. Commissioning
CPA-E and CPA-E S PWM series
.. Before commissioning
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 ).
.. Bleeding the pump
CPA-E circulation pumps are equipped
with a self-bleeding function. It is not
necessary to bleed the pump before
commissioning. Air in the pump can
generate noises. As a remedy, switch
to operating mode III for a short period
of time. The noises will stop after
bleeding. Ensure that the pump is reset
to the required operating mode (see
Chapter ).
The Pump must not run dry.
