10.1. Before start-up
Ensure that the system is filled and the minimum inlet pressure
is applied before you switch on the pump (for more information
please see Chapter ).
10.2. Venting the pump
OEG circulation pumps are equipped with a
self-venting function. It is not necessary to vent
the pump before starting it. Air in the pump can
cause noises. For quick venting, switch to ope-
rating mode III for a short period of time. The
noises will stop after the venting. Ensure that
the pump is reset to the required operating
mode (see Chapter ).
The pump must not run dry.
