Danger that may arise from the unit
DANGER!
Danger of electrical shock!
The Condair CS is mains powered. 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CSoutofoperationasdescribedin
chapter5.5(switchofftheunit,disconnectitfromthemainsandstopthewatersupply)andsecure
theunitagainstinadvertentpower-up.
WARNING!
Hot water vapour - Danger of scalding!
The Condair CS produces hot water vapour. There is danger of scalding when getting in
touch with hot water vapour.
Prevention:Donotcarryoutanyworkonthesteamsystemduringoperation(steamlines,steam
distributor,etc.).IfthesteamsystemisleakysettheCondairCSimmediatelyoutofoperationas
describedinchapter5.5.Correctlysealthesteamsystembeforeputtingtheunitintooperationagain.
WARNING!
Danger of burning!
During operation the components of the steam system get very hot (up to 100 °C). There is
danger of burning when touching the hot components.
Prevention: BeforecarryingoutanyworkonthesteamsystemsettheCondairCSoutofoperation
asdescribedinchapter5.5,thenwaituntilthecomponentshavecooleddownsufcientlythus
preventing danger of burning.
Behaviour in case of danger
If it is suspected that safe operation is no longer possible,thentheCondairCSshouldimmediately
be shut down and secured against accidental power-up according to chapter 5.5. This can be
thecaseunderthefollowingcircumstances:
– iftheCondairCSisdamaged
– iftheCondairCSisnolongeroperatingcorrectly
– if connections and/or piping are not sealed or cables are loose
AllpersonsworkingwiththeCondairCS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CSwithouttheexpresswrittenconsentof

3.4 Functional description
TheCondairCSsteamhumidierisanunpressurizedsteamgenerator.Itoperatesontheresistance
heatingprincipleandisdesignedforairhumidicationviaasteamdistributionpipe.
Water supply
Thewateristakenviaaltervalve(accessory“Z261”)tothesteamhumidier.Itreachesthesteam
cylinderviatheinletvalve(levelcontrolled)andtheopenwatercup.
Level regulation
Thewaterlevelinthesteamcylinderiscontinuouslymonitoredwiththelevelunit.Ifthewaterlevel
reachesapresetlevel(owingtotheevaporationprocess)thelevelunitsuppliesasignaltothecon-
troller.Thisopenstheinletvalveandthesteamcylinderislledup.Whenthepresetoperatinglevel
is reached, the level unit supplies another signal to the controller to close the inlet valve.
Thepressureequalizingpipebetweenthesteamconnectionandthelevelunitensuresthatthewater
levels are the same in the steam cylinder and the level unit.
Steam generation regulation
Thesteamisproducedinthesteamcylinderbytworesistanceheatingelements.Thesteampro-
ductioniscontrolledviaanexternalhumidistat(On/Offcontrol)oranexternalcontinuoushumidity
controller0...10V(continuouscontrol).
Flushing
Theevaporationprocessincreasestheconcentrationofmineralsinthewaterofthesteamcylinder.A
suitablevolumeofwatermustbeushedthroughthesteamcylinderfromtimetotimeandreplacedby
freshwatertoensurethatthisconcentrationdoesnotexceedaspecicvalueunsuitableforoperation.
TheCondairCSsteamhumidierperformsanauto-adaptiveushing.Thisconsistsofthefollowing
twoformsofushing:
– Automaticushingtakesplaceassoonasthewaterinthesteamcylinderexceedstheupper
operatinglevel(e.g.byfoamingofthewater).
– Flushing dependent on time performsthe ushing process atpreselectedtimeintervals(in
accordancewiththelocalwaterquality).
Automaticortime-dependentushingtakesplacedependingonthewaterqualityandtheoperating
data.Ifthelowestoperatinglevelisreachedduringtheushingprocess,theinletvalveremainsopen
untilthewaterlevelinthesteamcylinderhasreachedthenormalworkinglevelagain.Ifthelowest
operating level is not reached, the inlet valve is closed.

4.3.4 Inspecting the installed unit
Checkthefollowingpoints:
Is the unit in the correct place (see chapter 4.3.1)?
 Istheload-bearingcapacityoftheconstructiontowhichtheunitistobemountedsufcient?
Is the unit correctly aligned vertically and horizontally?
Is the unit properly secured (see chapters 4.3.2 and 4.3.3)?
 Istheunitcoverreattachedandsecuredwiththetwoscrews?

4.4 Steam installation
4.4.1 Steam distribution pipe
4.4.1.1 Positioning of the steam distribution pipe
The location for the steam distribution pipe should be determined at the time of dimensioning the
airconditioningsystem.Pleasenotethefollowinginstructionstoensureproperhumidicationofthe
duct air.
Calculatingthehumidicationdistance
The water vapour, emitting from the steam distribution pipes, requires a certain distance to be
absorbed by the ambient air so that it is no longer visible as steam. This distance is referred to as
humidicationdistance“BN”and serves as a basis for the determination of the minimum distances
from the upstream components in the system.

ϕ2:Supplyairhumidityafterhumidication
The calculation of the humidication distance “BN” is dependent on several factors. For a rough
estimationofthehumidicationdistance“BN”,thefollowingtableisuseful.Recommendedstandard
valueslistedinthistablearebasedonasupply-airtemperaturerangeof15°Cto30°C.Thevalues
only apply to steam distribution pipe 61-....
