R/O in off season

[doocat]

This is the first year we are leaving or considering leaving the R/O in the sugar house. We usually take it to the basement to keep it cool. Is there any problems that long time users can think of that would be detrimental to the unit. Does heat play a problem with the membranes even if they are treated with the appropriate solution for bacteria, etc?

Thanks in advance for any replies, Craig

That's where we leave ours.

I leave my mombrane in the sugar house as well. It is sealed and insulated, and wont bet hot in there. Never had any problem with that. The big thing is keeping the RO from freezing.
Make sure all the lines are drained so no goobers start growing.
It is amazing that after washes and rinses bacteria still wants to grow in lines if they aren't drained.

I run a dehumidifier in the RO room during the summer. I also put a stash of dry paper towels inside the electrical box to absorb any extra moisture that may be around. be sure to remove prior to the next startup.

Thanks, I am just a little concerned about the membranes. It does get warm in the sugar house in the summer but I figured that if it was treated it should be good. Just looking for input.
