4. Functional Description and Device Composition
4.1 Mode of ActionThe immersion heater principleDepending on the output rating, one, three orsix heater elements are arranged within aclosed cylinder. Examplary given, the figurebelow shows the heater elements and othermain components of a heater element steamgenerator of the FLP series with 6 heater ele-ments.
The cylinder(s) are filled with either tap waterof varying quality, fully desalinated water orpartially softened water.
The heat introduced by the heater elementsheats up the cylinderwater to approx. 100 °C(212 °F), transforming the water into steam
with a temperature of approx. 100 °C (212 °F)This steam is virtually mineral-free and germ-free.
When fully desalinated water is used, the cy-linder water is almost totally clear of minerals.This situation guarantees a long lifetime of thecylinder(s) and the heater element(s), sincevirtually no hardeners will fall-out and no min-eral deposits will occur. Such, the number ofinspections and/or maintenance operationsrequired will be reduced to a minimum.
When tap water is used for operation, some ofthe minerals dissolved in the water are likely tosettle in the cylinder in form of solids of variouscompositions. However, most of the solids areflushed out by cyclic blow-down with the helpof a heavy-duty blow-down pump.

4.2 Operational sequenceThe steam humidifier is switched on bypressing the control switch on the front panelto the „I“ position. If the safety chain isclosed, the inlet multiple solenoid valve (twinsolenoid valve (25)*) in case of FLPxx-T andFLPxx-TSPA units, 4-fold solenoid valve(71)*) with FLPxx-TPRO units)* opens andwater is fed into the steam cylinder.
Filling level in the cylinder is controlled by alevel control device (27)*). In a plastic cylin-der, connected to the steam cylinder viahoses in the way communicating tubes areconnected, a sensor for continous propor-tional water level survey is located.
The cylinder water is periodically blowndown. For usage of the unit with fully deselin-ated water, the blow-down function may beblocked.
Water blow-down is achieved by means ofthe blow-down pump (32)*) that is continouslymonitored during unit operation. In case ofpump disruption, the HygroMatik steamhumidifier is shut off.
With normal water quality, blow-down loss isin the range of 7 to 15% of the steam amountproduced. Depending on water quality, a fullsteam cylinder blow-down is run every 3 to 8days.
Mineral deposits settle in the open areabelow the heater element(s) and areremoved through periodic maintenance. Theblow-down pump itself has wide openingsand can flush out smaller pieces of mineraldeposit. This extends the service life of theunit and reduces the required maintenanceinterval.
On blow-down, water flows from the pumpinto the drain hose system.
For maintainence purposes, the cylinderwater may be pumped out by pressing andholding the control switch in the „II“ position.
*) numbers indicated correspond with those inthe exploded view in the „Exploded view“chapter.
4.3 Internal Output SettingContinuous control is achieved by propor-tional driving (pulse width modulation) of theheater elements via one or both solid staterelays. In this way the humidifier can be pro-portionally operated across the entire outputrange of 5% - 100% of the nominal capacity. A power setting of 0% to 5% of the nominaloutput is possible, but not technically feasibledue to condensate losses in the steam line.
If the unit is equipped with more than 3heater elements, the output power provisionis accomplished in 2 stages. As long as acertain threshold was not reached, the heat-ing power necessary is solely controlled viathe solid state relays and the 3 heater ele-ments in a propotional manner (stage 1). Ifthe output power requested lies beyond whatis available in stage 1, three additional heaterelements are activated via a main contactorin a one-step operation mode (stage 2). Anypower requirement in excess of the stage 2rating is then proportionally supplied via thesolid state relays by the stage 1 operationalmode.
4.4 Mechanical ConstructionThe type of housing is designed for wallmounting. The steam cylinder is made fromstainless steel. Depending on the power out-put range, one, three or six heater elementsare encorporated.
4.4.1 FlexLine PlusFreshwater supply is accomplished bymeans of a twin solenoid valve that is alsoused for the SuperFlush functionality.
4.4.2 FlexLine ProcessThe units featuring the TPRO-control allowthe exceedingly precise steam control via afourfold solenoid valve. For this to work, theuse of fully demineralized water is manda-tory. A six-way solenoid valve is optionallyavailable, enabling the HyCool and HyFlushoptions.
Page 11
4.5 Thermal fusesThe devices of the FLP series have severalthermal fuses which are electrically con-nected in series. After one of the fuses hastripped, the device switches to the fault sta-tus. A device restart is required but is possi-ble only if the relevant thermal switches havecooled down or the thermal sensors havebeen unlocked.
The following fuses are available:
on the cylinder cover
• 1 thermal switch (Klixon) to protect against overheating of the steam cylin-der; the switch has a pin for manual reset after cooling down
• 1 or 2 (for devices with six radiators) thermal sensors with capillary tube for direct thermal monitoring of the radia-tors. One capillary tube each is con-nected to 1 to 3 radiators (depending on the device type). After a thermal sensor has been triggered, it must be reset manually (see maintenance description)
on solid state relays
The solid state relay (or two solid state relayson devices with higher power) is (are) ther-mally protected by a bimetal switch. Thebimetal switch returns to its initial positionduring the cooling process.

5. Mechanical installation
Risk of foot injuries!Prevent unit from dropping during installation!Helping hand of a second person is advis-able.
Risk of electrical shock!Hazardous electrical voltage.During installation, the unit must be discon-nected from power supply and securedagainst being switched on again. Theabsence of voltage must be ensured by ameasurement.
5.1 Environment Parameters tobe met and Mounting Recom-mendations
When selecting the installation site for thesteam humidifier, take the following intoaccount:
• The minimum clearances indicated inthe fitting measures section must beobserved in order to ensure adequateunit ventilation and allow for unobstruc-ted access in case of maintenance
• Protection class IP20• By design, HygroMatik steam humidi-
fiers are not qualified for outdoor instal-lation (electronical components andwater-bearing parts may be damaged)
• Ambient temperature must lie between+5 and +40 °C (+41 and +104 °F) inorder to protect the unit electronicsagainst damage; frost may damage thesteam cylinder, the solenoid valve andpump, as well as make hoses burst
• Relative humidity must not exceed 80% r.h., since values beyond may lead toelectronic malfunction or damage
• Installation in a closed room requiresaeration and, eventually, temperatureconditioning in order to meet the a.m.environmental conditions
• The steam humidifier should beinstalled as close as possible to thesteam manifold. Optimum perfor-mance is only guaranteed when steamand condensate hoses are kept short
• Make use of existing water connectionsfor supply and draining
• Hoses must be laid at a consistent 5 to10 % incline/decline; sagging and kin-king prevention is a must
• Mount the unit on a stable, preferablysolid wall offering the bearing capacityrequired (s. unit technical specificati-ons). If such a wall is not at hand, theunit may be attached to a stand bracketfirmly bolted to the floor
• For proper functioning of the level con-trol, plumb and level installation of theunit is required
• The steam humidifier rear panel heatsup during operation to a maximum of70 °C (158 °F). Take care that the con-struction on which the unit is to bemounted is not made of temperature-sensitive material

5.2 Absorption Distance BN The "absorption distance" (BN) is defined asthe distance from the steam feed to wherethe steam is completely absorbed in thetreated air. Within the absorption distance,steam is visible as mist in the air stream.
Condensation may occur on anythinginstalled within the absorption distance.
Although steam outside the absorption dis-tance (BN) is completely absorbed, it is notyet evenly diffused in the duct. If you plan toinstall any parts or devices inside the absorp-tion distance, such as sensors or elbows, werecommend increasing the absorption dis-tance using the formulae below. The absorp-tion distances required for certain installedfittings are distinguished by separate sym-bols and calculated as a multiplier of theabsorption distance BN.
The absorption distance has no fixed value,but depends on many factors. These aredepicted in the absorption distance nomo-gram below.
5.2.1 Determining the Absorption Distance
To determine the absorption distance, the fol-lowing parameters are required:
• Air humidity before humidification x1 in g/kg
• Air temperature after humidification t2 in °C (with steam humidifiers the change in air temperature due to humidification may be disregarded t1 or t2)
• Specific increase in humidity x in g/kg (can be determined in the h,x diagram)
• quantity of steam introduced in kg/h.
• air speed wL in m/s in air duct
• Total length lD of the steam manifold installed in the air duct
Length ID of the usable steam manifolddepends on the dimensions of the air duct.The length of the absorption distance can bereduced by using multiple steam manifolds(also see section on the steam manifold).
Method:Graphically determine absorption distanceBN using the absorption distance nomogram(also see Section „Absorption DistanceNomogramm“). Enter the value of the param-eters enumerated above into the respectivequadrants. The resulting point of intersectionindicates the value of the desired absorptiondistance BN.

5.3 Steam Manifold
5.3.1 General installation guidelines
When installing steam manifolds, pls. followthese guidelines:
Positioning within duct• Install the steam manifold as close as
possible to the steam humidifier in order to minimize steam loss through condensation
• Steam manifold placement on the sup-ply side of the air duct is preferable
• Install steam manifold strictly horizontalin order to ensure proper condensatedrain
• Shown installation and positioningdimensions are based on empiricvalues. Special environmental conditi-ons may require adjustments. Payspecial attention to avoid condensategeneration in air duct
Allowable pressures• Max. allowable pressure in air duct is
1500 Pa/.218 PSI (exemption: SLE02,SLH02, KIT E02 and KIT H02 onlyallow for 1200 Pa/.174 PSI)
• On suction side, max. -500 Pa (.07PSI) is tolerable
• With high-pressure air conditioningsystems, modifications of the unit‘sdrain hose system may possibly berequired depending on the overall pres-sure situation. These modificationsmust be coordinated with yourexpert dealer.
Water drain• We point out that according to the Ger-
man Association of engineers (VDI)guideline VDI 6022, a water drain mustbe provided within the absorptiondistance inside the air duct
When increased airflow speed is encoun-tered• Air flow rates beyond 3m/s (9.84 ft/s)
may lead to condensate drainage prob-lems at the steam manifolds due tovacuum built-up. A possible remedy istwisting the steam manifold in its hori-zontal axis by few angular degrees. Incase of problems, pls. consult yourexpert dealer.
5.3.2 Recommendations for dimen-sioning
The recommendations given below arebased on homogenous air flow in the duct.
Horizontal installation of steam manifold

5.4 Steam line and condensatehose layout
Because of the high requirements on hosematerial under the operating conditionsgiven, it is recommended to use genuineHygroMatik hoses only.
5.4.1 Guide lines for steam linedesign
• Steam hose nominal diameter must not be smaller than the steam outlet of the HygroMatik steam humidifier (do not restrict the cross-section, otherwise back pressure will increase)
• Steam hoses must be laid without sags and kinks and with a continuous slope of 5-10% (otherwise sags may result).
• Steam hoses must be supported every 500 mm (20 inches) by clamp brackets
• Steam hoses should be kept as shortas possible. Implement lengths be-yond 5 m (16 ft.) as insulated fixed pip-ing to keep energy loss and conden-sate generation to a minimum. Beyond10 m (32 ft.) insulated installation is amust. Fixed piping is generally recom-mended for straight steam line seg-ments
• When 2 steam manifolds are in use(other than with a standard implemen-tation), place steam Y piece as close aspossible to the steam manifolds. Such,for the main part of the piping just onesteam hose is required and condensateloss is minimized
• Allow easy access to the steam pipe/steam hose installation
• Pressure conditions within the duct are influenced by device steam output, steam line layout and the duct composition itself. In some rare situations it may become necessary to optimize steam line layout for achieving the results intended
• Respect minimum bending radii: DN 25 Steam hose: Rmin = 200 mm/8“ DN 40 Steam hose: Rmin = 400 mm/16“
5.4.2 Condensate hose layout(only for electrode steam humidifiers)
The condensate hose may be run from thesteam manifold back to the steam cylinder,as depicted in the schematic drawing belowwith concern to installation type 1. Alterna-tively, the condensate hose may be feddirectly in a wastewater pipe or a drain (s.installation type 2).
Should condensate return into the steam cyl-inder be intended, the connection stub on thecylinder upper part must be drilled out firstwith a ANSI drill size „O“ drill. To do so, thesteam cylinder must be removed from thehousing (s. maintenance chapter, section„Steam cylinder removal and reinstallation“).In case of a console instead of a housing, thecylinder is to be lifted off the cylinder base fordrilling the stub or may even remain in place.
For heater element humidifiers:If condensate return is necessary, pleasecontact the HygroMatik hotline.

6. Water connection
Risk of scalding!Very hot water to be found in and around thesteam humidifier during and after operation.Have all installation work done by expert staffin order to avoid scalding hazards due toimproper water guidance.
Risk of electrical shock!Hazardous electrical voltage!Before starting installation work ensure thatthe unit is not yet connected to the powersupply.
General Rules
• Obey local water utility regulations• Verify that necessary safety measures
have been taken – in compliance with either German Technical and Scientific Association for Gas and Water (DVGW) guidelines (DIN EN1717) or local regulations – that eliminate back-flow of polluted water into drinking water treatment facilities. This may require the installation of a system sep-arator of the CA type (minimum mea-sure, allowable only when free discharge into the drainage system is given). Within the humidifier, a double check valve (58) is located in the water supply line. It prevents - in accordance with DIN EN 61770 - the backflow of water.
• Supply water must not exceed 40°C (104°F)
• Allowable range of water pressure: 1 to 10 bar /14.5 to 145 psi (100 x 103 to 100 x 104 Pa)
• For connection to the water supply pipe, make use of a water hose
• Blow-down water must drain freely
• As installation or retrofit option, the DVGW-conform HyFlow system sepa-rator is available for the HygroMatik electrode steam humidifiers (except SLE 02).
• You can also use a standard BA/CA system separator for the corresponding fluid category.
6.1 Feed water qualityThe following applies to electrode steamhumidifiers (ELDB):
• Only use drinking water* or treated drinking water (partially softened or mixed deionised water) without chemi-cal additives and with a conductivity between 200 and 800µS/cm. Beyond conductivity levels of 800µS/cm up to a maximum of 1250µS/cm and below conductivity levels of 200µS/cm to a minimum of 125µS/cm, special adjust-ments are required. In this case please contact your specialist dealer.
The following applies to heater steamhumidifiers (HKDB):
• Only use drinking water* or treated drinking water (partially or fully softe-ned, mixed or normal deionised water) without chemical additives.
• When using deionised water, there must be a minimum conductivity of 3µS/cm. Do not use copper or brass for the humidifier inlet and outlet pipes. These materials can be destroyed by the deionised water/ condensate. Sui-table materials are, for example, stain-less steel or plastic pipes.
• From a water hardness of 15°dH, we recommend upstream water treatment.
• The feed water that is used (indepen-dent of the type of treatment) must have a minimum pH value of 6.5.
• FLP-TPRO units may only be operated with softened water
* according to the drinking water regulation of 08.01.2018
WARNING!
WARNING!
Page 24
6.2 Operation of electrode steamhumidifier with softenedwater
Do not use softened water unless specialmeasures are taken!Operation with partially or fully softenedwater makes it necessary to adjust the blow-down parameters to a higher blowdown fre-quency.
Even if the HygroMatik steam humidifier issupplied with partially softened water, theremaining hardness builders can cause finecrystalline deposits. These can be set downin the sieve area of the steam cylinder bottompart and cause blocking of the sieve.
The following applies to electrode steamhumidifiers (ELDB):Softened water may cause• unacceptably high conducivity• the formation of salt bridges
between the electrodes and the electrode leads on the inner surface of the steam cylinder upper part
• foaming in the steam cylinder
Salt bridges may cause electrical arcs. Theseare indicated by the presence of blackgrooves in the top part of the cylinder. Thecylinder must then be replaced to prevent fur-ther damage to the cylinder material, as wellas short circuits which may trip main circuitbreaker.
Foam may come into contact with the maxi-mum level sensor electrode and trigger themax. level status message despite the cylin-der not being full yet and the nominal currentnot yet established.
With softened water, at operating tempera-ture conductivity level usually is higher thanis the case with tap water.
If using a water softening system, we recommend diluting the softened water with normal tap water to produce an overall hardness between 4-8°gH.
The following applies to heater steam humidifiers (HKDB):• Operation with fully softened water
(0°dH) is possible
6.3 Water supply
Foreign material in water supply pipe maycause premature wear of the solenoidvalve.Flush the water supply pipe before makingconnection to the solenoid valve. This is ofparticular importance in case of a newlyinstalled pipe.
» Install a shut-off valve (SV) in the supply line.
» Install a water filter (WF) if required due to bad water quality.
• Shut-off valve (SV) and water filter (WF) are not included in the delivery
• For connection to the water supply line, the water hose (56) with cap nuts (1) on both ends supplied with the unit may be used.
• In case of no safety device for drinking water protection according to DIN EN 1717 present in the house installation system, a system separator at least of the CA type or use of the Hyflow retrofit option (only for electrode steam humi-difiers) is mandatory.

*) the numbers refer to the exploded view inthe chapter with the same name.
Make connection as follows:
» Attach cap nut with inner seal ring toinlet screw joint on the humidifierhousing and tighten.
Do not overtighten the cap nut!Excessive tightening will destroy the fitting.
» Screw the other hose end cap nutwith its inner seal on a customer-provided water tap (cap nut internalthread is ¾“) .
» Strainer must be placed inside the solenoid valve
6.4 Water discharge
Risk of scalding!During blow down, up to 0.3 l/sec (08 gal./sec) are being drained with a temperature ofabout 95 °C (203°F).Ensure that the drain hose is reliably fas-tened and wastewater can drain freely andpressureless.
Humidifier installation location and wastewa-ter discharge must be on the same pressure level. In case of a drain connection on posi-tive pressure, pls. consult your expert dealer.
Guidelines for water discharge composi-tion
• Use original HygroMatik water drainhose
• Do not buckle drain hose• Use a drain pipe and outlet pipe made
of suitable material (temperature resis-tant up to 95°C (203°F); with wastewater cooling HyCool up to 60°C)
• In case of a free outlet according to DINEN 1717, a system separator for liquidcategory 4 is required for the waterconnection.
• In all other cases, use a system sepa-rator for liquid category 5.

How to proceed
» Run a 1 1/4 " drain hose of 250 to1000 mm (10 to 40 inch) length intoa pressure-free outlet according toDIN EN 1717. The hose must beguided sideways of the humidifier toprevent ascending vapor from con-densating on the humidifier`s hous-ing.
Valid for all steam humidifiers (KITS are notincluded):
» Fit drain hose to connection stub on humidifier housing bottom side.
» Slide pump drain hose onto one of the grounding clips (s. fig. below).
» Slide overflow hose of the HyFlow system separator (if present) onto the other grounding clip.
Grounding clip functioning
The two grounding clips attached to the innersurface of the housing drain stub are in directcontact with water and shunt potential resid-ual electric currents away from the housingduring blow-down and in case of a cylinderwater overflow.
Between the pump drain hose jacket and theinner surface of the cabinet drain connection,a gap exists due to the diverging diameters. Ifwater collects on the base plate, it will flowthrough this gap into the drain hose and theninto the drainage system.
With the optional wastewater cooling systemHyCool (not available for FLP-XX-TPROunits), HygroMatik offers an option for limi-ting the steam humidifier wastewater temper-ature in order to protect thermosensitivewastewater pipe lines. By blending with tapwater during blow-down, wastewater temper-ature is below 60°C (140°F) as long as inletwater temperature does not exceed 30°C(86° F).

9. Maintenance 9.1 General For the achievement of a long unit life span,regular maintenance is a must. Maintenanceworks to be performed refer to unit assem-blies that underlie either mechanical or elec-trical wear and tear, or may be impeded byresidues in their proper functioning.
A steam humidifier's optimal performanceand the maintenance intervals required pri-marily depend on the water quality encoun-tered and the amount of steam produced. Aparticular water quality may shorten orlengthen maintenance intervals. The amountof residues found in the steam cylinderallows for a hint on future maintenance inter-vals.
Another scenario influencing the unrestrictedunit availability is the main contactor lifetimein terms of a maximum number of switchcycles allowed, as indicated by its manufac-turer. Unit control monitors the number ofswitch cycles and produces a service mes-sage when the max. number is reached.
9.1.1 Service messagesIn case of a service message produced, theHygroMatik logo in the main section of thetouch display (for explanation s. „FlexLinecontrols“ manuals) is blanked. Instead, aframe is shown with the service icon in itand a „Service message (xx)“ („xx“ indexesthe message code). When the messageframe is touched, the service message is dis-played in clear language.
The service messages are listed in detail inthe „FlexLine controls“ manuals. Followinghereafter, pls. find 2 service messagesdenoted as examples:
• „Steam_amount_counter“ is output when the pre-set produced steam amount is reached. Maintenance of the device is necessary.
• „Cycles_main_contactor x“ is indicated when the number of cycles pre-set for main contactor „x“ (x = 1...5) is reached. The main contactor should then be replaced and the counter reset (s. „Service“ submenu in the „FlexLine controls“ manuals).
After a „Steam_amount_counter“ message,maintenance work mainly encompasseschecking and cleaning all of the unit partsincluding the steam cylinder inside, and a unittest run.
As part of the maintenance work, screw ter-minals and plug connections must bechecked every time. If required, retighteningthe teminal screws is a must as well asensuring tight fit of all of the plug connec-tions.
Since steam and condensate hoses are sub-ject to wear as well, hoses must also bechecked regularly for tightness, flexibility andfirm seating.
Seals are wear parts. As such, seal integritychecks and replacement is also a part of theregular maintenance work.
9.1.2 Service messages for preven-tive maintenance
HygroMatik steam humidifiers continuouslymonitor the performance of the followingfunctional areas:
• Blow-down operations• Cylinder filling
When reaching pre-set trigger levels, unitcontrol outputs preventive service messagesthat relate to the corresponding functionalarea.
The functional area addressed should thenbe checked at short term and maintenanced,if required (s. „FlexLine controls“ manuals,„Service messages and warnings“ chapter“).

9.1.3 Safety instructions for mainte-nance
Risk of electrical shock!Hazardous electrical voltage. Unit must beswitched off and protected against restart byexpert staff (electricians or expert personnelwith equivalent training) before any mainte-nance work is commenced.
Risk of skin burning!Hot steam cylinder during operation and forsome time afterwards.Drain steam cylinder before any maintenancework is commenced. After that, wait approx.10 mins before starting maintenance work.Check steam cylinder temperature by cau-tious approximation with hand (do not touch!).
Risk of scalding!Water pumped or drained from the steamcylinder may have a temperature of up to 95°C. Wear proper PPE (Personal Protection Equip-ment)!
Take care of ESD protection!The electronic components of the humidifiercontrol are very sensitive to electrostatic dis-charges. In order to protect these compo-nents during maintenance, steps must betaken to guard against damage from electro-static discharge.

9.2 Maintenance frame work when unit is operated with fully demineralised water and condensate
Instructions on maintenance and cleaningintervals are entirely based on empirical data.
9.3 Maintenance when unit is operated with tap water or partially softened water
No precise maintenance intervals can bespecified because these always depend onwater quality and the amount of steam gener-ated. It is advisable to adjust the frequency ofmaintenance to the specific operational experi-ence. HygroMatik recommends to check theopened steam cylinder 1 or 2 weeks after ini-tial commissioning in order to quantify theamount of residue produced so far, allowingfor determining future maintenance intervalsand/or the adjustment of blow-down cyclespossibly required.
Blow-down cyclesThe vaporisation process causes hardnessbuilders (calcium) in form of solids of variouscompositions to fall out within the steam cylin-der. Cyclic blow-down by means of a powerfulblow-down pump followed by fresh water refillsremove parts of this solid built-up.
Water qualityWhen tap water is used, it must be taken intoaccount that cleaning intervals shorten as thecarbonate hardness level increases. As a gen-eral rule, it is preferable to operate the unitwith fully demineralized water since ope-rationwill not be affected by mineral deposits andflushing loss will be minimized.
Possibly, maintenance intervals may beextended by moderately increasing the blow-down cycle rate. Please consult your expertdealer.
Cycle time Maintenance work4 weeks afterinitial commis-sioning
• Visual inspection of electrical and mechanical connections.• Visual inspection of level control.• Visual inspection of the steam cylinder interior.

9.5.3 Releasing the thermical safetydevices
Variety of thermal protection devices inuse
For overheat protection, the steam humidifieris equipped with one or two thermo switches,depending on the power output rating. Theyare mounted on the steam cylinder cover.The thermo switch/es is/are coupled to theheater element/s by means of a capillarytube. Each of thermo switch controls 1 to 3heater elements. Thus, with 6 heater elementunits, each one of the thermo switches isassigned to a group of 3 heater elements.
For additional safety in case of one of thethermo switches beeing defective, a Klixonthermo switch is screwed to the cylindercover.
The mounting positions of a single thermoswitch and the Klixon are shown in the nextsection in an exemplary representation.
Supplementary to the thermal protectiondevices in conjunction with the steam cylin-der, the solid state relay/s is/are protected bybimetal switches to avoid damage introducedby inadequate ventilation due to e.g. ventholes that are obstructed.
From an electrical point of view, the thermoswitch/es on the cylinder cover, the bimetalswitch/es on the soid state relay/s as well asthe Klixon thermo switch mounted on the cyl-inder cover are all wired in series. If one ofthe devices mentioned triggers due to anoverheat situaton, the main contactor K1switches off and controls enters the „120“error state (i.e. „Thermo switch“). Steam pro-duction is then interrupted. A unit restart isrequired which is, however, only possibleafter the bimetal switch/es has/have cooleddown and/or the thermo switch/es and/or theKlixon thermo switch (see sections 9.10.2and 9.10.3) were unlocked.
In case that a thermal protection device trig-gers repeatedly, check for possible causeprior to any further use of the unit.
9.5.4 Unlocking of a thermo switchon the cylinder cover
Whether a thermo switch and, if so, which ofthe devices, has triggered, may be detectedby a passage measurement (let the unit cooldown before starting the measurement!).
Unlocking is then accomplished as such:
Slightly push down the red button (see fig. insection 9.11) protruding a few milimetersfrom its holder. This will make the buttonreturn to its original position and unlock themechanism.
Relasing a thermo switch does not erase thefault message in the control fault memory.

9.5.5 Unlocking of the Klixon thermo switch
Whether the Klixon thermo switch has trig-gered, may be detected by a passage meas-urement (usually, when overheat isencountered, the thermo switch/es trigger).
Unlocking is accomplished by pressing theunlocking pin located between the electricalconnection contacts of the Klixon switch (seefig. in section 9.11).
