13. 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 overhaeting due to inappropriate installation is protected by the NTC
temperature control and the latching temperature limiter. If overheating of a carbon heating
element occur due to interlinkage of mounting and installation mistakes, the carbon la-
ments inside of the quarz tubes will fuse and safely disconnect the current ow. Even after
a mechanical break of the quarz tubes, the carbon heating 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 heaters provide best protection of the installed carbon
heating elements.
Functional description of the NTC temperature control: If the system temperature of the
electronical control exceeds 217.4 °F, the upper heating element will shut off temporary by
default to avoid overhaeting 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 dissipation inside the device is inappropriate, if the heat radiation is inter-
fered 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
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, until the heater is shut off totally by hand. After cooling down
(warm to the touch) and xing the inappropriate heat dissipation inside the device and/or the
interferred heat radiation the heater can be switched on again. If the lower heating element
shuts down once more, 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 immediately. If a wrong cable connec-
tion causes the shut down, this has to be checked and xed through a professional electrician
on the spot.
Installation and connecting regulations with tested and approved luster terminals are part of
the delivered equipment.
14. The radiant heater must not be installed directly below a power source/socket. The sides
of the unit must be at least 8.00 inch from the nearest power source. Sockets/power sources
must be freely accessible at all times and comply with the following specications: 220–240
V AC , 50/60 Hz, 16 A with 16 A fuse. No other loads may be connected to this power source.
15. The radiant heater must not be installed in close vicinity to bathtubes, showers or pools
nor in rooms where there is permanent high humidity. The distance to the bathtub or shower
