Repair and service carbon dioxide refrigeration systems
Assessment tool
Version 1.0
Issue Date: May 2024
This unit involves the skills and knowledge required to repair and service carbon dioxide (CO²) refrigeration system.
It includes servicing and repairing refrigeration equipment using CO² as a refrigerant excluding self-contained trans-critical systems. It also includes applying safe working practices and refrigeration principles that apply to CO²; following service manuals; testing, locating and rectifying faults and defective components; and completing the necessary service documentation.
The skills and knowledgein this unit will be applied by refrigeration and air conditioning technicians during the service and repair of refrigeration systems using CO² refrigerant.
The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c).
Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, skills and knowledge described in this unit require a relevant contract of training, such as an Australian Apprenticeship.
Additional and/or other conditions may apply in some jurisdictions subject to regulations related to refrigeration, air conditioning or electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.
Permits may also be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation.
