Description

This qualification covers competencies in high-level fault diagnosis and rectification, commissioning and maintenance of refrigeration systems and equipment that apply to commercial food storage and preservation, air conditioning, air distribution equipment and/or special applications. It includes regulatory requirements for purchasing and handling refrigerants.
Competency development activities in this qualification are subject to regulations directly related to licencing. A relevant contract of training through an apprenticeship or relevant employment may be required to enable the application of the required knowledge and skills to on the job work activities and environments.
Refrigerant Handling Licence:
The achievement of the qualification meets the training components for the full national Refrigerant Handling Licence which is required to work on refrigeration and air conditioning equipment that carries the risk of a fluorocarbon refrigerant being emitted while decanting the refrigerant or manufacturing, installing, commissioning, servicing, maintaining or decommissioning refrigeration and air conditioning equipment.
Refrigeration and Air Conditioning Occupational Licence:
Additional and/or other conditions may apply in some jurisdictions subject to regulations related to refrigeration/air conditioning work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.
Electrical Occupation Licence:
The achievement of this qualification with the core restricted electrical units meet the electrical regulatory requirements for related restricted electrical work in most state/territories. This is required to work on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.).

Schedule
Packaging Rules
A total of 1350 weighting points comprising:
- 1170 core weighting points listed below; plus
- 180 general elective weighting points from the general elective units listed below.

Choose a total of 180 weighting points elective units from the list below, of which between 0 and 90 weighting points can be taken from Group A; and between 0 and 90 weighting points must be taken from Group B; and between 90 and 180 weighting points must be taken from Group C; or all electives units of 180 weighting points can be taken from Group C.

Up to 90 weighting points of the general elective units Group A, may be selected, with appropriate contextualisation, from any relevant nationally endorsed Training Package or accredited course, provided selected units contribute to the vocational outcome of the qualification. Previously assigned weighting points are listed in the UEE Electrotechnology Training Package Companion Volume Implementation Guide (CVIG), if not listed weighting points will be 10 points, unless directed from the Electrotechnology Industry Reference Committee (IRC).
