Installation Guide

INSCT0816
6
Plan the location of the thermal sensor between two cable runs, at a distance of at least 24 inches (60 cm) from the wall or centered between walls (see
FIGURE 14). The sensor should be installed in an area where temperature reects the overall temperature of the oor. Thus, it should not be located in
areas likely to alter the temperature measurement, like an entrance door, an external heat source, under pieces of furniture or an area exposed to the sun.
Make sure the sensor wire does not overlap the heating cable.
REQUIRED TESTS AND WARRANTY CARD
INTRODUCTION – IMPORTANCE OF THE REQUIRED TESTS
Each cable is subjected to factory quality control. However, several operations, starting from the moment you unpack the cable to the rst start up, may
compromise the cable integrity. In order to ensure that the cable quality remains unchanged throughout the installation process, ohms readings must be
conducted while the cable is still on the spool and during two specic subsequent steps. If the tests are not performed and duly noted on the warranty card,
the warranty will be void.
Measurements must be recorded in the warranty card and be compared to initial measurements taken when the cable was on the spool in order to enable
you to detect changes, if any, related to the electrical property of the cable.
Since it could be very expensive to repair the cable once it is embedded in concrete, it is crucial to detect any breaks that may occur during the installation
process as soon as possible. Therefore it is important to conduct the required ohms reading when prescribed. If the cable gets damaged during installation,
you must call a qualied repair technician referred by Stelpro. To do so, call Stelpro Customer Service or consult the website (www.stelpro.com). Any
installation-related cable damages are not covered by the warranty.
CHRONOLOGICAL ORDER OF THE REQUIRED TESTS
FIRST TEST SERIES (TESTS 1, 2, & 3) - while the cable is still on the spool
SECOND TEST SERIES (TESTS 1, 2 & 3) - after the installation of the cable on the suboor, preceding the pouring of the concrete
THIRD TEST SERIES (TESTS 1, 2 & 3) - once the concrete has completely dried
TESTS 1, 2 & 3
TEST # 1 : CONDUCTOR RESISTANCE TEST
This test requires the use of an ohmmeter (multimeter)
In order to perform the resistance test, you must set your multimeter for a resistance
measurement and take an ohms reading between the two power leads. If the ohms
reading taken on the two power leads varies signicantly (10% or more) from the value
printed on the spool, it either means that the cable has been damaged, or that the
measuring instrument is not set properly, or that it is simply out of calibration. The ohms
measurement must be recorded in your warranty card.
TEST 1 - CONNECTIONS
USING A MANUAL RANGE MUTLIMETER
The selected range must correspond to the
multimeter’s lowest ohms range that encompasses
the cable nominal ohms value.
In the example (see FIGURE 4), a 200 ohms range
has been selected to measure a 28 ohms cable.
