F-Gas Category IV – Leak Checking
About this course:
The F-Gas category IV course is the minimum legal F-Gas qualification required by all RAC operatives who carry out leak checking on RAC & HP systems containing Fluorinated Gas or Ozone Depleting Substances, and who report refrigerant leaks for investigation and repair by a suitably qualified (category 1) technician. You will learn about the different refrigerants. This course does not include safe handling of refrigerants .
If you are not familiar with refrigeration science and principles, or function of components in the vapour compression system or Pressure Enthalpy (pH charts) we recommend you attend the 5 day course where greater knowledge and practical training will be provided.
Duration: (contact us for a self assessment form to identify the duration you require)
