1.3 Safety instructions

WARNING
The GEA refrigerating compressors named in the title are intended for installation in machines that
were set up in areas falling under the EU Explosion Protection Directive 1999/92/EC (operator direc-
tive). In the European Union, electrical as well as mechanical devices operated in explosive atmos-
pheres must fulfil what are known as ATEX (ATmospheres EXplosibles) conditions.
The compressors are specially designed for the category shown on the name plate in accordance with
the ATEX directive and may only be used in conformity with the conditions specified and documented
in the set-up area (explosion protection document). User safety is taken into account as a particular
focus of design. But it is permissible to start up the compressor only if it was installed in accordance
with these instructions and the entire system into which it is integrated has been inspected in accor-
dance with legal regulations and approved.
The declarations and remarks by GEA can only refer to the product itself. We assume that the appli-
cable regulations, standards and technical rules are followed in installation and during operation. The
plant constructor/operator must evaluate the interactions with other devices and components of the
system and with the environment, especially regarding potential ignition sources.
• Refrigerating compressors are pressurised machines and there-
fore require particular caution and care in handling.
• Risk of burns! Depending on the operating conditions, surface
temperatures of over 60 °C on the pressure side or below 0 °C on
the suction side can be reached.
• The maximum permissible overpressure must not be exceeded,
even for testing purposes.
• The compressor may be operated only if it is free of defects!
• No work may be performed when an explosive atmosphere is
present!
• Smoking, fire and open flame are strictly prohibited! Mobile tele-
phones must be switched off!
• Strongly charge-generating processes must be excluded within 2
meters. The contact of rapidly moving particles with the surface
of the compressor must be avoided with certainty (e.g. pneumati-
cally moved dust, flowing fluids, direct ventilation, belt drives,
brushes, foils, etc.).
• Perform installation work only if no damage, leaks and/or appear-
ances of corrosion can be recognized.
