Mains Connection - Neptun NSP-E 70 Sensor Manual De Instrucciones Original

The non-return valve (Fig. 3/Item 7) prevents the
water in the hose fl owing back when the pump
is switched off . The use of the non-return valve
reduces the maximum delivery rate.
Water might escape from the ventilation opening
during operation.
When installing, never hang the equipment by
the discharge line or by the power cable. The
equipment must be hung up by the provided carry
handle or suspension eyelet, or it must rest on the
bottom of the shaft. To ensure that the equipment
works properly, the bottom of the shaft always
must be free of sludge and other accumulations
of dirt. If the water level is too low, the sludge
in the shaft can quickly dry out and hinder the
equipment from starting. It is necessary therefore
to check the equipment regularly (carry out trial
start-ups).
The pump shaft should be large enough.

5.2 Mains connection

Danger!
The equipment you have purchased comes with
an earthing-pin plug. The equipment is designed
for connection to a socket outlet with earthing
contact for 230 V ~ 50 Hz. Make sure that the
socket-outlet is suffi ciently fused (at least 6 A)
and in good working order. Insert the power plug
in the socket-outlet and the equipment is ready
for operation.
6. Operation
6.1 Starting up
You can put the equipment into operation after
you have thoroughly read the installation and ope-
rating instructions. Pay attention to the following
points:
•
Make sure that the equipment is set up secu-
rely.
•
Check that the discharge line is fitted correct-
ly.
•
Make sure that the electrical connection is
230 V ~ 50 Hz.
•
Check that the electrical socket-outlet is in
good working order.
•
Make sure that no moisture or water can ever
reach the power connection.
•
Make sure that the equipment does not run
dry.

To switch off the equipment, pull the power
plug out of the socket outlet.
6.2 Operating mode (Fig. 1/Item 2)
ON Manual mode
Autostart level 1: ON point 70 mm
Autostart level 2: ON point 135 mm
Autostart level 3: ON point 188 mm
6.3 Mode of operation of the integrated fl oat
switch
Application 1:
In ON mode the equipment will run continuously
and the water can be sucked up down to a level
of 40 mm. To prevent dry running, this operating
mode is allowed only under supervision. The
equipment must be switched off (pull out the pow-
er plug) as soon as no more water is emitted from
the discharge line.
Please note:
For the equipment to suck up water in ON mode
there must be a minimum depth of 50 mm of
water!
Application 2:
The pump can be used in autostart mode for ri-
sing water levels. When the preset autostart level
is reached, the pump starts automatically. Re-
gardless of the selected autostart level, the pump
will pump until 70 mm is left and will then continue
running on for a further 15 seconds before swit-
ching off automatically.
Please note:
The fact that it switches off automatically after
15 seconds prevents the pump from running dry
for any prolonged period of time. Since the pump
continues running, a low amount of noise may be
generated if there is no liquid, but this will not lead
to any damage to the pump. The water can be su-
cked up down to a level of 40 mm as a maximum.
Application 3:
The pump can be used in autostart mode where
the water level at the beginning is higher than the
preset autostart level. Regardless of the selected
autostart level, the pump will pump until 70 mm is
left and will then continue running on for a further
15 seconds before switching off automatically.
