2 For your safety
General
Every person working with the Condair EL2 must have read and understood the present installation
andoperatinginstructionsbeforecarryingoutanywork.
Knowingandunderstanding thecontentsof the installationand operating instructionsisa basic
requirementforprotectingthepersonnelagainstanykindofdanger,topreventfaultyoperation,and
tooperatetheunitsafelyandcorrectly.
All ideograms, signs and markings applied to the unit must be observed and kept in readable
state.
Qualicationofpersonnel
All actions described in the present Installation and operating instructions (installation, operation,
maintenance,etc.)mustbecarriedoutonlybywelltrainedandsufcientlyqualiedpersonnel
authorised by the owner.
Forsafetyandwarrantyreasonsanyactionbeyondthescopeofthismanualsmustbecarriedout
onlybyqualiedpersonnelauthorisedbythemanufacturer.
ItisassumedthatallpersonsworkingwiththeCondairEL2arefamiliarandcomplywiththeappro-
priateregulationsonworksafetyandthepreventionofaccidents.
Intended use
ThesteamhumidierCondairEL2isintendedexclusivelyforairhumidicationviaasteamdis-
tributororafanunitapprovedbythemanufacturerwithinthespeciedoperatingconditions
(seechapter10“Productspecications”).Anyothertypeofapplicationwithouttheexpresswritten
consentofthemanufacturerisconsideredasnotconformingwiththeintendedpurposeandmay
lead to the Condair EL2 becoming dangerous.
Operationoftheequipmentintheintendedmannerrequiresthat all the information in these in-
structions is observed (in particular the safety instructions).

Danger that may arise from the unit
DANGER! Danger of electric hazard!
One may get in touch with live parts when the unit is open. Touching live parts may cause
severe injury or danger to life.
Prevention: Before carrying out any work set the Condair EL2 out of operation as described
in chapter 6.3 (switch off the unit, disconnect it from the mains and stop the water supply)
and secure the unit against inadvertent power-up.
WARNING! Danger of burning!
The Condair EL2 produces steam. When producing steam, the steam cylinder inside the
humidiergetsveryhot(upto100°C).Iftheunitisopenedimmediatelyafterhavingpro-
duced steam there is danger of burning when touching the steam cylinder.
Prevention: Before carrying out any work set the Condair EL2 out of operation as described
in chapter 6.5, then wait until the steam cylinder hascooleddownsufcientlythusprevent-
ing danger of burning.
Behaviour in case of danger
Ifitissuspectedthatsafe operation is no longer possible, then the Condair EL2 should immedi-
ately be shut down and secured against accidental power-up according to chapter 6.5. This
canbethecaseunderthefollowingcircumstances:
– iftheCondairEL2oritsmainscableisdamaged
– iftheCondairEL2isnolongeroperatingcorrectly
– ifconnectionsand/orpipingarenotsealed
AllpersonsworkingwiththeCondairEL2mustreportanyalterationstotheunitthatmayaffectsafety
to the owner without delay.
Prohibitedmodicationstotheunit
NomodicationsmustbeundertakenontheCondairEL2withouttheexpresswrittenconsentof
themanufacturer.
Forthereplacementofdefectivecomponentsuseexclusivelyoriginal accessories and spare parts
availablefromyourCondairsupplier.

3.4 Functional description
The steam humidier Condair EL2 is a pressureless steam generator that utilizes an electrode
heating. ThesteamhumidierCondairEL2isdesignedforairhumidicationviaasteamdistributor
(steamdistributionpipe,fanunitorsteamdistributionsystemOptiSorp).
Steam generation
Any time steam is requested, the electrodes are supplied with voltage via main contactor. Simultane-
ously,theinletvalveopensandwaterentersthesteamcylinderfromthebottomviawatercupand
supplyline.Assoonastheelectrodescomeincontactwiththewater,currentbeginstoowbetween
theelectrodes, eventually heatingand evaporatingthewater.Themore theelectrodesurface is
exposed to water, the higher is the current consumption and thus the steam capacity.
Uponreaching therequestedsteamcapacity,theinletvalvecloses.Ifthe steamgeneration de-
creasesbelowacertainpercentageoftherequiredcapacity,duetoloweringofthewaterlevel(e.g.
becauseoftheevaporationprocessordrainage),theinletvalveopensuntiltherequiredcapacity
is available again.
Iftherequiredsteamcapacityislowerthantheactualoutput,theinletvalveiscloseduntilthedesired
capacityisachievedbyloweringofthewaterlevel(evaporationprocess).
Level monitoring
A sensor provided in the steam cylinder cover detects when the water level gets too high. The mo-
ment the sensor comes in contact with water, the inlet valve closes.
Drainage
Asaresultoftheevaporationprocess,theconductivityofthewaterincreasesduetoanescalating
mineralconcentration.Eventually,aninadmissiblyhighcurrentconsumptionwouldtakeplaceifthis
concentrationprocesswere permittedtocontinue.To preventthisconcentrationfromreachinga
value,unsuitablyhighfortheoperation,acertainamountofwaterisperiodicallydrainedfromthe
cylinderandreplacedbyfreshwater.
Control
Thesteamproductioncanbecontrolledwithanexternalcontinuouscontroller0-10V(continuous
control)orwithanexternalhumidistat(On/Offcontrol).

4.1 Selecting the unit version
Themaximumrequiredsteamcapacitymustbecalculatedbasedononeofthefollowingformulas:
 V•ρ 
mD=  •(x2- x1)
1000
or
V
mD=  •(x2- x1)
 1000•ε
mD: maximumsteamdemandinkg/h
V: volumeofsupplyairportionperhourinm3/h(forindirectroomhumidication)orroomvolume
tobehumidiedperhourinm3/h(fordirectroomhumidication)
ρ: specicgravityofairinkg/m3

x2: desiredabsoluteroomairhumiditying/kg
x1: minimumabsolutesupplyairhumidityin g/kg
Thevaluesforρ,ε,x2and x1canbegatheredfromtheh,x-diagram or the Carrier-Diagramfor
moist air respectively.
Important notes:
– Therequiredmaximumsteamcapacitydependsonthespecicapplicationandtheinstallation.
Thecalculatedsteamcapacitybasedontheaboveformulas,theh,xdiagramandtheconditionof
theairtobehumidieddoesnotconsideranysteamloss(e.g.duetocondensationinthesteam
hosesandthesteamdistributors),anyheatlossoftheunitaswellasanyabsorptionorrelease
ofhumidityofmaterialslocatedintheroombeinghumidied.
In addition, the calculated steam capacity does not consider any losses caused by the draining
ratedependingonthewaterqualityaswellasanylossesoccurifthesteamhumidierisoperated
onamainscircuitwithagroundfaultcircuitinterrupter.
Thetotalamountoflossesdependsontheentiresystemandmustbetakenintoconsideration
whencalculatingtherequiredsteamcapacity.Ifyouhaveanyquestionsregardingthecalculation
ofthesteamcapacitypleasecontactyourCondairsupplier.

4.3 Selecting the control system
The various control systems
– System 1: Room humidity control
System1issuitedfordirectroomhumidication and air conditioning systems with mainly
recirculated air.Thehumiditysensororhumidistatrespectivelyispreferablylocatedintheroom
itselforintheexhaustairduct.

PIEExternal continuous controller
 (e.g.PIcontroller)
Y inputsignalfromA1
– System 2: Room humidity control with continuous limitation of the supply air humidity
System2issuitedforairconditioningsystemswithalarge portion of supply air, low supply air
temperature, post-humidication, or variableairowvolume.Ifthesupplyairhumidityexceeds
thepresetvalue,thecontinuouslimitationiseffectedpriortotheroomhumiditycontrol.
Thehumiditysensor(A1)ispreferablylocatedintheexhaustairductorintheroomitself.The
humiditysensor(A2)forthelimitationofthesupplyairhumidityislocatedinthesupplyairduct
afterthesteamdistributionpipe.Thiscontrolsystemrequiresacontinuouscontrollerwiththe
option to connect a second humidity sensor.
Attention! Thecontinuouslimitationofthesupplyairhumidityisnosubstituteforthesafetyhumi-
distat.
