Recover, pressure test, evacuate, charge and leak test refrigerants - appliances

Assessment tool

Version 1.0
Issue Date: May 2024


This unit involves the skills and knowledge required to recover refrigerants, conduct pressure and leak tests, and evacuate and charge refrigerants in a self-contained appliance. This includes flammable and non-flammable refrigerants.

Competency in this unit requires the ability to work safely, prepare for and implement the recovery of refrigerants, undertake pressure and leak testing, perform evacuations and charging of refrigeration appliances as well as completing all required documentation.

Individuals will typically work independently to safely handle refrigerants used in appliances.

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 may 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 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) 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, 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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.
