The heating cable consists of two parallel heating wires with an additional common PE conductor and an outer sheath. At one end of the heating mat, the two heating wires are connected to each other, at the other end a common cold tail with PE conductor and color coded (blue and black) single conductors is located. The connection on one side only enables particularly easy installation. All electrical connections must be carried out by a qualified, licensed electrician. Important installation considerations

The installation must comply with all relevant VDE regulations, in particular DIN VDE 0100, Part 520 A3.

The scope of delivery and accessories must be checked for agreement with the planned project.

The sub-floor surface must be stable and free from vibrations.

Thermal insulation under the sub-floor surface is absolutely necessary in cases where the mats are installed over soil or unheated spaces.

When installing the heating mats make sure that selfadhesive mats are placed with the synthetic mesh backing facing down. Non-self-adhesive heating mats should be installed with the synthetic mesh backing facing up.

The tile adhesive, flexible mortar or levelling compound used must be suitable for the underfloor heating system. Special accessories are available to extend the cold tail, if required. HM SF Heating mat construction The heating wire is attached in a loop pattern to a synthetic mesh thus forming a heating mat with predetermined dimensions. At either end of the heating mat, or the heating wire, a colour coded cold tail (blue and black) is provided for connection to the power supply. Heating wire and cold tail are provided with an additional protective braiding for connection to the PE conductor. Special accessories are available to extend the cold tail, if required. Preparation of the installation area

Heating mats, heating cable and cable splices must be completely embedded in the mortar.

Do not bend heating cables at right angles.

Heating cables must not touch or cross each other: Minimum distance: 6 cm.

Prior to the installation of the heating mat, the installation area must be carefully inspected. Any cracks that may be present have to be repaired using epoxy resin. Make sure that the floor surface is free of any sharp objects that could possibly pierce the heating mat. An edge insulation strip (plastic foam thickness approx. 8 mm) is to be fixed along all walls, support columns, etc. Do not run heating cables over expansion joints or apparent joints. Installation instructions

Do not cut or shorten the heating cable nor connect it directly to the power supply.

At installation, a Residual Current Device is to be provided as protection against indirect contact (sensitivity ≤ 30 mA).

All relevant VDE and TAB regulations must be complied with.

The lowest installation temperature of the heating mat is 5 °C, the maximum permissible surface temperature is 80 °C.

If more than one heating mat is to be connected, the maximum permissible load is 16 A. Self-adhesive heating mats have to be laid on the floor with the synthetic mesh backing facing down, non-self-adhesive heating mats have to be laid with the synthetic mesh backing facing up, in accordance with the installation plan. The shape indicated on the plan can be achieved by cutting the synthetic mesh backing at the predetermined turning points. Heating mats should match the desired heated floor area as closely as possible. Caution! Do not damage the heating wire. Bend the heating mat at the cutting point and lay the next mat length parallel to the first length. A minimum distance of 6 cm between the heating wires must be maintained! 6 cm Field of Application This ultra-thin heating mat is used for floor warming and is installed directly under the floor covering. It is suitable both as supplemental heating system or as the primary heating source (heat requirement to be taken into account!). As it is only approx. 3-4 mm thick, this heating mat is mostly used for the remodeling of bathrooms, showers, kitchens, etc. Maximum thickness of floor covering Tiles Parquet Carpeting Laminate PVC 30 mm 16 mm 10 mm 8 mm 10 mm The connecting ends (cold tails) are routed along the outside of the heating mats to the electrical connection box. The heating mats must not cross each other! During installation, avoid walking on the heating mats, if possible.

Prior to embedding the heating mat in mortar, conduct an insulation resistance test, i.e. measure the resistance of the heating mat and record the value in the test/warranty chart. The products suitable for laying the heating mats are available from different manufacturers. Be sure to follow the manufacturer's directions for the mortar product. Installation The installation of the electric heating system may only be carried out by a qualified, licensed electrician. The heating system is to be provided with an all-pole disconnect device with a contact gap per pole of at least 3 mm. A Residual Current Device is to be provided as protection against indirect contact (sensitivity ≤ 30 mA). The floor sensing probe of the thermostatic controller must be placed in a conduit sealed at one end and installed directly into the heated floor area. Position floor sensor at a point midway between heating cable runs. Where heating mat cold tails transition from the floor to the wall up to the connection box they must be protected in a conduit. The cold tail ends of each heating mat are connected to the 230V~ mains voltage via the control device. The earthing braid of the heating cable must be connected to the earth conductor. See also the Chapter "Connection of the cold tails". Installation on cement screed

Prime sub-floor and allow to dry. ● Fix self-adhesive heating mat to sub-floor surface and cover with flexible mortar or levelling compound. As an alternative, first apply flexible mortar and press the heating mat into the mortar with the heating mat mesh backing facing down. ● If non-self-adhesive heating mats are used, apply flexible mortar and press the heating mat into the mortar bed with the plastic mesh backing facing up. Allow mortar and levelling compound, if any, to dry. Even out any irregularities using levelling compound and allow to dry. Installation on ceramic floors, artificial or natural stone tiles

Existing floor coverings must adhere properly. Remove any contamination such as wax or grease using household cleaners or degreasing agents. Proceed further as described under "Installation on cement screed" (see above).
