operation.
• Pipe fittings between pump and pipeline have to be
tightened.
• The original operating manual of the pump is
available.
• Flange connections have to be checked if they are
fastened tightly.
• In and output openings for air-cooling of the motor are
free.
• All shut-off valves in the system are open.
• The precharge pressure of the membrane pressure
vessel is checked.
1. Open the vent screws on the pump according to the
original operating instructions of the pump set.
2. Slowly open the shut-off valves on the input side and
fill the system until pump medium runs out of every
ventilation borehole.
3. Close the ventilation screws, tighten pump ventilation
lightly.
4. Switching on the compact booster unit.
5. Loosen the vent screws and allow any remaining air to
