Recover, pressure test, evacuate, charge and leak test refrigerants - split systems

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

Elements and Performance Criteria




Prepare to recover refrigerants, pressure and leak test, evacuate and charge split systems.


OHS procedures for a given work area are identified, identified, obtained and understood


Established OHS risk control measures and procedures are followed in preparation for the work.


Safety hazards which have not previously been identified are noted and established risk control measures are implemented.


The nature of the problem is obtained from documentation or from work supervisor to establish the scope of work to be undertaken.


The work is appropriately sequenced in accordance with job schedule.


Appropriate personnel are consulted to ensure the work is coordinated effectively with others involved on the work site.


Refrigerants, lubricants and cleaning materials needed for the work are obtained in accordance with established procedures and checked against job requirements


Tools, equipment and testing devices needed to carry out the work are obtained and checked for correct operation and safety


Preparatory work is checked to ensure no damage has occurred and complies with requirements.


Recover refrigerants, pressure and leak test, evacuate and charge split systems.


OHS risk control measures and procedures for carrying out the work are followed


Checks are carried out to ensure the system or component parts are isolated, when necessary, in strict accordance with OHS requirements and procedures


Machines/plant are checked as being isolated where necessary in strict accordance OHS requirements and procedures and circuits are isolated and confirmed by appropriately competent personnel


Refrigerants are removed from a split system safely into suitably labelled containers in accordance with regulatory requirements and industry practices, and any electrical work is referred to an appropriate licensed person


Precautions are taken to prevent damage to components while pressure testing the system


Pressure testing is conducted using dry nitrogen at a pressure relative to the refrigerant to be used


Leaks are located and rectified using testing methods appropriate to the system under test and in accordance with industry practices


Split system is evacuated to the required level and cleaned the system of all moisture and other containments in accordance with industry practices


A 'Drop test' is used to prove effectiveness of the evacuation in accordance with industry practice using an appropriate electronic vacuum gauge


Components lubricants are checked and maintained in accordance with manufacturer's requirements


Split systems are charged with the appropriate refrigerant in accordance with manufacturer's requirements and industry practices


Problematic situations that arise during the work are dealt with in an appropriate manner


Split systems are pressure and leak tested, evacuated and charged efficiently without unnecessary waste of materials or damage to apparatus and the surrounding environment or services and using sustainable energy practices


Complete and report refrigerants recovery, pressure and leak test and evacuate and charge work


OHS risk control work completion measures and procedures are followed


Work site is cleaned and made safe in accordance with established procedures


Contaminated refrigerant is dealt with in accordance with legislative/regulatory requirements


Completion of the work is documented and an appropriate person or persons notified in accordance with established procedures
