TESTS
Even though each mat and cable is subject to factory quality control, testing is essential to ensure that your product remains fully functional
throughout the installation process. Repairing a cable once it is covered with cement, mortar and a nishing coating can be very expensive.
Three electrical tests must be performed at different stages of the installation process, and their results must be recorded in the warranty booklet.
Comparing the results of the different tests will indicate if any changes have occurred during installation.
As all measuring instruments are different, we recommend that you consult resistance measurement section of your instruments’ user guide
before proceeding.
If the cable is damaged during installation, contact a qualied °STELPRO-approved repair technician. Call °STELPRO customer service or visit
www.stelpro.com for more details. Note that damage caused to the cable during installation is not covered under the warranty.
WHEN SHOULD TESTS BE DONE?
Three tests must be performed:
• As soon as the cable is removed from the box and while it is still on the spool with the plastic seal covering the splice. As soon as the seal
is broken the warranty will be void since the cable may have been unspooled and installed. If the tests indicate that the cable is defective
before being unspooled (with the seal intact), the °STELPRO warranty will apply.
