tekmar 256 Boiler Control - Manual (Page 20)

Limited Warranty The liability of tekmar under this warranty is limited. The
Purchaser, by taking receipt of any tekmar product (“Product”), acknowl-
edges the terms of the Limited Warranty in effect at the time of such Prod-
uct sale and acknowledges that it has read and understands same.
The tekmar Limited Warranty to the Purchaser on the Products sold hereun-
der is a manufacturer’s pass-through warranty which the Purchaser is autho-
rized 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 documented
date of installation if installed within twenty-four (24) months from the produc-
tion date.
The liability of tekmar under the Limited Warranty shall be limited to, at tekmar’s
sole discretion: the cost of parts and labor provided by tekmar to repair defects
in materials and / or workmanship of the defective product; or to the exchange
of the defective product for a warranty replacement 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 liability, for any other losses, costs, expenses, inconveniences, or
damages, whether direct, indirect, special, secondary, incidental or consequen-
tial, arising from ownership or use of the product, or from defects in workman-
ship or materials, including any liability for fundamental breach of contract.
The pass-through Limited Warranty applies only to those defective Products
returned to tekmar during the warranty period. This Limited Warranty 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.
Any representations or warranties about the Products made by Purchaser to its
customers which are different from or in excess of the tekmar Limited Warranty
are the Purchaser’s sole responsibility and obligation. Purchaser 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 Purchaser to its customers.
The pass-through Limited Warranty does not apply if the returned Product 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 instruc-
tions 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 instruc-
tions.
THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR
IMPLIED, WHICH THE GOVERNING LAW ALLOWS PARTIES TO CONTRAC-
TUALLY EXCLUDE, INCLUDING, WITHOUT LIMITATION, IMPLIED WARRAN-
TIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE,
DURABILITY OR DESCRIPTION OF THE PRODUCT, ITS NON-INFRINGE-
MENT OF ANY RELEVANT PATENTS OR TRADEMARKS, AND ITS COMPLI-
ANCE WITH OR NON-VIOLATION OF ANY APPLICABLE ENVIRONMENTAL,
HEALTH OR SAFETY LEGISLATION; THE TERM OF ANY OTHER WARRANTY
NOT HEREBY CONTRACTUALLY EXCLUDED IS LIMITED SUCH THAT IT
SHALL NOT EXTEND BEYOND TWENTY-FOUR (24) MONTHS FROM THE
PRODUCTION DATE, TO THE EXTENT THAT SUCH LIMITATION IS ALLOWED
BY THE GOVERNING LAW.
Product Warranty Return Procedure All Products that are believed to have
defects in workmanship or materials must be returned, together with a written
description of the defect, to the tekmar Representative assigned to the territory
in which such Product is located. If tekmar receives an inquiry from someone
other than a tekmar Representative, including an inquiry from Purchaser (if not
a tekmar Representative) or Purchaser’s customers, regarding a potential war-
ranty claim, tekmar’s sole obligation shall be to provide the address and other
contact information regarding the appropriate Representative.
The installer must ensure that this control and its wiring are isolated and/or shielded from strong sources of electromagnetic noise. Conversely,
this Class B digital apparatus complies with Part 15 of the FCC Rules and meets all requirements of the Canadian Interference-Causing Equip-
ment Regulations. However, if this control does cause harmful interference to radio or television reception, which is determined by turning the
control off and on, the user is encouraged to try to correct the interference by reorienting or relocating the receiving antenna, relocating the
receiver with respect to this control, and/or connecting the control to a different circuit from that to which the receiver is connected.
Cet appareil numérique de la classe B respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.
Caution The nonmetallic enclosure does not provide grounding between conduit connections. Use grounding type bushings and jumper
wires.
Attention Un boîtier nonmétallique n’assure pas la continuité électrique des conduits. Utiliser des manchons ou des fi ls de accord spécialement
conçus pour la mise á la terre.
