3 Deviflex DTIE- and DTIE 17 heating cables Deviflex type DTIE is a 2-wire heating cable. The cable is CE-Marked, and NEMKO certified in accordance with IEC The cable is suitable for both indoor and outdoor use, and may be attached directly to any mesh reinforcement. Please consult the table below for the correct choice of cable. Areas of use Installation Normal W/m2 Max.

4 General Installation instructions The following guidelines must be observed when installing the heating cable: The heating cable must be installed with a fixed connection (not a plug socket). An authorized electrician must connect the heating cable to the thermostat. The specified maximum output for various installation and operating conditions must be respected. The heating cable must be protected against mechanical stress at all times and must never be stretched. Clean the surface and remove any sharp objects. The flex diameter of the cable must not be less than 6 x the cable diameter. Ensure that the cable do not touch or cross one another. Do not lay the connection box and the end of the heating cable in wet areas such as showers or under bathtubs, etc Do not lay the heating cable under built-in baths, cupboards, walls, etc. Connect the earth wire of the heating cable in accordance with regulations. Do not shorten the heating cable as this will increase the output per metre cable. Check the insulation resistance and the resistance of the heating cable once it has been installed, both before and after the concrete is poured. The resistance of the cable must be as specified on the label: -5 +%. It should still be possible to move the heating cable after attaching any type of fixing strips. The heating cable must be equipped with a circuit breaker. In addition, we recommend the use of a Devireg thermostat. The cable is marked every one-meter but please note that smaller deviations compared to the cable s actual length might occur. The meter marking is only meant as a help when laying out the cable. Fig. 1 The heating cable should not be installed at temperatures below 7 C. If you have to lay the cable at low temperatures, try connecting the cable for a short while as this will make it easier to install. Please note that the cable must, in this case, be rolled out to keep the cable temperature from getting too high.

5 Installing the cable in thin floor constructions Thin floor constructions are particularly relevant in connection with house renovations and in places where construction height and drying times, etc. must be taken into account. Please note that, in case of thin floor constructions, it is important to choose the right cable for the floor in question. The C-C distance must not exceed 12 cm. DEVI offers the complete heating solution. Any instructions relating to the concrete mixture must be closely observed, and the supplier of the floor covering must be informed that underfloor heating has been installed in order to ensure that the most suitable product is chosen. When installing a wood/laminate floor, we recommend the use of a combination thermostat that limits the floor temperature, such as the Devireg 132, 522, 535.

In wet rooms, the membrane should be applied to the top of the concrete.

6 Installing the heating cable in cement floors Lay the heating cable evenly across the floor, avoiding any obstacles. The surface must be clean and free from sharp objects. For quick and simple installation, we recommend the use of Devifast fixing strips. Fig. 4 A Devireg thermostat should be used at all times. If a floor sensor is used, it should be installed in a pipe. The pipe should be placed in the concrete between the cable loops and the end of the pipe must be sealed. We recommend that you draw a simple sketch showing the cable s position. A decision must be made as to whether or not the floor should be insulated. This depends on the existing floor construction, the location of the floor, the construction height, etc. The underfloor heating must not be used until the concrete has hardened, i.e. after approximately 6 8 weeks or as specified.

7 Installing deviflex in market gardens and greenhouses, etc. To improve growing conditions for plants the installed output must not exceed 90 W/m 2 when using Deviflex cables. The heating cable should be installed at sufficient depth in order to ensure that it is not damaged when the soil is worked, i.e. at a depth of 25 cm with a covering of netting wire, or at a depth of cm with a covering of flagstones or similar.

8 Control and adjustment Deviflex heating cables must be thermostat controlled. Optimum control will be achieved with the use of Devireg electronic thermostats designed to provide rapid and effective control taking both comfort and economy into consideration. A wide range of Devireg thermostats is available to meet various requirements for individual installations. The sensor may be extended by up to 50 m using min. 1.5 mm 2 installation cable.
