▪
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
2
2 equivalent.
▪
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.
1.4.2
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-
fied specialist. The operator is responsible vis-a-vis third-parties in the work area.
1.4.3
Obligations of the operators
Carefully read the operation manual before operating the temperature control unit. Please observe
the safety instructions. When operating the temperature control unit, wear appropriate personal
protective equipment (e.g. safety goggles, protective gloves, non-slip shoes).

General information
1.5.1
Description of workstation
The workstation is located at the control panel in front of the temperature control unit. The work-
station is determined by the customer's connected peripheries. Accordingly, it must be designed
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.

Optional at the choice of the manufacturer.
▪
Temperature control units with heating correspond to class number III/FL. These temperature
control units are characterized by an “H” in the device name.
▪
Temperature control units without heating correspond to class number I/NFL.
