Installation

Please Note: This is a brief guide. Always refer to the full installation manual for comprehensive instructions.

1. Plan Your Layout:

• Divide the floor into a series of rectangles. Use these measurements to calculate the number and sizes of mats needed, excluding permanent or static fixtures from your calculations.

2. Prepare the Subfloor:

• For screed over concrete floors, lay insulation boards to minimize heat loss and ensure quicker warm-up times.

3. Lay the Heating Mat:

• Start with the first run of the mat. Cut the mat (leaving the cable intact) at the end of each run, turn it 90° or 180°, and continue laying.
• Once the area is covered, adjust the mat so that the loops are evenly spaced.
• Secure the mat to the subfloor using the special tape provided.

4. Electrical Connections:

• Install an RCD fused spur to power the thermostatic controller/programmer and the mat system.
• Lay the temperature probe from the timer-thermostat onto the floor, position it equidistant between two cable loops, and secure it to the surface.
• Position the unheated power supply cable from the end of the mat system near the thermostat.
• Make all necessary connections to the power supply. Run the heaters for no more than 10 minutes to ensure they are heating up properly.

5. Finish the Flooring:

• Option 1: Apply a thin, self-levelling screed over the mat and allow it to dry completely before laying tiles.
• Option 2: Directly trowel flexible tile adhesive over the mat and lay the floor tiles.
• After grouting, let the tile adhesive cure fully before switching on the system.
