Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to analyse and evaluate electrical and electronic faults in embedded network air conditioning and heating, ventilation and air conditioning (HVAC) systems of vehicles or machinery in order to initiate action to sustain, vary or enhance performance. It involves identifying, evaluating, selecting, justifying and documenting the most appropriate rectification method or variation to the rectification method. The unit includes the analysis of multi-system and intermittent faults which may be caused by operating in adverse conditions.It applies to those working in the automotive service and repair industry on the air conditioning and HVAC systems of vehicles or machinery.Licensing requirements apply to this unit. Users are advised to check with the relevant regulatory authority.
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 worked on, 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 service and repair workplace or simulated workplace

workplace instructions

manufacturer air conditioning and HVAC system specifications

regulatory and licensing requirements, including:

Australian automotive code of practice: Control of refrigerant gases during manufacture, installation, servicing or de-commissioning of motor vehicle air conditioners

Australian Design Rules (ADRs)

two different vehicles or machinery with air conditioning and HVAC system faults specified in the performance evidence

diagnostic equipment for air conditioning and HVAC systems

tools, equipment and materials appropriate for analysing and evaluating air conditioning and HVAC systems.
