2. பாதுகாப்பு வழிமுறைகள்

Installation must be carried out by a qualified electrician in accordance with local electrical regulations and standards.
Always disconnect the power supply before performing any installation, maintenance, or repair work.
The heating mat must not be cut or shortened. Only the support fabric network can be cut to adjust the mat's layout.
Ensure the heating mat is not overlapped or installed in areas where it could be punctured or damaged.
A Residual Current Device (RCD) with a tripping current of 30 mA is required for protection.
Do not install the heating mat under fixed furniture without legs or heavy objects that could trap heat.
Keep the thermostat away from direct sunlight, drafts, or other heat sources that could affect its temperature readings.

5. நிறுவல் வழிகாட்டி

The Mi-Heat aluminum heating mat is designed for dry installation, making it suitable for floating floor coverings. This section outlines the general steps for installation. Always consult a qualified electrician for electrical connections.

5.1. Preparation of the Subfloor

Ensure the subfloor is clean, dry, level, and free from sharp objects.
Install appropriate impact sound insulation (3-5mm recommended) over the subfloor.

Electric underfloor heating installation layers — Figure 5.1: Diagram illustrating the layers of an electric underfloor heating installation, showing the underground, impact sound insulation, ALU heating mat, and laminate/parquet flooring.

5.2. Laying the Heating Mat

Unroll the aluminum heating mat over the impact sound insulation.
To change direction or fit the mat around obstacles, only cut the support fabric network. Do not cut the heating cable itself.
Use the aluminum tape to secure the mat sections and ensure good thermal contact.
Ensure the heating cables are evenly spaced and do not overlap.

Underfloor heating mat installation options — Figure 5.2: Various installation options for the heating mat, demonstrating how to relocate, create corner recesses, and form individual transfer shapes by cutting only the support fabric.

5.3. Thermostat and Sensor Installation

Install the E51 digital thermostat in a standard electrical box at a suitable height on the wall.
Route the external floor sensor cable through one of the corrugated pipes and place the sensor centrally between two heating cables, ensuring it is not directly over a heating element. The corrugated pipe allows for future replacement of the sensor.
Route the heating mat's connection cable through the second corrugated pipe to the thermostat.
Connect the heating mat, floor sensor, and power supply to the thermostat according to the wiring diagram provided with the thermostat. This must be done by a qualified electrician.

5.4. Final Flooring Installation

Once the heating mat and thermostat are installed and tested, you can proceed with laying your chosen floating floor covering (laminate, parquet, vinyl on HDF backing) directly over the aluminum heating mat. Ensure the flooring manufacturer's guidelines for underfloor heating compatibility are followed.
