User Manual

GENERAL INFORMATION TO INSTALLATION

• Never electrically connect or turn the heating mats on while coiled.
• Only the heating mat cold lead wires are allowed to be lengthened or shortened during the installation.
• Never electrically connect or shorten the heating wires.
• Always install the electrical underfloor heating mat strictly using an all pole disconnection (e.g. relay, power contacted) with a contact opening of minimum 3 mm.
• Multiple heating mats must be connected parallel in a recessed electrical box.
• Always connect the braided shield or screen to the PE ground conductor.
• Always install the thermostat outside of the protected zone 2, according to VDE 0100.
• Always connect the electrical underfloor heating mat, by means of an electrical box, firmly to the power supply 230 VAC (3×1,5mm²). Electrical installation is only allowed according to DIN-VDE or local regulations and installation by a qualified electrician.
• Never exceed the total amperage of the thermostat (refer to thermostat specifications) by parallel connected heating mats.
• Never cross or fold the heating wires.
• Never bend the heating cables less than 30 mm radius at the turnings.
• Always operate the electrical underfloor heating mat with a ground fault circuit breaker (30mA).
• Never impact the termination joints more than 120 N.
• The connation’s cannot be folded or damaged.
• Never install the heating cable over a building expansion joint.
• The minimum installation temperature is +5°C.
• Never install the mats through or behind insulation material, under cabinets, under fixed objects or in small closets. Excessive heat will build up in these small spaces and the fasteners (nails, screws, etc.) used to install the fixed objects could damage the mat.
• The minimum distance of the heating mat to the wall or to ascending components (e.g. bathtubs, shower trays) must be 5 cm. The distance to conductive building parts (e.g. hot water pipes) must be at least 3 cm. In order to remain flexible in the positioning of the furniture, or in cases where the final position of the furniture is not yet known (especially in rental apartments and houses), a distance of 60 cm to the partition wall should be kept free.
• Always record the mat resistance readings before and after the installation.
• Always make sure all electrical work is executed by qualified persons in accordance with the local building regulations, electrical codes and the latest VDE regulations (for example VDE 0700 Part 753, VDE 0700 Part 701 and DIN VDE 1264-3).
• Always verify that the existing floor thermal insulation complies with the latest technical standards and regulations. Therefore, a high energy consumption is excluded.
• It is not allowed to change the surface area of the subfloor, on which the heating mat is installed. Underlaying materials other than mortar or screed are not allowed to be used.
• Never install the electrical heating mat in walls or ceilings.
• We guarantee that our products are free from defects in materials and workmanship. Products that have been mechanically damaged due to incorrect connection or due to disregard of the terms of operating rules and servicing, are not subject to warranty repairs, replacement or return.
• The subfloor should be even, secure, solid and with an appropriate load capacity. The surface has to be dry, clean, free of grease, dust and sharp objects.
• If the subfloor is uneven, it is necessary to level it, using a self-leveling floor compound before installation of the heating section in order to avoid air cavities underneath the heating section.
• Completely cover the termination sleeves with mortar, screed or tile glue.
• Never put the underfloor heating system into operation before the tile adhesive, mortar or screed is fully dry.
• Always use materials for the installation which are certified by the manufacturer for underfloor heating systems.
• Always install the cold lead cable of the heating mat inside a seperate corrugated tube (DIN EN 61386-1).
• Always install the floor temperature sensor cable inside a separate corrugated tube (DIN EN 61386-1).
• The heating mat should not be exposed to temperatures above 80°C.

INSTALLATION PLAN
Draw the layout of the electrical underfloor heating mat and write down the zones free of the heating mat and spacings at the surrounding walls. The distance of the electrical heating mat and any conductive parts of the building have to be at a minimum of 30 mm. (for example, water pipe).

INSTALLATION

SUBFLOOR PREPARATION

The subfloor should be even, secure, solid and with an appropriate load capacity. The surface has to be dry, clean, free of grease, dust and sharp objects. If the subfloor is uneven, it is necessary to level it, using a self leveling floor compound before installation of the heating mat, in order to avoid air cavities underneath the heating mat. Never install the heating cable over a building expansion joint.
THERMOSTAT INSTALLATION PREPARATION

Chisel out channels for the power supply wires, cold leads and temperature sensor in the wall and floor (Attention! Cold leads and sensor cable have to be installed into two separate corrugation tubes!). A standard plastic round recessed electrical box with 230 VAC power supply is preferred for installation at the chosen thermostat location. A ground fault circuit breaker (30 mA) should be used for the 230 VAC heating mat circuit.
MAT ADJUSTMENT

Fix the heating mat with the fibre mesh side down to the subfloor according to your layout. Adjust the mat to the heating area layout by cutting and turning the fibre mesh (Attention! Do not cut or damage the heating cable!). After positioning the heating mat into the intended form, press the heating mat firmly to the subfloor. The fibre mesh has to be laid without any folds. The heating mat should be fixed using 4 to 6 dowels per m² to prevent the heating mat from swimming when using leveling screed.
KEEPING THE SAFETY DISTANCE
Keep a safety distance of around 4-6 cm (it is not permitted to install under the minimum distance of 3 cm.) between the turnings of the mat. Wear soft elastic sole shoes and cover the mat surface with plywood boards or other material in order to prevent damage of the heating mat cables during installation. Take caution not to drop sharp objects or stepping on the heating cables in order to avoid damage to the heating mat.
INSTALLATION WITH DIFFERENT FLOOR FINISHINGS
PVC and carpet floor finishings: The electrical underfloor heating has to be covered with around 5-10 mm leveling material. Insulation values and thicknesses of floor finishing should not exceed those stated under THERMOSTAT INSTALLATION AND FLOOR CONSTRUCTION.
If the subfloor is uneven, it is necessary to level it using a self-leveling floor compound, before installation of the heating mat in order to avoid air pockets underneath the heating mat. Never install the heating cable over a building expansion joint.
FLOOR TEMPERATURE SENSOR INSTALLATION

Sensor installation
The floor temperature sensor cable has to be placed into a separate corrugated tube according to EN 61386-1.
The sensor should be placed centrally between the heating conductor. Route the heating mat cold lead through the second corrugated tube. Do not cross the cold lead over or place it closer than about 2 cm to the mat heating wires! A standard plastic round recessed electrical box with 230 VAC power supply is preferred for installation at the chosen thermostat location. A ground fault circuit breaker (30 mA) should be used for the 230 VAC heating mat circuit. Ensure that the sensor can be placed into and removed from the corrugated tube (Ø16mm); once during installation of the tubing and again before installation of the floor finish!
TILE ADHESIVE OR SCREED LAYING
Be careful not to damage the heating conductor insulation with the tile trowel during the laying of the tile adhesive or screed. The heating wire has to be completely covered over the full extent of the heating mat. If necessary after the laying of the tile adhesive or screed, the heating mat may be adjusted by slightly lifting and then pressing it firmly back into the laying material again.
For different coverings, e.g. PVC or carpet, the electrical underfloor heating section has to be completely covered with a self-leveling floor compound about 5-10 mm. The heat transition coefficient (conductance) of the leveling material is not permitted to exceed Rλ= 0,15 m² K/W and the leveling material exposure temperature resistance has to be minimum 50°C. The appropriate conductance of the floor finishing is found under THERMOSTAT INSTALLATION AND FLOOR CONSTRUCTION in Fig. 4.
After the laying of the floor finish, measure and record the heating section and insulation resistance. Please retain the resistance readings record.
Once the tile adhesive is cured, grout the tiles with appropriate material. Tile expansion joints shall be provided at all adjoining building units and built-ins. These expansion joints are to be grouted by means of silicone. The product identification label (located at the cold lead) has to be placed at the electrical box.
