▪ Only certified companies may maintain, repair or decommission refrigeration systems. The re-
sponsible bodies must verify that these companies are certified.
▪ Regular leak tests of stationary refrigeration systems by certified personnel (such as Huber service
engineers). The required test interval is based on the refrigerant filling capacity and the type of
refrigerant, converted to CO
▪ Responsibility of responsible bodies operating a plant to recover F-gases by certified personnel.
▪ Obligatory documentation requirement in the refrigeration system's operation manual, specifying
type and volume of refrigerant used or recovered. The responsible body must keep the records
for at least 5 years after their creation and present it to the responsible authority upon request.
▪ Temperature control units with natural refrigerants (NR) are exempt from this Directive.
▪ Please refer to the data sheet or rating plate of your temperature control unit for the quantity
and type of refrigerant.
▪ Additional information about the definition of the inspection interval can be found on our web-
site.

Requirements for operators

Work on the temperature control unit is reserved for appropriately qualified specialists, who have
been assigned and trained by the responsible body to do so. Operators must be at least 18 years old.
Under 18-year olds may operate the temperature control unit only under the supervision of a quali-

safe by the responsible body. The workstation design also depends on the applicable requirements
of the German occupational health and safety regulations [BetrSichV] and the risk analysis for the
workstation.
