Material needed:
1. Sanitization kit (item MMSANKIT1)
2. Consumables for sanitization kit
(item MMSANSYFU)
3. Sanitizer (see table)
4. Purified water
• Remove the pump heads
• Place a sanitization kit on one pump head
support and lock it
• Lock the sanitization kit plug on the
other support
Optional: For faster sanitization, it is
possible to replace the plug by a second
sanitization kit and sanitize the complete
pump at once.
• Rotate the trigger counter clockwise,
the switch turns green
Figure 20: Trigger is rotated counter clockwise
• Take one sanitization funnel assembly

funnel on the kit
• Take a syringe (sanitization kit
consumable) and remove its plunger
• Place and lock the syringe on the kit
• Pour 60 mL of sanitizer in the syringe

syringe
• Open the funnel lid
• Pour puried water up to the 250 mL
indication level
• Put back the funnel lid
• Touch the switch to start the pump
Note: the switch starts blinking for
15 minutes while the following
operations occur:

and the sanitizer fills the pump internal
flow.
2. About 10 mL of sanitizer remains into
the syringe
3. The sanitizer remains in contact with
the internal flow for 15 minutes
