•Fit the unit onto a flat piece of wall, well away from any potential splashes of water or spray.
•Position the unit either upright orlengthways (diagram 1), whichever is most convenient for
plumbing and wiring.
Remember to keep the lengths of hot water pipe to a minimum in order to save energy.
•If the unit is to supply a basin, you can fit it either above or below the basin.
HOW TO INSTALL YOUR IL095

4
Deciding the wiringroute
•You have a choice of whether to feed the electric cable
through the side or through the back of the unit.
•If it going through the side of the unit, cut out the
plastic lug to expose the grommet (diagram 2).
•If is going through the back of the unit, cut through the
grommet on the backplate with a sharp knife (Take Care!).
Make sure you do not remove the grommet from the backplate (diagram 3).
Feed the cable through the grommet before you fix the unit to the wall.
Fixing to the wall
•Undo the retaining nuts and take the front cover
off the unit. Hold the backplate in position against
the wall whilst you mark the four fixing holes.
•Drill the holes and fix the unit to the wall using the
four No.8 x 38mm wood screws supplied.
Plumbing the unit
WARNING: IF A NON RETURN VALVE IS FITTED IN THE INLET FEED TO THE UNIT,
THEN THE INSTALLATION SHOULD ALSO INCLUDE A 3.5 BAR PRESSURE
REDUCING VALVE AND A 6 BAR PRESSURE RELIEF (EXPANSION) VALVE

WARNING: ENSURE THAT THE MAINS WATER SUPPLY MEETS THE REQUIREMENTS
LISTED ON PAGE 3 BEFORE CONTINUING WITH INSTALLATION.
WARNING: BEFORE CONNECTING THE PIPE WORK TO THE IL095,
ENSURE THAT THE PIPE WORK IS FULLY FLUSHED OUT.
Fitting the pipes
•The unit should be connected directly to the main cold water supply.
•We recommend that you use Ø15mm copperor stainless steel pipe for the inlet and outlet
connections.
•Use PTFE tape formaking screw joints. Do not use a jointing compound.
•Remember to keep the hot water pipe runs as short as possible.
In some cases, it may be worth fitting a second unit.
•If the unit is to supply more than one basin outlet, the head should be the same at each outlet if
they are to be used at the same time.
If not, one outlet will take all the water.
•When the pipework has been plumbed in, flush it through with water before you connect the
unit, to remove any swarf or loose particles.
Connecting the unit to the pipes
•The inlet and outlet are clearly marked on the unit.
They each have a Ø15mm straight shank connections.
•The unit comes with a service valve (diagram 5) which should be fitted on the inlet of the unit.
The valve can be used to turn off the water supply to the unit if it needs servicing, or to reduce
the main supply flow if it is too high.
Fitting the attachments
•If the unit is to supply a shower, you will also need a “Dimplex Mixer Unit”.
Available in chrome/white finish and suitable for surface or concealed pipe entry (see page 9).
•If the unit is to supply a shower, and the shower handset can reachwater in a bath or basin, you
must fit a vacuum breaker to comply with Water By-laws.
Vacuum breakers are available from our salesoffice (see page 9).
Alternatively, use the hose-retaining feature built into the soapdish.
Because water can sometimes seep through, you should position the vacuum breaker where
dripping will not do any damage.
•If the unit is to supply a basin, we recommend that you use spray taps, which you can get from
your local stockist (not Dimplex supplied).

•A 40 amp 240V supply is required for the 9.5kW unit
•A 45 amp 240V supply is required for the 10.8kW unit
•A 50 amp 240V supply is required for the 12.0kW unit
9.5kW IL095 Wiring Conditions:
If the cable run is less than 10 metres and is surface run, 6mm² cable can be used.
A means for disconnection in all poles must be incorporated in the fixed wiring in accordance with
the wiring rules.
The isolating switch should be rated at: 40 amps or greater for the 9.5kW unit.
Wire the unit using a suitable Fuse/MCB: 40 amps Fuse/MCB for the 9.5kW unit.
12.0kW and 10.8kW IL095 Wiring Conditions:
This unit has been designed to accept 10mm² supply cable. Therefore, this is the size of cable that
should be used between the isolator switch and the unit, even if you decide to use 16mm² between
the fuse box and isolating switch. 10mm² supply cable is recommended for the 12.0kW, and for long
cable runs (greater than 10 metres) also for the 10.8kW unit.
The isolating switch should be rated at: 45 amps for the 10.8kW unit / 50 amps forthe 12.0kW unit.
Wire the unit using 10mm² cable and a suitable Fuse/MCB:
45 amps Fuse/MCB for the 10.8kW unit / 50 amps Fuse/MCB for the 12.0kW unit.
If the unit is fitted in a bathroom:
9.5kW and 10.8kW IL095: A standard 45 amp cord operated isolatorswitch is recommended.
12.0kW IL095: A pull cord isolator switch is not available for this model. A double pole 50 amp
isolator switchis required. This must be mounted out of reach ofthe shower cubicle or bath.
Connecting the unit to the mains
•Strip back the insulation on the LIVE (brown or red) and NEUTRAL (Blue or black) mains wires
about 8mm. Strip backany insulation on the EARTH (green/yellow or green) about 20mm.
•Feed the cable through the side or rear entry grommets, as appropriate.
The outer sheath of the cable must project through the grommet (diagram 6).
If the side entry is used, this will stop water getting into the unit.
•Connect the cables to the terminal block and earth stud (diagram 6).
•Make sure that the live and neutral terminal block screws are tightened securely (1Nm minimum)
•Make sure that the earth wire is wrapped around its terminal stud and into the saddle washer.
The nut should be tightened securely (2 Nm minimum).
WARNING: FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN
FAILURE OF THE TERMINAL BLOCK
•Check that the Power Selector Screw) on theflow switch is set to “HI” (diagram 7).
If it is set to “LO” only one heater element will operate.
•Fit the front cover and tighten the retaining nuts.

Ensuring the earth continuity
•If the unit is fitted in a bathroom, to conformwith the current BS.7671 (formally IEE regulations),
the units earth continuity conductor must be effectively connected to ALL exposed metal parts of
ALL other appliances in the room.
CHECKING FOR LEAKS
•Let the water run through the unit for a few seconds. Check that no pipe joints leak.
ADJUSTING THE SERVICE VALVE
Turn the service valve on, then:-
•If the unit is to supply a basin,
- turn on the hot watertap fully at the basin.
- adjust the service valve until the water comes out of the tap at the required temperature.
- check that the unit works correctly when the basin tap is closed and then opened again:
if not, adjust the service valve slightly.
•If the unit is to supply a shower,
- turn the hot water tap on the mixer unit fully on.
- turn the service valve anti-clockwise until the neon light goes out, then turn it back until the
neon just comes on.
-check the water temperature at the handset and, if necessary, turn the cold tap on and adjust
to get the desired shower temperature.
WARNING: IN ORDER TO MAINTAINTHE PERFORMANCE OF YOUR SHOWER,
YOU MUST CLEANTHE SHOWER HANDSET REGULARLY.
All water contains particles of lime-scale, which build up in the shower handset and unit reducing the
performance.
It is therefore important to clean the shower handset by regularly dipping it in a suitable descaling
solution. The frequency of this will depend on water hardness and experience.
Explain to the user that when the unit is used, the hot water tap should be turned fully
on so that the unit will operate correctly.

Water comes in through the inlet, via a flow switch.
The flow switch measures how much water ispassing through the unit.
If it detects more thanthe preset level of:-
2.7 litres/minute for the 9.5kW model and 3.3 litres/minute for the 10.8kW and 12.0kW models
The units heating elements are switched on. This is shown by the neon light glowing.
The water is heated instantly as it passes through the copper heat exchanger tube.
The temperature of the water coming out of the unit depends on:-
•The temperature of the mains water supply
•The water flow rate
•The power consumption of the unit
The temperature of the main supply can varyfrom 5°C in winter up to about 20°C in summer, with
an average ofabout 12°C. The charts below show the water temperature (°C) you can expect from
the unit, operating at 9.5/10.8/12.0Kw for the different flow rates (in litres/minute)
9.5kW IL095
Flow rate (l/m) 3.0 4.0 6.0
Summer temp °C _ 54° 43°
Winter temp °C 50° 39° 28°
10.8kW IL095
Flow rate (l/m) 4.0 5.0 6.0
Summer temp °C _ 51° 46°
Winter temp °C 44° 36° 31°
12.0kW IL095
Flow rate (l/m) 5.0 6.0 7.0
Summer temp °C 54° 49° 44°
Winter temp °C 39° 34° 30°
This means that with the 12.0kW unit you can shower at 39°C with a flow rate of 5 litres/minute in
the middle of winter.
The unit includes a dual thermal cut-out (diagram 10) which is attached to
the heat exchanger tube. It will switch off the heater elements if the water
flow is reduced too much and the temperature goes above a set limit.
The first stage cut-out is cyclic and will automatically reset as the water
temperature falls. The unit will then function normally again.
The second stage cut-out when triggered needs to be reset manually inside the unit.
This cut-out will only operate in exceptional circumstances (diagram 11)
The unit can supply more than one outlet – for example, a shower and a basin, ortwo basins – but
water fromthe unit will be shared between the outlets. This is particularly important if a unit supplies
a shower and a basin, as the basin should not be used while someone is using the shower.
HOW YOUR IL095 WORKS
On average
(12°C main water supply at 4 litres/minute)
an outlet temperature of 46°C will be achieved.
On average
(12°C main water supply at 5 litres/minute) an
outlet temperature of 43°C will be achieved.
On average
(12°C main water supply at 6 litres/minute) an
outlet temperature of 41°C will be achieved.
