not too worried about corrosion at this stage - more worried about the solder joints. but when not in operation I drain the cooliing liquid from the system (PC/RC/AC) and will probably change the water regularly once a week at least for the next few months (there is still some compressor oil coming out of the AC unit).

Just a quick heads up. I have been using my AC recirculation system for about a year now and have done about 30 runs. Works great. However, lately I noticed a significant drop in flow rates (less than 1L/min). I suspected the cheapo Ozito pump at first, but discovered that the AC unit contains two in-line filters (one mesh-type and another mesh/silica beads type). These are relatively close to the actual heat exchanging coils and quite hidden inside the copper piping (so not obvious). They were clogged quite severely with dust etc. I removed them and flow rates were back up to initial rates in excess of 10L/min. Will replace them with an inline garden hose mesh strainer.

Cheers RS

Yeah they would be the dessicant filters to keep water out of the refrigerant gas originally.

Great thread. Have been reading up and trying to discover a way to do this. It seems like you guys have found a suitable system. This is the direction that I'll be heading. Thanks guys. :handgestures-thumbupleft:
