Installation Instructions
The surface-heating elements have been tested to
VDE Standards in
accordance with DIN EN60335-1 and DIN EN60335-2-96.
These instructions must be read carefully before commencing the installation procedure. Whenever work is
being undertaken on this heating equipment the relevant VDE-Regulations must be readily available and
handed directly to the installer. These instructions relate to the Surface-heating Elements 1 square metre to
10 square meters. The manufacturer guarantees the product for a period of 10 years. This guarantee does
not include any preparatory work or replacement of surface covering material. Installation must be carried
out by a qualified person and be made strictly in accordance with the appropriate Standards and
Regulations, such as, for example, VDE 0700 - Teil(Part) 753 and VDE 0100 - Teil(Part) 701. Please pay
careful attention to the information given on the Guarantee Card. The specified entries (measured values
made on the completed installation) must be recorded on that Guarantee Card. The manufacturer will not
accept responsibility for any faults which can be attributed to measurements which either have not been
made and recorded at all or which have been made incorrectly.

Precautionary Measures
Care must be taken to ensure that during the course of the installation procedure no damage is caused by,
for example, falling objects, sharp objects, walking on the heating element or the like. The heating elements
are to be powered by a circuit with a fault current breaker (F-1 Protection Switch) with a release current of
30 mA. It is necessary to mount a warning notice in the close proximity of the distribution system which fully
describes the lay-out of the heating unit. One of these plaques (about 105 x 148 mm) is required for each
heating element and the installer must enter the lay-out details of each element on the relevant plaque (a
sketch will suffice). The heating cable must not be shortened or crossed over itself. The flooring material
covering the heating element should have the least possible resistance to the conduction of heat. Care must
be taken to ensure that the heating element is not trodden upon while the floor material is being laid. It is
also necessary to avoid laying the material over screed expansion joints. Normal practice involves using a
control thermostat with a floor-sensor, with the sensor inserted in an empty pipe. Please note that a
defective sensor will not be replaced unless it was protected in this way. The sensor should be located close
to the floor surface and between two lengths of heating cable. In the same way, the cold conductor
(connecting cable) is also to be laid inside a separate empty pipe. For safety reasons a switching device
should be used which ensures an all-pole disconnection of this permanently fixed equipment. This can be,
for example, a 2-pole F1-Protective Switch (with a 3 mm gap).

Laying Procedure
The purpose of the heating elements is to provide direct heating and to achieve control of floor surface
temperatures. They must not be used for insertion in walls or ceilings. The individual loops of heating cable
should run parallel to one another over the floor area and they should be separated by a minimum distance
of 5 cm. The cold conductors (connection cables) must not cross over themselves. They are to run
alongside and parallel to the heating elements from the connection socket or directly to the thermostat.
Several different heating elements can be connected in parallel to one thermostat (in a similar manner to the
connection of several light bulbs in a lighting fixture). In this situation we recommend the use of a
connection socket.

The heating elements are to be embedded in a flat, single plane within the adhesive- or filling mass. Ensure
that no air bubbles are trapped and that the glass-fibre gauze fabric lays completely flat on the floor surface
with no folds. In order to avoid heat or energy losses into the sub-floor and thereby to ensure optimum
heating of the upper floor surface the existing insulating material between the sub-floor surface and the
heating element must correspond to the latest state of the technology. Finally there must be a minimum
distance of 30 mm between the electrical elements and any conductive system, e.g. water-pipes.
