User manual DIMPLEX HMTS 10-2010

[. . . ] 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. Heating mats, heating cable and cable splices must be completely embedded in the mortar. do not bend heating cables at right angles. [. . . ] 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!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!3-4 mm thick, this heating mat is mostly used for the remodeling of bathrooms, showers, kitchens, etc. 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. 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. 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. 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. [. . . ] Terminal of shield of cold tail for line protection and residual current monitoring. In the case of textile or PVC floor covering, the mat must be covered with a layer of at least 10 mm of levelling compound as a mechanical protection measure. The following documents have to be turned over to the operator of the system: · Installation instructions with completed test record, · Revision plan showing the location of heating mats, temperature sensor and furniture arrangement as well as splices of heating wires and cold tails. Several thermostatic controllers suitable both for surface and flush mounting are available to regulate the floor and/or room temperature. [. . . ]
