1.4  Safety instructions for this device 

These installation and operating instructions are an integral part of the device 
and  must  be  forwarded  to  the  responsible  departments  "Goods  inward, 
Transport, Installation, Commissioning and Maintenance". They must be kept in 
such a way that the technical staff have access to these documents at all times. 
If  the  device  is  passed  on  to  a  third  party,  these  installation  and  operating 

 

instructions must also be included in the national language of the third party. 

Avoid  shocks  and  hard  contact  during  transport,  as  this  can  lead  to  damage.  During 
intermediate storage, the device must be kept dry and secured against damage. 

When  servicing  the  unit,  make  sure  to  use  sharp-edged  internal  parts  and  avoid  shards  of 
broken  glass.  There  is  a  risk  of  cutting  hands  and  arms!  Always  wear  work  gloves  when 
changing packing, valve seat and valve plug.  

For units with a dead weight of 30 kg or more, the customer must provide adequate support 
(e.g. via a spring suspension device, etc.). This can be attached to the holding strap/eyelet on 
the device. 

When  returning  goods  to  IGEMA  GmbH,  the  applicable  safety  and  environmental  laws 
according  to  GGVSEB  [German  ordinance  on  the  national  and  international  carriage  of 
dangerous goods by road, rail, and inland waterways] must always be observed. If there are 
any risks to health or the environment due to residues or the device has a mechanical defect 
this must be indicated when returning the device and the necessary precautionary measures 
must be taken. If the returned goods are devices that have come into contact with or contain 
hazardous substances, a safety data sheet must be enclosed, and the goods must be clearly 
marked.  In  addition,  the  hazardous  substance  must  be  reported  to  the  logistics  service 
provider. 

 

Darauf achten, dass die im Gerät eingebrachten Permanentmagnete in der 
Magnetisierung nicht verändert werden! 
Magnetfelder im Nahbereich der Geräte ausschließen! 

 

1.5  Exclusion of liability 

IGEMA  GmbH  Mess-  und  Regelsysteme  will  assume  no  liability  if  the  above  regulations, 
instructions and safety precautions are not observed and followed. If they are not expressly 
listed in the installation and operating instructions, changes to an IGEMA device are carried 
out at the risk of the user. 

Der  Magnetsperrschalter  darf  nicht  geöffnet  werden.  Eine  Verletzung  des 
angebrachten Siegels schließt jegliche Gewährleistung aus.
