Planning the Installation
Draw a sketch of the installation which shows
• element layout
• cold leads and connections
• junction box/cable well (if applicable)
• sensor
• connection box
• thermostat
Save the sketch
• Knowing the exact location of these compo-
nents makes subsequent troubleshooting
and repair of faulty elements easier.
Bear in mind the following:
• Observe correct C-C distance (heating cables
only) - see section 2.2.
• Observe required installation depth and pos-
sible mechanical protection of cold leads.
• When installing more than one element,
never wire elements in series but route all
cold leads in parallel to the connection box.
2.6
Preparing the Installation Area
• Remove all traces of old installations, if ap-
plicable.
• Ensure that the installation surface is even,
stable, smooth, dry and clean.
• If necessary, fill out gaps around pipes,
drains, or walls or apply foil covering
• There must be no sharp edges, leaves, dirt or
foreign objects.

Installing Heating Elements
It is not recommended to install elements at tem-
peratures below -5 °C.
At low temperatures, heating cables can become
rigid. After rolling out the element, briefly connect
it to the mains supply to soften the cable before
fastening.
Measuring Resistance
Measure, verify and record element resistance dur-
ing installation.
• After unpacking
• After fastening the elements
• After the installation in finalized
Also measure if there is connection between the
two conductors or from the conductor to the metal
sheath.
