Warranty and Disclaimers 

 

WARRANTY 

 

The products described in this manual, with the exception of the O2 and pressure sensors, are 

warranted to be free from defects in material and workmanship for a period of 365 days from 

the date of shipment to the buyer.  Within the 365 day warranty period, we shall at our option 

repair such items or reimburse the customer the original price of such items which are 

returned to us with shipping charges prepaid and which are determined by us to be defective.  

This warranty does not apply to any item which has been subjected to misuse, negligence or 

accident; or misapplied; or modified; or improperly installed. 
 

The O2 and pressure sensors are considered an expendable part and as such cannot be 

covered by a warranty.   
 

This warranty comprises the sole and entire warranty pertaining to the items provided 

hereunder.  Seller makes no other warranty, guarantee, or representation of any kind 

whatsoever.  All other warranties, including but not limited to merchantability and fitness for
