carrying out standard electrical tests in accordance with specifications

completing all relevant standard, code or local required documentation.

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)

procedures and industry best practice for brazing refrigeration pipework

procedures for complying to all legislative and regulatory requirements for safely removing the refrigerant and charging and evacuating the system

procedures for evacuating system, pressure and leak testing, handling and adding refrigerant and checking air flow

safety and legislative requirements for handling refrigerants

standard electrical measurements for earth continuity, insulation resistance, circuit resistance, supply voltage and current

measuring instruments/equipment, specifications and procedures for checking temperature, system performance and testing components

specifications, operational characteristics and process for identifying system components

process for identifying refrigerant type

requirements and procedures for reporting non-compliances completing documentation.

Assessment Conditions

Assessors must:

have vocational competency in installing, servicing and repairing domestic air conditioning and refrigeration appliances 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.
