Installation Instructions

The surface-heating elements have been tested to VDE Standards in

accordance with DIN EN60335-1, DIN EN60335-2-96 and DIN EN50366.

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 0,5 square meter

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 - Part 753 and VDE 0100 - 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.

Warning notice

Warning notice according to A2 EN 60335-1:2006: This surface-heating element is not intended for being

used by persons (including children) with limited, physical, sensory or mental abilities or in absence of

experience and/or in absence of knowledge, unless they are supervised by a person which is responsible

for their security or received instructions from this person mentioned above, how this surface-heating

element is to be used.

Children should be supervised, in order to assure, that they do not play with the device.

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 surface-heating element or the like. The surface-

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 surface-heating element and the installer must enter the lay-out details of each surface-

heating 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 surface-heating element should have the least

possible resistance to the conduction of heat. Care must be taken to ensure that the surface-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 surface-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 surface-heating elements from the connection socket or directly to

the thermostat. Several different surface-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.

Control Units for the electrical surface-heating elements For the following thermostats (type digital OCC2-1991-xx and type standard OTN-1991-xx, manufactured by OJ Electronics A/S, DK 6400 Sønderborg) our surface-heating elements have been tested according to the VDE Standards DIN EN 60335-2-96. These correspond to the DIN Standards EN 60730-1 and EN 60730-29.
