Application

This unit of competency defines the skills and knowledge required to service domestic and light commercial refrigeration and air conditioning equipment and components.

It applies to retrofitting existing domestic and light commercial refrigeration and air conditioning equipment with alternative refrigerants; reconditioning components; returning to service; testing equipment; and completing service reports for administrative action.

A Refrigerant Handling Licence must be held by any person who carries out work in relation to refrigeration and air conditioning equipment.

What You'll Learn

Assessment Requirements

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 and include:

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

identifying and interpreting charts, lists, catalogues, specifications, drawings and relevant legislation and regulations with respect to servicing and repairing domestic and light commercial refrigeration and air conditioning equipment

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

carrying out preventative maintenance of domestic and light commercial refrigeration and air conditioning according to manufacturers’ specifications using refrigeration/air conditioning techniques/practices

identifying and localising faulty components and confirming malfunction by inspection/testing, and 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 replacement parts from manufacturers’ catalogues to meet the required specifications

undertaking calculations and numerical operations associated with servicing and repairing domestic and light commercial refrigeration and air conditioning

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

completing all maintenance records/reports in accordance with SOPs.

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)

preventative maintenance requirements

procedures for protecting worksite and equipment from ignition sources if refrigerant used is flammable

variations in component identities

operation and characteristics of range of components

procedures for checking refrigeration/air conditioning components for correct operation

tools, equipment and procedures for assembling components

tools, equipment, techniques and procedures for adjusting refrigeration/air conditioning systems for correct operation and to specification

procedures for obtaining authorisation of adjustments outside of operational specifications

procedures for recovery, containment and storage

effect of poor repair practices

processes and resources to select replacement parts

basic electrical principles, testing and fault identification

codes and regulations relevant to the refrigeration/air conditioning industry, including environmental and ozone and greenhouse substance legislation.

Assessment Conditions

Assessors must:

have vocational competency in servicing and repairing domestic and light commercial refrigeration and air conditioning equipment 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.
