5.4. Commissioning
This chapter contains all important instructions for oper-
ating personnel for safe commissioning and operation of
the machinery. The following must be complied with and
checked:
•
Type of installation
•
Operation mode
•
Minimal submersion in water / maximum submersion
depth
After a longer downtime these points must also be
checked and detected defaults must be repaired!
The operation and maintenance manual must al-
ways be kept with the machinery, or in a dedicated
place where it is accessible for the entire operating
personnel.
The following points must be taken into account to avoid
personal and material damage when troubleshooting
machinery failures:

5.5. Preparatory work
The machinery was constructed and fitted according to
the latest technology, so that it works for a long time and
reliably under normal operating conditions. This requires
however that you comply with all requirements and infor-
mations. Small oil leakages of the floating ring seals on
delivery are not problematic, but they must be removed
before lowering/immersion into the medium.

5.6. Electrical system
The respective local and VDE regulations must be com-
plied with when choosing and installing the electrical
leads as well as connecting the motor. The motor must be
protected with a circuit breaker. The motor must be con-
nected according to the wiring diagram. Note the direction
of rotation! In the event of wrong direction of rotation the
machine does not perform as indicated and it can become
damaged under unfavourable circumstances.
Check the operating voltage and ensure the equal power
consumption of all phases according to the machine data
sheet.
Ensure that all temperature sensors and monitoring de-
vices, e.g. sealing chamber control, are connected and
tested for functionality.
The commissioning of the machinery must only be
carried out by qualified and trained personnel in com-
pliance with the safety regulations.
All personnel that is working on the machinery must
have received, read and understood the operating in-
structions.
Activate all safety equipment and emergency switch-
offs before commissioning.
Electrotechnical and mechanical settings must only
be carried out by specialists.
This machinery is only suitable for the use under the
indicated operating conditions.
Cable run - no loops, slightly tightened
Check temperature of the medium and submersion
depth - see machinery data sheet
If a tube is used for pressure, this must be rinsed with
clear water so that no deposits lead to obstruction.
The pump pit must be cleaned for wet installation
The pressure-sided and suction-sided pipework sys-
tem must be cleaned and all gate valves must be
opened
The pump casing must be flooded, e.g. it must be
filled completely with the medium and it must not
contain an air. The de-aeration can be carried out by
means of suitable venting devices in the system or, if
available, by air-vent screws on the pressure socket.
Check accessories, pipework, suspension devices for
firm and correct fitting
Check available level controls/protection against dry
run
Before commissioning, an insulation test and a fill lev-
el check must be carried out.
