8.2 Dangers during removal
The following safety instructions must be observed strictly:
o Have all work carried out only by authorized qualified personnel.
o
Before beginning work, let the pump unit cool down to the ambient temperature.
o
Collect any discharging pumped liquid safely and dispose of it in an environmentally compatible
manner in accordance with the applicable local regulations.
o
Ensure that the collection tank for discharging pumped liquids is sufficiently large.
8.3 Mounting the pump station
The pump station is operated in a vertical installation position.
Notice Soiling in the pipe system impairs the service life of the pump station. If the pipe system is flushed us-
ing the pump station during the initial commissioning, an additional commissioning filter has to be in-
stalled temporarily before the pump station. Alternatively the strainers supplied as standard can be re-
placed during commissioning by fine-meshed commissioning strainers.
