Learning Outcomes and Application | This unit describes the performance outcomes required to retrofit and modify air conditioning systems, including heating, ventilation and air conditioning (HVAC) systems, fitted to a range of vehicles and machinery. It involves preparing for the task, selecting the correct de-gas procedure, carrying out the retrofit and modification procedures, performing post-modification testing, and completing workplace processes and documentation.Air conditioning systems may contain a mixture of both natural and flammable synthetic refrigerants that are difficult to accurately identify and safely recover. To minimise the possibility of ignition, the procedures and equipment used when recovering refrigerants must be those required for flammable refrigerants.It applies to those working in the automotive service and repair industry. Automotive air conditioners, including HVAC systems, include those in agricultural machinery, heavy commercial vehicles, light vehicles or mobile plant machinery.Licensing requirements apply to this unit. Users are advised to check with relevant regulatory authority. An Australian Refrigeration Council accredited (ARCtick) Refrigerant Handling licence is required for those carrying out this work. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Assessors must satisfy NVR/AQTF assessor requirements and hold an Australian Refrigerant Council (ARC) Refrigerant Handling licence. Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting. Assessment must include direct observation of tasks. Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the air conditioning and HVAC systems that they have retrofitted and modified, e.g. repair orders. Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application. The following resources must be made available: automotive repair workplace or simulated workplace workplace instructions vehicle or machinery air conditioning and HVAC system manufacturer specifications Australian automotive code of practice: Control of refrigerant gases during manufacture, installation, servicing or de-commissioning of motor vehicle air conditioners two different vehicles or machinery with air conditioning and HVAC systems requiring retrofitting and modification retrofit, modification and testing equipment for air conditioning and HVAC systems, including: manifold and gauge set recovery unit vacuum pump leak detector refrigerant analyser. |
