WARRANTY

The manufacturer warrants the product manufactured by it, when properly installed, operated, applied, and
maintained in accordance with procedures and recommendations outlined in manufacturer’s instruction
manuals, to be free from defects in material or workmanship for a period of one (1) year from the date of
shipment to the buyer by the manufacturer or manufacturer’s authorized distributor, or eighteen months from
the date of shipment from the factory, whichever occurs first, provided such defect is discovered and brought
to the manufacturer’s attention within the aforesaid warranty period. The manufacturer will repair or replace
any product or part determined to be defective by the manufacturer within the warranty period, provided such
defect occurred in normal service and not as a result of misuse, abuse, neglect or accident.

The warranty covers parts and labor for the warranty period. Repair or replacement shall be made at the factory
or the installation site, at the sole option of the manufacturer. Any service performed on the product by anyone
other than the manufacturer must first be authorized by the manufacturer.   Normal maintenance items
requiring routine replacement are not warranted. Unauthorized service voids the warranty and any resulting
charge or subsequent claim will not be paid. Products repaired or replaced under warranty shall be warranted
for the unexpired portion of the warranty applying to the original product. The foregoing is the exclusive
remedy of any buyer of the manufacturer’s product. The maximum damages liability of the manufacturer is the
original purchase price of the product or part.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IN LIEU OF ALL OTHER WARRANTIES, WHETHER WRITTEN, ORAL, OR
STATUTORY, AND IS EXPRESSED IN LIEU OF THE IMPLIED WARRANTY OF MERCHANTABILITY AND THE IMPLIED WAR-
RANTY OF FITNESS FOR A PARTICULAR PURPOSE. THE MANUFACTURER SHALL NOT BE LIABLE FOR LOSS OR DAMAGE
BY REASON OF STRICT LIABILITY IN TORT OR ITS NEGLIGENCE IN WHATEVER MANNER INCLUDING DESIGN, MANUFAC-
TURE OR INSPECTION OF THE EQUIPMENT OR ITS FAILURE TO DISCOVER, REPORT, REPAIR, OR MODIFY LATENT
DEFECTS INHERENT THEREIN. THE MANUFACTURER, HIS REPRESENTATIVE OR DISTRIBUTOR SHALL NOT BE LIABLE
FOR LOSS OF USE OF THE PRODUCT OR OTHER INCIDENTAL OR CONSEQUENTIAL COSTS, EXPENSES, OR DAMAGES
INCURRED BY THE BUYER, WHETHER ARISING FROM BREACH OF WARRANTY, NEGLIGENCE OR STRICT LIABILITY IN
TORT.

The manufacturer does not warrant any product, part, material, component, or accessory

manufactured by others and sold or supplied in connection with the sale of manufacturer’s products.

AUTHORIZATION FROM THE SERVICE DEPARTMENT IS NECESSARY BEFORE MATERIAL IS

RETURNED TO THE FACTORY OR IN-WARRANTY REPAIRS ARE MADE.
