LAYOUT CONSIDERATIONS

Area to be heated
Determine the exact area to be heated, e.g. wheel tracks. Consider the following factors:
Do not run the heating cable
over expansion joints.
First make sure that the area to be heated
complies with the data in the design instructions.
Establish where the junction boxes are to be
installed and check that the connection leads are
long enough.
Heat the surfaces on which braking
will occur, e.g. before a barrier or a
magnetic card reader.
Covered area
Covered area
Lay the heating cable right up to
the drain-off gutter.
The length is 4 m.
Thoroughly clean the substratum before starting
to install the heating mat, as sharp objects can
damage the heating cable.
The EM4-CW-Cable must not be shortened or
spliced.
Heat at least one
metre into the
covered area.
Heat the covered area
of the entry, as incoming
vehicles can bring in
snow.
Heat the drain-
off gutter.
