None of the above warranties cover damage caused by improper use or maintenance, accidents, acts of God or minor

the only warranties applicable to the Excelight products listed in the "Specific Warranty Coverage" section. These limited 
warranties outline the exclusive remedy for all claims based on a failure of or defect in any of these products, whether the 
claim is based on contract, tort (including negligence), and strict liability or otherwise. These warranties are in lieu of all

Pro-Rated Warranty 

The pro-rated warranty as specified in this document is applicable according to following parameters: 
All the warranties are 100 % valid at the time of the sale, and effective the day of the registration of the warranty. The 
decrease in covered percentage occurs the day after the anniversary date of the purchase of the UV System (as long as 
the warranty has been registered and valid). The prorated portion of an eligible warranty repair is based on the date that 
the problem is communicated to the dealer in writing, or of the day when the UV System enters the dealer and/or Waterite, 
Inc. for repairs, or the date determined by the dealer (subject to Waterite, Inc.’s approval). If during a repair started at a 
higher prorated percentage, a second repair is requested or necessary and is under warranty at a lower proportion, the 
lower proportion will be applicable. The fact of not having registered the warranty will not prolong in whole or in part the 
warranty, the starting date of your warranty is always the date of purchase.
