Elements must always be installed according to 
local building regulations and wiring rules as 
well as the guidelines in this installation manual

•  Any other installation may hamper element 

functionality or constitute a safety risk, and 
will void the warranty.

•  Make sure that elements, cold leads, connec-

tion boxes, and other electrical components do 
not come into contact with chemicals or flam-
mable materials during or after installation.

Elements must always be connected by an au-
thorised electrician using a fixed connection.

•  De-energize all power circuits before installa-

tion and service.

•  The connection to the power source must not 

be directly accessible to the end user.

•  Each heating cable screen must be earthed in 

accordance with local electricity regulations and 
connected to a residual current device (RCD).

•  Recommended RCD trip rating is 30 mA, but 

may be up to 300 mA where capacitive leak-
age may lead to nuisance tripping.

•  Heating elements must be connected via a 

switch providing all pole disconnection.

•  The element must be equipped with a cor-

rectly sized fuse or circuit breaker, e.g. 10/13 A 
for a 1.5 mm

2

 cold lead and 16/20 A for a 

2.5 mm

2

 cold lead.

Pipe Tracing

•  Sensor
•  Heating Cable
•  Insulation
•  Fitting
•  Valve

The presence of a heating element must

•  be made evident by affixing caution signs or 

markings at the power connection fittings 
and/or frequently along the circuit line where 
clearly visible.

•  be stated in any electrical documentation 

following installation.

Never exceed the maximum heat density (W/m)  
for the actual application.

1.3 

Handling

•  If the heating cable is delivered on a cable 

drum you should use a reliable holder for the 
drum when unrolling the cable.

•  Pull the heating cable straight of the drum. 

•  Avoid pulling violently, breaking or squeezing 

the heating cable.

•  Do not place the heating cable over sharp 

objects or edges.
