How To Install eFlex Cable
Follow the step by step instructions below to install your eFlex Cable system.

 |
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. Call 08714 740818 with any questions.

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.

Steps 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. |
 |
Steps 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. |
 |
Steps 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 heating cable spooled or coiled in the floor area.
• Ensure all heating cable is used and spaced evenly across the floor. |

Steps 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. |
|
Steps 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.
Note
After the finished floor covering has been laid perform the following tests:
- Insulation resistance test
- Heating cable resistance test
- Thermostat floor sensor resistance test
