In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard provides for the production and understanding of air conditioning and ventilation duct and plant layout drawings. The focus is knowledge, skills, values and attitudes in relation to the learner's own context and experience of the world of work.

The qualifying learner is capable of:
  • Demonstrating an understanding of air conditioning, ventilation duct and plant draughting.
  • Interpreting and drawing schematic drawings.
  • Identifying and locating air diffusion grilles, diffusers and louvers.
  • It is recommended that learners also have a basic understanding of duct sizing using the static regain and equal friction methods. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Communication, Mathematical Literacy and Computer Literacy at NQF Level 3. 

  • UNIT STANDARD RANGE 
  • Air duct draughting standards with reference to SANS 1238-2003, Air Conditioning ductwork. SANS 10173-2003, the installation testing and balancing of air conditioning ductwork.
  • Flow diagrams of systems shall include plant and mechanical layout drawings, dimensioning, mark numbers, flow arrow and duct size dimensioning.
  • Air conditioning and ventilation equipment and plant. Including roof top and split package air conditioning units, air handling units, air diffusion outlets, chillers, pumps, cooling towers and condensers.

    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.
