Description

This unit involves the skills and knowledge required to solve problems in low voltage (LV) refrigeration and air conditioning circuits, determine the correct operation of LV alternating current (a.c.) circuits, and provide solutions to refrigeration and air conditioning work functions.Competency in this unit requires the ability to work safely; use voltage, current and resistance measuring devices; and provide solutions derived from measurements and calculations to predictable problems in single and multiple path circuits.Individuals will typically work independently or as part of a refrigeration installation and repair team.The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) a.c. or 120 V d.c.Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, a relevant contract of training, such as an Australian Apprenticeship, is required. Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.

Notes

Elements and Performance Criteria

1 Prepare to work on LV refrigeration and air conditioning circuits

1.1 WHS/OHS hazards, risk control methods, relevant standards, codes and legislation are obtained and applied
1.2 Work details are determined from documentation and/or supervisor to establish scope of work to be completed
1.3 Supervisor is consulted to ensure work is coordinated with others
1.4 Tools, equipment and testing devices required to locate faults are obtained in accordance with workplace procedures and checked for operational safety

2 Solve problems in LV refrigeration and air conditioning circuits

2.1 Need to test or measure live electrical work is determined in accordance with workplace procedures and WHS/OHS requirements
2.2 Equipment is checked and isolated as required in accordance with workplace procedures and WHS/OHS requirements
2.3 Measured and calculated values are used to resolve circuit problems, as they apply to single and multiple path electrical circuits in accordance with workplace procedures
2.4 Repair work is carried out in accordance with equipment or manufacturer requirements and workplace procedures
2.5 Unexpected situations are resolved in accordance with workplace procedures, safety guidelines and with the approval of an authorised person/supervisor
2.6 Fault-finding and repair activities are resolved without damage to apparatus, circuits, the surrounding environment and/or services using relevant sustainable energy practices in accordance with workplace procedures

3 Complete work and document activities

3.1 Worksite and equipment are cleaned and made safe in accordance with workplace procedures
3.2 Supervisor is notified of completion of work and relevant documentation is completed in accordance with workplace procedures
