The installation of an electric heating cable must be installed by a professional electrician confirmed heat tracing.
It is important to give importance to site preparation and should be avoided :
• The mechanical stresses on the cable (traction, torsion, small radius of curvature)
• To bend, twist and crush the heating cable
• To walk or ride on the cable
• To store the cables in a damp environment
• The sharp edges that could damage the sheath
• The infiltration of moisture or liquid to the cable ends
• Implementations or installation under a temperature below -20 ° C.
"A self-regulated or self limiting heating cable must be handled during preparation and installation as carefully as an optical fiber : this is an electronic component."
The endings kit will prevent the infiltration of moisture. It is imperative to use the endings kit.
It is composed of shrinkable sheaths and other accessories for the electrical connection on one side and to seal the cable on the other side.
1. Ending to seal one side for B300, B800 and M800 :
2. Ending on the electrical connection side for B300, B800 et M800 :
1. Ending on one side :
2. Ending on the electrical connection side for B100 et M100 :

Metal and plastic pipe
On polymer piping (low thermal conductivity) of type PVC, modified PVC, PA, thermoplastic elastomer, rubber ... It is imperative to put an aluminum tape on the pipe to facilitate heat transfer.
Implementation on metal pipe
Always remember to clean the surface of the pipe to contact the heating element on the pipeline and for membership of the adhesive to the pipe.
Implementing rules on a pipe
Make sure of a good contact between the heating cable and the pipe
Use fiberglass and aluminium adhesive to secure and ensure the heat transfer on the pipe
Put heating cables in straight or spiral by avoiding overlap
Position the cable at 4am or 4am and 8am. Avoid at 6am or 12am !
Examples of tracing for equipment and piping
Bypasses are lower diameter than the main pipe. We should not undertake round trip cabling on a great length bypass which would have for consequence an overheating.
A small length bypass : 1,5m maximum.
Large length bypass : more than 1,5m.
For the great length bypasses stop the circuit and install a junction box.
Power supply and electrical protection must comply with electrical codes.
Ensure the presence of a differential 30mA on the electricity grid.
Having a curve D circuit breaker on the electrical circuit.
Verify the water tightness of the extremities.
Check the insulation resistance value (value greater than 100MΩ / 2500V) between the cable conductors and the grounding of the heating cable.
Having a thermostat for each cable length.
Verify the proper functioning of the entire electrical tracing before setting up the insulation.
We recommend you to read this document carefully before installing your heating cables. This documentation covers the installation and safety instructions.
The installation must be performed by a professional electrician confirmed heat tracing.
