PURPOSE OF THE UNIT STANDARD

People in the field of manufacturing and engineering require the skills, values and knowledge reflected in this unit standard. The learning outcomes in this unit standard also contribute to the exit level outcomes required for various manufacturing and engineering qualifications. The learners is able to fit air-con kits to a vehicle air-conditioning systems and to charge, commission and test the system using product specific service manuals, work instructions and in accordance with workshop and manufacturers manual procedures. This will contribute to the exit level outcomes required for the National Certificate in maintaining vehicles and related qualifications.

PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD:

This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
