5.  For  any  defects  due  to  the  misuse  or  any  reasons  detailed  in  par.  5,  the  Purchaser/Warranty 

Beneficiary will be charged any expenses incurred for their repair. 

6.  Warranty does not cover: 

  damage  or  failure  due  to  the  misuse,  user  interference,  failure  to  inspect  or  maintain  the 

device  as  laid  down  in  "SERVICING  AND  MAINTENANCE"  of  this  Operation  and 
Maintenance Manual; 

  device  damage,  other  than  caused  by  „MERCOR”  S.A.,  in  particular  caused  by  random 

events,  e.g.  driving  rain,  flood,  hurricane,  flooding,  lightning  strike,  mains  overvoltage, 
explosion,  hale,  airplane  crash, fire, avalanche,  soil creep  and  secondary  damage  due  to 
those events. Driving rain has a run-off coefficient of at least 4, as defined by the Institute of 
Meteorology  and  Water  Management.  If  the  run-off  coefficient  cannot  be  determined,  the 
factual circumstances and actual damage on site will be considered, indicating driving rain.  
Hurricane has a wind speed of at least 17.5 m/s (damage is considered as being caused by 
the hurricane, if the hurricane was identified in the nearest vicinity); 

  damage due to the failure to notify about any identified defect;  

  coating quality deterioration due to the natural ageing; 

  defects due to the use of abrasive or aggressive cleaning agents; 

  damage due to the aggressive external factors, in particular, chemical and biological factors 

arising from the production processes and activities on site or in the vicinity of the device; 

  natural wear and tear (e.g. gaskets), unless an inherent defect was identified; 

  damage due to the incorrect transport, unloading and storage; 

  damage  due  to  the  failure  to  follow  the  installation  instruction  in  the  Operation  and 

Maintenance Manual and good practices; 

  devices or their components if the data plate or any warranty seals are removed or broken. 

7.  Warranty claims should be made to „MERCOR” S.A. within 7 days from the date the defect was 

identified.   

8.  Warranty  claims  can  be  made  at:  phone:  58/341-42-45,  fax:  58/341-39-85,  e-mail:

section "SERVICING AND MAINTENANCE".  

10.  The warranty is voided immediately in case of: 

  Structural  modifications  of  the  device  by  the  Purchaser/Warranty  Beneficiary  without 

„MERCOR”  S.A.  approval,  failure  to  carry  out  periodical  inspections  and  maintenance  as 
scheduled, by unauthorized personnel or by a service centre not authorized by „MERCOR” 
S.A. or device misuse and modifications by unauthorized personnel other than required in 
normal device operation. 

11.  The warranty guarantee of „MERCOR” S.A. does not apply in the cases specified in section 10.  
12.  A precondition for the repair is to provide access, in particular access to the room the devices are 

installed  in  and  all  the  cleanouts,  remove  thermal  insulation,  suspended  ceilings  and  other 
systems preventing access to the device etc. 
 

To all matters not settled herein provisions of the Civil Code shall apply.
