
The cable must not be placed either under such furnishings as bathtubs, shower baths, toilets and the
like or under furniture that does not allow air to circulate.

The distance between the heating part of the cable and the wall should not be less than 50 mm.

The concrete mixture must be so compact that the layer contains no air bubbles, cavities and the like
and ensures full contact with the heating cable. Compacting must be done carefully, by hand, to
prevent damaging the cable. In no case may immersion vibrators be used.

The concrete mixture must contain so-called plasticizers.

When concreting, it is necessary to bear in mind that in case of a break in work longer than 60 minutes
the concreted areas do not join fully. Therefore, in case of a longer break, it is necessary to create an
adhesive connecting bridge (e.g., by penetrating or in another manner).

The areas where the heating cable is to be placed must be insulated thermally using a layer of extruded
polystyrene or similar insulation 80 mm thick.

The thermal insulation must be covered with a concrete layer 40 mm thick upon which the heating
cable is laid.

When installing the reinforcing steel, you must pay close attention to avoid damaging the cable’s
insulation.
Procedure:

Cover the hydro-insulated foundation with a thermal-insulation layer, then cover this layer with a 4 cm
layer of concrete.

Allow the concrete to set fully.

Clean the concrete area, remove any sharp objects and coat it using a suitable penetrating solution.

Place the heating cable in an open-looping pattern in accordance with the required output.

Fix the heating cable (e.g., using Grufast fastening strips) so that it cannot move during further
concreting.

In humid spaces, connect the protective braiding of the cable to the protective grounding connection
for the room.

Measure the resistance of the heating circuit and the insulation resistance and record the measured
values in the certificate of warranty.

Cover the cable with a concrete layer up to the required height. After concreting is finished, measure
the resistance values again and record them in the certificate of warranty.

Wait at least 28 days after installation before putting the mat into operation, so that the concrete will
be set fully.

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.
