Oase ProMax Pressure Automatic 5500/5 Instrucciones De Uso página 17

OPERATION
The pump control system switches the
pump on and off automatically.
• The pump control system (flow control)
measures the flow and switches the
pump off if the water flow stops.
• The pump switches off when there is in-
sufficient water, protecting it from being
damaged by running dry.
• The integrated non-return valve pre-
vents water from flowing back into the
pump from the pressure hose when it is
switched off. The non-return valve also
prevents damage to the pump resulting
from water hammer.
Starting up the pump
W A R N I N G
Dangerous electrical voltage!
Death or severe injury from electrocu-
tion.
• Only connect the pump to the power
supply when there are no persons in or
reaching into the water.
• Before stepping into or reaching into the
water, switch off all units located in the
water.
• Insert the power plug into the socket.
– The pump is ready for operation.
– The pump switches on automatically
when water is used and the pressure
in the pressure line falls below
3.5 bar.
– The pump switches off automatically
when no more water is used and the
maximum pressure in the pressure
line is reached.
N O T E
If the water contains a large quantity of
suspended sand (e.g. in the case of a
new well), allow the pump to run at full
flow rate for approx. 1 hour without inter-
ruption in order to pump out the water
containing the sand. Otherwise the non-
return valve could become blocked by
sand being deposited in the pressure
line.
Taking the pump out of operation
• Disconnect the power plug.
