5. WARNINGS

The pumps must never be carried, lifted or allowed to operate suspended from the power cable; use the
handle provided.
 The pump must never be allowed to run when dry.
It is recommended to open/close the venting/drainage caps (2 and 6) without applying excessive force.

The pump must be installed in a place protected from unfavourable weather conditions, and with an environment
temperature not higher than 40°C.
The pump is provided with vibration-damping rubber feet, but in the case of fixed installations it is possible to remove them
and provide anchorage to the base (7).
Do not allow the pipes to transmit excessive forces to the pump inlets (3) and (4), to avoid creating deformations or
breakages.
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 pipes must never have an internal diameter smaller than that of the pump inlets; on intake, the pump is provided with
a filter (1) and a non-return valve (NRV) (5).
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.2
If the suction pipe is made of rubber or flexible material, always check that it is of the reinforced vacuum-resistant type to
avoid shrinkage due to suction.
In case of a fixed installation, it is recommended to fit a closing valve on both the suction side and the delivery side. This
allows closure of the line upstream and/or downstream from the pump, useful for service and cleaning operations or for
periods in which the pump is not in use.
The pump has a rotating inlet to facilitate installation (3) and (4)
In the case of flexible pipes, if necessary, use a bend fig. 1 and the gardening kit composed of a PE pipe and a kit of
couplings with lance. These are not supplied, but can be bought separately. In the case of very small dirt, as well as the
integrated filter (1), it is recommended to use a pump inlet filter fitted on the suction pipe.
 Do not subject the motor to excessive starts/hour; it is strongly recommended not to exceed 20 starts/hour.
The diameter of the suction pipe must be greater than or the same as the diameter of the pump inlet,
see Table 3.

7. ELECTRICAL CONNECTION

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.
table 3.
The length of the power cable on the pump limits the installation distance, if an extension is required,
make sure that it is of the same type (e.g. H05 RN-F or H07 RN-F depending on the installation) see tab.

8. START-UP

Do not start the pump without having completely filled it with liquid, about 4 litres, until it comes out of the air
vent cap (2).
If the water supply is finished, take the plug out of the socket immediately and switch off the pump. Avoid dry running.
