Rating plate
The humidifiers can be identified by the rating plate placed on the partition in the electrical cabinet.
There is also a label showing the types of gas allowed for each country and the corresponding supply
pressures (classification according to EN437).
Note: tampering, removal or absence of the rating plate or anything else that does not allow certain
identification of the product will make any installation or maintenance operations difficult.
