7.3 Venting the pump
TM077002
Venting the pump
Small air pockets trapped inside the pump may cause noise when
starting up the pump. However, because the pump is self-venting
through the system, the noise ceases over a period of time.
To speed up the venting process, do as follows:
1.
Set the pump to speed III using the button on the operating
panel.
2. Let the pump run for minimum 30 minutes. How fast the pump
is vented depends on the system size and design.
When you have vented the pump, that is when the noise has
ceased, set the pump according to the recommendations.
The pump must not run dry.
The pump is from the factory set to constant curve 3.
