If used, peel the backing from the double sided tape that was fixed
into the 50mm gap at the edge of the room.
Starting from the point furthest from the connection box, run the cold tails from each element along the room perimeter,
fixing them to the exposed double sided tape or if tape is not used, lay them carefully in the gap.
DO NOT
run the cold tails under the heating elements
Below each of the “cold tail” joints form a cut out in the foam un-
derlay to allow the plastic cover of the joint and the cold tail itself
to lay within the underlay. Fig. 9
The cut out for the cold tail should extend to the 50mm gap at the
edge of the room.
If you have installed more than one layer of foam underlay, only
form the cut-outs in the top layer.

Once the cold tails are in position a resistance test needs to be per-
formed on each individual element for a second time. The desired
resistance readings for each element are listed on the enclosed room
test data sheet.
Record the actual reading in the box provided on the data sheet.
This is a requirement of the guarantee and MUST be performed
at this stage.
The data sheet needs to be retained on site with the
heating system.
Note. The cold cables are double insulated, a coloured outer
and a clear inner.

The cold tails can now be joined in parallel at the junction box
using the 8-way electrical connectors provided.
The junction box should be a double gang blank fronted box of a
minimum 25mm depth. Fig. 11
The paralleled cold tails should be routed to the junction box and
connected to a suitably sized supply cable from the thermostat.
See Fig. 2 Page 3
