Bitte lesen Sie diese Hinweise vor Installation oder Gebrauch dieser Ausrüstung sorgfältig 
durch. 

1.  Das in diesem Handbuch beschriebene Gerät darf nur von geschultem Personal bedient 

werden.  Alle  Anpassungen,  Wartungsarbeiten  und  Reparaturen  müssen  entsprechend 
der Vorgaben in diesem Handbuch und von einer kompetenten Person, die mit den damit 
verbundenen Gefahren vertraut ist, durchgeführt werden. 

2.  Es ist wichtig, dass sowohl das Bedienungs- als auch das Service-Personal zusätzlich zu 

den  detaillierten  Anweisungen  in  diesem  Handbuch  ein  sicheres  Arbeitssystem 
einsetzen. 

3.  Mit  Ausnahme  der  Teile,  deren  Wartungsverfahren  in  diesem  Handbuch  beschrieben 

sind,  enthält  dieses  Gerät  keine  weiteren  Teile,  die  vom  Benutzer  gewartet  werden 
können.  Das  Entfernen  von  Abdeckungen  und  Versuche  von  hierfür  unqualifiziertem 
Personal,  Anpassungen  oder  Wartungsarbeiten  durchzuführen,  haben  zur  Folge,  dass 
die Garantie verfällt und können zusätzliche Reparaturkosten auslösen. 

4.  Es ist jederzeit auf die sicherheitsrelevanten Daten sämtlicher verwendeter Chemikalien 

Bezug  zu  nehmen.  Allgemein  anerkannte  Labormethoden  zum  sicheren  Umgang  mit 
Chemikalien sollten eingesetzt werden. 

5.  Besteht der Verdacht, dass die Sicherheitsvorrichtungen in irgendeiner Weise beschädigt 

wurden,  muss  das  Gerät  außer  Betrieb  genommen  und  gegen  weiteren  Gebrauch 
gesichert  werden.  Die  Störung  sollte  der  zuständigen  Serviceeinrichtung  unverzüglich 
gemeldet werden. 

Leggere attentamente queste istruzioni prima di installare o utilizzare il dispositivo. 

1.  L'unità  descritta  nel  presente  manuale  è  stata  realizzata  per  essere  utilizzata  solo  da 

personale  che  ha  ricevuto  l'apposita  formazione.  Qualsiasi  operazione  di  regolazione, 
manutenzione  e  riparazione  deve  essere  effettuata  sulla  base  di  quanto  indicato  nel 
presente manuale da personale qualificato consapevole dei rischi connessi. 

2.  È  fondamentale  che  il  personale  operativo  e  il  personale  addetto  alla  manutenzione 

utilizzino un sistema di lavoro sicuro, oltre a seguire le istruzioni specificate nel presente 
manuale. 

3.  Oltre  a  quelli  indicati  nelle  procedure  di  manutenzione,  all'interno  di  questo  dispositivo 

non  sono  presenti  altri  elementi  sui  quali  è  possibile  effettuare  interventi.  La  rimozione 
delle protezioni e qualsiasi tentativo di regolazione o di manutenzione posto in essere da 
personale non qualificato invaliderà la garanzia. In questi casi, sarà necessario pagare un 
importo per le riparazioni effettuate. 

4.  È sempre necessario fare riferimento ai dati sulla salute e sulla sicurezza forniti con le 

sostanze chimiche utilizzate. Adottare le procedure di laboratorio generalmente accettate 
per la gestione delle sostanze chimiche.
