Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package.

This unit involves the skills and knowledge required to recover, pressure test, evacuate and charge refrigerants from refrigeration and air conditioning systems.

It includes recovering refrigerants, pressure testing, evacuating, charging refrigerants into refrigeration systems and completing documentation.

The skills and knowledge in this unit will be applied by refrigeration and air conditioning technicians during the recovery and charging of refrigerants on refrigeration and 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 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.

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.

Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all the requirements of the elements and performance criteria on at least two separate occasions and include:

• applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, including using risk control measures
• charging the system with the correct type and quantity of refrigerant
• completing necessary documentation
• documenting work, including refrigerant usage and removal
• evacuating a system to required level
• following manufacturer specifications and manuals
• implementing relevant legislation, industry standards, codes of practice and regulations
• performing a vacuum test
• pressure testing a system to design conditions
• recovering refrigerant from a system
• testing the system for leaks and rectifying as necessary.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all the requirements of the elements and performance criteria and includes knowledge of:

• evacuation and dehydration, including vacuum pump types, use and care, suitable vacuum measuring instruments, drop testing and evacuation methods, including triple and deep
