Hmm. I should have asked this question a month ago. I've left my system
open to the air that long.
Air conditioning is fairly low on my list of priorities (have to get an
adapter plate made first!) but I would like to avoid any further damage
to the system. I'm only likely to use the evaporator and maybe the
condenser.

I had mine drained by the local air conditioning shop for NZ$25. Took
about 15 minutes.
We chatted about how to make it go once the car was electric. They had
the special Prius compressor oil but I would have to find a suitable
inverter and control system for it. The masterflux compressors might be
easier to get working, especially since there is an inverter off the
shelf. Has anyone used one? I saw the discussion last week, but I
haven't heard of someone actually using one.
