LATICRETE STRATA_HEAT 0802-0017-2, Installation Manual

14

Each and every STRATA_HEAT™ Wire loose heating cable is subjected to careful testing before it is shipped from the factory. 

However, damage does sometimes occur in storage or transit, and sometimes during 

installation. We strongly recommend 

you test your heaters:

  After unpacking them but before you install them,  

 and
   After you have installed them but before you install the floor 

covering (i.e. while the cables are still exposed),  

and

  After installation of the final floor covering.

Complete a simple visual inspection of the heating cable to make sure there is no visible damage.
A simple electrical inspection can be done with a digital ohmmeter to ensure the ohms resistance is what it should be. The ohm 

resistance should be measured between the two conductors without touching the yellow-green wire, which is the ground connection. 
Checking for resistance between the two conductor wires ensures there is no break in the cold lead conductor and the heat resistance 

wire. It does not assure you that there is no electrical short in the circuit. 
Place one probe on the black wire. Place the other probe on the yellow (red wire for 240V).
Resistance can vary significantly depending on the ambient temperature and an allowance of +/- 5% from the norm is 

acceptable.

Ensure cable is fully insulated:

Test across the yellow-green wire (ground). Place the other probe on the yellow (red wire for 240V ).
Confirm the reading is infinity (open circuit).
Repeat these steps to check the reading between the yellow-green wire (ground) and the black wire.
There should be no continuity between these wires and the ohms reading should be infinity (not zero). If your meter shows a number of 

ohms between these wires, your heating cable has an electrical short. Take note of the resistance and contact LATICRETE.
In order to conduct a more thorough test for insulation verification, LATICRETE recommends the use of a megohmeter. Connect the 

instrument’s black cable to the system’s ground and the red to the either one of the heating cable leads.   
Note that depending on your meter model, you may read “kilo-Ohms” probably due to your fingers touching the probes (it’s your 

body’s conductivity). If the readings are not satisfactory, do not commence installation contact LATICRETE for further advice.
