CABLE HEATING CIRCUITS

GENERAL TERMS AND CONDITIONS

 The heating part of the cable heating circuit may not be shortened or otherwise adjusted in any

way. Only the cold connection ends may be shortened, as needed.

 The connector joining the cold connection end and the heating circuit must not be installed in a

bend. The heating cables may neither touch nor cross one another. The minimum distance

between the cables is 30 mm, and the diameter of a bend must be at least eight times greater

than the cable’s diameter.

 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.

 The heating cable must be supplied with electricity by means of a residual current circuit

breaker with rated actuating current of I∆n ≤ 30mA. We recommend that each heating

unit/circuit be equipped with a separate residual current device. Over-current protection

provided.

 The heating cables may be stored at temperatures up to the resistance of the jacket (70°C) and

installed at a temperature of greater than -5°C. When in use, the cables may not be exposed to

temperatures exceeding 70°C.

 Before and after laying the cables, it is necessary to measure the resistance of the heating

circuits. The measured values should be equal. Record the measured values in the certificate of

warranty. The tolerance of the measured values is ±5–10%.

 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

0.5 MΩ. Record the measured values in the certificate of warranty.

 In case of any discrepancies, you should report these immediately to the manufacturer or

supplier and discontinue the work completely.

 Before using the heating cable, it is necessary to check whether the data on the label is in

accordance with your requested product.

 The supplier must inform other construction suppliers of the place where the heating unit is

installed and of the related risks.

 The perimeter of the area must be separated from the vertical structures by an expansion joint

(polystyrene, Mirelon, etc., up to 10 mm wide).

 In case that cables are laid in an area larger than 20 m

or with a diagonal greater than 7 m, it is

necessary to account for expansion of the foundation materials (expansion unit max. 25 m

for

mats up to 80 W/m

). The heating cable may 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, thermo regulator’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.
