Servicing R290 units
Servicing R290 units requires a different level of expertice and knowledge than what is required to install the systems.

You may also require specific qualifications depending what tasks you carry out during the Ecodan service.
Expertise & Knowledge

Qualifications
Qualifications - Specialist F-Gas qualification will be required if you need to break into the refrigeration circuit.
This would be required if you need to replace the compressor, reversing valve, high pressure switch or any other component within the refrigerant circuit. However, it would be very rare Mitsubishi would ask you to carry out these tasks on site.
