conexión eléctrica.
5. Controles previos a la puesta en marcha inicial
Compruebe que la tensión y frecuencia de la red
corresponden a las indicadas en la placa de carac-
terísticas.
Asegúrese de que el eje del motor gire libremente
Llene de agua completamente el cuerpo bomba al
igual que el tubo de aspiración a través del tapón de
cebado, asegurándose de que no exista ninguna
junta o racord con pérdidas.
Compruebe que el sentido de giro del motor coincida
con el indicado en la tapa del ventilador. En los
motores trifásicos, si el sentido de giro es erróneo
invierta dos fases en el cuadro de protección.
LA BOMBA NO DEBE FUNCIONAR NUNCA EN
SECO.

1. General
These instructions are for the correct installation and opti-
mum efficiency of our electric pumps.
These are vertical multicellular centrifugal pumps, compo-
sed of several impellers arranged in series that provide
constant flows and variable pressure heights according to
the number of impellers in the structure. They are desig-
ned to operate with clean water at a maximum temperatu-
re of 35°C.
Top quality materials are used in their construction. They
are subjected to strict control and verified with the grea-
test care.
By correctly following the installaton and operation instruc-
tions and the electrical wiring diagrams, overloads in the
motor will be prevented as will be the consequences of all
types could be derived from these, for which we decline
all responsibility.
2. Installation
The pump should be secured to a solid base by
means of screws through the holes in the support in
order to avoid undesirable noise and vibration.
The pump should be placed as close as possible to
the water level so that the suction height will be as
6. Puesta en marcha
Abra todas las válvulas de compuerta que existan en los
circuitos de aspiración e impulsión.
Compruebe la corriente absorbida y ajuste debidamente
el relé térmico sólo en el caso de la versión trifásica.
Si el motor no funcionara o no extrajera agua procure
descubrir la anomalía a través de la relación de averías
más habituales y sus posibles resoluciones que facilita-
mos en páginas posteriores.
7. Mantenimiento
Nuestras bombas no necesitan de ningún manten-
imiento específico o programado. Se recomienda sin
embargo vaciar el cuerpo bomba durante los perío-
dos de bajas temperaturas o en caso de inactividad
prolongada a través del tapón de purga. Si la inac-
tividad persistiera, debe limpiarse la bomba y
guardarse en lugar seco y ventilado.
small as possible and the load losses will be kept to
a minimum.
Moreover, the unit should be safeguarded from pos-
sible flooding and receive dry ventilation.
3. Pipe Assembly
The suction tube should have a diameter equal to or grea-
ter than that of the intake tapping of the pump, with a mini-
mum upward inclination of 2% to enhance correct blow off.
It is indispensable to install a foot valve submerged at
least 30 cm below the dynamic level of the well to prevent
eddies and the resulting entry of air.
The discharge tube should have a diameter equal to or
greater than that of the discharge tapping of the pump.
Neither the suction tube nor the discharge tube sould rest
on the pump.
When a larger diameter is used for the tubes, they shall
be structured with the respective eccentric cones in the
suction and concentric cones in the discharge.
4. Electrical connection
The electrical installation should have a multiple sep-
aration system with contacts opening at least 3 mm.
The protection of the system should be based on a
differential switch (l fn = 30 ma). The supply cable
should comply with CEE standars (2) or be of type
H07 RN-F as per VDE 0250.
Single-phase motors have built-in thermal protection.
In the case of 3-phase motors, the user should provi-
de the appropriate protection as per the installation
regulations in force.
The diagrams in Fig. (1) simplify correct electrical
connection.
5. Controls Prior to Initial Start-up
Check that the mains voltage and frequency are as
stated on the name plate.
Check that the motor shaft turn freely.
Fill the pump casing with water completely, the same
as the suction tube through the priming cap, verifying
that no joint or connector leaks.
Check that the turning direction of the motor concurs
with that indicated on the fan cover. For 3-phase
motors, if the rotating direction is wrong, invert two
phases on the protection panel.
THE PUMPSHOULD NEVER OPERATE DRY.
