MOTOR WOULD NOT START
False contact in the installation or in the motor
connection. Verify that all the connections are
well done. If not, do them again and protect
them correctly.
Loose, broken or incorrect wires. Verify the
wiring, if correct, connect it again, tighten the
connections and replace defective wires.
Burnt fuses or thermomagnetic switch tripped.
Replace the fuses or close the switch. Make sure
that the size of the fuses is correct according to
the current consumption of the motor. Verify
there is no short circuit in the motor line.
Defective start-up device. Replace it if damaged
or if not appropriate for the size of the motor.
Motor shaft or other elements rotate stuck.
Verify there are no objects preventing the free
motion of the rotor, shaft or impeller.
Check that the bearings are in good condition.
Motor coil burnt. Visit an authorized service
workshop.
THE MOTOR TURNS ON AND OFF CONTINU-
OUSLY
Low voltage in the line. Verify that the wire
used is appropriate. Install a voltage regulator
or check it with the electrical supply company.
Very small range in pressure switch level floata-
tion tank. Adjust your (level or pressure) switch
so that your motor pump starts on the few-
est times possible even if it is for long periods.
Check your floating tank.
Water leak in piping. Check and seal any type of
leak.
Foot or check valve in bad condition. Verify it
seals properly. Replace it if necessary.
THE PUMP DOES NOT SUPPLY WATER (or sup-
plies very little water)
The pump is not primed, the impeller is dam-
aged or the foot valve is defective. Fill up your
pump and suction piping with water, using the
hole made for this purpose through the dis-
charge tee.
Closed valve or blocked piping in the suction or
discharge line. Open the valves that prevent the
flowing of water and clean or replace blocked
piping. Check that the foot valve is not stuck.
Air enters the suction piping. Verify that the
piping and connections are in good condition.
Use some type of sealant in connections.
Excessive height of the suction (maximum 5 m).
Get your pump the closest possible to the water
mirror, without exposing it to possibly get wet.
M a n u a l d e u s u a r i o • U s e r 's m a n u a l
The piping is worn or its diameter is very little
(too much friction). Replace worn or inappropri-
ate piping and install new pipes or with wider
diameter.
The pump works at fewer revolutions that indi-
cated. Verify that the connections are well done
and that the impeller turns in the correct direc-
tion; verify the operating voltage of the pump,
or the amperage of the pump while function-
ing.
The impeller is blocked by impurities. Open the
impeller and install a strainer or screen in suc-
tion if necessary. (In non-self-priming pumps do
not remove the strainer check valve).
Discharged pump. A bad quality strainer check
valve causes water leaks and causes the load is
lost.
Dirty strainer. Open the strainer container, clean
it and put it back in place.
NOISY MOTOR PUMP
The suction valve is closed, the foot valve is
stuck or the pump is inappropriate. Open the
valve or remove anything that is preventing the
water from easily flowing by suction, verify that
the diameter of the piping for suction is correct.
Very low discharge pressure. If you wish to re-
duce the noise, close the discharge valve a little.
The impeller is brushing in the pipes or in the
body of the pump. If the suction piping screws
more than what is appropriate, it may brush
against the impeller. Loosen it and then apply
connection sealant and screw it again up to it
can be done.
Damaged bearings. Replace the damaged bear-
ings and make sure they are well adjusted.
IMPORTANT: If you are unable to correct a
fault yourself, please contact our technical sup-
port directly. Please note that improperly con-
ducted repairs will void your warranty and may
cause you additional expenses.
