Assessment tool
Version 1.0
Issue Date: May 2024
This unit involves the skills and knowledge required to install and commission Class A2, A2L and A3 flammable refrigerant air conditioning and refrigeration systems, components and associated equipment in accordance with legislative, standard and code requirements. It includes working safely and installing equipment, components and piping to job specifications. It also includes completing pre-commissioning tests, starting the system, ensuring correct refrigerant charge, adjusting components and controls to efficient operation, completing installation and commissioning documentation.
Some flammable refrigerants, for example, fluorocarbons like R32, are controlled under the national Ozone Protection and Synthetic Greenhouse Gas Management Regulations 1995. Therefore, to undertake this unit, the learner must have a relevant Trainee Refrigerant Handling Licence if it includes work on refrigeration and air conditioning equipment that carries the risk of a fluorocarbon refrigerant being emitted.
The skills and knowledge described in this unit require a national Refrigerant Handling Licence if it includes work on refrigeration and air conditioning equipment that carries the risk of a fluorocarbon refrigerant being emitted while decanting the refrigerant or manufacturing, installing, commissioning, servicing, maintaining or decommissioning refrigeration and air conditioning equipment.
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.
