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.
Heat the surfaces on which
braking will occur, e.g. before
a barrier or a magnetic card
reader.
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.

Thoroughly clean the substratum before

shortened or spliced.
Heat at least one
metre into the
covered area.
Heat the covered
