• Unroll the mat, adhesive side down (Fig. 4.4 a);
• Ensure that the cold lead is long enough to be connected to the thermostat or

channel in the subfloor to receive the cold lead/heating cable (black) junction.
The junction has an extra insulation sheath and a slightly larger diameter than the
heating cable;
• Continue to unroll the EFMA system on the floor, working around the stationary
elements marked out beforehand (see Section 4.4.1);
• As needed, reposition EFMA: its adhesive allows it to be positioned more than
once.
• You may use hot glue or tape to fasten the EFMA to the subfloor;
