Start-up

8.1 Filling and de-aeration

The system must be filled and de-aerated with due care. The
pump rotor space is automatically de-aerated after a short oper-
ating period.

8.2 Setting the pump output

8.2.1 Regulation types

If the pump is operated with regulation type
pump output must be set based on the calculated operating
point. The factory setting does not correspond the pump output
required for the system. It is determined based on the character-
istic curve diagram of the selected pump type (see product infor-
mation). See also Fig. 3.3 Appendix page III and Fig. 3.4 Appen-
dix page III.
8.2.2 Setting the pump output via analogue signal 0...10 V
When the the speed is adjusted using an 0...10 V analogue sig-
nal, the setpoint/actual value comparison required for the regula-
tion is carried out by an external controller. The external control-

Maintenance

Maintenance and repair work must only be carried out by
qualified specialists!
ATTENTION!
WARNING! Danger of electric shock
It must be ensured that there are no risks resulting from electrical energy.
Disconnect the system/pump(s) from the power source and secure it/
them against unauthorised restarting before carrying out any
maintenance or repair work.
ATTENTION!
WARNING! Danger of scalding
Whenthe medium temperatures and system pressures are high, let the
pump cool down and depressurise the system.

WARNING! Danger of burns
Depending on the operating status of the pump or the system
(temperature of the medium to be pumped), the pump can become very
hot.
Touching the pump may cause burns!
The temperature at the heatsink can reach up to 70°C within the
permissible operating condition range.
