Installation – for qualified contractors
9.4 Laying out the heating mat
Material losses
!
Do not cut, squash or kink the heating conductor on
the heating mat.
You may shorten and extend the cold lead as long
as you do not change its cross-section.
Material losses
!
» Do not use nails or other metal objects to attach
the heating mat to the floor.
» Only stand on the heating mat if absolutely nec-
essary. Take any necessary protective meas-
ures to avoid mechanical damage (e.g. shoes
with rubber soles).
Material losses
!
» Do not install the heating mat through or be-
neath insulating material.
» The installed heating mat may not cross expan-
sion joints in the floor.
» Do not use penetrating fixing materials in the
vicinity of the heating mat, e.g. screws and rawl
plugs for door stoppers, WC fittings.
Observe the position of the heating mat specified in the
installation diagram for the subsequent steps.
» Lay out the heating mat in accordance with the in-
stallation diagram. The self-adhesive side must be
facing downwards.
» Cut the heating mat backing fabric with scissors at
the turning point. Make sure that you don't acciden-
tally damage the heating conductor with the scissors.
Material losses
!
The heating conductor bending radius must be at
least 18 mm. The smallest permissible bending radi-
us is six times the diameter of the heating conductor.
» Carefully bend the heating conductor at the cutting
point.
» Observe minimum distances (see chapter "Prepara-
tions / Safety clearances").
» Make sure that the temperature sensor lead does
not cross or touch the heating conductor and that the
temperature sensor is halfway between two heating
conductor loops.
» Make sure that heating mats do not overlap. Overlap-
ping heating mats may lead to malfunctions.
» Make sure that the fabric is laid out without any
creases.
» Press the heating mat firmly onto the floor.

9.5 Test measurement 2
After laying out the heating mat, check the total resistance
and insulation resistance of the heating mat to rule out the
possibility of damage to the heating mat.
Note
The warranty is not valid without proof of this meas-
urement.
» Measure the total resistance and insulation resist-
ance of the heating mats.
» Check whether the measured values are in the per-
missible measuring range (see chapter "Specifica-
tion / Data table").
» Enter the measured values on the warranty card.
» Replace the damaged heating mat if the measured
values deviate from the permissible range.
9.6 Laying the floor covering
Material losses
!
Only use tile adhesive and levelling compound
which are suitable for underfloor heating systems
and which can withstand constant temperatures of
at least 80 °C.
Material losses
!
When applying tile adhesive and levelling com-
pound, please observe the manufacturer's instruc-
tions concerning drying time and other manufactur-
er's information.
Note
You must wait at least 3 days, depending on the hu-
midity levels within the building, before starting to
lay the floor covering.
9.6.1 Tiles
» Select an appropriate tile adhesive or levelling com-
pound if applicable. Note that this must be able to
withstand constant temperatures of at least 80 °C.
» Seal the conduits so that tile adhesive cannot get
into the conduits whilst installing the heating mats.
