The thinner tube is used for transporting liquid from the bottle to the liquid dosing head. The slightly
bigger tube is used for pumping air into the bottle. By adding air, pressure rises in the bottle. When
pressure reaches min. 0.3 to max 0.5 bar (4.4 to 7.2 psi) the micro dispensing valve in the dosing
head opens and liquid can ascend the liquid tube. The two tubes are further referred to as liquid tube
and air tube.
§ The liquid dosing head is inserted in the liquid dosing head
support.
− Connect liquid tube (1) at bottle (2) and at liquid dosing
head (3).

NOTICE
Damage on tube connectors because of mishandling!
If the tubes are not removed correctly, the connectors and therefore the pump module
can be damaged.
Wrongly cut tubing can cause leaking connections.
1 To remove tubes, press down ring on connector and pull out tube carefully.
2 Cut tubes with a tube cutter.
A tube in the air inlet to bottle (5) opens the valve of the air outlet. Never leave a tube which is
connected to the air outlet unconnected at the other end because pressure can not be built up.
You can connect up to 3 bottles to the pump module (7).
