Alerts and errors
With a non-disconnectable infusion set do the following:
If no error E4: OCCLUSION occurs, the occlusion was within the infusion
set. Change the infusion set. Prime the new infusion set and insert it in a
new infusion site. Put you insulin pump into RUN.
If however still an error E4: OCCLUSION occurs, the cartridge can be the
cause of the occlusion. Remove the cartridge and activate the PRIMING
function (without cartridge and without attached adapter and infusion set).
If no error E4: OCCLUSION occurs, the occlusion was within the
cartridge. Activate the CHANGE THE CARTRIDGE function. Insert a new
filled cartridge with attached adapter and a new infusion set into the
insulin pump. Prime the new infusion set and insert it into a new infusion
site. Put you insulin pump into RUN.
If all these corrective actions do not help and the error E4: OCCLUSION
continues to occur, contact your doctor or healthcare team for an
alternate therapy plan. Contact your local Customer Care Area for further
assistance.

Remove your infusion set from the infusion site
and afterwards from your insulin pump. Activate
the PRIMING function without an attached
infusion set. Hold your insulin pump with the
adapter pointing downwards to avoid that insulin
flows through the adapter into the cartridge
compartment.
