4.3 Venting the pump

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. Still,
we recommend venting the pump in new installations or when the
pipes have been emptied and refilled with water.
Venting the pump at the first startup
When the pump is connected to Grundfos GO Remote, the app
takes you through a setup wizard. See section
.
When the setup is completed, a "Pump venting" dialogue box
appears after approximately two seconds, which guides you
through the pump venting process.
The venting process lasts 30 minutes.
Venting the pump via the "Assist" menu
You access the "Pump venting" menu in the "Assist" menu. Do as
follows:
1. Connect the pump to Grundfos GO Remote. See section
7.2 Connecting the pump to Grundfos GO Remote
2. Go to the "Assist" menu and choose "Pump venting". Follow
the instructions given in Grundfos GO Remote. The venting
process lasts 30 minutes.
