This unit of competency defines the skills and knowledge required to test, recover, evacuate and charge refrigeration systems to achieve performance specification.

It applies to refrigeration systems associated with refrigeration and air conditioning in commercial, industrial, domestic, marine and transport applications. This unit does not apply to vehicle in-cab air conditioning systems.

Demonstration of competency must be in accordance with Australian Standards, including AS - HB40 Refrigeration and Air Conditioning codes of practice, and relevant ozone and greenhouse substance legislation.

A Refrigerant Handling Licence must be held by any person who carries out work in relation to refrigeration and air conditioning equipment.

Band: A

Unit Weight: 4

(add new lines for each of the 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.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Relevant information includes one (1) or more of the following:	manufacturers' technical data pressure temperature charts operating manuals
Appropriate corrective action includes:	isolation and tagging of faulty components, repair and/or replacement
Contamination includes one (1) or more of the following:	moisture non-condensables solids and acids
Refrigerant includes one (1) or more of the following:	chlorofluorocarbons (CFCs) hydrochlorofluorocarbons (HCFCs) hydrofluorocarbons (HFCs) natural refrigerants ammonia
Relevant codes and regulations include:	Australian Standards, refrigeration and air conditioning codes of practice, relevant ozone and greenhouse substance legislation

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
