FLOOR HEATING MATS
1. 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 tempo
-
rary bond. The heating mat is intended for installation in wet construction processes (concrete, adhesive and “self- levelling” 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
• 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 20 m
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.
• 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=0.12 m
2
K/W.
• The installation must allow for disconnecting the mat or mats at both poles (which condition may be provided using the thermostat).
• 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 certi
-
ficate 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, and 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 standard requirements must be met.
• The product is produced according to the CSN EN 60335- 2- 96/IEC 60335- 2- 96 standard and must be installed in accordance with the national regulations for electrical installation.
• 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 ISOLA- 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 ISOLA- boards do not need to be
penetrated.
• This appliance is not intended for use by persons (including children) whose lack of physical, sensory or mental ability or lack of experience and knowledge prevents them from
safely using the appliance, unless they are supervised or have received instructions regarding the use of the appliance from a person who is responsible for their safety. Children
should be supervised in order to prevent them from playing with the appliance.
