WARNING: NEVER CUT OR SHORTEN THE HEATING CABLE
Start by placing the heating cable such that the
connection point and the temperature sensor are
in their intended positions and bring the power
cable to the thermostat or connection box. Avoid
walking on the heating cable. If this is not possible,
use shoes with soft soles.

Use BVF fixing strips or mesh for fixing the cable
on the floor. The strips or mesh shall be glued or
screwed to the subfloor. Unroll the heating cable
carefully and lay it according to the system design.
i Important
It is highly recommended taking photographs of
the installed system before installing the flooring.
7. Measure the resistance (second time)
Please refer to Step 5.
8. Fixing the heating cable
Fix the cable on the subfloor with the cable distance specified in figure 31 to achieve the desired capacities
9. Embed the heating cable
In the case of tiles, proceed with the installation
of the tiles by covering the heating cables with
a layer of thin-set cement as directed by the tile
manufacturer. Ensure that the thin-set mortar
covers the entire height of the heating cable as the
tiles are installed. In the case of a wood, engineered
or laminate floor covering, it is recommended
that the flooring manufacturer be contacted. For
wooden floors, a minimum of 5cm of self-leveling
cement over the heating cable is recommended.
Ensure that all moisture in the self-leveling cement
has been fully eliminated in accordance with the
drying times recommended by the manufacturer.
i Important
The system must not be turned on until the thin-set cement has fully dried. A minimum of two weeks is
recommended.

Please refer to Step 5.
11. Install the tile
Tile and grout the floor using best industry practices and in accordance with instructions provided by the
manufacturer of the tile.
12. Connect power supply and thermostat
The connection of the power supply and the thermostat must be done by a qualified electrician. The
electrician should connect the floor sensor to the thermostat, take the final resistance reading and record
it on the warranty card, see Step 13.
