9. WARRANTY, SERVICE & RETURNS 

The industrial grade housing and quality construction of the Mackenzie OPM-3SM virtually 
eliminates the need for service or maintenance. There are no user-serviceable components 
within the Mackenzie OPM-3SM. Refer all servicing to the factory. 

9.1 Warranty Coverage

The Mackenzie OPM-3SM is tested and checked before shipment and is guaranteed 
against defective material or workmanship for a period of one (1) year from the date of 
purchase. Should trouble ever develop, contact the Factory directly by telephone or in 
writing. If it is determined that the equipment requires Factory service, return it to the 
Factory. If our inspection shows that the trouble was caused by defective material or 
workmanship, we will repair or replace the equipment without charge and return 
prepaid. Repairs made necessary by abuse, improper use, unauthorized service or 
maintenance, and/or improper installation, as well as out of warranty repairs, will be 
charged at our regular repair prices in effect at the time. The obligation under this 
warranty shall be limited to the replacement, repair or refund of any such defective 
device within the warranty period, at Mackenzie’s discretion. 
 
This warranty is in lieu of and excludes all other warranties, expressed or implied, and 
in no event shall MACKENZIE be responsible for damage to other equipment or 
property, for any anticipated profits, consequential damages, loss of item, or other 
operation or use of this product, and MACKENZIE’S maximum liability shall not ever 
be greater than the price paid for the equipment. This warranty gives you specific legal 
rights. Your rights may vary from state to state. Inquiries regarding use, repair and 
service should be made to:

address at no cost to you within the USA. Repair or replacement of your OPM-3SM 
system at our factory is your exclusive remedy.
