Servicing Hydrocarbon

Overview

This cooler utilises hydrocarbon (HC) R290 as its refrigerant. R290 is a
natural refrigerant that has a very low environmental impact.

Special service requirements are needed as R290 is a flammable
refrigerant.

Safety hazards

The main R290 safety hazards are:



Flammable refrigerant.



Venting of R290 and compressor oil.



Asphyxiation.

SKOPE does NOT recommend performing hazardous activities on the
refrigeration system. See “Refrigeration System” on page 39 for more
information including examples of hazardous activities.
