5.4. Initial operation
This chapter contains all the important instructions for op-
erating personnel for the safe commissioning and opera-
tion of the machine. The following information must be
strictly adhered to and checked:
•
Type of installation
•
Operating mode
•
Minimum/max water coverage. Immersion depth
After a long downtime, these specifications are also
to be checked and any defects are to be rectified! The
operation and maintenance manual must always be
kept with the machine, or be kept in a designated place
where it is always accessible for all of the operating
personnel.
To avoid injury to persons or damage during operation of
the machine, the following points must be observed:
The initial operation may only be carried out by
qualified and trained personnel following the safety
instructions.
•
All staff working on the machine must receive, read,
and understand the instructions.

•
Activate all safety devices and emergency stop
switches before initial operation.
•
Electrical and mechanical adjustments may only be
performed by professionals.
•
This machine is only suitable for use at the specified
operating conditions.
5.5. Preparatory work
The machine has been using state of the art technology
and has been constructed so that it will operate reliably
and for long periods under normal operating conditions.
This requires, however, that you comply with all advice
and instructions. Small oil leaks from the mechanical
seal during operation are harmless, however, must be re-
moved before lowering or immersion into the pumping
medium.
Please check the following points:
•
Cable routing - no loops, slightly taut
•
Liquid temperature and immersion depth check - see
machine data sheet
•
If a hose is used on the discharge side, it should be
flushed before use with fresh water so that no depos-
its cause blockages
•
For wet installation, the sump pump must be cleaned
•
The pressure and suction side pipe systems are to be
clean and all slides are to be opened.
•
The pump casing must be flooded, i.e. it must be
completely filled with the medium and there may be
no more air in it. The venting can be done by suitable
ventilation devices in the system, or, if available, by
venting screws at the outlet nozzle.
•
Check the accessories, pipe system and suspension
unit for firm and correct fit
•
Review the present level control or dry run protection
An insulation test and a level control must be
carried out before commissioning.
5.6. Electrical
When installing and selection of electric lines and when
connecting the motor, the relevant local and VDE regu-
lations must be observed. The motor must be protected
by a motor protection circuit breaker. Connect the motor
connect as per the wiring diagram. Pay attention to the
direction of rotation! If rotation is in the wrong direction,
the machine will perform to specifications, and can be
damaged under adverse circumstances.
Check the operating voltage, and ensure there is uniform
power consumption by all phases in accordance with the
machine data sheet.
Make sure that all temperature sensors and monitoring
devices, e.g. sealing chamber control, are connected and
tested for function.
Risk of electrocution!
Improper use of electricity can be fatal! All pumps
with exposed cable ends must be connected by a
qualified electrician.
