8 Commissioning

Do not fail to observe the danger information and warnings in
Chapters 7, 8.5 and 9!
Prior to commissioning the pump, check that it was installed and connected
correctly.

8.1 Filling and Venting

• Proper fill and pressurize the system with liquid.
CAUTION! Possible damage of the pump!
Never operate the pump dry.
The system must be filled before starting the pump. Ensure that all isolation
valves are open.
• The pump is normally vented automatically after a short operational period.
WARNING! Risk of burning!
Depending on the operating condition of the pump and/or installation (fluid
temperature) the entire pump can become very hot.
Avoid touching the pump owing to the risk of burning.
The temperature at the heat sink can be up to 158°F (+70°C) within the
permissible operating conditions.

8.2 Setting the menu

WARNING! Risk of burns!
Depending on the operating status of the system, the entire pump can
become very hot. There is a risk of burns if metallic surfaces are touched (i.e.
cooling fins, motor housing, pump housing).
The setting can be made on the control module during normal operation by
pressing the control button. Do not touch any hot surfaces when doing this.
8.2.1 Using the control button (fig. 1, pos. 1.3)
• From the basic setting, the setting menus are selected one after another by
pressing the button (press longer than 1 second for the first menu). The current
symbol flashes. The parameters can be moved backwards or forwards on the
display by turning the button clockwise or anti-clockwise. The newly set symbol
flashes. The new setting is applied and the next setting option is activated by
pressing the button.
• The setpoint (differential pressure or speed) is changed in the basic setting by
turning the control button. The new value flashes. The new setpoint is saved by
pressing the button.
• The old value is retained and the basic setting is displayed again if the new
setting is not confirmed within 30 seconds.
