Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package. |
Application
This unit involves the skills and knowledge required to verify the functionality and compliance of refrigeration and air conditioning installations. It includes testing and visual inspection for verifying that a refrigeration and air conditioning system and components are safe and complies with requirements and functions as intended. It also includes working safely, conducting compliance tests, conducting visual inspections, identifying non-compliance defects and completing mandatory reporting requirements. Individuals will typically work remotely without direct supervision or as part of a commissioning, service or maintenance team. To undertake this unit, the learner must have a Trainee Refrigerant Handling Licence as 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 as 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 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. Those holding the Full Refrigeration and Air Conditioning Refrigerant Handling Licence issued by the Australian Refrigeration Council, or a Certificate III in Refrigeration and Air-conditioning trade qualification or equivalent meet the requirements of this unit and its prerequisite requirements. Permits may also be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation. |
