Thanks for the suggestion Nuneeb. I'm pretty sure it not anywhere on the net..not even the "deep web" smile

Geoff..the heating and cooling times seem to be longer than they should be but without the manuals I can't be sure. For cooling i can being by refilling the compressor gas but don't wanna touch anything until I know a benchmark. Also the cardioplegia flow seems to be less than appropriate..again no way to compare.
