so that the air flowing into the temperature control unit is not reduced (see page 83, Section
»Function check and visual inspection«). Connect the building’s exhaust system with the temper-
ature control unit’s exhaust air port. The cover of the supply air port mustnot be removed if the
exhaust system provided in a building is not used.
▪ NO gas warning sensor is installed in this temperature control unit! Make sure that the installa-
tion site of the temperature control unit is sufficiently protected in the event of malfunction.
These include:
- Installation of a gas warning sensor for the building (room monitoring).
- Permanent ventilation of the temperature control unit and/or the installation site.
- All-pole disconnection in the event of malfunction of the temperature control unit.
1.3.1.3 Temperature control units with fluorinated greenhouse gases/refrigerants
F gases regulation (EC) No. 517/2014 of April 16, 2014, on fluorinated greenhouse gases, and re-
pealing Regulation (EC) No. 842/2006.
These regulations deal with all systems that contain fluorinated refrigerants. The substances dealt
with in Directive (EC) No. 1005/2009 of the European Parliament and of the Council of 16 September
2009 that deplete the ozone layer are excluded (CFC/HCFC).
The directive regulates the reduction of the emission, utilization, recovery, and destruction of cer-
tain fluorinated greenhouse gases. It also regulates the identification and disposal of products and
devices that contain these gases. Since July 4, 2007, responsible bodies must check their stationary
refrigeration systems for leaks at regular intervals, and have any leaks eliminated immediately.
Directive (EC) No. 303/2008 contains stipulations on the training and certification of companies and
personnel that are permitted to execute the specified activities.
Obligations of the responsible bodies:
▪ Directive (EC) No. 842/2006 already imposed a number of obligations upon responsible bodies
regarding certain fluorinated greenhouse gases. The new Ordinance on Fluorinated Greenhouse
Gases upholds these to a large extent. Some duties are added while others are designed different-
ly by this new ordinance. Please refer to the text of this ordinance for a complete overview of the
individual responsible bodies.
▪ General obligation to reduce emissions.
▪ Only certified companies may maintain, repair or decommission refrigeration systems. The re-
sponsible bodies must verify that these companies are certified.
▪ Until 31.12.2016: Annual leak tests of stationary refrigeration systems by certified personnel
(such as service engineers of Peter Huber Kältemaschinenbau AG). Valid for a filling capacity of 6
kg to 30 kg of fluorinated greenhouse gases.
▪ As of 01.01.2017: Regular leak tests of stationary refrigeration systems by certified personnel
(such as service engineers of Peter Huber Kältemaschinenbau AG). The required test interval is
based on the refrigerant filling capacity and the type of refrigerant, converted to CO
2
equivalent.
▪ Responsibility of responsible bodies to recover F-gases using 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 name 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.
1.3.2 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.
