6.5 Startup
Minor oil leakage in the mechanical shaft seal on deliv-
ery is no cause for concern. However, it must be
removed prior to submersion in the pumped liquid.
Keep out of the work area of the unit. No per-
sons are allowed in the work area during switch-
ing 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 isolation check must be carried out
according to the “Maintenance” chapter.
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 pro-
tection 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
submersion 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
completely full of fluid, with no air in it at all. Bleeding
can be carried 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 sus-
pension unit are properly fitted
• Check all level control and dry-run protection systems
6.5.2 Operation
Products are switched on and off using the plug or
switching device (when available).
On products with float switches, the plug or switching
device is used to switch between manual and auto-
matic mode.
Switching on and off manually (manual mode)
• To switch on, set the switch on the plug or switching
device to ON or I.
• To switch off, set the switch on the plug or switching
device to OFF or 0.
Switching on and off automatically using the level
control (automatic mode)
• To switch on automatic mode, set the switch on the
plug or switching device to AUTO.
• To switch off automatic mode, set the switch on the
plug or switching device to OFF or 0.
Automatic mode only works correctly when a float
switch is connected. The activation and deactivation
points are specified by the level control.
6.5.3 After starting up
The rated current is briefly exceeded during the start-
up procedure. Once the start-up procedure has com-
pleted, the operating 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.
6.6 Safety rules during operation
When operating the product, always follow the locally
applicable laws and regulations for work safety, acci-
dent prevention and handling electrical machinery. To
help to ensure safe working practice, the responsibili-
ties 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.
The following must be checked at regular intervals:
• Operating voltage (permissible dev/- 5 % of
the rated voltage)
• Frequency (permissible dev/- 2 % of the
rated frequency)
• 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
Risk of fatal injury due to explosion!
Products without ex-labeling are not ex-
approved and may not be used in explosion haz-
ard areas! All accessories (incl. attached switch-
ing device/plugs) must be approved for use in
explosion hazard areas!
Siphoning operation is strictly forbidden in
explosion hazard areas! The hydraulic housing
must always be completely filled with fluid!
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 founda-
tion and that the pump pedestal is mounted cor-
rectly.
Beware of rotating parts!
The rotating parts can crush and sever limbs.
Never reach into the hydraulics or the moving
parts during operation. Switch off the product
and let the moving parts come to a stop before
maintenance or repair work!
