FIELD OF APPLICATION 

 
The head is designed to be used with water up to 90 °C, with addition of mild detergents or disinfectants. In case of 
use  with  special  or  even  flammable  liquids  (different  viscosity,  chemical  harshness  or  other),  please  contact  our 
technical  department.  The  head  shall  be  used  within  pressure,  temperature  and  RPM  speed  limits  reported  in  the 
official  documents,  such  as  declaration  of  conformity,  certificate  of  assembly  and  technical  data  reported  on  the 
instruction manual. 
 
The cleaning liquid shall have an ignition temperature of minimum 50  K over the maximum exterior temperature of 
the appliance’s surface where the cleaning liquid is utilized. 
 
The ambient temperature when the appliance is working shall range between  0 ÷ +90 °C. For a different use, please 
contact the manufacturer for a customized study. 
 
Only  when  it’s  used  according  to  the  prescriptions  included  in  this  manual  and  in  correctly  tackling  residual  risks 
raising from its use, does this head assure a level of protection high enough as to not generate potential sources of 
priming, when installed in a potentially explosive environment. 
 
The appliance in question grants that potential sources of priming are not activated in normal functioning and even in 
case of foreseeable and rare failure or malfunction.  
 
Breakage  or  failure  to  the  appliance  can  happen.  In  that  case,  it  is  necessary  to  check  the  causes  of  failure.  When 
these are traced down to the appliance, they must be removed.  
 
Note 1: the appliance reaches a maximum surface temperature according to the temperature of the fluid pumped in. 
The temperature class must take into account the safety factor 0,8 aimed for appliances of class 1, see table below.

Note 2: the cleaning liquid is to be chemically compatible with the seals that have been assembled by the manufacturer 
of the appliance. The marking will identify the material of the seals, as per the following chart:

Compatibility (category - zoning) between the head and the environment must be established by the user according to 
exact and specific considerations Directive 99/92/EC. 
 
It is not allowed to use the heads in potentially explosive atmospheres in underground and mining areas, EPL Ma and 
Mb (group I category M1 and M2).
