5. Configuración e instalación
Installation of the Nexans millimat/100 N-HEAT electric underfloor heating system should be performed by a qualified electrician or heating professional in accordance with local building codes and electrical regulations.
General Installation Steps (Consult full installation guide for details):
- Prepare el contrapiso: Asegúrese de que el contrapiso esté limpio, seco, nivelado y libre de residuos. Aplique una imprimación adecuada si es necesario.
- Diseño del tapete del plan: Determine the optimal placement of the heating mat, avoiding permanent fixtures and ensuring even heat distribution.
- Instalar sensor de piso: Place the floor temperature sensor in a conduit between two heating cables, ensuring it is centered and accessible for future maintenance.
- Coloque la estera calefactora: Unroll the mat onto the prepared subfloor. The mesh can be cut and turned to fit the room shape, but never cut the heating cable itself.
- Conexión eléctrica: Connect the cold lead of the heating mat and the floor sensor to the thermostat. The thermostat must be connected to the main power supply by a qualified electrician.
- Aplicar revestimiento de suelo: Once the mat and sensor are installed and tested, apply a suitable leveling compound or tile adhesive over the mat before installing the final floor covering.
