ALUMINIUM HEATING MATS FOR USE UNDER FLOATING FLOORS
GENERAL CONDITIONS

Heating mats may be operated only as a part of the structure of a building, and indoors. The
construction of the mat enables its use also in damp environments. In the case of installation in a
damp environment, always connect the connector on the mat to a protective conductor.

The mats are intended only for installation under floating laminated floors which are intended for use
with floor heating by the manufacturer.

It is prohibited to install the mats under floor tiling, marble, natural stone ,… The mats must not be
installed into construction adhesives or screed materials, and any possibility of the mat coming into
contact with such materials must be avoided
– there is a danger that the materials will react with the
Al layer of the mat.

Instal
l the side marked “This side up” facing the floor covering.

In places where the mat is not installed in the ground plan, it is necessary to even out the surface
using a levelling layer.

Do not use cellulose insulation.

Do not install insulation material between the heating mat and the floor covering; do not use
coverings which contain an impact noise insulation layer.

Make sure that no sharp edges of the floor covering system come into contact with the heating foil.

The mat can be adapted only as shown in pictures 1-3 - it must not be shortened under any
circumstances. Only cold connection ends can be shortened as needed. The minimum distance of
the mat from the walls and fixed furniture or equipment is 50mm. If the heating cable or the supply
lead is damaged, it has to be replaced or repaired by the manufacturer, a service technician from
the manufacturer or a similarly qualified person in order to prevent the occurrence of a dangerous
situation. Do not install the cables using nails or screws! The individual strips of the heating foil
mustn´t be in contact with, cross or overlap one another. Safeguard the individual strips of the mat
against sliding by gluing them to the base; we recommend an aluminium adhesive tape (not part of
the product).

After adaptation of the mat, the heating conductor must always be taped over with a connecting
tape which simultaneously creates a conductive connection with the aluminium foil.

It is prohibited to install floor anchoring elements, screws, wall plugs, etc. in places where the
heating mat is installed.

During installation, please adhere to the requirement that the diameter of any bend in the cable
must be at least eight times the size of the cable’s diameter.

The heating mat must be powered via a residual current device with a nominal residual current of
I∆n≤30A. We recommend that each heating complex/circuit is fitted with an independent residual
current device.

For safety reasons, it is prohibited to install heating mats in walls.
