earthed before beginning installation. The entire system must be checked for consistency and any necessary additional earthing
connection must be created.
• Do not install the same heating cable simultaneously on different pipes. This could cause the heating cable to overheat and lead to
fire or electric shock.
• Never install the heating cable on a plastic pipe unless it is ensured that the pipe is always filled with water.
• If the heating cable is to be used to keep a plastic water pipe free from frost, the plastic water pipe must be completely wrapped with
an aluminium adhesive tape (Kerbl item no.: 222809) before installation and must only be used on temperature resistant water pipes
approved for hot water. (Fig. 5)
• The heating cable and the entire unit are maintenance-free but should still be regularly visually checked, at least once a year. In
the case of visible damage or wear (cracks, cuts, deformation, fragility, charred spots or discolouration) to the insulation, the entire
heating cable must be replaced.
• Disconnect the heating cable from the mains before starting a visual check.
• If the fuse (RCD) of the heating cable has tripped, the fuse must not be reset until the cause has been identified and the entire device
and the installation checked for potential damage or wear by a qualified electrician.
• The heating cable must not be installed at outside temperatures of < +5 °C.
• If the heating cable becomes stiff (due to cold), then it should be unwound and connected for a few minutes until it becomes warm
and pliable, before it can be installed.
• Never connect the heating cable to the power supply when it is still wound up. (Fig. 4)
• The heating cable and the power cable must be protected from damage and wear, e.g. through nibbling animals, ice, icicles, mecha-
nical stress etc..
• Do not staple, nail or otherwise affix the cable using unsuitable materials.
• The heating cable must not be connected outside of the heating cable (unplug it).
• The insulation must be no thicker than 13 mm. Inordinate insulation of the heating cable leads to overheating. You must ensure that
the insulation is not flammable. (Fig. 9 and 11)
• The power supply cord of this device cannot be replaced. The device must be discarded if the power supply cord becomes damaged.
• Please observe these safety notes and warnings. Retain the safety notes and warnings for later extension or monitoring of the cable
installation and give the instructions to the person responsible for the regular visual inspections.
2. Description
2.1 Construction
This frost protection heating cable consists of a resistance heating element (heating cable), thermostat and power cable. The metallic
jacket provides additional mechanical strength and the connection to the earthing.
A thermostat, built-in to regulate temperature, is between the thermistor and heating cable.
2.2 Correct use
The frost protection heating cable must only be used to keep metal cold water pipes and temperature-resistance plastic up to a diameter
of 40 mm free from frost. The heating cable should be installed flat to the underside of the pipe.
The regulations and safety instructions set out in these operating instructions must be complied with. Use of the cable in any other area
shall be deemed incorrect use. The manufacturer accepts no liability for any resulting physical and/or material damage.
