in workmanship and materials when the product is installed and used in compliance with tekmar's
instructions. This limited warranty covers the cost of parts and labour provided by tekmar to correct
defects in materials and/or workmanship. Returned products that are fully operational are not
considered a warranty case. tekmar also does not cover parts or labour to remove, transport or
reinstall a defective product. tekmar will not be liable for any damage other than repair or
replacement of the defective part or parts and such repair or replacement shall be deemed to be the
sole remedy from tekmar. This warranty shall not apply to any defects caused or repairs required
as a result of unreasonable or negligent use, neglect, accident, improper installation, or unauthorised
repair or alterations. In case of defect, malfunction or failure to conform to warranty, tekmar will, for
a warranty period of 24 months from the date of invoice to the original purchaser or 12 months from
the date of installation of the product, whichever occurs first, repair, exchange or give credit for the
defective product. Any express or implied warranty which the purchaser may have, including
merchantability and fitness for a particular purpose, shall not extend beyond 24 months from the date
of invoice or 12 months from the date of installation of the product, whichever occurs first.
Replacements: tekmar can send replacement products if requested. All replacements are invoiced.
Any possible credit for the replacement will only be issued once the replaced product has been
returned to tekmar.
Product Return Procedure: Products that are believed to have failed must be returned to tekmar
Control Systems Ltd. 4611-23rd Street, Vernon B.C. Canada V1T 4K7 when agreed to by tekmar. The
installer or other qualified service person must, at the owner's expense, determine which component
has failed. The product must be returned complete with all of its components (sensors, base, etc.).
Products must be returned together with the proof of purchase to the original purchaser who then returns
the product to tekmar after receiving a Return Goods Authorisation (RGA) number from tekmar.
Please include the following information with the product: The full address of the original purchaser,
the RGA number and a description of the problem.

returned for repair". For shipping purposes the product can be valued at one half list price.

product to the original purchaser for a testing cost of $30.00 plus postage.
3)
If returned during the warranty period and the product is not damaged and is fully operational,
tekmar can take back the product for a return charge of 40% of the product's net value. This
request has to be specified otherwise the product will be returned with a testing cost of $30.00
plus postage.

the product. Repair and postage costs will be invoiced. tekmar's repair costs are calculated

estimate will be sent to the original purchaser.
