12. If the heater was installed inappropriately or was connected unhomogeneously with the local elec-
trical 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 filaments inside of the quarz tubes will
fuse and safely disconnect the current flow. Even after a mechanical break of the quarz tubes, the car-
bon 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 electronical
control exceeds 217.4 °F, the upper heating element will shut off temporary by default to avoid over-
haeting 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 interfered or if the ambience temperetaure is way too
high. Apart from that the NTC temperature control supports energy safings, if the ambient temperatu-
res 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 wor-
king 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
fixing 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 mal-
function 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 immedi-
ately. 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 the
unit must be at least 7.87 inch from the nearest power source. Sockets/power sources must be freely
accessible at all times and comply with the following specifications: 220–240 V AC ~, 50/60 Hz, 16 A
with 16 A fuse. No other loads may be connected to this power source.
14. The radiant heater must must not be installed in rooms where there is high humidity (bathroom,
spa, pool etc.) in close vicinity to bathtubes, showers or pools. The distance to the bathtub or shower
must be at least 39.37 inch and the distance to the pool at least 78.74 inch. A person standing in the
bathtube, shower or pool should never reach the switch or controller of the heater. If the HEATSCOPE®
is installed in such an environment with high humidity, the switches or other operating components
must be positioned in such a way that they cannot be touched by persons who are in direct contact
with water. Bathroom heaters must not be operated with a separate automatic thermostat or timer.
When a radiant heater is installed in a bathroom, the CE standard requires that at least one heating
element visibly „glows" as soon as the unit is switched on.
