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.

1.6 MountingtheNozzleHeater
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
offinthecontrolunitbeforeyoustart.


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
tubeiscorrectasshowninthepicture.


Step4

Screwthenozzleunit“NUMDH‐230tffix”manually
ontothefluidbox.Screwitlooselyforroughly1.5to
2rotations.Itshouldn’tbetightyet.
Finallyconnecttheheaterwiththeheatercontrol
viaaheatercable.
