FLOOR HEATING MATS
GENERAL TERMS AND CONDITIONS

Heating mats may be operated only as a part of building structures. Fixing the heating cable
to the fiberglass fabric during manufacture by gluing is regarded to be only a temporary bond.
The heating mat is intended for installation in wet construction processes (concrete, adhesive
and “self-leveling” sealing materials based on cement fulfilling thermal flexibility
requirements – during application it is necessary to follow the manufacturer’s instructions).
When in use, the heating mat must be in full contact with these materials and free from air
bubbles.

The mat may be adjusted only as shown in pictures 1 – 3, and in no case may it be shortened.
You may shorten only the cold connection ends, as required. The connection joining the cold
end and the heating cable may not be installed in a bend. The heating cables of the heating
mats may neither touch nor cross one another. The minimum distance between the cables is 30
mm. If the heating or power supply cables are damaged, they must be replaced or repaired by
the manufacturer, its service technician or a similarly qualified person in order to prevent a
dangerous situation from arising. Do not use nails or screws to install the cables!

When installing the cables, the diameter of a bend in the cable must be at least eight times
greater than the cable’s diameter.

The heating cable must be supplied with electricity by means of a residual current circuit
breaker with rated actuating current of IΔn≤30mA, except for those mats with protective
braiding that are installed in a dry environment. We recommend that each heating unit/circuit
be equipped with a separate residual current device.

For safety reasons, heating mats may not be installed in walls.
 The heating mats may be stored at temperatures from +10°C to +35°C and installed at
temperatures from +5°C to +30°C. When in operation, they may not be exposed to
temperatures exceeding 70°C.

During removal from packaging , manipulation and installation of the mat take special care to
avoid mechanical damage to the mat – check the heating cable visually before pouring the
building material.

The heating mat may not be installed on irregular surfaces

The heating mat is primarily intended for installation with the supporting material facing the
base. It can, however, be installed the other way round.

In case that mats are laid in an area larger than 20m 2
or with a diagonal greater than 7m, it is
necessary to account for expansion of the foundation materials. The heating cable must not
cross the expansion joints. The non-heating connecting cables located at the expansion joints
must be laid loosely in a protective tube. All installed elements – cold connection end,
thermostat’s probe – where they pass from the wall to the floor must be placed in installation
tubes and must allow for movement of the floor and wall relative to one another.
