Handling
Caremustbetakenwhentransporting,storingandinstallingtheequipment:
• Atleasttwopeopleshouldliftthecylindertopreventinjuries.
• Thecylindermustbestoredinadryareaandmustneverbesetdownhardduringhandling.
• Packagingshouldonlyberemovedattheinstallationlocation.
• Thecylindermustbeinstalledonalevelorwiththerequiredloadbearingcapability.Installation,
servicing, maintenance and repair must be carried out by a competent person.
• Allelectricalwiringmustbecarriedoutbyaqualiedelectricianandbeinstalledinaccordance
with current I.E.E Wiring Regulations.
• Alackofsafetydevicescanleadtopotentiallyfatalinjuries,allnecessarysafetydevicesmust
be installed correctly in the system. The use of an electric immersion may lead to the build up
of electrical potential in the water. This can in turn cause corrosion of the immersion. To prevent
this, ensure the immersion heater, and the hot and cold pipework are correctly bonded and
connected to the earth line.
• Ifplasticpipesareusedtheymustbeapprovedtemperatureresistantto95°Catapressureof
10bar.
Athermostaticmixershouldbeinstalledinthesystemtopreventtheriskofscalding.Ifthereare
leaks found in the system, shut o the cold water stop valve from the main supply and contact a
competent person immediately.
What Is Benchmark?
Benchmark places responsibilities on both manufacturers and installers. The purpose is to ensure
thatcustomersareprovidedwiththecorrectequipmentfortheirneeds,thatitisinstalled,commis-
sionedandservicedinaccordancewiththemanufacturer’sinstructionsbycompetentpersonsand
thatitmeetstherequirementsoftheappropriateBuildingRegulations.
TheBenchmarkChecklistcanbeusedtodemonstratecompliancewithBuildingRegulationsand
shouldbeprovidedtothecustomerforfuturereference.Installersarerequiredtocarryoutinstalla-
tion,commissioningandservicingworkinaccordancewiththeBenchmarkCodeofPracticewhich

Water Supply
The performance of any unvented system is only as good as the mains water supply available. To
this e ect the maximum possible water demand should be assessed, with the knowledge that the
mains supplies both hot and cold services simultaneously. The water heater itself operates at a
pressure of 3bar, controlled by the inlet control set, and is capable of delivering over 50 litres per minute.
Thehighqualityinletcontrolsethasbeendesignedtomakethemostofthelowratesavailable.
Thewatersupplyshouldbecheckedtoensureitcanmeettheserequirements.Ifnecessary,consult
thelocalwaterauthorityregardingthelikelypressureandowrateavailability.
Considerationshouldbegiventoupgradingexisting1⁄2”(15mm)coldmainspipeworktoalarger
sizeiftherecommendedminimumpressure/owrateisnotbeingachieved.JOULErecommend
that primary pipework used has a minimum diameter of 22mm to ensure low pressure loss.
Ahighstatic(noow)mainspressureisnoguaranteeofgoodowavailability.Ina
domestic installation 1.5bar and 25ltr/min should be regarded as the minimum. The
maximum mains pressure that the inlet control set can cope with is 10bar.
Change Of Water Supply
Thechangingoralternatingfromonewatersupplytoanothercanhaveadetrimentaleectonthe
operation and/or life expectation of the water heater storage cylinder, pressure temperature relief
valve and heating unit.
Where there is a changeover from one water supply to another, e.g. a rainwater tank supply, bore
water supply, desalinated water supply, public reticulated water supply or water brought in from
another supply, then water chemistry information should be sought from the supplier or it should
betestedtoensurethewatersupplymeetstherequirementsgivenintheseguidelinesfortheJoule
warranty to apply.
Water Chemistry
This water heater must be installed in accordance with this advice to be covered by the Joule war-
ranty. This water heater is manufactured to suit the water conditions of most public reticulated water
supplies.However,therearesomeknownwaterchemistrieswhichcanhavedetrimentaleectson
the water heater and its operation and/or life expectancy. If you are unsure of your water chemistry,
you may be able to obtain information from your local water supply authority. We recommend not to
usewatersoftener,howeverifitisusedthewaterisrequiredtobekeptatpotablestandards.This
water heater should only be connected to a water supply which complies with these guidelines for
the JOULE warranty to apply.

Water Chemistry Levels Aecting Warranty
The JOULE warranty of this water heater will not cover resultant faults on components including
the storage cylinder where water stored in the storage cylinder exceeds at any time any of the fol-
lowing levels:
Components Maximum Permitted Levels
TotalDissolvedSolids 600 mg/litre
TotalHardness 200 mg/litre
Chloride 300 mg/litre
Magnesium 10 mg/litre
Calcium 20 mg/litre
Soldium 150 mg/litre
Iron 1 mg/litre
MaximumpH 9.5
MinimumpH 6.5
Total Dissolved Solids (TDS)
Some water analysis reports may state the conductivity of the water rather than the level of total dis-
solvedsolids.Conductivity,measuredinmicrosiemenspercentimetre(μS/cm),isdirectlyproportional
totheTDScontentofthewater.TDS,inmg/L,isapproximately70%oftheconductivityinμS/cm.
The JOULE warranty will not cover resultant faults to the storage cylinder if this water heater is con-
nectedatanytimetoawatersupplywheretheTDScontentofthewaterexceeds600mg/L.16In
locationswhereTDSapproaches600mg/L,e.g.duetosediment,westronglyrecommendttingan
appropriateltertoensurewaterenteringorinthewaterheaterdoesnotexceedthislevelatany
time i.e. due to sediment build up.

General Requirements
Wellmaster Cylinders
Only JOULE Wellmaster cylinders may be installed on a well, private water scheme or any water
source that does not come from the public mains.
Watersuppliedtothecylindermustconformtothewaterchemistrytableonthepreviouspage.A
descaleronthecoldwaterfeedmaybeusedifrequired.
If any of the water parameters are higher than set out in the table including total
hardness regardless of wheter or not it is fed from a main water connection a Joule
Wellmaster cylinder must be used.
IfanyofthewaterparametersarehigherthansetoutinthetableincludingTotalHardnessregardless
of whether or not it is fed from a main water connection a JOULE Wellmaster cylinder must be used.
Siting The Unit
This unit can supply outlets above it or at some distance from it but any outlets above the unit will
reduce the available outlet pressure by 0.1 bar for every 1m of height derence. The maximum
lengthofthe“deadleg”shouldbeasstatedintheWaterSupply(WaterFittings)Regulations1999
G18.7,inparticulartotheareaofmostfrequentuse.
Particular attention is needed if sitting in a garage or outbuilding as the unit should be protected
fromfrost.Allexposedpipeworkmustbeinsulated.Theunitmustbeinstalledupright on a at base
capable of supporting its weight when full (please see the tech- nical speci cation section for weights).
Sucientaccesstoallowmaintenanceofthevalvesshouldbeconsidered.Inadditiontheimmer-
sion heaters are 400mm in length and this distance should be considered to allow withdrawal for
servicingifrequired.Thedischargepipeworkfromthesafetyvalvesshouldfallcontinuouslyand
terminate safely.
Negative pressure may form in cylinders installed very high in a building. To counteract this, an anti-
vacuum valve can be installed to prevent damage to the cylinder. The anti-vacuum valve ensures
thatpressurecompensationasaresultofairowingintothecylinder.
Connecting To The Cylinder
Allofthepipeworkconnectionsonthecylinderarefemalethreaded.Uponlling/commissioning,
ensure all connections are completely watertight.
Nocontrolorisolationvalveshouldbettedbetweentheexpansionreliefvalveandthe
storage cylinder. The relief valve connections should not be used for any other purpose.

Cyclone Direct / Indirect Installation Guide

Cold Mains Pipework
Run the cold main through the building to the place where is to be installed. Take care not to run the
coldpipenearhotwaterorheatingpipeworksothattheheatpick-upisminimized.Identifythecold
watersupplypipeandtanisolatingvalve(notsupplied).A22mmBS1010stopcockcantypically
beusedbuta22mmquarterturnfullborevalvewouldbebetterasitdoesnotrestricttheowas
much.Donotuse“screwdriverslot”orsimilarvalves.
Make the connection to the cold feed of the cylinder and incorporate a drain valve. Position the
inlet control just above the Temperature & Pressure Relief Valve (TPRV) mounted on the side of the
cylinder. This ensures that the cylinder does not have to be drained down in order to service the inlet
controlset.Ensurethatthearrowpointsinthedirectionofthewaterow.Selectasuitableposition
for the expansion vessel. Mount it to the wall using the bracket provided.
Balanced Cold Connection
If there are to be showers, bidets or monobloc taps in the installation then a balanced cold supply
is necessary. There is a 22mm balanced connection on the inlet control set.
Fitting The Inlet Control Group
Excess pressure can lead to the cylinder bursting. The inlet control set supplied has an expansion
relief valve with a 15mm connection to allow it to be connected to the tundish. Make sure that there
is su cient space for future maintenance and also for connection of the discharge pipe for the ex-
pansion relief valve.
It is essential that this connection is not covered or closed. The hot water expansion vessel should
behardxedintopipeworkandinsulated.
Hot Water Pipework
Runtherstpartofthehotwaterdistributionpipeworkin22mm.Thiscanbereducedto15mm
and10mmasappropriateforthetypeoftapetc.Youraimshouldbetoreducethevolumeofthe
hotdraw-opipeworktoapracticalminimumsothatthetimetakenforthehotwaterisasquick
as possible.
Donotusemonoblocmixertaporshowersifthebalancedcoldconnectionisnotprovided.Outlets
of this type can back pressurise the unit and result in discharge.
Expansion Vessel
The expansion vessel receives the increased water volume when expansion takes place as the
system heats up and it maintains a positive pressure in the system. The expansion vessel contains
a exible diaphragm, which is initially charged on one side with nitrogen, but can be topped up with
airwhenrequired.
Select a suitable position for the expansion vessel. Mount it to the wall using the bracket provided
andhardxintopipeworkandinsulate.Ensurethatthetopofthevesselisaccessibleforservicing.
The pipe connecting the expansion vessel to the system should have a diameter of not less than
15mm and must not contain any restrictions.

www.jouleuk.co.uk | www.joule.ie
12
General Requirements
Priortoconnectingtheexpansionvesseltothesystemthepipeworkshouldbeushedandtested.
When the vessel is connected the system should be pressurised when cold. If the initial system
water pressure is too high, the diaphragm will be displaced too far into the vessel. This will leave the
vessel unable to accommodate the volume of expansion water. The result of this is an increase in
system pressure and the safety valve will lift.
Primary Coil Connections
Connecttheprimaryconnections (Indirectonly).Theprimary circuitmustbepositivelypumped.
Eitherprimaryconnectionmaybeusedastheprimaryow.Reheattimesareidenticaleitherway.
The primary circuit can be open vented or sealed, with up to a maximum pressure of 3.5 bar. If you
sealtheprimarycircuitanadditionalexpansionvesselandsafetyvalveisrequired.
TheboilermaybeGas,ElectricorOilbutmustbeundereectivethermostaticcontrol.Uncontrolled
heatsourcessuchassomeAGA’s,backboilers,solidfuelstoves,etc.arenot suitable. Please con-
tactourTechnicaldepartmentforguidance.Connectthetwoportzonevalve(indirectonly)intothe
primaryowpipework.Thedirectionofowarrowshouldbetowardstheprimaryowconnection.
Installing The Two Port Motorised Valve
The function of the Two Port Motorised Valve prevents the cylinder from overheating. It can be in-
stalledoneitherhorizontalorverticalpipework.
Ifitismountedontohorizontalpipeworkthevalveheadmustfaceupwards.Thedirectionofowis
marked on the body of the valve with arrows.
Thermostatic Mixer
WheninstallingasolarsystemwithanunventedJOULECyclonetwincoilcylinder,athermostatic
mixing valve should be installed. Its function is to act as an anti scald protection. The thermostatic
mixeristobesettoatemperatureofbetween30°Cand60°Candissuppliedbytheinstaller.
Secondary Circulation
Onlargerinstallationslongpiperunstodraw-opointscancausesignicantvolumesofwatertobe
drawnobeforeanacceptabletemperaturecanbereached.Secondarypumpedcirculationusing
astainlesssteelorabronzepump,andcombinedwitheectivetimeandtemperaturecontrolscan
overcomethisproblem.Wheresecondaryreturncirculationisrequiredthepipeworkshouldberun
in15mmpipe.AsuitableWRASapprovedstainlesssteelorbronzecirculationpumpmustbeused.
Acheckvalvemustalsobeinstalledtopreventbackow.
On large secondary circulation systems it may be necessary to incorporate an extra expansion
vessel into the circuit to accommodate the increased system water volume. Secondary circulation
shouldbeavoidedon Directelectricallyheatedunits being used ono-peakelectricitytaris.It
should be noted that the use of a secondary circulation circuit can increase running costs as there
willbecirculationpipelosses.Highlevelsofinsulationonsecondarypipeworkarerequiredtokeep
energy losses to a minimum.

Dead Legs
Thelengthofhotwaterdrawototapsandotheroutletsshouldbekepttoaminimumtoreducethe
amountofcoldwaterdrawnobeforethehotwaterarrives.Themaximumrecommendeddeadleg
lengthsareshowningure2.b.Wherethereismorethanonesizeofpipeonadeadleg,theequiva-
lentlengthandsize should be estimated.Wherethe dead leg lengthexceedstherecommended
maximum, secondary circulation should be installed. It should be controlled by a time switch and
incorporateamotorizedvalvethatcanpreventgravitycirculationinthecircuit.

System Noise
Noise in pipework may occur as a result of expansion of pipework over joists or where the pipe has
beenlefttouchingotherpipesorapartofthebuildingstructure.Caremustbetakentoensurethat
the pipework is correctly bracketed, is not in tension or compression, and does not carry the weight
of components such as a circulation pump.
Setting The Hot Water Temperature
The hot water temperature is set on the dual thermostat by the competent person during the instal-
lation.Thedualthermostatshouldbesetto60°C.Ifyouareheatingwaterinthecylinderforthe
rsttime,orthetimecontrolsfortheDHWzonehavebeenoforaprolongedperiodoftime,the
cylinder may take additional time to heat up.
Inappropriate adjustments can lead to the damages in the system. In any changes
are made to the cylinder, the controls, the water and power supply lines or the expan-
sion relief components there is a risk of steam escaping or rupture to the system.
