Damage to equipment through additional pressure loss in the commissioning filter/commis-
sioning strainer.
► Calculate the flow resistance and determine the remaining pump intake.
► Monitor the suction-side pressure.
► Check the commissioning filter/commissioning strainer regularly.
Requirement:
ü
If required, commissioning filter installed (mesh width 0.02 mm)
1.
Clean the complete pipe system before commissioning in order to protect the pump.

DANGER
Risk of death through emitted pumped liquid.
Pumped liquids can be hot, poisonous, combustible and caustic and can spray out under high pres-
sure.
► Wear personal protective equipment during all the work. Ensure face protection.
► Collect any discharging pumped liquid safely and dispose of it in an environmentally compatible
manner in accordance with the applicable local regulations.
ATTENTION
Dry running can damage pump equipment.
► Ensure that the pump is filled properly.
1.
Before commissioning fill the piping and pump via the suction connection with pumped liquid, for
example via a tank that is positioned higher.
2.
During the filling process turn the pump shaft or the fan impeller of the motor by hand in the direc-
tion of rotation of the motor in order to speed up the filling process.
10.2.3
Checking the direction of rotation
The direction of rotation is indicated by an arrow on the pump flange. The direction of rotation of the
motor specifies the direction of rotation of the pump. The fan impeller of the motor must rotate in the
same direction in which the arrow for the direction of rotation on the pump flange points.
Notice
Standard direction of rotation: clockwise (viewed from the motor)
