4.2 Preparing the Subfloor
– Clean and remove any debris, or protruding objects that could damage the
heating cable;
– Subfloor cracks must be filled with polyester wood filler (only for self-leveller);
– The subfloor must be solidly fastened in place to prevent movement;
– The application of a floor levelling product is recommended to prevent future
damage to the ceramic caused by subfloor movement;
– For concrete subfloors, apply a surface sealer that is compatible with electrical
heating systems in accordance with the cement glue manufacturer’s instruc-
tions. Completely coat the surface;
– Let dry before installing the Therma Cable system (refer to the sealer’s instruc-
tions for drying time).

– On the floor of an empty room (under construction or major renovations), draw
the location of stationary elements (toilet, bath, shower, counters, drawers,
permanent furnishings) that will be installed later. These marks will outline the
heating area to ensure the Therma Cable system is not placed under these
stationary elements;
– Ouellet Canada Inc. strongly recommended to install two temperature sensors
per room, where the Therma Cable will be installed. The sensor probes must be
installed between the spires of the heating cable and at a distance of 306 mm
(12’’) from each other. Note that only one sensor is connected to the thermostat,
