5.Place an empty container under dispense tip and activate the corresponding Dispenser until the clean soapy water is dispensed from the dispense tip.

8.Again, repeat steps 4 and 5 with the sanitizing solution. Once sanitizing solution is being dispensed, stop dispensing and allow the solution to sit for 5 minutes.

9.Repeat step 6 to flush out the sanitizing solution from the pump tubing.

10.Remove the mating connector from the bag connector.

11.Reattach the bag connector to product box.
