for winterizing by blowing the lines out. You should have that info for your 2019. It is recommended NOT to exceed 50PSI while doing the procedure. It has worked for us.
