Elements and Performance Criteria
- Undertake preventive maintenance checks/adjustment on multi stage, cascade and/or ultra-cold industrial refrigeration systems
- The temperature, pressure and properties of the multi stage, cascade and/or ultra-cold refrigeration system are checked for conformance to specification.
- The noise/vibration levels of the multi stage, cascade and/or ultra-cold refrigeration system are checked for conformance to specification.
- Preventative maintenance tasks are performed according to manufacturers' specifications using refrigeration techniques/practices.
- Undertake fault finding on multi stage, cascade and/or ultra-cold industrial refrigeration systems and components
- Repair/replace faulty components
- Faulty components are localised and malfunction is confirmed by inspection and testing using industrial refrigeration principles, procedures and safety requirements.
- The refrigerant is removed safely from the system and contained in accordance with standard operating procedures and regulatory requirements where appropriate.
- Faulty components are dismantled and repaired to manufacturers' specifications as required
- Replacement parts are selected from manufacturers' catalogues according to required specifications.
- Return to service multi stage, cascade and/or ultra-cold refrigeration systems
- Components are reassembled and tested for correct operation and assessed against specification.
- The system is charged with correct refrigerant safely and in accordance with standard operating procedures and regulatory requirements where appropriate.
- Using industrial refrigeration principles and system application techniques, correct operation of the equipment is verified.
- Maintenance records/service reports are completed by appropriate designated means.
