The liability of tekmar under this warranty is lim-

Purchaser is authorized to pass through to its customers. Under 
the Limited Warranty, each tekmar Product is warranted against 
defects in workmanship and materials if the Product is installed and 
used in compliance with tekmar’s instructions, ordinary wear and 
tear excepted. The pass-through warranty period is for a period of 
twenty-four (24) months from the production date if the Product is 
not installed during that period, or twelve (12) months from the docu-
mented date of installation if installed within twenty-four (24) months 
from the production date.

The liability of tekmar under the Limited Warranty shall be limited to, at

to repair defects in materials and/or workmanship of the defective prod-
uct; or to the exchange of the defective product for a warranty replace-
ment product; or to the granting of credit limited to the original cost of the 
defective product, and such repair, exchange or credit shall be the sole 
remedy available from tekmar, and, without limiting the foregoing in any 
way,  tekmar  is  not  responsible,  in  contract,  tort  or  strict  product  liabil-
ity, for any other losses, costs, expenses, inconveniences, or damages, 
whether direct, indirect, special, secondary, incidental or consequential, 
arising from ownership or use of the product, or from defects in work-
manship or materials, including any liability for fundamental breach of 
contract.

The pass-through Limited Warranty applies only to those defective Prod-
ucts  returned  to  tekmar  during  the  warranty  period.  This  Limited  War-
ranty does not cover the cost of the parts or labor to remove or transport 
the defective Product, or to reinstall the repaired or replacement Product, 
all such costs and expenses being subject to Purchaser’s agreement and 
warranty with its customers.

to its customers which are different from or in excess of the tekmar Lim-
ited Warranty are the Purchaser’s sole responsibility and obligation. Pur-
chaser shall indemnify and hold tekmar harmless from and against any 
and all claims, liabilities and damages of any kind or nature which arise 
out of or are related to any such representations or warranties by Pur-
chaser to its customers.

The pass-through Limited Warranty does not apply if the returned Prod-
uct has been damaged by negligence by persons other than tekmar, 
accident, fire, Act of God, abuse or misuse; or has been damaged by 
modifications, alterations or attachments made subsequent to purchase 
which have not been authorized by tekmar; or if the Product was not 
installed in compliance with tekmar’s instructions and/or the local codes 
and ordinances; or if due to defective installation of the Product; or if the 
Product was not used in compliance with tekmar’s instructions.
