Espa Acuaria 57 [2/20] Instruction manual
2
En los motores monofásicos debe conectar el conden-
sador junto con el cuadro de protección al exterior del
pozo.
La protección térmica debe ser suministrada por el
usuario (de acuerdo a las normativas de la instalación
vigentes).
Para una correcta conexión eléctrica, siga los esque-
mas de la FIG. 3 o FIG. 4.
5.
Controles previos antes de la primera puesta en marcha
Compruebe que la tensión y la frecuencia de la red corres-
ponde con la indicada en la placa de características.
Asegúrese de que el valor del condensador sea igual al
descrito en la placa (sólo versión monofásica).
Controle que la bomba esté totalmente sumergida. Si el
caudal es menor al esperado, invierta dos fases de la alimen-
tación en el cuadro de protección (sólo versión trifásica).
LA BOMBA NO DEBE FUNCIONAR NUNCA EN SECO.
6. Puesta en marcha
Si existe alguna válvula de compuerta, ábrala total-
mente. Conecte el interruptor de suministro eléctrico;
en ningún caso el agua manará al final de la tubería al
momento; si el recorrido es considerable, espere unos
minutos.
Verifique que la corriente absorbida sea como la
marcada en la placa de características y ajuste el relé
térmico debidamente (sólo en la versión trifásica).
Si el motor no arranca o no brota agua al final de la
tubería, procure descubrir la anomalía a través de la
relación de averías más habituales y sus posibles
soluciones que facilitamos.
7. Mantenimiento
Las bombas serie ACUARIA están exentas de mante-
nimiento. En épocas de heladas, tenga la precaución
de vaciar la tubería.
Si la inactividad de la bomba va a ser prolongada, es
conveniente que se saque del pozo y se guarde en un
lugar seco y ventilado.
ATENCIÓN: Si debe sustituirse el cable de alimenta-
ción, se necesitan herramientas especiales, esta opera-
ción sólo puede realizarse en fábrica o en Servicios
Oficiales Autorizados.
Llegado el momento de desechar la bomba, esta no
contiene ningún material tóxico ni contaminante. Los
componentes principales están debidamente identifi-
cados para poder proceder a un desguace selectivo.

words “Danger” or “Warning” indicates the risk level deriving
from failure to observe the prescribed safety precautions:

WARNING
1. General information
The following instructions will help you to achieve a good pump
performance and an easy installation without problems.
Read all instructions thoroughly.
The ACUARIA series is a vertical submersible pump
providing trouble free installation, completely manufactured in
stainless material except the lower and upper supports which
are in grey cast iron.
Conceived to operate with clear water, free of particles in
suspension, at a maximum temperature of 35
o
C.
All pumps have been manufactured in first quality material
submitted to strict hydraulic and electric controls and care-
fully verified.
For a correct installation, follow the directions in the given
electrical schematic chart and the operating and mainte-
nance instructions. Failure to do this could result in motor
over-loading and other material or bodily damage on which
we decline all responsibility.
2. Installation
The pump should not rest on the bottom of the well or
be too near the walls. This can be avoided by
suspending the pump by a cable hooked to the handle
on top of the pump.
Never suspend pump by its electric cable or by the
discharge pipe. Pump must always be totally submerged
which will provide it with the necessary cooling.
Make sure that the volume of flow in the well is bigger
than needed to prevent pump from running dry or from
starting and stopping at higher frequency than normal.
If the water level in the well has large fluctuations, it is
recommended to install a level control switch.
Fix electric cable and level control switch cable to the
discharge pipe with clamps in order to avoid any
damage when handling pump.
3. Assembly of discharge pipe
The pumps are to be connected to a 1
1/2
” pipe, however in
the case of considerable geometric head and long and
sinuous pipes, it is recommended to use a pipe with a larger
diameter to reduce as much as possible the loss of head by
friction and obtain the best possible hydraulic performance.
Install a check valve to the outlet of the pump and you will
prevent from emptying each time pump stops.
If you choose a plastic pipe instead of a metal pipe, make sure
that it can resist the pressure produced by the pump.
Never let pipe bend over as, apart from not providing the
desired flow, it would obstruct the normal pump operation.
4. Electrical connection
The pump should be installed with a differential switch
(1 fn = 30 mA). The installation should have a switch
with contact openings of at least 3 mm. Pumps are
supplied with electric cable and plug.
To extend electric cable only use resin cable joints.
Make sure that cable colours of the pump coincide with
extension cable colours.
Connection of the yellow-green earth cable is absolutely
imperative.
Thermal protection must be supplied by the user
(according to valid installation regulations).
For a correct electrical connection, follow the instructions
on FIG. 3 and FIG. 4.
5. Control prior initial starting
Verify that the voltage and frecuency of the supply corre-
spond to the values marked on the technical label.
Make sure that the value of the capacitor is the same as that
described on the label (only single phase versions).
Check that the pump is completely submerged.
Warns that failure to observe the
precautions involves the risk of dama-
ging the pump and/or the plant.
Warns that failure to observe the
precautions involves a risk of damage
to persons and/or things.
Warns that failure to observe the
precautions involves a risk of elec-
tric shock.
