Unit Descriptor
Unit descriptor |
This unit describes the performance outcomes required to retrofit and modify automotive air conditioning systems - including heating, ventilation, air conditioning and cooling (HVAC) systems - that are fitted to a range of vehicles and equipment for passenger convenience and comfort. The unit involves diagnosing deviations from correct operation, the retrofit and modification of vehicle air conditioning and HVAC system components and associated systems, and applying post-modification testing procedures. The unit also involves identifying and confirming work requirements, preparing for work, de-gassing and re-gassing systems, and completing work finalisation processes, including clean-up and documentation. Licensing, legislative, regulatory or certification requirements apply to this unit. Users are advised to check with the relevant regulatory authority. |
Application of the Unit

Overview of assessment |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge. A person who demonstrates competency in this unit must be able to:
|
Context of, and specific resources for assessment |
Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting. Assessment is to occur:
Assessment is to comply with relevant:
The following resources must be made available for the assessment of this unit:
|
Method of assessment |
Assessment must satisfy the endorsed Assessment Guidelines of this Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge. Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application. Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients. Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed. |
