TRANSPORT, STORAGE AND HANDLING 

 

 
 
Transport 
Carraro  DS  desuperheaters  are  packed  with  the  utmost  care  in  wooden 
crates or cardboard boxes so that they are protected during handling and 
transport  to  their  place  of  installation.  The  connections  are  protected  to 
prevent the entry of dirt. Follow any directions marked on the packaging. 

 
 
 

 

ATTENTION! 

 

Personnel assigned to load-handling activities must take  

all the necessary safety precautions. 

 
 

Storage 
The  desuperheaters  must be  stored  in  a  dry  environment  and  protected 
against  atmospheric  conditions.  They  must  not  be  removed  from  their 
crates or packaging until immediately before installation. 
The protective materials on the connections must be left in place until the 
last  minute.  Whether  packed  or  not,  the  desuperheaters  must  not  be 
subject to violent impacts. 
Whether packed or not, the desuperheaters must always be stored in an 
upright position, i.e. never laid on one side, in order to prevent distortion 
or damage to internal components. 
 
 
 
Handling 
When  removing  desuperheaters  from  their  packaging  and  removing  the 
protective materials from the connections immediately prior to installation, 
take  the  utmost  care  to  prevent  foreign  matter  from  entering  inside  the 
desuperheater. 
 
 
 

 

ATTENTION!

 

 

   When handling desuperheaters, keep the work area clear 

 in order to prevent damage to property  

or injury to persons.
