Description
This unit involves the skills and knowledge required to safely and effectively install, commission, service and maintain air conditioning systems. It includes the ability to source relevant data and schematics; install components, pipe work, accessories and controls to create a functional air conditioning system. It covers selecting installing and replacing cables within air conditioning equipment operating at voltages up to 500 volt (V) alternating current (a.c.), according to relevant State/Territory legislation and regulations. Commissioning the system to ensure it operates at the specified design conditions, locating and rectifying faults and carrying out routine maintenance procedures.The skills and knowledge of this unit of competency will be applied by refrigeration and air conditioning technicians during the installation, commissioning and servicing of air conditioning systems.To undertake this unit, the learner must have a current Trainee Refrigerant Handling Licence as it includes work on refrigeration and air conditioning equipment that carries the risk of a fluorocarbon refrigerant being emitted.The skills and knowledge described in this unit require a national Refrigerant Handling Licence as it includes work on refrigeration and air conditioningequipment 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.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 V alternating current (a.c.) or 120 V direct current (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, skills and knowledge described in this unit require a relevant contract of training, such as an Australian Apprenticeship. Additional and/or other conditions may apply in some jurisdictions subject to regulations related to refrigeration, air conditioning and electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations. Permits may also be required for some work environments, such as confined spaces, working aloft, near live electrical apparatus and site rehabilitation.
