cles the pump switches on not at the switch-on
pressure, but rather waits approx. 25 seconds to
see if the pressure in the system drops to 1.5 bar.
If the pressure does not drop in this time, the air
filling is OK.
Rectification
Check fuses and power supply.
Submerge the end of the suction line into
the water by min. 30 cm.
Remove dirt from the suction area and filter.
Open the closing off devices in the pressure
line.
Check all the connections in the suction line
for leaks.
Replace seal ring.
Switch pump off and allow to cool.
Replace the pressure hose with one with a
larger diameter.
Throttle back the pump to adapt the flow
rate.
Top up the air in the storage vessel. (Set the
diaphragm pressure to 1.5 bar).
