Re: R 404a for r 402 a dorin comp
if the compressor and the installation is filled with old type oil (3GS), than you have to retrofit, changing the oil with syntethic oil. if there is not more than 3% old oil inside the compressor, you can change to the new gas R404A.
if the compressor is older than about 15 years, best ask the factory.

I think so. For R404A just check if the current draw by the compressor motor will still be acceptable.
To make progress is never good enough, I want to do better and better and better
