Installation Step 4 and 5 – Lay out heating element and secure with fixing tape.
Gently unroll the power supply cable from the
spool. After 3 metres of black cable has been
removed, you will reach the point at which the
power supply cable joins the heating element
wire (which is of a different colour).
The join of the power supply cable and the
heating cable should be taped to the floor at
the start point (which is the first of the
chiselled channels).
Following the perimeter markings on the floor,
lay out the heating element wire, taping down
at each corner. The element wire should run
from the start point in a U shape to the
furthest corner from the start point.
Once the element wire has been laid out
around the perimeter, start laying out the
heater wire in parallel lines back and forth
across the main body of the area to be heated.
Using the spacing markings, tape down the
element to the floor with strips of the
adhesive tape (which has been supplied) over
the pre sprayed areas. The tape strips should
be about 25mm (1 inch) long.
You will also note a ½ way marker indicating
that you have used up ½ the length of the
heating element. Check the coverage of the
floor already completed to gauge your end
result.
Once the floor has been marked up, the element wire can be laid out.
