eFlex and Floor Sensor

1st Step 2nd Step

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

Installation Instructions

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

replacement of the sensor probe.

The exible tube in the oor

should be sealed to prevent tile adhesive or self levelling

compound entering t

hetube.Securetheexibletubeinpositionwithasectionof

robust utility tape.

Ensure your eFlex is correctly sized before you unpack the product.

Call 08714 740 818 with any questions.

Step 4

Lay the eFix double-sided adhesive tape across the oor, 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

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

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.

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.

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.
