An insufficient thermal insulation layer below the heating system may cause significant
thermal loss (warmth moving downwards). Recommended thermal insulation is 70–80 mm of
extruded polystyrene or similar thermal insulation materials. In case of reconstruction, where
there is not space to install the thermal insulation to a sufficient depth on the existing tiles, and
the system is anticipated to be used only for a short intervals (up to 6 hours per day) to increase
convenience but not to heat the premises, we recommend installing F– board in a depth of 6
and 10 mm to accelerate the warming of the surface and to slightly reduce the thermal loss. F –
board is installed into the adhesive sealing cement shaped by the notched spreader and the
heating mat is placed directly onto its surface, F – board does not need to be penetrated.
The cable may be placed neither under furnishings such as bathtubs, shower baths, toilet, etc.,
nor under furniture that does not allow air to circulate. The maximum thermal between the
heating part and the room may be R=0.15 m
2
K/W.
The distance between the heating part of the cable and the wall should not be less than 50 mm.
It is forbidden to cover the heating cable with construction foil or tape.
Heating cables can be fixed to the base by tape only at isolated points and without air gaps.
When putting the cable into operation, each layer must be fully set – see the instruction for use
and recommendation from the manufacturer of the materials.
Materials used in finishing the floor surface (glue for tiles, carpet, parquets, etc.) must be
approved by their respective manufacturers for use on floors under thermal stress.
Any manner of use different from those specified in this user guide should be consulted with
the manufacturer.
The presence of the heating cable must be made evident by the posting caution signs or
markings in the fuse box and be part of electrical documentation.
The HD 3844-7-753; EN 50559 standards requirements must be met. El. installation must be
in accordance with national regulations.
The heating cable can be installed in the bathroom even under zone 0 under the condition that
the connector and the end of the heating cable are installed outside this zone.
If part of a heating cable extends under zone 0, the heating cable must be connected via a
residual current device with a trip current of 10 mA.
The user must be instructed by the supplier regarding the installation of floor heating. This fact
is stated on a label which comes with the product and must be glued into the switchboard: this
label also informs readers that the making of openings is prohibited, as is covering the floor
with furnishings or fittings without leaving at least a 4 cm gap between the floor and the
bottom surface.
Caution:
Non UV protection –not to be used for outdoor application.
