Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions, on at least (2) systems, and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting charts, lists, catalogues, specifications, drawings and relevant legislation with respect to maintaining and repairing commercial air conditioning systems and components

selecting and using equipment to test and check temperature, flow and quality of conditioned air for conformance against specifications, legislation and regulations

carrying out preventative maintenance according to manufacturers’ specifications using refrigeration/air conditioning techniques/practices

checking system components for correct operation using appropriate tools, techniques and test equipment and assessing component performance/operation against specifications

identifying and localising faulty components and confirming malfunction by inspection/testing, making required adjustments to achieve specifications

removing the refrigerant from the system and containing in accordance with procedures and regulatory requirements

removing/dismantling and reassembling faulty components and selecting replace parts from manufacturers’ catalogues to meet the required specifications

undertaking calculations and numerical operations associated with maintaining and repairing commercial air conditioning systems and components

charging the system and verifying correct operation of the equipment to meet specifications

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

measuring instruments/equipment and specifications for checking air temperatures, air flows, air quality and air properties

procedures for performing preventative maintenance on air conditioning systems and sequence of implementation

techniques and procedures for inspecting, testing and assessing system components and operational compliance to meet specifications

procedures for safely removing the refrigerant from the system and charging the system and all legislative and regulatory requirements

tools, equipment, techniques and procedures for dismantling and repairing faulty components, reassembling and testing components

air properties controlled by the air conditioning system

measuring instruments/equipment and specifications required for checking component noise and vibration levels

specifications and process for identifying system components

operational characteristics of the system components

appropriate process for localising and confirming faulty components

selecting and using equipment for testing electrical compliance of equipment

procedures for completing maintenance records/service reports and reporting non-conformances.

Assessment Conditions

Assessors must:

have vocational competency in maintaining and repairing commercial air conditioning systems and components at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
