1 TThe Heating Mats Single-side power supply Double-side power supply AApplication The heating mats may be used as the basic heating system or they may supplement the existing system. The most often they are used in the places where due to the structural reasons, the assembly of the "simple" heating cables (considerable elevation of the floor's level) would be inconvenient. They may be assembled in practice everywhere since they are only 3 mm thick. The effect of the "warm floor" is achieved in a very short time. It is the quickest, the simplest and the most effective way of heating or reheating rooms or just chosen spots - with the minimal amount of labour. 1

2 Virtues Simple assembly Comfort of use Safety Low cost Maintenance the heating mats are stuck directly to the correctly prepared floor with the use of the tiles adhesive exceptionally simple and quick way of the heating system's assembly the whole service is limited to the adjustment of an appropriate temperature with the use of a controller the even temperature in the whole room low temperature of the heating surface (i.e. the floor) warm, dry floor in a short time absolutely unseen heating system the entire length of the cable is shielded and earthen or neutralised the joint the cable by a diverse power switch eliminates any danger exceptionally low cost of the system's assembly low operating costs - thanks to the easy adjustment of temperature the selected surfaces are heated only when necessary the problem does not exist

3 Characteristics The ELEKTRA heating mats are produced in the form of the finished sets that are prepared directly for the assembly. We can differentiate two types of heating mats, powered either on one or both sides. Single side powered mats, due to their construction, are easier to assemble and install. Double-side powered mats are thinner and during their installation it must be remembered to lead both cold tails into the power supply. The heating cable is attached to a plastic netting. The end of the heating cable is terminated with an originally attached 4-meter cold tail. There exists the possibility to assembly two or more mats in one room. In such a case the mats have to be connected in parallel. The matter concerns large rooms first of all. NOTICE: Before executing the parallel connection of two or more mats it is necessary to lead all the cold tail to the installation cable boxes. It is absolutely unacceptable to make such connections and place them below the floor. 3

4 Selecting the correct power unit Depending on the application and the type of a room we recommend the mats with the power unit amounting to 100 W/m or 160 W/m. The correct selection is specified in Table I. Table I.

7 Temperature control The temperature controller constitutes an essential component of the floor heating system. It enables the heating mats to operate correctly. The selection of the correct type of a temperature controller provides an optimal heating effect according to the consumer's expectations. If the heating mats constitute exclusively the supplement to the existing heating system (basic), then the user is interested in the so-called effect of "warm floor" (e.g. reheating the bathroom) - in such a case use the temperature controllers with the floor sensor. The floor sensor allows for keeping the constant temperature of the floor. If the heating mats constitute the basic heating source then the user is interested in achieving the optimal air temperature in a room - in such a case use the temperature controllers measuring air temperature, i.e. the air temperature controllers or the air-floor temperature controllers (in this case the floor sensor protects the heating cables against overheating). The temperature controller provides the constant temperature of the floor or air, e.g. Elektra MICROLINE OTN, Elektra ELR 10. If you want to program the correct temperature in the specified time of a day or night you have to apply the temperature controller with a programme control, e.g. Elektra MICROLINE OCC, Elektra DIGI, Elektra EUROSTER 000p. 7

8 Requirements conditioning the assembly of mats The heating mats must be assembled according to the following instructions. The connection to the power network has to be performed by an authorised electrician! The heating mat can not be excessively tightened and stressed either. It is unacceptable to cut the heating cable - only the mesh to which the heating cable is fastened may be cut. The heating mats should not be assembled in places where the permanent furniture and elements are planned (e.g. bathtub, cupboards without stems, etc.). The mat should not cross the expansion gaps in the floor. In order to prevent the possible cracks of the tiles it is necessary to use an elastic joint. 8

9 Preparatory work The following should be completed during the electrical works phase: 1) choose a location for the temperature controller ) mount the electric cable box, where the temperature controller will be placed 3) lead the power supply cable into the box 4) lead two protective pipes out of the cable box, in which the following should be placed at the time of the installation of the heating mat: - floor sensor (optional) - cold tails of the mat (fig. 1) NOTICE: NOTICE: The protective pipes located at the boundary between the wall and floor may not be bent at a right angle. The pilot (an elastic cable) located inside the pipes will allow for an easy introduction of the floor sensor and the cold tails of the mat (following plastering or the laying of tiles). The temperature controller must be placed on the outer wall of the bathroom in order to protect it from moisture damage. 9

Then it has to be done the so-called "dry trial run", i.e. the mat has to be spread in such a way that the cables face the basis (the mesh upwards). Depending on the planned surface that has to be heated, form the mat by cutting the mesh with scissors (drawing a). Do not damage the heating cable! In the place of the mat's slit the cable has to be carefully straightened and the parts of a mat have to be arranged side by side in such a way so they do not overlap.

11 Before sticking the heating mat to the surface it is necessary to install the floor temperature sensor. It is placed at the end of a 4-meter long cable. The cable with the sensor place in a protective tube. Place a protective tube in a 10 mm long furrow in the floor's surface and lead it under the plaster to the installation cable box where the temperature controller will be assembled. The temperature sensor should be placed as possible in the centre of the heated room. NOTICE: It is prohibited to bend a protective tube at right angle, the curvature has to be kept (drawing 5). To the installation cable box (after sticking the heating mat) will be also inserted the so-called cold tails of the mat. It is important to find a correct location for the installation cable box both due to aesthetic (the temperature controller visible on the wall) and as regards the practice. The bathroom temperature controller should not operate in the circumstances of increased humidity then it has to be placed on the outside wall of a bathroom. When the cable of the temperature sensor or the cold tails of a mat will turn out to be too short, they may be extended by assembling an intermediate cable box. NOTICE: The temperature sensor has to be placed at the same distance from heating cables. 11

13 Arranging the heating mat NOTICE: Before sticking the heating mat, it is necessary to measure the resistance value of the core and heating cables' insulation, install the box, the cables' protective tubes and the temperature sensor. With the use of a serrate spatula spread a layer of the adhesive mortar on the cleaned basis and then lay the heating mat (in such a way that the heating cables face the basis) and close tight it gently so it "drowns" completely. If necessary, level a layer of the adhesive to eliminate air bubbles, deformations and swellings. Then, after it dries up, spread a layer of the adhesive mortar in such a way so the thickness of it allows for laying ceramic tiles (terracotta, glaze). In case when the heating mats are placed under the carpeting, PVC or mosaic, you may use the self-levelling mix. In this situation it is necessary to remember that the mat has to be attached to the surface before drowning it in the self-levelling mix so it does not float to the top surface of the mix.

14 After arranging It is necessary to measure again the resistance value of the core and heating cables' insulation and compare it to the original value. It is recommended that the electric terminals are made with the use of a three- core conductor 3 x 1,5 mm. The heating system may be started only when the adhesive mortar or selflevelling mix is completely dry - the time of drying up is specified in the producer's instructions.

15 Connecting The connection of a heating mat to the electric system should be performed exclusively with the use of a temperature controller (drawing 7). The heating mat can not be connected to the electric system with the use of the plug-in sockets. NOTICE: The protective cables of the mat (green - yellow) have to be linked to a protective cable (green-yellow) of the electric system with the use of a special clamp in a temperature controller. If such a clamp does not exist, the connection has to be made separately and placed in the installation cable box.

16 Electric shock protection The copper shield linked to the PE cable provides full safety while using heating cables (drawing 7). In heating systems a diverse power switch has to be used with sensitivity D 30 ma. The time of the voltage disconnection in this protection system can not exceed 0, sec. A diverse power switch may be the same for various receivers. The resistance of the heating cable's insulation, measured with the use of a device with the voltage rating of 1000V can not be lower than 0,5 MW. Operating The operation is limited to the adjustment of desirable temperature of the floor with the use of a temperature controller. An user has to remember that the whole surface of the floor constitutes his heating system and for this reason he should not introduce any changes in furnishings or the rooms' destination which could make difficult the release of the heat by the floor. It is not recommended to place on the floor some large parts of furnishing, e.g. mattresses or furniture without stems, which would entirely stick to the surface. It is permitted to drill holes in the floor but after making sure where are placed the mat's heating cables (on the basis of the after-execution documentation or the route of the mat's heating cable located with the use of an appropriate device). 16
