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

2 Place the sealing ring (1) on a flat stable surface, e.g., a
table or a workbench, with the wider end downwards.
3 Take the end of the liquid tube and press it into the sealing
ring.
ð This is the dosing-head end of the tube. The opposite
end is the bottle end.
4 Thread the fastening nuts (2), paying attention to the orien-
tation.
5 Thread the sealing ring (3) from the bottle end of the tube. Pay attention to the orientation.
6 Using the micro dosing valve tool, slide the sealing ring
until the distance (D) is enough for the tube to reach the
bottom of the bottle. Recommended distances for typical
bottle volumes are listed next.

1 Insert the dosing-head end of the tube (1) in the dosing
head (2).
2 Tightly fasten the fastening nut to the dosing head.
3 Insert the bottle end of the tube through the corresponding
hole in the bottle cap (3). The tube should reach the
bottom of the bottle.
4 If needed, attach the suction filter (4) to the bottle end of
the tube.
5 Tightly fasten the fastening nut to the bottle cap.
6 Screw the cap to the bottle (5).
The suction filter is used to ensure that no particles or
impurities are carried through the liquid dosing head. Using the
suction filter will extend the life time of the dosing head.
