1. Open the screw plug of the vent hole1 by a max. of 2 rotations so that air can escape during the
filling process.
2. Open the suction-side or pressure-side shut-off device and fill the pump via the suction connec-
tion or pressure connection until pumped liquid is emitted at the vent hole1.
3. During the filling process turn the pump shaft or the fan impeller of the motor by hand to speed up
the filling process:
Filling via suction connection: Turn the fan pump shaft in the direction of rotation of the motor.
