Operation
7.6.6 Supply operation/hydrant 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.

NOTICE
Damage to the pump in the event of use with waste water!
Waste water can damage the pump unit through deposits.
Before connecting the pressure hoses to hydrants, open them and
allow water to escape until only clean water flows out.
► Position the portable pump.
Refer to chapter "Position the portable pump".
► Connect pressure hoses to the pressure outlets.
► Connect pressure hoses from the hydrant or the supply line to the ex-
ternal drafting water connection.
► Open at least one pressure outlet, to remove pressure peaks.
► Slowly open hydrant valve.
► When the water reaches the pump, switch on portable pump.
Refer to chapter "Start portable pump".
► Open pressure outlets.
Refer to chapter "Open/close discharge pipes".
► Set pump pressure to desired value.
Refer to chapter "Adjust water pump pressure".
