 Safety

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

  (

AT

mospheres 

EX

plosibles) 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. 

WARNING • 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 sur-
face of the compressor must be avoided with certainty (e.g. 

pneumatically moved dust, flowing fluids, direct ventilation, belt 

drives, brushes, foils, etc.).

• Perform installation work only if no damage, leaks and/or 

appearances of corrosion can be recognized.
