8Start-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
operating period.
ATTENTION!
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.
8.2 Setting the pump output
8.2.1 Regulation types
If the pump is operated with regulation type p-c or p-v, the
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
characteristic curve diagram of the selected pump type (see
product information). See also Fig. 3.3 Appendix page III and
Fig. 3.4 Appendix page III.
Table 8.1:
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
signal, the setpoint/actual value comparison required for the
regulation is carried out by an external controller. The external
controller provides an analogue signal (0-10 V) to the WILO
Stratos-PARA as a manipulated variable. (Fig. 3.3 Appendix
page III and Fig. 3.4 Appendix page III).
9 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.
