Marking of the propane/propene compressors
The compressors and the system must be marked with the logo "Attention! Risk of Fire" (ISO7010 / ISO3864) in a clearly visible location, Hazard symbol "Attention Risk of Fire" (ISO7010 W021) . This logo must also remain on the compressor if it is returned to the manufacturer. BITZER compressors in R290 and R1270 designs (added P) are already provided with this marking.
