ERA 170C Winterization
I just joined so this is my first post. First of all thanks to everyone who posted anything about winterizing the ERA 170C. Anything on the Model C and stuff on the Alde system was especially helpful. Just purchased my 2015. It wasn’t my first RV but it was my first Class B. I just finished winterizing and thought I’d drop a note as a possible helpful hint.
I wasn’t sure about how to winterize the Alde hydronic system so I followed your posts, operator's/supplement manuals and added some common sense and all seems to be well. Because the Alde was new to me, after I drained all the low water points, I let the Alde system fill up FIRST. It took a full two gallons. When the pink fluid showed in both the input and output lines I knew I was good. My thinking was that with all of the faucets closed, the antifreeze had to be going somewhere so it had to be through Alde lines. After that, opening/closing all the faucets, filling P-traps, cleaning the pump filter, etc. was pretty straightforward. Thanks for the Ideas. I posted a picture of the lines after I winterized.
