a) Unscrew the cap located on the top of the pump casing;
b) With the aid of a funnel, fill the pump with water to overflowing
c) Screw the cap back on until it is locked tight to prevent air getting in
9.2 GENERAL INSTALLATION PRECAUTIONS
a) Use metal pipes in order to avoid their yielding because of the
depression created at suction;
b) support and align pipes so that they do not put any stress on
the pump;
c) avoid throttlings caused by bending suction and delivery hoses;
d) seal any piping connections: air infiltration in the suction pipe
negatively affects pump operation;
e) we recommend that a gate valve are installed on the delivery pipe
at the electropump outlet;
f) fix the piping to the reservoir or to any fixed parts so that it is not
supported by the pump;
g) do not use a lot of bends (goosenecks) and valves;
h) If the pump is installed over head, the suction pipe should be
fitted with a foot valve and filter in order to prevent foreign bodies
from entering and its end should be immersed at a depth that
is at least twice the diameter of the pipe; its distance from the
bottom of the reservoir should also be one and a half times its
diameter. For suctions longer than 4 metres use an oversized
pipe (1/4” wider at suction for improved efficiency);
i) Force exclusion of dry run protection by holding down the
restart button for up to 5 minutes (only in above-deck installation
condition);
j) In case of failure to start after 5 minutes, release the restart
button, disconnect power, wait 10 minutes, and repeat the
operations described in chapter 9.1.
9.3 INSTALLATION
a) Position the pump on a flat surface that is as close as possible to
the water source. Leave enough space around the pump to allow
safe use and maintenance. A free space of at least 100 mm must
be kept in front of the cooling fan of surface pumps in all cases;
b) use pipes of suitable diameters fitted with threaded sleeves that
must be screwed onto the pump suction and delivery unions.
c) HYDROSTATION cannot be used outdoor except as stated
9.4 DISMANTLING
The following must be done when moving or dismantling the pump:
a) disconnect the electric supply;
b) remove the delivery and suction pipes (where present) if too long
or bulky;
c) if present, unscrew the screws that secure the pump to its
supporting surface;
d) if present, hold the power cable;
e) lift the pump using suitable equipment
9.5 TRANSPORTATION
The electropump is packed in a carton box, in any case, the
transport does not present any particular problems.
9.6 STORAGE
a) The product must be stored in a covered and dry place, far away
from heat sources and protected against dirt and vibrations.
b) Protect the product against damp conditions, heat sources and
mechanical damage.
c) Do not place heavy objects on the packaging.
d) The product must be stored at an ambient temperature between
+5°C and +50°C (41°F – 122°F) with a relative humidity of 60%
10. ELECTRICAL CONNECTION
IT IS ADVISABLE TO INSTALL A HIGH INTENSITY
DIFFERENTIAL SWITCH (0.03 A)
ATTENTION!
The plug must be connected to the mains in an
indoor ambient far from sprays, water jets or rain
and it must be accessible.
The mains must be reliably earthed, according
to the electrical regulations in force in the user’s
country: this is the installer’s responsibility.
11. AUXILIARY CONNECTION
Bluetooth Optional Bluetooth plug-in position
+V +12Vcc main contact
Press SW / 0V External pressure switch input
Float SW / 0V Float switch input
Ext On/Off / 0V ON/Off remote input
COM RS485 Communication input between devices
12. USE AND STARTING
NEVER ALLOW THE PUMP TO OPERATE WITHOUT WATER.
DOING SO CAN SERIOUSLY DAMAGE THE INTERNAL
COMPONENTS.
12.1 GENERAL WARNINGS
a) Our surface pumps are designed to operate at a temperature no
higher than 50°C and a sea level no higher than 1000 metres;
b) The pump cannot be used in swimming pools or similar plants;
c) Prolonged pump operation with the delivery pipe closed can
cause damage for overheating;
d) Avoid switching the pump on and off more than 50,000 times
a year. If the pump operates on and off for more than 50,000
times per year, the pump life may be shortened and there is a risk
of premature failure.Regarding the maximum number per hour,
please refer also Chapter 8;
e) During power cuts, it is advisable to disconnect the power to the
pump;
12.2 STARTING
a) Connect the pump to the main power;
