1.4  Intended use

1.3  General safety instructions

WARNING

Risk of accidents.

 

Refrigerating compressors are pressurised machines and as such 
call for heightened caution and care in handling.

 

The maximum permissible overpressure must not be exceeded, 
even for testing purposes.

Risk of burns! 
- Depending on the operating conditions, surface temperatures of      
  over 60°C on the discharge side or below 0°C on the suction side  
  can be reached. 
- Avoid contact with refrigerant necessarily. 
  Contact with refrigerant can cause severe burns and skin  
  damage.

WARNING

The compressor may not be used in potentially explosive 

 

environments!

These  assembly  instructions  describe  the  standard  version  of  the  compressor  named  in  the  title 
manufactured by GEA Bock. GEA Bock refrigerating compressors are intended for installation in a 
machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 97/23/EC 
Pressure Equipment Directive and 2006/95/EC – Low Voltage Directive

).

Commissioning is permissible only if the compressor has been installed in accordance with these as

-

sembly instructions and the entire system into which it is integrated has been inspected and approved 
in accordance with legal regulations.

The

 compressors are intended for use in refrigeration systems in compliance with the limits of 

application.
Only the refrigerant specified in these instructions may be used.

Any other use of the compressor is prohibited!
