Installation

Follow the step by step instructions below to install your eFlex Cable.
 
Step 1
Draw a layout of your room including all obstacles e.g. toilet sink etc, then determine the required floor area to be heated. Decide a suitable position for the thermostat (start point) then sketch the proposed eMat layout to ensure the heated area is completely covered whilst using all of your eMat.

Note
Ensure your eFlex cable is correctly sized before you unpack the product.
Step 2
The floor should now be prepared ready for the eFlex 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 insulation panels.

When installing insulation panels ensure all joints are properly taped and
sealed to prevent the eFlex from slipping in-between any panels used.

Step 3
Directly below the electrical connection point install the 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 tile adhesive or self levelling compound entering the tube. Secure the flexible tube in position with a section of robust utility tape.

Step 4
Lay the eFix double-sided adhesive tape across the floor, perpendicular to your proposed heating cable layout, ensuring there is tape at either end of the cable loops and in between, spaced at a maximum of every 600mm. Then lay the eGauge measuring tape in line with the eFix 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 enclosed in the box.

Remove the securing tape from your eFlex roll and position at the start of your eFlex 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 eFlex cold tail (power cable) and thermostat floor sensor probe have been positioned you can now start to lay your heating cable. Following your previously drawn layout and spacing, continue to lay and secure your eFlex heating cable onto the double-sided adhesive tape using the eGauge for guidance. 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 cable spooled or coiled in the floor area.
» Ensure all heating cable is used and spaced evenly across the floor.

Step 7
Lay the eMesh onto the double sided tape to secure the heating cables. Further lengths of eMesh can be used to secure the heating cable between the double-sided tapes, if required.
Step 8
With the eFlex laid and secure, it can now be covered with either a flexible tile adhesive or flexible self levelling compound.

Ensuring there are no air pockets, carefully spread the flexible tile adhesive or self levelling compound until all heating cables are covered. You may tile directly over the eFlex, carefully applying your flexible tile adhesive with a notched trowel ensuring each tile is securely fixed and all cable areas are completely covered with flexible tile adhesive.
