DECOMMISSIONING/DISPOSAL English
6.1. Commissioning
CAUTION!
Contaminants and solids, as well as improper commissioning, can
lead to damage to the pumping station or individual components
during operation.
• Before commissioning, clean the entire pumping station of con-
taminants, particularly solids.
• Observe the installation and operating instructions for the pump,
switchgear, level control device and other accessories.
NOTE:
At sustained outside temperatures below 0 °C, particularly if use is
restricted or suspended, there is a risk of frost in the pump cham
-
ber due to insufficient water exchange.
• In this case, appropriate insulation measures must be taken in the
area above the pump cover.
• If the pump chamber is not to be operated at all, we recommend
completely draining the pump chamber and pressure pipe.
Commissioning may only be carried out if the system has been
installed in accordance with these installation and operating in-
structions and the installation and operating instructions for the
individual components, and all protective measures are effective and
the applicable safety regulations, VDE regulations and any regional
regulations are met.
Check that all required components and connections (inlet, dis-
charge pipe with shut-off device, venting, electrical connection) are
present and properly installed.
1. Open the pump cover.
2.
Completely open the shut-off device. If the handle of the shut-off
device is not easily accessible, an operating crank is available as an
accessory.
3. Check that the pump and piping are installed securely and pressure
tight.
4.
Set the switchgear to ‘automatic mode’
5.
Fill the system using the connected inlet.
6.
Function test: Observe at least two on/off cycles and check that
the pump is functioning properly and the switching points are set
correctly.
If backing up occurs in the inlet pipe, the switching points should
be corrected accordingly.
7. When the function test has been completed successfully, install the
pump cover and check that it is fitted securely.
8. The system is now operational.
6.2. Behaviour during operation
The pump cover must be fitted during operation of the pumping
station. No personnel may be present in the pump chamber.
7. Decommissioning/disposal
• The system must be decommissioned for maintenance work or
dismantling.
• When the pump chamber is open, the working area must be marked
accordingly and cordoned off. There is a risk of falling.
•
Technically sound lifting equipment and officially approved lifting
gear must be used to lift and lower the installed pump.
