Risk of fatal injury due to explosion!
Products without ex-labeling are not ex-
approved and may not be used in explosion
hazard areas! All accessories (incl. attached
switching device/plugs) must be approved
for use in explosion hazard areas.
In order to achieve adequate cooling, units without
active cooling must be flooded completely before
switching on again.

Startup
Minor oil leakage in the mechanical shaft seal on delivery is no
cause for concern. However, it must be removed prior to sub-
mersion in the pumped liquid.
Keep out of the work area of the unit. No persons are
allowed in the work area during switching on and/or
during operation.
Before switching on for the first time, the installation must be
checked as described in the "Installation" chapter and an isola-
tion check must be carried out according to the "Maintenance"
chapter.
Beware of serious injuries.
In portable installations, the unit can fall over
when it is switched on or during operation.
Make sure that the unit is positioned on a
firm foundation and that the pump pedestal
is mounted correctly.
If the unit falls over, it must be switched off before setting it up
again.
In the case of versions with CEE plugs, note the IP protection
class of the plug.
6.5.1 Before switching on
Check the following:
- Cable guidance – no loops, slightly taut
- Check the temperature of the pumped liquid and the submer-
sion depth – see technical data
- If a hose is used on the discharge side, it should be flushed
out with clean water before use to prevent any sediment
causing blockages
- Clean coarse deposits from the pump sump
- Clean the pipe systems on the discharge and intake sides
- Open all sliders on the discharge and intake sides
- The hydraulic housing must be flooded, i.e. it should be com-
pletely full of fluid, with no air in it at all. Bleeding can be car-
ried out using a suitable bleeding device in the system, or, if
available, with bleeder screws on the discharge port.
- Check that all accessories, the pipe system and suspension
unit are properly fitted
- Check all level control and dry-run protection systems
6.5.2 After starting up
The rated current is briefly exceeded during the start-up proce-
dure. Once the start-up procedure has completed, the operat-
ing current may no longer exceed the rated current.
If the motor does not start immediately after the unit is switched
on, it must be switched off without delay. The start pauses
specified in the "Technical data" chapter must be adhered to
before starting up again. If the fault recurs, the unit must be
switched off again immediately. The unit may only be restarted,
once the fault has been rectified.

Safety rules during operation
When operating the product, always follow the locally applica-
ble laws and regulations for work safety, accident prevention
and handling electrical machinery. To help to ensure safe work-
ing practice, the responsibilities of employees should be clearly
set out by the owner. All personnel are responsible for ensuring
that regulations are observed.
The product has moving parts. During operation, these parts
turn to pump the fluid. Certain materials in the pumped fluid can
cause very sharp edges to form on the moving parts.
Beware of rotating parts!
The rotating parts can crush and sever limbs.
Never reach into the hydraulics or the mov-
ing parts during operation. Switch off the
product and let the moving parts come to a
stop before maintenance or repair work!
The following must be checked at regular intervals:
- Operating voltage (permissible deviation +/- 5 % of the
rated voltage)
- Frequency (permissible deviation +/- 2 % of the rated fre-
quency)
- Current consumption (permissible deviation between
phases is a maximum of 5 %)
- Voltage difference between the individual phases (max.
1 %)
- Starts and stops per hour (see technical data)
- Air entry in the intake, a deflector plate should be fitted if
necessary
- Minimum water immersion level, level control unit, dry-run
protection
- Smooth running
- Shut-off valves in the intake and discharge pipes must be
open

All work must be carried out with the greatest care.
Proper protective clothing must be worn.
When carrying out work in basins and/or containers, the
respective local protection measures must be observed in all
cases. A second person must be present for safety reasons.
Only hoisting gear that is in a technically perfect condition and
load-carrying equipment that has been officially approved may
be used for lowering and raising the product.
Risk of fatal injury due to malfunctions!
Load-carrying equipment and hoisting gear
must be in a perfect technical condition.
Work may only commence if the hoisting
gear has been checked and found to be in
perfect working order. If it is not inspected,
danger to personnel may result!
7.1
Temporary shutdown
For this type of shutdown, the product remains installed and is
not cut off from the electricity supply. For temporary shutdown,
the product must remain completely submerged so that it is
protected from frost and ice. Ensure that the temperature of the
