6.1 Commissioning
NOTICE
The pump/unit can be damaged if it runs dry!
Ensure that the pump/unit is always full of water. This also applies to checking the rotation
direction.
6.1.1 Pre-requisites for commissioning
•
Electrical connection is available.
•
Pump/unit is filled with pumped fluid.
•
Pump/unit is positioned correctly.
•
Additional connections are assembled and working.
•
Before commissioning turn the shaft by hand and check for smooth running.
•
Ensure that all preservatives are completely removed from the wetted parts. If necessary
disassemble the pump and clean the parts individually.
–
Pumps with thrust bearing housing:
• Axial clearance between thrust bearing housing and motor shaft is set correctly.
• Thrust bearing housing is lubricated – for design with grease nipples.
6.1.2 Filling pump/unit with pumped fluid and ventilating
NOTICE
The pump can be damaged if it runs dry!
Shut-off valves may
not
be closed during the filling procedure.
Ensure that the pump/unit is always full of water.
Filling up with an open or closed circulation system with sufficient supply pressure (intake mode)

1. Close the shut-off valves (A and B) in the suction and pressure lines.
2. Open the filling plug (C).
3. Open the shut-off valve in the suction line (A) gradually until the pumped fluid flows out of the filling
plug (C).
4. Spin the pump shaft over the motor shaft (impeller fan) several times when filling.
5. Close the filling plug (C).
6. Open the shut-off valves (A and B) in the suction and pressure lines.
Pay attention to the pump’s correct direction of rotation.
