Special requirements for the gas analyzer Model EL3020 for the measurement 
of flammable gases 
An unimpeded exchange of air with the surroundings must be possible 
around the gas analyzer from beneath (base plate) and from behind (gas 
connections). The gas analyzer must not be put directly on a table. The 
case apertures must not be closed. The distance to adjacent, built-in 
components on the side must be at least 3 cm. 
For installations in a closed cabinet, the cabinet must have adequate 
ventilation (at least 1 air change per hour). The distance to adjacent, built-
in components underneath (floor plate) and behind (gas connections) 
must be at least 3 cm. 
Special requirements for the gas analyzer model EL3040 in degree of 
protection II 3G 
Due to the low mechanical stability of the display window, the gas 
analyzer has to be installed and operated in such a way that mechanical 
damage to the display window is ruled out.
