Step 1
Draw a layout of your room including all obstacles e.g. Drain covers, toilets, sinks etc, then determine the required floor area to be heated.

Decide a suitable position for the thermostat (start point) then calculate your eCable spacing and layout.

Note
Ensure your eCable is correctly sized before you unpack the product.

Step 2
The floor should now be prepared ready for the eCable installation. All loose particles should be removed and the floor thoroughly cleaned and treated with any proprietary sealants as normally required.

If your existing floor has a bitumen or asphalt surface it must either be removed or covered with a thin flexible self levelling compound, sand cement mix or foil faced insulation panels. If you are installing foil faced insulation panels do so in accordance with the manufacturers instructions.

Note
Ensure all joints are properly taped and sealed to prevent the eCable from slipping in-between insulation panels.

Step 3
Directly below the electrical connection point install a 10mm flexible tube the flexible tube must be situated in-between two cable runs (see step 6). The floor sensing probe is installed into the flexible tube to monitor the floor temperature and may need to be replaced if the sensor fails. Ensure the tube is installed to allow easy replacement of the sensor probe.

The flexible tube in the floor should be sealed to prevent sand/cement mix or self levelling compound entering the tube. Secure the flexible tube in position with a section of fixing strip or robust utility tape.

Step 4
The fixing strip should then be anchored to the floor running perpendicular to your proposed heating cable layout and spaced evenly every 750mm.

The fixing strip fastening will vary depending on your floor base.

» Fix on to a concrete slab use masonry nails.
» Fix onto foil faced insulation panels use a robust utility tape.

Step 5
Perform the following tests: insulation resistance test, a heating cable resistance test and a floor sensor resistance test, record your findings in the test & commission form.

Remove the securing tape from your eCable roll and position at the start of your eCable plan with cold tail (power cable) at the electrical back box. Ensure the separate thermostat floor sensor cable is inserted in to the pre-installed 10mm flexible tube and returned to the low level electrical back box. The cold tail joint must be positioned in the floor area.

Step 6
Once the eCable cold tail (power cable) and thermostat floor sensor probe have been positioned you can now start to lay your eCable. Following your previously drawn eCable layout and spacing, continue to lay and secure your eCable on to the pre-installed fixing strip. Continue laying cable until total floor area is covered. All heating cable must be used, any excess heating cable must be reconfigured into the floor area by adjusting your cable spacing. Ensure all heating cables are evenly spaced across the floor area.

» Do not cut any surplus heating cable.
» Do not leave any excess heating cable spooled or coiled in the floor area.
» Ensure all heating cable is used and spaced evenly across the floor.

Step 7
Now that all your heating cable is correctly laid into your floor area you can begin to lay your floor screed. Ensure your floor screed is laid in accordance with your local building control requirements and take care not to damage your eCable product.

» Take care not to damage the heating cable.
» Do not disturb the cables from their pre-placed spacing.

Always allow 6-8 weeks for complete curing of your floor screed before switching your system on.
