I just went through calculating walk-in Cooler and Freezer condensers for our school kitchen. I found that the 1 and 2 ton units with R404A refridgerant that we typically specify are charged with 9lbs and 20lbs. This is quite a bit off from 2lb-4lb max. Anyone find an attractive alternative for walk-ins to meet this credit?

I don't understand the question—what maximum level are you referring to?
