rev 09.2017 - ©STULZ S.p.A. - all rights reserved 

In the warranty period, the components and/or machines are produced under "Warranty pending control" 
except for consumables (for example:  mechanical seals for hydraulic pumps, transmission belts, filters, etc) 
for which Stulz S.p.A. does not grant any warranties. 

 

 

For each defective part, during the warranty period, Stulz S.p.A. will, at its sole discretion, repair or replace 
it  at  its  plant  or  at  the  company  if  authorised.  If  the  warranty  is  granted,  Stulz  S.p.A.  will  solely  bear  all 
costs  for  the  defective  components,  the  manpower  to  make  the  repair  and  the  transportation  costs  to 
deliver the unit or components repaired/replaced to the client.

 

  

 

 

If the Client expressly requests an intervention at its offices, Stulz S.p.A. will not be the responsibility of the 
staff  transfer  costs  that  will  be  billed  based  on  the  Stulz  S.p.A.  rates  set  forth  in  the  request  document, 
which can be viewed on the "Technical Assistance" page at 

www.stulz.it

 

 

If agreed with Stulz S.p.A., the replacement part will be sent at the expense of the client. Stulz S.p.A. will 
issue the sales order FOB. The component declared to be defective must be returned to Stulz S.p.A. within 
40  days  from  receipt  of  the  replacement  part  with  the  client  transporting  the  part.  In  the  case  where, 
analyzing  the  delivery,  the  client  is  not  responsible  for  the  defect,  Stulz  S.p.A.  will  credit  the  previously 
billed replacement part. In the case where the component is not defective, it will be kept definitely by Stulz 
S.p.A. and will be charted minus 10% of its value and with a minimum expense of €25. 

 
In the case where, following the analyses conducted by Stulz S.p.A. or by the subject appointed, the client is 
responsible for the defect, all costs incurred, including any charges by suppliers for component controls and 
repairs including any shipping costs will be billed to the Client. 
 
Stulz S.p.A. will not be liable for all expenses that occur, such as, for example, the removal, installation and 
handling of the unit and the material shipping costs to Stulz S.p.A. All expenses not covered by Stulz S.p.A. 
but incurred by it will be charged to the Client. 

 

Stulz S.p.A. provides a warranty period equal to six months from which the components were replaced and 
repaired. 

 

At the end of the warranty period, the products repaired and replaced do not modify the start and end time 
for the warranty.  
 
Stulz S.p.A. applies the aforementioned conditions for units that breakdown at start up. 
 
 
 

 4.2 STULZ / COSMOTEC PRODUCT DELIVERY TO STULZ S.P.A.

 

The delivery to Stulz S.p.A. must be previously authorised by assigning an authorization code to the delivery 
to be made to the transportation document. 
The authorization code for the delivery is requested from Stulz S.p.A., exclusively by direct clients, by filling 
out the "Delivery Request/Technical Assistance" form in detail. 

   Remember that: 
 

 

 The transportation costs for returned merchandise is at the client's expense. Stulz S.p.A. will not pick up 
material delivered with the transportation costs at its own expense. 

 

The material must be delivered with transportation documents on which the delivery authorization code is 
cited.  In  the  case  where  a  courier  is  used  that  handles  the  pick-ups  through  delivery  slips,    insert  the 
transportation document in the package or affix it to the package.  

 

The  merchandise  acceptance  warehouse  will  not  accept  material  without  an  authorization  code  for  the 
delivery cited on the transportation document or in a clear manner on the package. 

 

The delivery credited for the incorrect order or lack of sale by the client are subject to economic deductions 
to cover the control, lay  out and  administrative costs  incurred by Stulz  S.p.A. that can vary based  on the 
conditions  of  the  merchandise  delivered.      The  minimum  deduction  amount  is  equal  to  15%  of  the  asset 
value. 

 

Stulz S.p.A. will charge the client €5- as the delivered unit control costs for repairs outside of the warranty 
if the repair estimate is rejected. At the client's request, Stulz S.p.A. will dispose of the unrepaired delivery, 
charging €25. When it receives this request, Stulz S.p.A. will send an authorization form for the disposal 
that the client will fill out and sign.
