Priming from an open water source
7.4.1 Activate drafting operation from open water source
► Bring the portable fire pump into a good position in relation to the water
source.
Observe the inclination of the engine (max. 35° in the direction of
the suction inlet and operator, and 15° in the direction of the radi-
ator and exhaust).
Do not place the pump on anything flammable (grass, leaves,
straw, etc.).
► Close drain cock (J7).
► Close pressure outlets (J11).
► Connect suction and pressure hoses.
The suction hose with strainer should be under water at least 20
cm (do not place in mud or on sand).
At the drafting point, the drop in water level must be observed.
► Starting the pump engine - see "Starting the engine".
► Ventilate the pump and suction hose.
Automatic priming is activated by briefly pressing the priming
pump function switch (S3). With a pressure of approx. 1.5 bar, the
priming will be automatically completed. The priming pump will
then be run dry.
If the priming process lasts longer than 30 sec. the priming pump
automatically shuts down, a message appears on the display.
► Open the discharge outlets (J10) and increase speed by means of the
governor (S15a) until the desired pressure is reached.
