Electrical Requirements
Before installing the eFlex you should make allowance for the electrical connections.
The eFlex system requires a mains voltage 230/240V and must be connected in
accordancewiththecurrentIEEregulationsandbuildingregulationspart‘P’approved
document.
For areas up to3450Wpower connection can be provided through a 13A switched
spuroutlet/combinedRCDspuroutlet.Forlargerareasadedicatedcircuitshouldbe
installed from the local consumer unit.
Conrm your thermostat is suitable to switch the appropriate electrical
load e.g. 16A thermostat is suitable to switch up to 3450W total load.
If you are required to switch greater electrical load than 16A a suitably sized
thermostat or electrical contactor MUST BE INSTALLED. Please consult our
Help Line if in doubt 08714 740 818.
WerecommendthatalleFlexsystemsareprotectedbya30maRCDearthtripeither
attheconsumerunitorbyacombinedRCDspuroutlet.
Wheninstallinginabathroomorotherwetareasthethermostatmustbelocated
outside Zone 2 (600mm from any wet appliance e.g. shower sink etc) or outside of the
wet area ideally on the opposite face of the wall.The eFlex must be earth bonded in
accordancewiththecurrentIEEregulations.
Important. When designing your electrical installation you should always
consult an electrician concerning your requirements.
Please follow these instructions carefully. If you require assistance prior to
or during your installation please call our helpline on 08714 740 818

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 oor 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 oor should now be prepared ready for the eFlex installation. All loose particles
should be removed and the oor thoroughly cleaned and treated with any proprietary
sealants as normally required.
Ifyourexistingoorhasabitumenorasphaltsurfaceitmusteitherberemovedor
covered with a thin exible 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exibletube,the
exible tube must be situated in-between two cable runs (see step 6).The oor
sensing probe is installed into the exible tube to monitor the oor temperature and
mayneedtobereplacedifthesensorfails.Ensurethetubeisinstalledtoalloweasy

Ensure your eFlex is correctly sized before you unpack the product.
Call 08714 740 818 with any questions.
Step 4

Step 6
Once the eFlex cold tail (power cable) and thermostat oor 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 oor area is covered. All heating cable must be used, any excess heating cable must
bereconguredintotheoorareabyadjusting yourcablespacing.Ensureallheating
cables are evenly spaced across the oor area.
• Do not cut any surplus heating cable.
• Do not leave any excess heating cable spooled or coiled in the oor area.
• Ensure all heating cable is used and spaced evenly across the oor.

Cable Spacing and Layout Instructions
It is important when calculating your eFlex spacing to accurately draw your
room area as this will help to save time and ensure a smooth installation.
1. Drawyourtotalroomareaincludingallxedfurnituresuchaskitchenunits,toilets
 andsinkareas.Markyourdrawingwithallrelevantdimensions.
2. Calculate the total oor area of your room.
3.
Calculate the area taken by all the oor obstructions.
4. Calculate the free oor area by subtracting the border area from the total area.
5. Calculate the watts per m² of your installation by dividing the rated power of your
eFlex cable by the free oor area. For example, if you have 3.6m² of free floor and you
havea600Wheatingcable:
600W÷3.6m²=167W/m²
6. Using the calculated watts per m² of your room refer to the lookup table below for
an indication of the required cable spacing to ensure even cable spacing across the
floor and therefore an even heat.

indicate one full space, the thin black lines between the coloured spacing indicate a

Warranty Validation
To validate your 15 year online warranty registration you must perform the insulation resistance
test, the heating cable resistance test, and the sensor resistance test three times during the
installation process.
1. Before you lay the eFlex.
2. After you have laid your eFlex and before you cover your eFlex.
3. After your nished oor has been laid.
This information must then be recorded on your commissioning record (enclosed within the box).
Floor Construction Examples
The eFlex is a loose laid cable which can be installed beneath most ceramic, porcelain/slate and natural stone tiles.
Whenusinglaminate,engineeredtimberorvinyloorsaexibleselflevellingcompoundshouldbeused.
Heating Cable Resistance Test
This test is carried out to prove continuity of the heating
element. A low resistance ohm meter should be used
(ieMultimeteronohmsetting),connectyourmeteron
to the black and blue mains lead and conrm resistance
value matches that quoted on your specication label
ontheeFlexColdLeadjoint.
Floor Cable Resistance Test
SeeHeatingCableResistanceTestandrepeatwithoor
sensor cable.
Insulation Resistance Test
This test is performed to measure the insulation
resistance between conductors and ensures the cable
insulation is not damaged. A low resistance reading
indicates a damaged cable and must be repaired or
replaced.
The insulation resistance tester should be connected
between the conductors (blue and black cables)
and the earth cable.The meter should
record a high
resistancevaluee.g.above100Megohms.
