Operation
The highest pressure of the water pump, read from the pressure gauge, is
17 bar (246 psi). The maximum feed pressure (supply pressure), read on
the pressure vacuum gauge, is 17 bar (246 psi).
The supply pressure, read on the pressure vacuum gauge, must not drop
below 1 to 2 bar (15 to 30 psi), otherwise a cross-sectional constriction of
the hose will occur and the water supply will be interrupted.
If the limit pressure of 17 bar (246 psi) is exceeded during operation, the
portable pump automatically reduces the engine speed and thus the pump
pressure. The discharge pressure is limited to maximum 17 bar (246 psi).
This prevents the hose from bursting. If the discharge pressure drops
again, the speed is again increased automatically.
Due to the electronic control, it is possible to exceed the limit pressure for
a short time.
External drafting
Activate external drafting
► Position the portable pump.
Refer to chapter "Position the portable pump".
►Close drain valve.
► Close pressure outlets.
Refer to chapter "Open/close discharge pipes".
► Connect pressure hoses to the pressure outlets.
► Connect pressure hoses to the external drafting water connection.
Note the drop in water level at the drafting point.
► Switch on portable pump.
Refer to chapter "Start portable pump".
► Actuate the Priming pump function switch to ventilate the portable
pump and the suction pipe.
Priming pump is activated.
The priming process is automatically completed at a pump pres-
sure of approx. 1.5 bar (21 psi).
If the function switch remains activated, the priming pump is auto-
matically reactivated if the water column breaks or the pump pres-
sure is below 1.5 bar (21 psi).
If the priming process takes longer than 30 seconds, the priming
process is automatically deactivated and a message appears on
the screen.
Priming pump is activated.
External drafting operation is started.
► Open pressure outlets.
Refer to chapter "Open/close discharge pipes".
► Set pump pressure to desired value.
Refer to chapter "Adjust water pump pressure".
