NOTE 
For the analyzers ZO23 and Fidas24 the information contained in the 
sections "ZO23: Preparation for Installation" or "Fidas24: Preparation for 
Installation (see page 29)" must be considered in addition.  
Requirements for the installation site 
The gas analyzer is only intended for installation indoors. 
The max. altitude of the installation site may not exceed 2000 m above 
sea level. 
The installation site must be stable enough to bear the weight of the gas 
analyzer! 
To ensure safe installation and removal, we recommend that the 19-inch 
housing is supported in a cabinet or rack with slide rails! 
Short gas paths 
Install the gas analyzer as close as possible to the sampling location. 
Install the gas conditioning and calibration modules as close as possible 
to the gas analyzer. 
Adequate air circulation 
Provide for adequate natural air circulation around the gas analyzer. 
Avoid heat build-up. 
Mount (see page 68) several 19-inch housings with a minimum spacing of 
1 height unit 
between housings. 
Protection from adverse conditions 
Protect the gas analyzer from: 
 Cold 
  Exposure to heat from e.g. the sun, furnaces, boilers 
 Temperature variations 
 Strong air currents 
  Accumulation of dust and ingress of dust 
 Corrosive atmospheres 
 Vibrations
