Evidence shall show that knowledge has been acquired of safe working practices and verifying compliance and functionality of refrigeration and air conditioning installations. All knowledge and skills detailed in this unit should be contextualised to current industry practices and technologies. KS01-EJ109A Refrigeration and air conditioning installation functionality testing and verification methods Evidence shall show an understanding of refrigeration and air conditioning installation functionality testing and verification methods, applying safe working practices and relevant Standards, Codes and Regulations to an extent indicated by the following aspects: T1 Refrigeration and air conditioning installations, testing and verification methods Mandatory testing and verification requirements. Optional testing and their appropriate use Testing techniques Visual inspection methods T2 Electrical safe working practices Hazards associated with low-voltage, extra-low voltage and high-currents Arrangement of power distribution and circuits in an electrical installations Risks and control measures associated an electrical system and equipment that operate at low-voltage and extra-low voltage, and where high-currents are likely. Risks and control measures associated fault finding, maintenance and repair. Isolation and tagging-off procedures. Risks, restrictions and control measures in testing live. Risks and control measures associated with harmful dusts and airborne contaminants. Note: Sources include thermal insulation, fibrous cement materials and asbestos and other fibre reinforced switchboard materials. Safety, selection, use, maintenance and care of test equipment: Safety characteristics of electrical testing devices, Safe use of electrical testing device, and Checks and storage methods for maintaining the safety of testing devices. T3 Refrigeration and air conditioning safe working practices Hazards and risk control measures associated with refrigeration/air conditioning components and systems Harmful effects of refrigerants Control measures for the use, handling and storage of refrigerants Risks associated with modifying refrigeration/air conditioning installations, fault finding, maintenance and repair. Control measures before, while and after working on refrigeration/air conditioning components and systems. Safety, selection, use, maintenance and care of test equipment encompassing: Safety characteristics of refrigeration/air conditioning testing/measuring devices, Safe use of testing/measuring device, and Checks and storage methods for maintaining the safety of testing/measuring devices. |
