UEERA0067 — Repair and service secondary refrigeration systems

1 Prepare to service secondary refrigeration system

• 1.1Type of secondary refrigeration system components and operation are identified
• 1.2WHS/OHS requirements and workplace procedures and safety data sheets (SDS) are identified and risk control measures implemented, including wearing personal protective equipment (PPE)
• 1.3Safety hazards not previously identified are assessed, documented and risk control measures devised and implemented
• 1.4Extent of faults is determined from reports, documentation, observation and discussions with appropriate person/s
• 1.5Appropriate person/s is consulted to ensure the work is coordinated effectively with others involved on the worksite
• 1.6Tools, equipment and testing devices needed to carry out refrigeration work are obtained in accordance with workplace procedures and checked for correct operation and safety

2 Carry out secondary refrigeration maintenance requirements

• 2.1WHS/OHS requirements, regulations, workplace procedures and risk control measures are followed
• 2.2Components are checked and isolated in accordance with WHS/OHS requirements and procedures
• 2.3Refrigeration maintenance tests are performed on the primary cooling source, operating pressures, operating current, refrigerant charge, secondary flow rates and condenser cooling system, and system faults or non-compliance documented to operational specifications
• 2.4Refrigeration operational maintenance tests are performed on the secondary refrigerant pumping/circulation devices, pressure and flow rates recorded, and faults or non-compliance to system specification documented
• 2.5Chemical integrity, including the dilution rate, anti-bacterial and anti-corrosion rates of the secondary refrigerant, is checked using test kit and following approved WHS/OHS procedures, including PPE, and results or non-compliance are documented
• 2.6Secondary refrigerant pipe work is checked for leaks and stability and its insulation is checked for soundness
• 2.7Refrigeration system components, evaporators, blowers, other heat exchangers, heat recovery or defrost systems are checked for correct operation and cleanliness
• 2.8Control system operation, including safety controls and any faults or non-conformity to system specifications are documented in accordance with WHS/OHS guidelines and workplace practices

3 Repair secondary refrigeration system

• 3.1Justification for solutions used to solve refrigeration system problems is documented in accordance with workplace procedures
• 3.3Repair work is documented and appropriate person/s notified in accordance with workplace procedures
• 3.4Repairs to refrigeration system components are performed to achieve compliance to design operation and manufacturer recommendations for effective operation
• 3.5Refrigeration control system are adjusted, as required, to achieve compliance to design operation and manufacturer recommendations for effective operation
• 3.6Record of flows, pressures and temperatures obtained before and after repair are compared to refrigeration specifications and contingency measures implemented, as required, to ensure compliance to design operation and manufacturer recommendations for effective operation

4 Complete reports on refrigeration maintenance and repair activities

• 4.1Work area is cleaned and made safe in accordance with workplace procedures and practices
• 4.2Refrigeration service/maintenance and repair activities on secondary refrigeration system and relevant non-compliance specification after repair are documented and reported to appropriate person/s

What does an assessment tool for UEERA0067 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEERA0067 needs to address all 59 unit components: 4 elements with 21 performance criteria, 10 performance evidence requirements, 28 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for UEERA0067?

Auditori pulls the current release of UEERA0067 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for UEERA0067 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing UEERA0067 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of UEERA0067, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
