6. MANAGEMENT
6.1 Storage
All the pumps must be stored indoors, in a dry,
vibration-free and dust-free environment, possibly with
constant air humidity.
They are supplied in their original packaging and must
remain there until the time of installation. If this is not
possible, the intake and delivery aperture must be
accurately closed.
6.2 Transport
Avoid subjecting the products to needless jolts or
collisions. To lift and transport the unit, use lifting
equipment and the pallet supplied standard
(If applicable). Use suitable hemp or synthetic ropes
only if the part can be easily slung, connecting them if
possible to the eyebolts provided.
In the case of coupled pumps, the eyebolts provided
for lifting one part must not be used to lift the pump-
motor assembly.
7. WARNINGS
7.1 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 ).
7.2 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.
Fig. 1
Do not force the fan with pliers or other
tools to try to free the pump as this could
cause deformation or breakage of the
pump
.
7.3 New systems
Before running new systems the valves, pipes, tanks
and couplings must be cleaned accurately.
To avoid welding waste or other impurities getting into
the pump, the use of TRUNCATED CONICAL filters
made of corrosion resistant materials (DIN 4181) is
recommended.

8. PROTECTIONS
8.1 Moving parts
Before starting the pump all the moving parts have to be
properly protected with dedicated components ( fan,
cover, etc. ).
During pump operation, keep well away
from the moving parts ( shaft, fan, etc. ).
If getting closed to the running pump is necessary, be
properly dressed as from laws rules, in order to avoid
injuries.
