4. Guidelines for installation
Selection of the adequate positioning of the
sensor is a key factor to proper operation of
the heating system. It influences directly the
effectiveness of the protection, as well as the
future costs of operation.
ETOG-56T sensors are to be installed within the
heated area, in an unsheltered position especially
vulnerable to longest expositions to moisture and
low temperatures. This position should also be
exposed to direct rain or snowfall.
In case of heating only the driving tracks, it is
recommended to install the sensor at the edge
of the tracks to be protected. It is possible thus
to avoid snow deposition on the tracks by
vehicles’ wheels. Small amount of snow falling
from the tyres does not constitute any danger
to safe driving, still can cause unnecessary
switching on of the heating system.
Installation should commence with mounting
of the ETOK-T type protection tube, included
in the set. Lead the protective conduit with the
so called “draw wire” to the planned position
of the sensor, and seal it (after the surface
works have finished, the conduit will help
feeding the sensor’s wire).
