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
NOTE: Incomplete venting will result in noises in the pump and unit.
Prime and vent the unit correctly. Venting the pump rotor compartment is car-
ried out automatically after a short operating period. Dry running for short peri-
ods will not harm the pump.
WARNING! Risk of injury and damage to property!
It is not permitted to remove the motor head or the flange connection /
threaded pipe union for the purpose of venting the system!
• There is a risk of scalding!
Escaping fluid can lead to injuries and damage to property.
• Touching the pump can cause burns! Depending on the operating status of
the pump or unit (fluid temperature), the entire pump can become very hot.
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 (e.g.
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. 1a, item 1.3)
• Starting with the basic setting, by pressing the button (for the 1st menu: press-
ing it longer than 1 second), the setting menus are selected in succession in a
defined sequence. The corresponding symbol flashes. By turning the button to
the left or right, the parameters can be changed backwards or forwards on the
display. The newly set symbol flashes. The new setting is saved by pressing the
button. Then, the next selection option appears.
• The basic setpoint setting (differential pressure or speed) is changed by turning
the control button. The new value flashes. The new setpoint is saved by press-
ing the button.
• The old value is retained and the basic setting is displayed again if the new set-
ting is not confirmed within 30 seconds.
