•
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
escape.
6.
Open shut-off valve.
7.
Loosen the vent screws and allow any remaining air to
escape.
8.
Tighten the vent screw.
9.
Check if the pump runs smoothly.
10.
Close the pressure-side shut-off valve and check
whether the pump reaches the zero point.
11.
Close shut-off valve
Pump switches off
6.1.3 Switch on
The compact booster unit is filled and ventilated
1.
Insert mains plug in the electrical socket.
6.1.4 Start-up checklist
6.2 Limits of operating range
DANGER!
Exceeding the limits
Damage to the pump unit!
Observe the operating data specified in the data
sheet.
Avoid operation against closed shut-off valve.
Never operate the pump set outside the limits
specified below.
DANGER!
Risk of explosion!
Exceeding the limit of use regarding to the pumped
medium.
Never pump different fluids that can chemically react
with each other.
Never pump a flammable medium with a medium
temperature above the ignition temperature.
CAUTION!
Excessive temperature difference between medium
and pump
Damage of the machine!
The temperature difference between medium and
pump must never exceed 60 ° C.
In cases where the temperature difference between
the pump and the medium is higher than 30 ° C,
slowly fill / warm the pump to avoid the risk of a
temperature shock.
The operating range depends on the application and a
combination of pressure and temperature.
