Installation Instructions
4
Step 1
Draw a layout of your room (see page 6) 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 refer to page 6 to
calculate your cable spacing and layout.
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 t
he tube. Secure the flexible tube in position with a section of
robust utility tape.
Ensure your eFlex is correctly sized before you unpack the product.

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.
