I'm not sure, but I think with R-407C the oil must be changed; but R-417C is a "drop-in" replacement. Check also if thermal expansion valves need to be modified, along with changes in pressure settings.

Please, I am trying to understand the mechanical terminology, can you tell me what do R-22 and R-407C mean and what is their function?

The correct location for the answer to this question is the technical helpline of the manufacturer that supplied the equipment. What was the answer to the question when the telephone call was made?
