MAINTENANCE

- The pump does not require maintenance as
long as the following precautions are taken:
when there is a risk of freezing, empty the
pump by removing the suction tube, ensur-
ing that the pump is primed when it is started
again, check that the foot valve is cleaned at
regular intervals, if the pump is to remain inac-
tive for an extended period of time it is advis-
able empty it completely, rinse it with clean
water and store it in a dry place. if the arrow
does not turn freely, release it using a screw-
driver, there is a hole in the back of the pump
that gives access to the arrow, turn it with the
help of the screwdriver, if this does not solve
the problem remove the pump body, by loos-
ening the corresponding mounting screws and
clean it perfectly to remove any incrustation.
NEVER CARRY OUT WORK ON THE PUMP
WITHOUT FIRST DISCONNECTING IT FROM
THE MAINS.- TO IDENTIFY WHERE THE WATER
LEAKS ARE, DRY THE MOTOR PUMP AND PIP-
ING AND FILL IT UP AGAIN WITH WATER.
- Below you will find a box with the problems
that may arise.
- If you find any failure in your motor pump,
even out of the Guarantee term or if you
needed to repair the product by yourself, we
remind you that we have authorized service
shops.
CONSIDERATIONS TO INSTALL THE WATER
TANK
It is recommended to install a foot valve with
a diameter wider than the pump´s suction to
avoid losses due to friction.

THE PUPM SPILLS WATER
Loose or badly sealed pipes. Identify the
place of the leak and use some type of sealant
(SURTEK threads sealer tape, Cement, Pola,
®
etc.) When doing the connections again.
Damaged coupling seal and/or loose screws.
Replace the damaged parts and securely tight-
en the screws, being careful not to strip them.
Defective mechanical seal. Replace the dam-
aged parts and assembly again your motor
pump making sure no part is loose.
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 accord-
ing to the current consumption of the motor.
Verify there is no short circuit in the motor line.
Defective start-up device. Replace it if dam-
aged 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 floa-
tation tank. Adjust your (level or pressure)
switch so that your motor pump starts on the
fewest times possible even if it is for long peri-
ods. 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-
