Description | ||||
Employability Skills | ||||
Learning Outcomes and Application | This unit involves the skills and knowledge required to diagnose and rectify faults in complex air conditioning/refrigeration systems.It includes working safely, interpreting technical data and applying knowledge of complex refrigeration/air conditioning system operating parameters to logical fault-finding processes. It also includes implementing fault rectification, safety and functional testing, and completing and reporting fault diagnosis and rectification activities and outcomes.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 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. | |||
