1 Servicing Hydrocarbon

Overview

This cooler uses 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 18 for more information, including examples of hazardous

activities.
