Before  selecting  and/or  using  a  LEUCO  product,  the  buyer  should  carefully  analyse  all  the  aspects  concerning  its  application  and 
examine in depth the information provided in LEUCO technical and commercial brochures. As LEUCO products can be used in many 
different  operating  conditions  and/or  applications,  the  buyer  is  solely  responsible  for  the  final  selection  of  the  most  suitable 
product  for  their  needs,  based  on  their  own  analysis  and  testing,  and  for  compliance  with  all  the  functional  and  safety-related 
specifications. 

 

The products and this document may be subjected to modifications by LEUCO at any time and without prior notice. 

 

The buyer shall have the installation design implemented in compliance with the instructions given in this manual, the national and 
local regulations and laws in place.
