Tubes definition

The liquid tube is the thinner tube (1) used for transporting liquid

from the bottle to the liquid dosing head. The air tube is the

slightly bigger tube (2) used for pumping air into the bottle. By

adding air through the air tube, pressure rises in the bottle. When

the pressure reaches the configured target pressure, between 0.3

and 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. .

Preparing the liquid tube

CAUTION

Injury due to leaking liquids

Wrongly cut tubing can result in leaking connections.

− Cut the tubes with a tube cutter or a sharp knife.

The liquid dosing head is inserted in the liquid dosing

head support of the bottle.

1 Using a tube cutter or a sharp knife, cut a sufficient

amount of tubing. The appropriate length mainly

depends on the distance between the bottle and the

dosing module while dosing.

Recommended length: about 0.9m

ð This is the dosing-head end of the tube. The

opposite end is the bottle end.
