Description
This unit covers installing split air conditioning systems to relevant standards, codes and local regulations.
Notes
Elements and Performance Criteria
1. Locate split air conditioning components
  • 1.1. Required split air conditioning unit, piping and other components are identified from job and manufacturer specifications and diagrams.
  • 1.2. The location of unit components, piping and drains is determined in consultation with customer and other site considerations.
  • 1.3. Industry and local authority requirements, standards and codes and manufacturer requirements are identified including the appropriate capacity rating of the equipment and any impacts on the installation are identified.
2. Inspect and prepare installation sites
  • 2.1. All work is carried out safely to Australian Standards, state and local codes and regulations.
  • 2.2. The installation site is prepared as appropriate to industry codes of practice and manufacturer installation instructions.
  • 2.3. The work is carried out without damage to the system, components and the surrounding environment or services.
3. Prepare split system equipment and materials for installation
  • 3.1. Safety hazards are identified and noted and established risk control measures are implemented.
  • 3.2. Appropriate personnel are consulted to ensure the work is coordinated effectively with others involved on the work site.
  • 3.3. All components, piping and fittings are properly checked for conformance to manufacturer specification, job requirements and applicable standards.The layout of the pipe work is determined from job specifications and diagrams.
  • 3.4. Materials needed to carry out the work are obtained in accordance with established procedures and checked against job requirements.
  • 3.5. Tools, equipment and testing devices needed to conduct the work are obtained in accordance with established procedures and checked for correct operation and safety.
  • 3.6. Preparatory work is checked to ensure no damage has occurred and that it complies with work requirements.
4. Prepare and install refrigerant pipework
  • 4.1. Safe work practices/risk control measures are applied as required.
  • 4.2. Tools and equipment are used safely and in accordance with manufacturer instructions.
  • 4.3. Pipework is prepared and joined to required specification with minimal wastage and damage/contamination to environment.
  • 4.4. Pipework and fittings are joined using appropriate pipe joining methods.
  • 4.5. Pipes are run separately and insulated according to manufacturer instructions and to relevant standards codes and regulations.
  • 4.6. Pipework and joins are checked for compliance and integrity using appropriate testing methods.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to fabricate pipework for split air conditioning systems and install units and components to manufacturer specifications and relevant Australian Standards, codes and regulations.
Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge; and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with installing split air conditioning systems or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways, including direct observation, supervisor reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
