Thismanualshowsyouhowtosetupanapplicationforhotmeltdispensing.Thesetup
makesuseofaVERMESMicroDispensingSystemwithnozzleheaterandcartridgeheater.

CAUTION!(Hightemperatures)
Theheatersyouwillusecanreachtemperaturesofupto180°C.Forsuchhigh
temperaturesthereisadangerofsevereburnsandinjuries.Useheatresistantgloves.

1.1 GeneralIntroduction
Thismanualexplainsstep‐by‐stephowtomountandworkwithanapplicationforthe
dispensingofareactivehotmeltadhesive.Itstartswiththenecessarypartsandtools;
followedbyanexplanationofhowtomountthenozzleandcartridgeheaters.Themanual
describeshowtodispenseandaddssometipsandtricksaboutcleaningthesystem
afterwards.Finallyaselectionofrecommendedfurtherreadingmaterialislisted.

Bewarethatsomepicturesmightdifferslightlyfromtheactualproduct.

Forbestresultsthedeadvolumeofthemediacarryingchannelsshouldbeassmallas
possibleandbemadeofthermallysimilarmaterialstoavoidtemperaturefluctuations.All
partsarechosensothattheyhaveagoodheatconductance,butarealsosufficientlyheat
resistant.Forthesamereasonitisimportanttouseavalvewithaircooling.

SincetheinternalcontroloftheheaterviaMDCcanonlyworkwithoneheater,youwill
needanexternalheatercontrol.YoucanusetheheatercontrolMHC3001(orderno.
1012948)foroneheaterortheheatercontrolMHC3002(orderno.1012949,seepicture
below)fortwoheatersanduseittocontrolbothheaters.Theadvantageofusingthe
MHC3002forbothheatersisthatthepossibleminimumdelaycanbesetshorter.

Beawarethatthepicturesinthischaptermightdifferslightlyfromtheactualproduct,
especiallyifyouuseaMDH‐230tfrasnozzleheater.

Step1

GreasetheO‐ringHeater‐fixthoroughlyandpushit
ontothebearingMDH230t‐fix.

CAUTION!Makesuretheheateristurned



Step2

ScrewthebearingMDH230t‐fixwithmountedO‐
ringHeater‐fixontothefluidbox.

IMPORTANTNOTE!ThebearingMDH230‐tf
cannotbetightened.Screwittotheendof
theendlessthread.


Step3

Pushtheheaterontothebearing.TheO‐ringhasto
fitperfectlyintothebore.
Pleasemakesurethatthepositionoftheheating


CAUTION!(Hightemperatures)
DonottouchthenozzleareaofthevalvewhiletheheaterisON.Forhightemperatures
thereisadangerofsevereburns.OnlytouchtheareaaftertheheaterisswitchedOFFand
therewassufficienttimefortherelevantpartstocooldown.Useheatresistantgloves.

Attachthecompressedairsupplyfortheaircoolingsystemofthevalve.TheMDV3200A‐


Nowyoucanstarttheadjust.

IMPORTANTNOTE!
Makesurethesystemisalwayscleanedbeforeyoustartanadjust.Thepresenceof
dirtparticlesjammedbetweenthetappetsurfaceandthenozzleinsertwould
compromisetheresults.Alsoalwaysmakesurethenozzleunitisloosebeforeyou

Step1

Bringtheheatertothedesiredtemperature.
Waitafewmomentsforthesystemtosettle
inthistemperature(seetableontheprevious
page).
Starttheadjustbypressingthebutton[adj].



Step2

Screwthenozzleunit“MDH230tf‐fix”


CAUTION!Pleaseensurethatthe



Step3

Screwthenozzleunitslowlyawayfromthe

Thevalueshowninthedisplayshouldbein
therangeof985–1000.

CAUTION!Ifthevalueisnotstableor

1.9 HotMeltDispensing
Afteryouhavefinishedtheadjust,youcanturnONthecartridgeheatertoheatupthe
cartridgewithyourreactivehotmelt.Aswiththenozzleheater,itwilltakesometimeuntil
thetargetedoperatingtemperatureisreached(dependingonsetup,mediumandtarget
temperaturethiscantake10to20min).

IMPORTANTNOTE!
Maximumpossibletemperaturefortheseheatersis180°C.

Oncetheoperatingtemperatureisreached,youcanopenthecompressedairsupplyandset
thesupplypressure.

Nowyoucanstarttodispenseyourhotmeltapplication.

Whendispensingwithadefinesnumberofpulsesorininfinitemode,theresultcouldbe
cleanlinesasinthepicturebelow,whichshowsanexamplewithareactivehotmelt

1.10 DismountingandCleaning
1.10.1 RemovingtheReactiveHotMelt
Beforeyouswitchoffthesystem,youwanttomakesuretoemptyitoftherestofthe
reactivehotmeltadhesive:
1. Turndownthecartridgeheaterto60°C.Waituntilthetemperaturehasreachedthislevel.
2. Screwoffthecartridgewithreactivehotmeltandremoveit.
3. Screwinacartridgewithnon‐reactivehotmeltasacleaner.
4. Increasethetemperatureto90°C.
5. Setthenumberofpulsesintheparametersettingstoca.15000pulses.
6. Keepdispensinguntiltherestofthereactivehotmeltisremovedfromthesystem.
7. Turnofftheheaters.

IMPORTANTNOTE!
Therewillbearemainderofthenon‐reactivehotmeltleftinthesystem.Whenyoure‐start
theapplicationagainwithoutcleaning,youhavetodispenselongenoughwiththereactive
hotmelttoclearthisremainderfromthesystem,beforeyoucanbeginwiththeapplication.

1.10.2 Dismounting
Ifyouwanttodismountthesetupcompletely,makesureeverythingisturnedoff.Youhaveto
waitlongenoughfortheheaterstocooldownsufficiently,beforeyougoon.Essentiallyyouwork
inreverseorderfromthemounting.
1. Disconnecttheairsupply.
2. Disconnectbothheaters.
3. Turnthecartridgeairpressureforcereliefcounter‐clockwisetodisconnectit
fromthemountingbase.
4. Pullthecartridgeairpressureforcereliefoffofthecartridge.
5. ScrewoffthecartridgefromtheLuer‐Lockconnectorandpullitoutofthe
cartridgeheater.
6. Pullawaythecartridgeheater.
7. Screwoffthenozzleunit,usingtoolMDT302.
8. Pullofftheheatercarefully.
9. ScrewoffthebearingMDH230t‐fix.
10. RemovetheO‐ringfromthebearing.O‐ringsshouldnotbecleanedinan
ultrasonicbath.
1.10.3 Cleaning
Cleaneverything.Makesurethatyourcleaningfluidhasahighenoughflashpoint.
Otherwisethereisthedangerofanexplosionduringyournextapplication,sincesome
remaindersofthecleaningfluidmightstayinthesystem.Moreinformationaboutcleaning
youwillfindinthe“QuickReferenceGuideCleaningandMounting”(seechapter1.11,
