5.2 Inserting and replacing Tube
Insert or change the tube by:
1. Stop pump and switch off.
2. Turn pivoted lever
3
laterally to the left or right in position 2 and remove the cartridge
4.
3. Insert tube
7
in the gap formed and pull a bit tight at the ends.
4. Insert cartridge
4
, press downward and turn pivot lever
3
back into position 1 swinging to the resting
position.
6. Setting the optimum Tube Pressure
1. To check the pressure at the discharge side, insert the end of the tube in a water bottle.
2. Start pump.
3. Loosen lock nut
2
by turning to the left. Unscrew set screw
1
by turning left until pumping ceases (no
bubbles).
4. Carefully increase the pressure on the cartridge
4
by turning set screw
1
to the right until air bubbles are
pumped from the discharge side.
5. Turn another ¼ turn to right to ensure pumping reliability.
6. Secure lock nuts
2
by turning to the right.
Important:
If counter pressure exists, the pressure setting must be carried out under operating pressure.
This aforementioned setting can now be retained unchanged for the same operating conditions, i.e. for the
same counter pressure and the same pumping tube
Changing the tube is therefore significantly simplified as only the pivot lever
3
must be swung out and in (Pos
2 and Pos 1).
7. Changing the Operating Conditions
Renewed setting of the pressure is only required if the operating conditions, tube size or counter pressure
are changed.
Important!
When changing the tube size, it must be ensured that the used cartridge 4 is properly matched to suit
the selected tube size. This can be checked against the lettering on the cartridge.
8. Service and Cleaning
8.1 Outside cleaning
In case of soiling by liquids or after a longer period of use, simply clean with a cloth dampened with
household washing up liquid dissolved in water or alcohol.
