1. INSTALLATION
Checking motor shaft rotation
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.
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.

2. ELECTRICAL CONNECTION
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
1.2
A firm anchoring of the pump to the bearing surface favours the absorption of any
vibrations caused by pump operation.

1.3
Ensure that the metal pipes do not exert undue strain on the apertures, thus preventing
deformations or breakages.
Fig. C
1.4
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.

1.5
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.
1.6
The lifting and carrying handle must always be present and well fixed to the support on all
pumps produced in the portable version.
1.7
Electric installation must be carried out by skilled and authorized electrician who accepts
all the responsibility for the job.
2.1
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.
1.8
Caution! always follow the safety regulations.
Scrupulously follow the wiring diagrams inside the terminal board box.
