Check the resistance of each element using a suitable
electrical testing device.
A basic multi-meter will be sufficient to test the elements
at this stage.
You can purchase a suitable test device from your un-
derfloor heating supplier or most DIY stores stock similar
products.
DO NOT
continue without first testing each element.
The desired resistance readings for each element are
listed on the enclosed room test data sheet. A sample of
the data sheet is shown in fig. 6. The reading should be
within the Design Resistance Reading Range e.g a
reading of 223
Ω
for the range circled in the example fig
6 is acceptable.
Note. The cold cables are double
Insulated, a coloured outer and a clear inner.

should be worn . Avoid foot traffic on the heating elements and cold tail joints.
Un-pack the heating elements for the room and check that you have all the elements detailed on the enclosed drawing &
room test data sheet.

Position the rolled up elements along the edge of the room Fig.7, as per the drawing supplied. When you are satisfied with
the position of the elements (ensuring that they will not overlap), roll out the heating elements Fig.8. The elements can be
laid either way up, however we recommend they are installed copper face down to aid recessing the cold tail connections
into the insulation underlay.
Adjust positioning to obtain the best floor coverage and lightly fix into position with self adhesive cloth tape (duct tape) to
avoid movement.
