Application

This unit of competency defines the skills and knowledge required to install split air conditioning systems and associated pipework up to 18 kW cooling capacity.

This unit refers to plug in applications only. Where the installation and connection to mains supply of fixed wiring is necessary then this work must be undertaken by a suitably licensed person.

Where commissioning and decommissioning of split air conditioning systems is required see unit MEM18084 Commission and decommission split air conditioning systems.

Some jurisdictions may require the holder of this unit to be licensed or certified and users should check with the relevant authorities.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications, drawings, customer requirements, regulatory and legislative requirements for installing plug in split air conditioning systems and associated pipework up to 18 kW cooling capacity

preparing the installation site for installing unit components to manufacturer requirements, standards, codes and regulations

using tools and equipment to prepare and join pipework to specifications

ensuring pipes are run separately and insulated to specifications and relevant standards, codes and regulations

checking the installed system for compliance and integrity using appropriate testing methods and test equipment.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

basic vapour compression cycle operating principles

basic reverse cycle operating principles

layouts, siting and set-ups of split air conditioning systems

typical work environment, demands and considerations

effective communication with appropriate persons and typical problems, contingencies and solutions

components, accessories and fixtures for split air conditioning systems

considerations for siting units and components and techniques and processes for site preparation

fixing methods, tools and equipment for system components and pipework

applicable legislative requirements, standards, codes and licensing requirements for installing system components, interconnecting wiring and connection to power supply

applicable procedures for storage, handling and treatment of ozone depleting and synthetic greenhouse gas refrigerant

sustainable energy practices for the efficient use of materials and for minimising damage/contamination to environment

tools and equipment used for fabricating pipework

pipe preparation and joining techniques including cutting, flaring, swaging and bending

brazing/silver soldering techniques, equipment and consumables

dry nitrogen being used during all brazing/silver soldering work

procedures and equipment for checking pipework integrity and compliance to specification

procedures for reporting non-conformances

required documentation and procedures to complete and process.

Assessment Conditions

Assessors must:

have vocational competency in installing split air conditioning systems and associated pipework at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
