City and Guilds 2079 -11, 12, 13 & 14 Refrigerant Handling,
Category I, II, III & IV
The Hall Training Centre is approved by City and Guilds to assess candidates for the C&G 2079 (Level 2 Award in F-Gas and ODS Regulations).
The qualification meets the competence and training requirements of UK and EU regulations and is aimed at any individual that does, or will, work with stationary refrigeration, air conditioning and heat pump equipment.
All engineers who handle HFC refrigerants must now have this qualification
(or CITB equivalent).
All engineers who currently hold Safe Handling 2078 must up-date to the new
EU 2079 in Safe Handling by July 2011
The qualification requires successful completion of an online assessment to check for under-pinning knowledge and a practical skills test.
Knowledge Assessment for Categories I & II
The multiple choice knowledge assessment is done online using the City & Guilds GOLA (Global On Line Assessment) facility at our premises in Gravesend.
The assessment includes topics on:
- Standard units of measurement
- Basic theory of refrigeration, use of pH diagrams, function of components, condition of refrigerant within a refrigeration system and operating conditions
- System monitoring and indications of leakage.
- The effects of HFCs and HFC systems on the environment and energy efficiency.
- Equipment record requirements
- Potential leakage points
- Handling of contaminated refrigerant and oil.
- Function of system components and their associated leak risk
- Knowledge of HCFC refrigerants and their effect on the environment
Knowledge Assessment for Category III
The assessment includes topics on:
- The effects of HFCs and HFC systems on the environment.
- Equipment record requirements.
- Handling of contaminated refrigerant and oil.
- Knowledge of HCFC refrigerants and their effect on the environment.
Knowledge Assessment for Categories IV
The assessment includes topics on:
- SI units of measurement
- The effects of HFCs and HFC systems on the environment and energy efficiency.
- System monitoring and indications of leakage.
- Potential leakage points
- Equipment record requirements
- Function of system components and their associated leak risk
- Knowledge of HCFC refrigerants and their effect on the environment
Candidates will be given guidance on online assessment procedure prior to the assessment.
Practical Assessment for Categories I & II
- Braze a joint in a test-piece, install into the system
- Carry out strength test & leak test on the system checking for leaks
- Evacuate the system.
- Charge a zeotropic blend into the system. Visually inspect the system for leaks.
Determine whether the charge is correct & leak test using an electronic leak detector.
- Connect & disconnect gauges on a running system with minimal refrigerant loss.
- Recover refrigerant.
- Drain oil from a compressor.
- Complete all necessary records.
Practical Assessment for Categories III
- Connect & disconnect gauges on a running system with minimal refrigerant loss.
- Recover refrigerant.
- Drain oil from a compressor.
- Complete all necessary records.
Practical Assessment for Categories IV
- Visually inspect the system for leaks, determine whether the charge is correct & leak test using an electronic leak detector.
- Connect & disconnect gauges on a running system with minimal refrigerant loss.
- Carry out indirect leak checking
- Complete all necessary records.
Training
It is anticipated that most engineers will require some training to reach the required standard for the knowledge and practical assessments. Our courses are designed with this in mind, obviously the more experienced the less training will be required. Hall Training has developed a “Flow Chart” from which entry levels can be followed and course selection made.
