R-410A is a PED group 2 fluid, and R-32 is a group 1 fluid. A machine that is CE certified for a group 2 fluid will no longer be CE certified for a group 1 fluid. It is therefore not possible to replace R-410A in an existing air conditioning system with R-32 without prior certification.
If this operation is envisaged, it is essential to check all the points relating to safety and regulations.
- preloaded equipment: this option must be confirmed with the manufacturer
- equipment installed by an operator: compatibility must be checked or all the installation components covered by the PED must be requalified for the new fluid
Other points to consider :
- Labelling must be modified accordingly.
- Change in GWP :
- a) possible change in leak testing frequencies.
- b) possible modification of F-Gas constraints for servicing and maintenance.
- c) mandatory relabelling of equipment
- d) modification of equipment manuals.
