5.1 Before startup
Do not start the pump until the system has been filled with liquid
and vented. Make sure that the required minimum inlet pressure
is available at the pump inlet. See section 9. Technical data. For
instructions on how to vent the system, see section 5.3 Venting
the pump.
5.2 First startup
After installing the product, see section 3. Installing the product,

5.3 Venting the pump
Fig. 8 Venting the pump
The pump is self-venting through the system. You do not have to
vent the pump before startup.
Air in the pump may cause noise. This noise ceases when the
pump has run for a few minutes.
You obtain quick venting of the pump by setting the pump to
speed III. How fast the pump is vented depends on the system
size and design.
When you have vented the pump, i.e. when the noise has
ceased, set the pump according to the recommendations. See
section 7. Control functions.
You cannot vent the system through the pump. See section
6. Product introduction.
