Every 10,000 dispensed items or, however, every 6
months, a small maintenance intervention on the infuser
unit is required for optimising its operation.
For performing the maintenance operations it is neces-
sary to remove the unit by following these steps:
- Disconnect the espresso coffee outlet nozzle from
the unit by rotating it by 90° from the rod and pulling it
outside.
- Disconnect the fresh brew coffee outlet nozzle from the
unit by rotating it by 90° and pulling it outside.
- Act the unit end stop lever rotating it until the horizontal
position.
