Unit of Competency | UEENEEJ185A - Repair and service carbon dioxide refrigeration systems |
---|---|---|---|
Description | 1) 1.1) This unit covers specialised procedures for servicing and repairs to achieve the effective and efficient operation of refrigeration equipment using carbon dioxide (CO2) as a refrigerant excluding self contained systems. It reinforces safe working practice and encompasses applying specialised knowledge of refrigeration principles that apply to carbon dioxide, following service manuals, testing, locating and rectifying faults and defective components and completing the necessary service documentation. | ||
