Nope, I don't agree. The system was working fine for about a month.
After it failed, I pumped in some nitrogen and easily found the leak,
because it was hissing pretty loud.
I was able to let the Sanyo service manager hear the sound via telephone.
Within seconds, he agreed that I had found the leak and said he would ship a replacement for the outdoor unit.
Bad control firmware causes the Sanyo 24KHS72 to run at overly high RPMs,
until one of the safety limits kick in. (Over-load or Over-pressure).
R410A runs a lot more pressure than standard refrigerants.
After a while, it was most likely one of the many
high pressure runs that blew a pin hole
(weak spot?) in the copper tube right above the compressor.
The bad firmware problem is still there, but I now limit the current to 10A.
So my Sanyos* don't even get to try for that 3.6 kW surge anymore..

That's my story, and I'm sticking to it..
