Caution 

This symbol and signal word refer to a potentially 
hazardous situation which could result in damage 
to the equipment if ignored. 

 

Info 

This  symbol  indicates  useful  information  and 
recommendations  as  well  as  measures  that  will 
prolong the value of your measuring and control 
system. 

1.2  Intended use of the device 

Use these installation and operating instructions, the identification on the rating 
plate  (see  5.6)  and  the  technical  data  sheet  to  check  whether  the  device  is 
suitable  for  the  intended  use/application.  The  device  complies  with  the 
requirements of the European Pressure Equipment Directive 2014/68/EU. 

 

The device may only be used to indicate fill levels on containers. 

The maximum values of the pressure and temperature range of the device must be checked 
before  installation.  If  the  maximum  allowable  operating  values  of  the  device  are  lower  than 
those of the system on which it is to be installed, protective instruments for the device, such 
as pressure reducers or similar, must be provided to avoid limit situations.  The device may 
only be used in accordance with the information in these installation and operating instructions 
or  for the parameters and applications agreed in the supply contract. (see rating plate, 5.6) 
The  operator  of  the  direct  water  level  indicator  is  obliged  to  familiarise  himself  on  the 
compatibility of the medium and the device. In case of doubt, contact the relevant installation 
manager or site manager. 

The correct installation position, alignment and flow direction of the device must be observed! 
Before  installing  the  IGEMA  product  on  boilers  or  containers,  it  is  essential  to  remove  all 
protective covers and, if necessary, the protective film from rating plates and sight glasses.
