custom-made refrigerator for EBOM project

I am working on EBOM for an old office building which includes an employee cafeteria. The food service contractors brought in custom made commercial refrigerators and installed these custom made commercial refrigerators in the kitchen. The property owner staff surveyed these custom made refrigerators and found that all of these refrigerators are charged with non-CFC refrigerant (HFC or R-22). It is hard to tell the refrigerant leakage rate because the cooling unit are assembled by local workshops. The other challenge is the manufacturing year data in the some refrigerators are missing . Reference guide said that standard refrigerators are not considered part of the base building and are exempt. However, these commercial refrigerators are not "standard refrigerators" because they are custom made. I wonder if we shall input refrigerant related data of these refrigerators in template?
