Check cable integrity when to test?

1) When receiving the cable;

2) After laying the cable in the membrane or suboor with our plastic cable guides and

before covering the the cable with cement;

3) After covering the cable with cement and before laying the oor covering;

4) After the installation of the oor covering and before connecting the heating cable to the

thermostat. Enter all test results on the warranty log.

Before removing the plastic that covers the cable on the spool, the cable insulation and

resistance should be veried and compared to the factory values to ensure the cable is

intact. Factory test data is on the grey tag at the end of the cold lead black cable. Results

should be similar to the factory result. Please refer to it. If it is more than +/-10% difference,

call WarmAll.

You must perform the lnsulation Resistance Test, the Resistance Test, and the Sensor

Resistance Test (the oor sensors, are in the thermostat & cable box) during the installation

process.

Use an appropriate multimeter to measure the resistance between the 2 conductor leads. If

an automatic multimeter is used the reading will be taken instantly. If the multimeter is not

automatic, set it to 200 Ω for a cable under 200 Ω or at the higher value for a cable over

200 Ω. Write the result on the Test Log Sheet to register your Warranty. Please check that

your measuring instrument is set properly calibrated.

Heating Cable lnsulation Resistance Test

This test ensures that the insulating jackets of the cable are not damaged. A low value

indicates the cable has been damaged and must be replaced. Use a multimeter or a

megohmmeter.

Connect the ground wire to the

black lead of the tester and both

load wires (heating cable) to the red

lead of the multimeter or megger.

Make sure the meter reads “OPEN”

or “OL” or ‘I’. If you get a different

reading, contact WarmAll at

1-855-396-5600.

Record these readings on the test

log sheet to register your warranty.

For the Full Limited Warranty to be valid you must perform the insulation resistance test

using a megohmmeter (megger). ln a two-step method, perform the above test at 500 volts

DC and then at 1000 volts DC. Please record the readings on the Test Log Sheet.
