The thermostat should be positioned at the coldest point and protected from direct
sunlight. The thermostat shall not lie continuously in water. The connection cable
shall not lie in water and shall not be exposed to direct sunlight. Do not fasten the
heating cable by means of adhesive tapes with aggressive adhesive.
The mains cable, the thermostat and the transition between the heating cable and
the thermostat shall not be laid in the gutter but rather should project beyond
the edge of the gutter. In order to guarantee better temperature transfer to the
thermostat, this should be placed such that the round contact surface is in direct
contact with the outside of the metal gutter.
Avoid damage to the heating cable due to sharp edges. (Use edge protection!)
The heating cable is self-supporting up to 4 metres in downpipes. Adequate strain
relief must be provided. Sharp edges, such as the transition between the gutter and
the downpipe, should be secured with edge protection.
The mains connection plug shall be connected only in a dry room.
Heating cables shall not be laid twisted.
Do not lay the heating cable along parts of the building that warm up or get hot.
(chimneys, hot piping)
Use edge protection at the transition between the gutter and the downpipe!
There shall be no tensile, compressive or torsional loads on the cable and its
connections with the thermostat and mains cable. Never separate, open or damage
the system by force as this can impair the function of the device and void the war-
ranty. The IP X7 (waterproof) protection category is likewise no longer guaranteed
with this.
For safety reasons, earth pipework, metal guttering, metal conduits and sheathing
before laying. Ensure that all metal parts are earthed before starting with the
installation. The conductivity of the complete system must be checked and any
additional earthing connections required must be established.
The heating cable shall not be used on bitumen.
The heating cable and the complete device are maintenance-free. However, they
must be subjected to a visual check at least once per year. In the event of visible
damage or wear (cracks, cuts, deformation, embrittlement, charred points or disco-
lourations) to the insulation, the complete heating cable must be replaced.
The heating cable must be disconnected from the power supply before starting
with a visual check.
If a breaker for the heating cable has tripped, the breaker shall not be reset until
the cause has been identified and the complete device and installation checked for
possible damage or wear by a qualified electrician.
The heating cable shall not be fitted with outside temperatures < +5°C.
If the heating cable is stiff (due to cold), it must be unwound and connected for a
few minutes until it has become warm and flexible before it can be installed.
Never connect a heating cable to the mains when it is still coiled up.
The minimum bend radius of Rmin = 35 mm shall be complied with.
