Safety instructions

The safety instructions are to be observed by all persons working on the system. The rules and regulations for accident prevention applicable to the place of use are to be observed. The instruction of the operating and maintenance personnel on system safety must be documented.

Please pay special attention to this chapter to avoid accidents.

All measures and specifications in the safety data sheets must be implemented and observed.



Gas leaks

If gas escapes on the product, contamination of persons, fires or explosions or the displacement of atmospheric oxygen can occur! Serious or fatal injuries are possible.

  1. Do not place pipelines and fittings under mechanical stress. Never use pipelines and components as climbing aid or to secure other parts!
  2. In the event of leaks, immediately secure the affected area!
  3. Smoking and naked flame are strictly prohibited!



Intended use

Operation of the product with gases other than those specified or outside the limits may result in dangerous reactions in the system. Incorrect use poses considerable risks to operating personnel and the environment!

  1. Only use the product for gases for which it was designed.
  2. Only use the product in the specified limit values for pressure and withdrawal quantity.
  3. Usage for another type of gas or outside the limit values is prohibited and constitutes misuse.



Defective product

A defect on the product can result in unforeseeable operating conditions. Persons may be injured.

  1. The product may only be operated in technically perfect condition in compliance with all chapters of the user manual.
  2. Environmental protection laws and safety regulations must be observed.



Displacement of atmospheric oxygen

In the event of inert gas leaks, displacement of atmospheric oxygen may occur. Danger of suffocation!

  1. The operator must ensure adequate ventilation and airing in all rooms with gas installations and monitor the oxygen content.




If the product is not used as intended, unpredictable operating conditions may occur. Serious personal injuries are possible.

  1. Repairs may not lead to a change in function. The system may not be tampered with or modified.
  2. Before each repair, the system must be depressurised and flushed through.
  3. Repairs are only permitted to be carried out by trained persons.



Incorrect operation

Incorrect operation of the system, e.g. due to instruction errors, can lead to personal injury or damage to the system.

  1. Access to the user manual by the operating and maintenance personnel must be absolutely ensured at all times.
  2. A copy of the system documentation including the user manual must therefore be kept either on the system or in a suitable and accessible location.



Working on the product

If an accident occurs when working on the product, there is a considerable risk of injury.

  1. Never work on the product unattended or unannounced.
  2. Observe the site safety rules and permission procedure.




Incorrect maintenance or maintenance work performed at the incorrect time can result in damage to the system or injury to persons.

  1. To avoid static charges, do not clean the product using dry cloths. Use damp cotton cloths.
  2. The maintenance intervals are to be specified by the system operator as part of its risk assessment.
  3. Observe the maintenance intervals and maintenance guidelines from the manufacturer and the applicable guidelines.
  4. Components may only be replaced by spare parts of the same design. The specifications of the component manufacturers must be complied with during installation.



Pressure relief lines

Discharge of hazardous media at the end of a pressure relief line or exhaust air line.

  1. Pressure relief lines may not end in areas where the escaping process gas poses a hazard to persons or the environment.
  2. The position of the pressure relief line must be carefully checked taking into account the material properties, main wind direction and other conditions.




Incorrect switching actions or confusion can occur due to inadequate lighting.

  1. Ensure sufficient lighting in accordance with the statutory regulations.
