− handling clear water as well as dirty or sewage water with solids in
suspension up to the diameter indicated in chap. 12;
− pumping water out of garages, cellars, basements, tanks, reservoirs,
fountains, rainwater drains;
− flood irrigation of vegetable patches and gardens and oxygenating
water. The series can also be used to drain rainwater drains, cess-
pits and septic tanks, and trenches etc..
WARNING!
ONLY USE MOTOR-DRIVEN PUMPS FOR CONTINUOUS
DUTY IF THEY ARE FULLY SUBMERSED.
DO NOT USE MOTOR-DRIVEN PUMPS WITH THE MOTOR
OUT OF WATER FOR MORE THAN 15 MINUTES.
Use the motor-driven pumps based on their technical specifications.
USE FOR WHICH PUMPS ARE NOT DESIGNED
The pumps cannot be used to handle:
− water containing acids or bases, and corrosive liquids in general;
− water with a temperature over the temperature limit given in chap. 12.
− seawater;
− flammable liquids and hazardous liquids in general;
− cannot be used in swimming pools (according to EN 60335-2-41);
− pumps with a cable less than 10m long cannot be used outdoors.
The motor-driven pumps must never be made to work without liquid.
6. TECHNICAL-PRODUCTION CHARACTERISTICS
The motor-driven pump you have purchased has been designed and
manufactured in compliance with the following directives:
• MECHANICAL HAZARDS (Annex I Machinery Directive):
- UNI EN ISO 12100
• ELECTRICAL HAZARDS (Annex I Machinery Directive):
- UNI EN ISO 12100
- CEI EN 60204-1
• VARIOUS RISKS (Enclosure I Machines Directive):
- 2006/42/EC – Enclosure I
The electrical components and relative circuits installed on the mo-
tor-driven pumps are in accordance with the CEI EN 60204-1 Directive.
7. INSTALLATION AND DISMANTLING, TRANSPORT
AND STORAGE
WARNING!
INSTALLATION MUST BE CARRIED OUT BY A
QUALIFIED ENGINEER.
7.1. GENERAL INSTALLATION PRECAUTIONS
a) Use metal or rigid plastic 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 non-return valve and a gate are installed on the
delivery pipe at the motor-driven pump outlet;
f) fix the piping to the reservoir or to any fixed parts so that it is not support-
ed by the pump;
g) do not use a lot of bends (goosenecks) and valves;
7.2. INSTALLATION
WARNING!
USE A ROPE FASTENED AROUND THE HANDLE TO LIFT
OR LOWER THE MOTOR-DRIVEN PUMP: NEVER PULL THE
POWER CABLE AND/OR FLOAT CABLE AND SWITCH (FIG. 15).
a) It is best to use rigid pipes (metal pipes on series) for permanent
installations and flexible pipes for temporary installations, with sizes
as given in chap. 12, observing the distances illustrated.
b) use pipes of suitable diameters fitted with threaded sleeves that must
be screwed onto the pump suction and delivery unions or its threaded
counterflanges;
INSTALLING PUMP WITH FLANGE
a) Using the relevant screws, fasten the mount on the surfaces due to
support the pump;
b) screw the delivery pipe onto the mount;
c) the mount features a rod with a guide along which you slide the hook
required to lower the pump;
d) lower the motor-driven pump, holding it by the rope fastened around
the handle, until the flange slots into place on the mount;
e) the motor-driven pump couples with the mount under its own weight.
7.3. DISMANTLING
The following must be done when moving or dismantling the motor 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 motor-driven pump to its
supporting surface;
d) if present, hold the power cable;
e) lift the motor-driven pump using equipment suitable to the pump weight
and dimensions (refer to the plate).
7.4. TRANSPORTATION
The motor-driven pump is packed in a carton or can be fixed to a wooden
pallet, if pump weight and dimensions allow it. Transportation should not, in
any case, present any particular problems.
Verify the total weight stamped on the box.
7.5. 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 me-
chanical damage.
c) Do not place heavy objects on the packaging.
d) The product must be stored at an ambient temperature between +5°C
and +40°C (41°F – 104°F) with a relative humidity of 60%.
8. ELECTRICAL CONNECTION
− ELECTRICAL CONNECTION MUST BE CARRIED OUT BY A
QUALIFIED ENGINEER.
− IT IS ADVISABLE TO INSTALL A HIGH INTENSITY DIFFER-
ENTIAL SWITCH (0.03 A) ON BOTH THE THREEPHASE AND
SINGLE PHASE VERSIONS.
WARNING!
Motor-driven pumps not equipped with a plug must be
powered by connecting them permanently to the elec-
trical cabinet equipped with a switch, fuses and thermal
cut-out calibrated to the pump's absorbed current.
The mains must be reliably earthed, according
to the electrical regulations in force in the user's
country: this is the installer's responsibility.
If the motor-driven pump is supplied without a
power cable, use a cable that complies with the
regulations in force and the necessary section ac-
cording to length, power and mains voltage.
If present, the plug of the single phase version must
be connected to the mains far from sprays, water
jets or rain and it must be accessible.
The three phase version does not have an internal
motor protector, therefore overload protection
must be provided by the user.
