a horizontal position
the motor is not allowed (see Figure 3.3c)
off valves on the pressure and suction side of the pump
and unscrew the screws (Figure 3.3). Turn the electric
motor part as shown in Figures 3.3a or 3.3b.
7.2 DISMANTLING
In order to handle and dismantle the electropump you should:
a) Take off the power supply.
b) Lift the electropump with suitable means according to
its weight and dimensions

7.4. TRANSPORT
The electropump is packed in a carton or, depending on
its weight and dimensions, it is fixed on a wooden pallet;
however, transport does not present many difficulties.
In any case, check the total weight imprinted on the box.

8.1. PROTECTIVE DEVICES
ACCORDING TO THE LAW BY A QUALIFIED TECHNICIAN.
TO THE EARTH OF THE PLANT ACCORDING TO
THE ELECTRICAL STANDARDS IN FORCE IN YOUR
COUNTRY: THE INSTALLER SHALL BE THE SOLE
RESPONSIBLE FOR IT.
WE RECOMMEND INSTALLING A HIGH SENSITIVE
DIFFERENTIAL SWITCH (0.03 A).
After installing the unit check again the feeding cable
following the CABLE CONNECTION instructions and
connect it to the control panel (1) that must be fitted,
according to the actual rules, with:

is being ventilated during the start-up. The air in the
pump generates noise. After a short working period
noise should disappear.

During its running, it is normal for the pump to
heat up, or to be heated by the pumped fluid - to
prevent from risk of burns, it should therefore
not be touched!

electric motor housing should not be insulated, since
the thermal insulation might hinder cooling and drainage
of condensate from the pump's motor housing.
