F-Gas compliance Leakage inspection

• Leakage inspection
  
  Systems shall be checked for leakage dependent on refrigerant charge:
  
  3kg charge and above - check at least once every 12 months.
  30kg charge and above - check at least once every 6 months.
  300kg charge and above - check at least once every 3 months.
  Hermetically sealed systems, which are labelled as such and contain less than 6kg, are exempt.
  
  Operators of equipment containing 300kg or more must install an automatic leakage detection system. These must be checked at least once every twelve months to ensure they are functioning properly.
  
  Checked for leakage means that the system is systematically checked for leakage using direct or indirect methods, focusing on those parts of the system most likely to leak. The cause of any leak will need to be recorded in the log book.
  
  A detailed definition of what constitutes a leak check will be part of legislation attached to F-Gas.
