Description
This unit involves the skills and knowledge required to position, assemble, install, start up and decommission single head split air conditioning systems and water heating heat pump split systems, up to a maximum of 18 kilowatt (kW) refrigeration capacity.It includes following standards, codes of practice, regulatory requirements and routine procedures to install equipment, connect pipe work, pressure test, evacuate, perform functional checks and complete required documentation. To undertake this unit, the learner must have a 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 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.The skills and knowledge described in this unit may, in some jurisdictions, also require a licence or permit to practice in the workplace subject to regulations for undertaking refrigeration and 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.
