Warranty

SPECIAL WARRANTY PROVISIONS:

 The standard warranty contained in seller’s 

standard conditions of sale, as set forth in Price Sheet 150, applies to S&C BankGuard 
Plus Controls, except that the first paragraph of said warranty is replaced by the following:

(1) General:

 Seller warrants to immediate purchaser or end user for a period of 10 years 

from the date of shipment that the equipment delivered will be of the kind and qual-
ity specified in the contract description and will be free of defects of workmanship 
and material. Should any failure to conform to this warranty appear under proper 
and normal use within ten years after the date of shipment the seller agrees, upon 
prompt notification thereof and confirmation that the equipment has been stored, 
installed, operated, and maintained in accordance with recommendations of the seller 
and standard industry practice, to correct the nonconformity either by repairing any 
damaged or defective parts of the equipment or (at seller’s option) by shipment of 
necessary replacement parts. The seller’s warranty does not apply to any equipment 
that has been disassembled, repaired, or altered by anyone other than the seller. This 
limited warranty is granted only to the immediate purchaser or, if the equipment is 
purchased by a third party for installation in third-party equipment, the end user of 
the equipment. The seller’s duty to perform under any warranty may be delayed, at 
the seller’s sole option, until the seller has been paid in full for all goods purchased 
by the immediate purchaser. No such delay shall extend the warranty period.
