This unit of competency defines the skills and knowledge required to commission and decommission single head split air conditioning systems, up to 18kW, to relevant standards, codes and local regulations.

It includes the application of safe working practices, following standard procedures to pressure test, evacuate, recover, charge and perform functional checks to test system performance.

This unit refers to plug in appliances only.

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

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment task 1: [title]      Due date:

(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.
Tools, equipment and testing devices include one (1) or more of the following:	refrigeration gauge manifold Schraeder access valves; quick connect couplings, and thermometer/thermocouple temperature measuring devices analogue and digital vacuum measuring gauges digital scales refrigerant recovery unit vacuum pump electronic leak detectors refrigerant containers/cylinders
Legislative and industry requirements include one (1) or more of the following:	Commonwealth, state and territory legislation, regulations, standards and industry codes of practice The Ozone Protection and Synthetic Greenhouse Gas Legislation Amendment Bill 2003 air conditioning residential best practice guidelines (AIRAH) AIRAH flammable refrigerants fact sheets and guide state/territory and local building regulations sustainable environmental practices for commissioning and decommissioning split air conditioning
System performance includes one (1) or more of the following:	pressure temperature sub-cooling superheating evaporator coil to air temperature difference

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.
