Safety
Use is allowed only if the electric system is in possession of safety precautions in accordance with the
regulations in force in the country where the product is installed (for Italy, CEI 64/2).
6.3
Checking motor shaft rotation
Before installing the pump you must check that the rotating parts turn freely. For this purpose remove the fan
cover from its seat in the motor end cover. Insert a screwdriver in the notch on the motor shaft from the
ventilation side. If there is a blockage, turn the screwdriver, tapping it gently with a hammer. FIG. A
6.4
Responsibility
The Manufacturer does not vouch for correct operation of the pumps if they are
tampered with or modified, run outside the recommended work range or in contrast with
the other instructions given in this manual.
The Manufacturer declines all responsibility for possible errors in this instructions
manual, if due to misprints or errors in copying. The company reserves the right to make
any modifications to products that it may consider necessary or useful, without affecting
the essential characteristics.
7.
INSTALLATION
The pumps may contain small quantities of residual water from testing.
We advise flushing them briefly with clean water before their final installation.
7.1
The electropump must be fitted in a well ventilated place, protected from unfavourable weather
conditions and with an environment temperature not exceeding 40°C. Fig.B
7.2
A firm anchoring of the pump to the bearing surface favours the absorption of any vibrations caused
by pump operation. Fig. C
7.3
Ensure that the metal pipes do not exert undue strain on the apertures, thus preventing deformations
or breakages. Fig. C
7.4
It is always good practice to place the pump as close as possible to the liquid to be pumped. The
pump must be installed only in horizontal position. The internal diameters of the pipes must never be
smaller than that of the mouth of the electropump. It is advisable to fit a foot valve on suction. Fig. D
For suction depths of over four metres or with long horizontal stretches it is advisable to use an intake
hose with a diameter larger than that of the intake aperture of the pump. To prevent the formation of air
pockets, the intake hose must slope slightly upwards towards the pump. Fig. D
7.5
If the intake pipe is made of rubber or flexible material, always check that it is of the reinforced type
to avoid throttling due to suction.
7.6
The lifting and carrying handle must always be present and well fixed to the support on all
pumps produced in the portable version.
7.7
Pumps that are to be used in fountains for outdoor use, in garden ponds and similar places,
must be fed by means of a circuit equipped with a differential current device, the rated
operating differential current of which is not higher than 30 mA.
8.
ELECTRICAL CONNECTION
Caution! always follow the safety regulations.
Scrupulously follow the wiring diagrams inside the terminal board box.
8.1
Electric installation must be carried out by skilled and authorized electrician who accepts all
the responsibility for the job.
8.2
Ensure that the mains voltage is the same as the value shown on the motor plate and that there is the
possibility of MAKING A GOOD EARTH CONNECTION (Fig. E), in particular the earth
terminal must be connected to the yellow/green lead of the power cable.
The earth lead used must
be longer than the phase leads so that it does not disconnect first when subject to traction.
8.3
In fixed installations, International Safety Standards require the use of isolating switches with a
fuse-carrier base.
8.4
Single-phase motors are provided with built-in thermal overload protection and may be connected
directly to the mains. Three-phase motors must be protected with an automatic switch (e.g. overload
protection) set at the values on the electropump data plate, or with fuses of the size indicated in
chapter 4.
