General warnings

-Using the unit without observing the manufacturer's instructions may alter the appliance's safety requirements. 

-  Detectors  should  be  installed  in  a  place  protected  from  vibrations,  water  and  corrosive  gases,  where  the  ambient 

temperature does not exceed the value indicated in the technical data. 

-  Detectors  supervise  a  point  and  not  an  area.  If  the  gas  leak  does  not  reach  the  sensor,  or  the  level  of 

concentration  in  that  point  does  not  reach  the  alarm  values,  no  alarm  will  be  activated.  If  perimeter 
supervision is required, several sensors should be installed around that area.

Working conditions:

-Keep the detector work environment free of chemical agents (such as solvent, paints, alcohol, acetone, silicone, etc.), and 

free of engine fumes or gases from fermentations (bread, pizza) or ripening (breathing) of fruits.

-The detector should generally be installed in an area of potential concentration/accumulation of gas, in low positions (due 

to the greater relative density, in relation to air, of the gases subject to detection).

-The 

AKO-57624

 refrigerant gas detector may only be used in locations that have not been classified with risk of explosion. 

-Reference regulations: EN 378
-Applicable local regulations: Compliance must be ensured
