Schluter - DITRA-HEAT-E-HK-RK Heating Cable Repair Kit

Schluter-DITRA-HEAT-E-HK are twisted-pair heating cables designed for integration with the DITRA-HEAT uncoupling membrane in interior heated floors. Important tips for selecting Schluter-DITRA-HEAT heating cables: Do not purchase heating cables for the entire tiled area—this will be too much! Very important: NEVER CUT OR MODIFY the heating cable. This will alter its resistance, potentially damaging it and leading to overheating. The cable can also be installed alternately at intervals of three, then two, studs, in specific areas or across the entire floor. This practice can be used to increase heating power (e.g., on uninsulated or below-grade concrete subfloors) or to use a longer cable in a given area (e.g., when the three-staple arrangement does not allow for minimum spacing from walls, partitions, etc.). A four-staple arrangement is not recommended, as it may result in uneven temperatures. Minimum distance from walls, partitions, and fixed cabinets: 2" (50 mm). Minimum distance from heat sources (electric baseboard heaters, fireplaces, forced-air heating systems, etc.): 8" (200 mm). Minimum distance from waste drains and forced-air ducts: 4" (100 mm). Minimum distance from the centerline of toilet drains: 7" (180 mm). NEVER install heating cables under sink vanities with no air gaps underneath, bathtub platforms, and freestanding bathtubs with no air gaps underneath, or in kitchen cabinets, islands, and other fixtures, or in small storage or clothing closets where the flooring may extend beyond. Excessive heat will build up in such enclosed spaces, which could cause overheating. NEVER run the heating cable under or through a wall, partition, or through a floor. NEVER install the connector (the black plastic piece that joins the cold wire to the gray heating cable) in a wall, as this could cause overheating, system failure, or damage. The connector must be completely recessed under the flooring, as explained in the heating cable installation instructions. It is helpful to provide a buffer zone, as it is impossible to predict exactly where the heating cable will terminate. The buffer zone is an area where heating is not essential and is not intended to accommodate cables, e.g., behind a toilet or near a door opening. This area allows excess heating cable to be concealed. Heating cables can also be installed 6" (150 mm) from the walls to create a buffer zone. Heating cable testing must be performed while still in its spool, as well as at two subsequent stages during installation, to ensure cable quality and for warranty purposes. A megohmmeter is required to perform the insulation resistance test on the heating cables. It is strongly recommended that this be performed. Please consult a qualified electrician before ordering DITRA-HEAT heating cables to select the correct voltage for your installation.

• Cables insert into the membrane without fasteners
• There is no need to cover the cables with a self-leveling compound, which greatly speeds up installation
• Install without a return line to the thermostat
• Produce virtually zero electromagnetic fields
