2079 F-Gas Combination (Unit 101 & 102)

Course Overview

City and Guilds 2079 F-Gas Regulations (Category I)

All engineers required to handle HFC refrigerants must now hold this new European F-Gas qualification

This 4½ day course is designed for a selective group of experienced installation, service and maintenance engineers whom already hold the current 2078 Safe Handling of Refrigerants certification or other qualifications recognised in the current refrigeration / air – conditioning industry. These may include NVQ 6007 – 6017 -6087. The objectives of the course are to combine both the Knowledge and Practical assessment process as required for certification to City and Guilds 2079 F-Gas Regulations.

Course Content

Instruction is given in all aspects of the basic principles and operational efficiency underlying refrigeration / air conditioning systems in preparation for the GOLA multi choice knowledge assessment. Subjects covered include:

  • Standard SI units of measurement.
  • Basic theory of refrigeration, use of pH diagrams, function of components, condition of refrigerant within the circuit and system operation conditions.
  • System monitoring and indications of leakage.
  • The effects of HFC’s and HFC systems on the environment and energy efficiency.
  • Equipment record requirements.
  • Potential leakage points.
  • Handling of contaminated refrigerant and oil.
  • Leakage risks of system components
  • Knowledge of HCFC refrigerants and their environmental effects.   


  • Brazing of joints in copper pipe-work for installation into a system.
  • Strength testing of pipe-work prior to installation.
  • Tightness testing of system.
  • Evacuation & Dehydration of system.
  • Charge a zeotropic blend into a system. Determine charge weight sufficient by readings,
  • “Indirect” leak checking & “Direct” leak checking using electronic leak detector.
  • Recovery of refrigerant from the system.
  • Draining and correct disposal of oil from a system compressor.
  • Completion of all certificates and records required throughout operations.

Additional Information

Successful completion will involve an On-line Knowledge assessment and Centre Observation of Practical competency.
