6. MANAGEMENT
Observe the current accident prevention
standards. Risk of crushing. The pump may
be heavy. Use suitable lifting methods and
always wear personal protection
equipment.
Before handling the product, check its weight to
identify suitable lifting equipment.
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 Handling KVC-KVCX / NKV 10-15-20
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.
6.3 Handling NKV 32-45-65-95
The pump motors supplied with eyebolt
should not be used to handle the whole
assembled electric pump (fig.1C).
For handling pumps with motor of up to 4kW, use the
belts wound around the motor as shown in fig. 1A.
For pumps with motor power greater or equal to
5.5kW, use the belts attached to the two flanges
located in the coupling area between the pump and the
motor as shown in fig.1B.
There is a risk that the pump may overturn
during handling; make sure that the pump
remains in a stable position during
handling.
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. 2
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
