
To allow for expansion around the periphery of the room between the baseboards and the floor
tiles, use an expansion profile or fill the spaces with silicone sealing cement. The distance
between the heating mat and the wall must not be less than 50 mm.

The mat 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 maximum thermal resistance
between the heating part and the room may be R=0.18 m
2
K/W.

The installation must allow for disconnecting the mat or mats at both poles. The minimum
distance of disconnected contacts must be 3,5mm.

The label on the cold end of the heating mat shows the serial number and production date. The
label on the mat’s packaging shows type, dimensions and area of the mat, total output, output
per 1m
2 , as well as the mat’s supply voltage and electrical resistance.

Before and after laying the mats, it is necessary to measure the resistance of the heating circuit.
The measured values should be equal. Record the measured values in the certificate of
warranty.

Before and after laying the cables, it is necessary to measure the insulation resistance between
the heating conductor and the protective braiding. This measured value may not be less than
0.5MΩ. Record the measured values in the certificate of warranty.

Before opening the package with the heating mat, it is necessary to check whether the data on
the label is in accordance with your requested product.

In case of any discrepancies, you should report these immediately to the manufacturer or
supplier and discontinue the work completely.

You must draw the scheme of the heating mat layout in the certificate of warranty, indicating
the exact distance of the connections of the supply cable and heating part from the walls of the
building. Record the serial number and production number of the heating mat that are stated on
the label on the mat’s cold end, then insert/stick this label into the connection box.

The supplier must inform other construction suppliers about the heating unit installed in the
floor and of the related risks.

A sheet of paper with information about the heating system must be permanently kept in the
switch box of the heating system and passed on to any new owner or tenant.

When installing the mats, the CSN 33-2000-7-753/HD 3844-7-753; EN 50559 standard
requirements must be met.

The product is produced according to the EN 60335-2-96/IEC 60335-2-96 standard and must
be installed in accordance with the national regulations for electrical installation.

The heating mat 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 mat extends under zone 0, the mat must be connected via a residual current
device with a trip current of 10 mA.

An insufficient thermal insulation layer below the heating system may cause significant
thermal loss (warmth moving downwards). Recommended thermal insulation is 70–80mm 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, we
recommend installing F-boards in a depth of 6mm or 10mm to accelerate the warming of the
surface and to reduce the thermal loss. This material is installed into the adhesive sealing
cement that was shaped by a notched spreader and the heating mat is placed directly onto its
surface. The F-boards do not need to be penetrated.
