Pumped liquids can be hot, poisonous, combustible and caustic.
► Wear personal protective clothing during all the work. Ensure face protection.
► Collect any discharging pumped liquid safely and dispose of it in an environmentally compatible
manner in accordance with the applicable local regulations.
ATTENTION
Dry running can damage pump equipment.
► Ensure that the pump and the connected pipe system are filled properly.
► If the pump does not deliver after 10 – 15 seconds, abort commissioning.

1.
Switch on the pump station.
ð
The pump station delivers when the pressure on the pressure side of the pump station rises.
2.

Troubleshooting, Page 33.
3.
Run the pump station for a few minutes to allow the pipe system to vent fully.
ð
The pipe system is fully vented when there is a smooth operating noise and a pressure gauge
on the pressure side of the pump shows no more fluctuations.
