6.1 Preparations for commissioning
6.1.1 Checking shut-down period
►
Shut-down periods > 1 year: contact the manufacturer and
ask for required measures.
►
Shut-down periods < 1 year: take all steps as required for
commissioning (

Commissioning, page 14).
6.1.2 Filling and venting
1. Fill the aggregate and the suction pipe with the medium to
be pumped and vent.
2. Open the suction-side fitting (if available).
3. Open the pressure-side fitting (if available).
4. Make sure all ports and connections are tight.
6.2 Commissioning
6.2.1 Switch-on

Aggregate correctly set up

Motor connected to the power supply



All safety devices installed and checked for proper function-
ing
DANGER
Risk of injuries caused by running aggregate!
►
Do not touch the running aggregate.
►
Do not carry out any works on the running aggregate.
WARNING
Risk of injuries caused by hot pump parts or hot media to
be pumped!
►
Use protective equipment when carrying out any works on
the aggregate.
CAUTION
Risk of material damage caused by dry running!
►
Make sure the pump has been properly filled.
CAUTION
Risk of cavitation when throttling down the suction flow!
►
Completely open the suction-side fitting and do not use it
for controlling the flow rate.
►
Do not open the pressure-side fitting beyond the operating
point.
CAUTION
Risk of material damage caused by a closed pressure pipe!
►
Do not operate the aggregate when the pressure-side fitting
is closed.
►
Observe the minimum flow rate (

Operating limits,
page 25).
1. Completely open the suction-side fitting (if available).
2. Open the pressure-side fitting (if available).
3. Switch on the motor and provide for a smooth running
behaviour of the aggregate.
4. When the nominal speed has been reached, set the operat-
ing point by means of the pressure-side fitting (if available).
5. After the aggregate has been subjected to pressure and
operating temperature for the first time, check whether it is
tight.
6.2.2 Switch-off
WARNING
Risk of injuries caused by hot pump parts or hot media to
be pumped!
►
Use protective equipment when carrying out any works on
the aggregate.
1. Switch off the motor.
2. Close the pressure-side fitting (if available).
3. Close the suction-side fitting (if available).
4. Check all connecting screws and tighten if required (only
after initial commissioning).
