4.2 Start/stop of pump
The pump can be started/stopped in two different
ways:
• Locally on the pump control panel.
• By switching on/off the electricity supply.
4.3 Priming/venting of pump
The pump control panel incorporates a button.
Press this button if the maximum pump capacity is
required over a short period, e.g. during start-up.
When the button is released, the pump automatically
returns to the previous operating mode.
During priming/venting, it is recommended to let the
pump run without a counter pressure or to loosen the
vent valve by giving it a 1/8 to 1/4 turn.
Note: When the buttons and are pressed
simultaneously, the pump can be set to run for a spe-
cific number of seconds at maximum capacity. The
remaining number of seconds will appear in the dis-
play. The maximum value is 300 seconds.
4.4 Indicator lights
The green and red indicator lights on the pump are
used for operating and fault indication.
The functions of the indicator lights appear from the
