AMBIENT HEATING SOLUTIONS
11. The power cable or buried cable with omnipolar switch may only be
replaced by a professional specialist electrical company enlisted or appro-
ved by the manufacturer. Heang elements, other components or parts of
the housing may only be replaced by a service organisaon enlisted by the
manufacturer.
If you yourself or someone enlisted by you carries out repairs, they will not
be covered by the guarantee. Improper repairs and incorrect installaon
or operaon shall invalidate the guarantee immediately.
12. If the heater was installed inappropriately or was connected unhomo-
geneously with the local electrical supply cable, high transfer resistances
may occur, which lead to overheang of the device. For the heang system
and many custom applicaons the heaters were equipped with a NTC
tempe rature control and an addional latching temperature limiter.
Ordinarily possible overhaeng due to inappropriate installaon is protec-
ted by the NTC temperature control and the latching temperature limiter.
If overheang of a carbon heang element occur due to interlinkage of
mounng and installaon mistakes, the carbon laments inside of the
quarz tubes will fuse and safely disconnect the current ow. Even aer a
mechanical break of the quarz tubes, the carbon heang spirals will not
work any longer. Besides the n front screen of the SPOT heaters and the
glass ceramic, high temperature resistant front screen of the VISION hea-
ters provide best pro tecon of the installed carbon heang elements.
Funconal descripon of the NTC temperature control: If the system
temperature of the electronical control exceeds 217.4 °F, the upper hea-
ng element will shut o temporary by default to avoid overhaeng of
the electronical parts. Aer a short me the heang element will switch
on automacally again. The self-controlled shut o of the heater will take
place only, if the heat dissipaon inside the device is inappropriate, if
the heat radiaon is interfered or if the ambience temperetaure is way
too high. Apart from that the NTC temperature control supports energy
sangs, if the ambient tempe ratures are too high and the highest heang
level of the heang unit is not necessary.
Funconal descripon of the latching temperature limiter: If the NTC
