Remember

It is against the law to work with F gas if you do not have the correct qualifications. You could receive a civil penalty for breaking the law.
Checkmark is fully qualified in F-gas handling. We provide a professional commissioning service. You do the preparation and physical mounting of the equipment but must not touch the refrigerant or F-gas connections.
