• Knowing the exact location of these compo-
nents makes subsequent troubleshooting and
repair of faulty elements easier.
Please the following:
• Observe all guidelines - see section 1.2 .
• Observe correct C-C distance (heating cables
only) - see section 2.1.
• Observe required installation depth and
possible mechanical protection of cold leads
according to local regulations.
• When installing more than one element, never
wire elements in series but route all cold leads
in parallel to the connection box.
• Two or more elements may be installed in
the same room but a single element is not
to be installed across two or more rooms.
• All heating elements in the same room must
have the same heat density (W/m2) unless
they are connected to separate floor sensors
and thermostats.
• For single conductor cables, both cold leads
must be connected to the connection box.

Preparing the installation area
• Remove all traces of old installations, if appli-
cable.
• Ensure that the installation surface is even,
stable, smooth, dry and clean.
• If necessary, fill out gaps around pipes,
drains and walls.
• There must be no sharp edges, dirt or foreign
objects.

Installing elements
It is not recommended to install elements at temper-
atures 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
If ohmic resistance and insulation resistance are not
as labelled, the element must be replaced.
