Self-Priming Pump
5
Turn switch 12 to position “I”. The pump will
start (when the tank pressure is below the
pressure switch setting).
Close the shut-off valves in the discharge line
when there is no air in the water
fl
owing out of
the pump.
The pump will build up the required pres-
sure and, after the cut-off pressure has been
reached, it will shut off automatically.
The pump turns on and off automatically - as
the water supply is consumed and when the
tank is
fi
lled.
Note!
The cut-in and cut-out pressures are
preset at the factory and cannot be changed
in the field. Self-adjusting the pressure can
lead to product failure. If cases of self-adjust-
ment are identified, the product is removed
from the warranty. If necessary, additional ad-
justment should be carried out by a specialist.
by the service center.
A thermal switch is installed at your pumping
station to prevent overheating of the pump
electric motor and its failure.
Note!
Periodic shutdown and reclosing of the
station (with constant water consumption) in
the absence of visible malfunctions (extrane-
ous noise, drop in supply pressure, etc.) are
signs that the thermal switch has tripped. This
indicates unfavorable operating conditions:
high temperature of the ambient air or inlet
water; being in direct sunlight; prolonged sig-
ni
fi
cant water consumption, causing the pump
to run continuously.
At the end of use, turn off the station by mov-
ing the switch 12 to the “0” position. Remove
the plug from the socket.
Before long-term storage of the station, com-
pletely empty the tank and pump from water
by draining the water through the nozzle 14.
Attention!
ALWAYS relieve pressure before
disconnecting hoses by turning on the nearest
valve.
Possible problems and malfunc-
tions
The station does not start:
–
There is no mains voltage.
Check cable,
plug, connectors, fuse.
–
Overheating of the engine due to high
temperature of the pumped liquid.
Elim-
inate the cause of overheating and allow
the engine to cool down.
–
Overheating of the engine due to
blocked ventilation openings.
Eliminate
the cause of overheating and allow the en-
gine to cool down.
–
The residual current device has tripped.
Consult a quali
fi
ed electrician if the residu-
al current device trips again.
–
Defective engine.
Contact the service
center.
Insufficient pressure generated by the
pumping station:
–
There is not enough water in the suc-
tion line.
Ensure there is water in the suc-
tion line.
–
The suction line is not tight.
Check all
seals and connections on the suction line.
–
The suction lift is too high.
Reduce the
suction lift. The suction head must be sub-
tracted from the head.
–
Leakage between pump hydraulics and
motor.
Contact the service center.
–
The pump is clogged or defective.
Flush
the hydraulic end of the pump with clean
water.
–
Air in the pump or suction pipe.
Fill the
pump with water. If the suction line has a
non-return valve,
fi
ll it with water.
–
Changed pressure switch settings Con-
tact the service center.
–
The suction line rests against the bot-
tom of the tank.
Fix or shorten the suction
line.
The pump does not turn off:
–
Defective On / Off switch.
Contact the
service center.
Maintenance and Cleaning
►
All maintenance work must be carried
out with the cable disconnected from
the mains.
During operation, the pumping station does
not require any maintenance.
To exclude an accident, it is recommended
from time to time to check the maximum head
and energy consumption, as well as the air
pressure in the accumulator (for this, turn off
the pump and drain the water from the pres-
sure line). A decrease in the maximum head
indicates wear, while an increase in energy
consumption indicates the presence of me-
chanical friction in the pump.
If you
fi
nd these or other changes in the oper-
ation of the pump, contact the service center.
Service
►
Have your power tool repaired only by
quali
fi
ed personnel and only with origi-
nal replacement parts. This ensures the
safety of the power tool.
