Product Liability

Field service technicians are authorized to make an initial 
assessment in the event of reported damages. If there are 
any questions about the process involved, the technician 
should call U-Line for further explanation.

While inspecting for defects or installation issues, photos 
should be taken to document any damages or issues found.

During the assessment, if the service technician is able to 
find the source of the damage and it can be resolved by 
replacement of a part, the servicer is authorized to replace 
the part in question. The part that caused the damage 
must be returned to U-Line in its entirety. The part must 
be clearly labeled with the serial number of the unit it was 
removed from, the date, and the servicer who removed the 
part. 

If the service technician determines the damage is the 
result of installation issues (water connection/drain, etc.), 
the consumer would be notified and the issues shall be 
resolved at the direction of the consumer.

If damage is evident and the service technician is 
unable to find the source, U-Line must be contacted at 
1.800.799.2547 for further direction.
