General information
If refrigeration units are used, please comply with the rules and regulations that are
in force in the country where the system is set up.
Information concerning the refrigerant and the filling quantities can be found in the
“Technical Data” section or on the type plate of the refrigeration unit.
Note the requirements regarding the installation site according to EN 378,
"Refrigeration systems and heat pumps".
The refrigeration unit contains a fluorinated greenhouse gas (refrigerant). The
refrigerants that are used are so-called partially halogenated fluorohydrocarbons
(HFCs) without an ozone depletion potential (ODP=0). Information concerning the
refrigerant filling quantity and greenhouse potential can be found in the "Technical
Data" section.
NOTE
The pressure vessels of the refrigeration system are subject to periodic
inspections depending on the device category and in accordance with the
Pressure Equipment Directive.
•
Pressure vessels of category 1 and 2 must be tested by a competent
person.
•
Pressure vessels of a higher category than category 2 must be tested by
an approved inspection body (e.g. TÜV in Germany).
•
The device category in accordance with the Pressure Equipment Directive
is stated in the "Technical data" section.
•
Comply with the applicable national and local regulations and laws (e.g.
Pressure Equipment Directive).
Please refer to the "Technical data" section.
Note concerning the protection of the environment
Refrigerants are harmful to the environment if released into the atmosphere.
•
Work on the refrigeration unit should be performed only by personnel
qualified according to the Chemicals Climate Protection Ordinance.
