11. The power cable or buried cable with omnipolar switch may only be replaced by a professi-
onal specialist electrical company enlisted or approved by the manufacturer. Heating elements,
other components or parts of the housing may only be replaced by a service organisation
enlisted by the manufacturer.
If you yourself or someone enlisted by you carries out repairs, they will not be covered by the
AU
guarantee. Improper repairs and incorrect installation or operation shall invalidate the guaran-
tee immediately.
12. If the heater was installed inappropriately or was connected unhomogeneously with the
local electrical supply cable, high transfer resistances may occur, which lead to overheating of
the device. For the heating system and many custom applications the heaters were equipped
with a NTC temperature control and an additional latching temperature limiter.
Ordinarily possible over heating due to inappropriate installation is protected by the NTC tempe-
rature control and the latching temperature limiter. If overheating of a carbon heating element
occur due to interlinkage of mounting and installation mistakes, the carbon filaments inside of
the quarz tubes will fuse and safely disconnect the current flow. Even after a mechanical break
of the quarz tubes, the carbon heating spirals will not work any longer. Besides the fin front
screen of the SPOT heaters and the glass ceramic, high temperature resistant front screen of
the VISION heaters provide best protection of the installed carbon heating elements.
functional description of the ntC temperature control: If the system temperature of the elect-
ronical control exceeds 103°C, the upper heating element will shut off temporary by default to
avoid over heating of the electronical parts. After a short time the heating element will switch on
automatically again. The self-controlled shut off of the heater will take place only, if the heat dis-
sipation inside the device is inappropriate, if the heat radiation is interfered or if the ambience
temperetaure is way too high. Apart from that the NTC temperature control supports energy
safings, if the ambient temperatures are too high and the highest heating level of the heating
unit is not necessary.
functional description of the latching temperature limiter: If the NTC temperature control is not
working against expectations, the latching temperature limiter will shut down the lower heating
element permanently (two red lights are flashing on the front of the device), until the heater is
shut off totally by hand. After cooling down (warm to the touch) and fixing the inappropriate heat
dissipation inside the device and/or the interferred heat radiation the heater can be switched
on again (the two red light on the front stopped flashing). If the lower heating element shuts
down once more (or if the two red lights continue flashing), a system malfunction or a heat
dissipation inside the device or an interference of the heat radiation or an error in the electrical
installation may be the reason. If a system malfunction inside the device causes the shut down,
the heater must be repaired by a professional technician; please contact your dealer imme-
diately. If a wrong cable connection causes the shut down, this has to be checked and fixed
through a professional electrician on the spot.
Installation and connecting regulations with tested and approved luster terminals are part of
the delivered equipment.
13. The radiant heater must not be installed directly below a power source/socket. The sides of
