Installation Guide

Each heating cable is subject to factory quality control. However, damage to the cables may happen after the product leaves the factory. In order to ensure
that the cable quality remains unchanged throughout the installation process and for warranty purposes, tests must be conducted while the cable is still on the
spool and during two specific subsequent steps. Measurements must be recorded in the table below and compared to initial measurements taken when the
cable was on the spool in order to enable you to detect any changes related to the electrical property of the cable. Any installation-related cable damages are
not covered by the warranty. See page 21 in this DITRA-HEAT Installation Handbook for complete heating cable testing instructions.
The DITRA-HEAT system has warranty coverage up to a period of fifteen (15) years. In order to receive warranty coverage,
the owner must complete and submit the warranty registration card and completed heating cable tests log to Schluter Systems online at
https://www.schluter.com/schluter-us/en-US/registerwarranty or via mail at the address provided heaeafter within fourteen (14) day of installation. It is an
installation requirement that the heating cable tests log be completed by the installer at the time of installation with a copy submitted to Schluter Systems; it is
recommended that the owner retain the original logs. The heating cable tests log must include results for the following tests: “Test 1: Conductor Resistance,”
“Test 2: Conductor and Ground Braid Continuity,” “Test 3: Insulation Resistance,” and “Test 4: Thermostat Floor Temperature Sensors Test.” Failure to
conduct these tests and submit the heating cable tests log will reduce or may void coverage under this Limited Warranty.
In the event the heating cable tests log only includes the results for “Test 1: Conductor Resistance,” “Test 2: Conductor and Ground Braid Continuity,”
and “Test 4: Thermostat Floor Temperature Sensors Test,” but does not include results for “Test 3: Insulation Resistance,” the applicable warranty term
shall be ten (10) years from the date of purchase. If the heating cable tests log does not include test results for “Test 1: Conductor Resistance,” “Test 2:
Conductor and Ground Braid Continuity,” and “Test 4: Thermostat Floor Temperature Sensors Test,” such installation does not qualify for coverage under
this Limited Warranty.
Completion of warranty registration qualifies customers for the system warranty, in which Schluter
®
-Systems shall a) reinstall or replace the failed portion
of the floor covering assembly or b) pay an amount not to exceed the original square foot cost of the installation of the floor covering assembly verified to
be defective.
The owner must retain a copy of this heating cable tests log for warranty purposes.
