4.4 Stopping the pump
The pump has a built-in electronic protection function
which allows it to stop in the event of:
−
dry running,
−
overheating,
−
motor overload,
−
blockage of the pump / motor.
After stopping in this way, the pump restarts
automatically, making 3 attempts of 3 minutes each,
with pauses of 10 seconds.
The starting attempts will be repeated, in the event of
a negative result:
−
after 1 hour : 1 attempt of 3 minutes,
−
after 4 hours : 1 attempt of 3 minutes,
−
every 15 hours : 1 attempt of 3 minutes.
To perform manual resetting of the pump you must
supply power to it again, disconnecting the voltage for
a few seconds.
5. INSTALLATION AND CONNECTION
5.1 Pump installation
−
The electropump must be installed in a well
ventilated place, protected from inclement weather
and with an environment temperature no higher
than 40°C.
−
A solid anchoring of the pump to its support base
helps absorb any vibrations created by pump
operation.
−
Always fit the pump on a base with the intake
opening horizontal and the delivery opening
vertical.
−
The pump must be installed exclusively in
horizontal position (Fig.3):
−
To avoid transmitting vibrations to the system, after
delivery it is recommended to use the flexible pipe
that is supplied inside the packing. (Fig.4).
−
Do not allow the metal pipes to weigh down on the
pump openings, transmitting excessive strain, so as
not to create deformations or breakages. Anchor the
pipes separately if possible.
−
The suction pipe must be as short as possible. For
suction depths of more than 4 metres or with long
horizontal stretches, it is recommended to use a
suction pipe with a diameter larger than that of the
suction opening of the electropump.
−
To avoid the formation of air pockets in the suction
pipe, ensure a slight positive tilt of the same towards
the electropump.
−
If it is not possible to use the flexible pipe to make
the connection, use only Teflon tape. (Fig.5).
−
For any maintenance jobs it is recommended:
•
to fit an interception valve along the pipe, close
to the pump (Fig.6),
•
to use a straight length of pipe, after delivery, for
lifting the cover of the Active system, in the event
of inspection (Fig.6).
