F-Gas for Cars & Light Commercial Vehicles
The qualification is for those who already have practicing in the industry, for those whose aim is to enter the industry and for those wanting to gain a certificate for their own personal skills development.
This qualification in Mobile Air Conditioning can be a first step into the vehicle-based air conditioning sector. It also helps people already working in the sector further developing their skills and gain an acknowledgement of what they already offer.
7543-01
The standalone 001 Unit (7543-01) meets the legal requirement for handing F-Gases under the MAC directive, giving licence to handle refrigerants in compliance with EU regulations (EC) 307/2008.
Following the centre provided training the qualification entails a practical assessment activity along with a range of qualification specific verbal questions.
