Check connections of the pipes/hoses for
leaks.
Check direction of rotation:
 The direction of flow of the pumped
gases/vapors is marked with arrows on the
intake and discharge connection.
 The intended direction of shaft rotation is
marked with an arrow on the motor
mounting adapter between the intake and
discharge connection, as well as with an
arrow on the fan guard.
 The pump-motor unit may not be allowed to
run dry!
Have you filled it with operating liquid
beforehand (during or after installation)?
See sections "Fill with operating liquid",
Pg. 26 and Pg. 28.
 Briefly switch on pump-motor unit.
 Compare the actual direction of rotation of
the external fan with the intended direction
of shaft rotation as indicated with the
arrows.
 Switch off pump-motor unit again.
 If necessary, reverse the direction of
rotation of the motor.
