Uh oh! I need to re-winterize!

[Deleted User]

I was supposed to go on my maiden voyage with my new 400 this weekend so I dewinterized but of course one last surprise hard freeze is coming Sunday night. I'm new to the Nautilius. Which configuration do I use to hook up my air compressor to blow it out before putting in the antifreeze? I have the hose fitting and I've done it several times in my prior 400 and 320. 

I thought about just turning the heat on and putting some AF down the gray and black tanks and working the valves a bit but winterizing isn't that hard so......plus my luck the heat would shut off during the night for some unknown reason.

If you plan to use anti-freeze, there is no need to use a compressor to remove water. Simply run the ani-freeze through to replace the water and call it a day. Arguably you might use a bit more antifreeze, but not very much. With one method you fill the empty lines until the anti-freeze runs and with the other you do the same but use the AF to run out the water. Tomato, tomaaato. In either scenario, run the AF until it runs freely from each faucet. Don't forget the drains.

Here is the document created by @TABNewbies for the 400 with Nautilus.  You will need to set all your valves to a 45 degree angle to first blow out the Nautilus harness via the City Water connection.
