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.
