Supply operation with intake pressure monitoring system (optional)
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".
Activate intake pressure monitoring system
► Actuate caps lock key in the middle of the governor, to activate the au-
tomatic pump pressure governor.
The governor illuminates blue.
The intake pressure monitoring system is activated.
As soon as an intake pressure of 1.5 bar (21 psi) is reached the
intake pressure monitoring system is active.
► If the intake pressure falls back below 1.5 bar (21 psi) the intake pres-
sure monitoring system reduces the discharge pressure.
The discharge pressure is reduced until the intake pressure rises
above 1.5 bar (21 psi) again.
► If the intake pressure suddenly drops below 0 bar (0 psi), the automatic
pump pressure governor and the intake pressure monitoring system
are deactivated.
Deactivation takes place time-delayed.
► The water pump pressure must be controlled manually.
► The automatic pump pressure governor and the intake pressure mon-
itoring system must then be reactivated.
