w/the no maintenance mantra, like there isn't enough other stuff to do. Oh yeah, forgot about the zinc, I do replace that when I clean my Condenser.

Since I had a couple problems, I was searching for why, and perhaps I missed something on the maintenance side, but sounds like everyone else is maintenance & trouble free w/their Sea Frost systems, nice to get confirmation of that.

Thanks again, cheers, John

PS Dave > in addition to eBay, cans of R12 are readily available & inexpensive in the Bahamas, if you ever make it there.
