Did I miss it or has no one followed up on the antifreeze in the AV compressors yet I'm carrying just plain water in mine in my shop which I keep above freezing I'm just wondering if antifreeze has been decided whether it's an option or not.
We are all just guessing like you. I wouldnt use just plain tap water or even bottled water. Use distilled water. The manual says only use that. Maybe you could call them and ask.
