I’ve been running it like you mention for the last year with the ato turned off. I run a small fan to force more evap if I notice too much is dosing. Not very often.Also if you use kalkwasser you can dose the approximate amount of evaporative loss you have so that you almost never need to have your ATO on, decreasing noise/risk.![]()
My Versa doses more when the container it pulls from has more volume in it. I don't know if that is a versa issue or standard. It pulls/pushes RO into the kalk reactor.
