Installation
Fill with operating liquid:
When and how the pump-motor unit must be
filled with operating liquid the first time is
dependent on the operating mode:
 For self-priming operation:
During installation.
 For operation with operating-liquid feed:
After completing installation.
For self-priming operation you now pour
operating liquid into the working space of the
pump-motor unit before you connect the
pipes/hoses to the unit.
To do this, pour operating liquid into the open
inlet connection, discharge connection or
operating-liquid port.
For proper filling quantities, see Chapter 4.3,
"Operating conditions", Section "Operating-
liquid filling amount for priming", Pg. 17.
Then attach the pipes/hoses to the unit as
described in the following.
 WARNING
Danger due to gauge pressure
and vacuum!
Danger due to escaping fluid!
During operation, connected
pipes and vessels are
pressurized or vacuumized!
Make sure that all connections
are sufficiently tight! Use only
pipes and vessels of sufficient
strength!
NOTICE
Attach pipes/hoses free of
mechanical tensions.
Support the weight of the
pipes/hoses.
7.3.1 Inlet connection
The inlet connection (Fig. 7, Pg. 25, Item 3) is
marked with an arrow pointing downward (↓).
Connect the inlet pipe here. The pumped
gases/vapors are sucked in via this.
CAUTION
The tightening torque for pipe
connections on intake and
discharge connections may not
exceed 100 Nm [73.8 ft lbs]!
7.3.2 Discharge
connection
The discharge connection (Fig. 7, Pg. 25,
Item 2) is marked with an arrow pointing
upward (↑).
Connect the discharge pipe here. Both the
pumped gases/vapors and the operating liquid
are discharged via this pipe.
CAUTION
The tightening torque for pipe
connections on intake and
discharge connections may not
exceed 100 Nm [73.8 ft lbs]!
7.3.3 Operating-liquid
port
The operating-liquid port (Fig. 7, Pg. 25,
Item 1) is located between the discharge and
inlet connection.
Connect the feed pipe for the operating liquid
here.
