You start the pumping process by pressing the  button and you terminate it by pressing the  button again once the
delivered the delivered volume has reached 100 ml. Confirm the value by pressing the Menu button and then use the
 and  buttons to calibrate other pumps. Press the Esc button to return to the basic function of the dosing pump.
For example: 100 ml correspond to 212 rotations.
Note: The hoses need to be vented manually prior to each calibration process (if this has not been done already). Other-
wise there could be a difference of up to 20 ml of liquid, depending on the length of the hose.
6. Placing the dosing pump:
The dosing pumps are self-priming and should always be placed above the liquids to be dosed. This prevents draining
the dosing liquids in the event of leaks. To prevent a return flow from the aquarium or the filter sump, the feed lines
must not hang in the aquarium water. Hint: In this respect, easy and secure installation is provided by the Dupla Marin
Tube Holder (Item no. 81564), which can be used to fasten the hoses securely on the aquarium. The delivery head
should not exceed 2 metres.
