1. PUMPED FLUIDS
These pumps cannot be used in swimming pools, ponds or tanks in which people or present, or for pumping hydrocarbons
(petrol, diesel fuel, fuel oils, solvents, etc.) in accordance with the accident-prevention regulations in force.
N.B.: The liquid inside the pump, to lubricate the seal device, is not toxic but it may alter the characteristics of the water (if it is pure water) if there
is a leak in the seal device.

3. WARNINGS
The pump is provided with a carrying handle which may also be used to lower it into wells or deep holes with a rope or cable.
–
– If the power cable is damaged in any way it must be replaced and not repaired (use cable type H07RN-F diam. 9 – 9.5 mm. with minimum
length 10 metres for the portable version, with a UNEL 47166-68 plug for the SINGLE-PHASE version and with an EEC plug for the THREE-
PHASE version).This must be done by skilled personnel, in possession of the qualifications required by the regulations in force .
– The pump must never be allowed to run dry.
4. INSTALLAZIONE
4.1 If the bottom of the well or borehole in which the pump is to operate is particularly dirty, it is advisable to provide a support for the pump to
sit on so as to avoid clogging of the intake grid (Fig.1).
4.2 Before putting the pump in position, ensure that the strainer is not totally or partially blocked by mud, sediment or similar substances.
4.3 It is advisable to use pipes with an internal diameter at least equal to that of the delivery mouth, to avoid falls in pump performance and
the possibility of clogging. In cases where the delivery pipe has long horizontal stretches, it is advisable for this pipe to have a larger
diameter than that of the delivery mouth.
Totally immerse the pump in the water.

− from 0°C to +50°C for other uses
1. Connect the delivery pipe or hose directly to the pump mouth. If the pump is used in fixed
installations it is advisable to connect it to the pipe with a coupling so as to facilitate disassembly
and reinstallation. If a hose is used, fit a threaded hosetail on the pump mouth. Wrap the thread
with suitable material to ensure an effective seal (teflon tape or similar)
2. On the version provided with a float switch, ensure that the float can move freely (SEE THE
PARAGRAPH ON ADJUSTING THE FLOAT SWITCH).
dimensions of the borehole are as in Fig.1. The dimensions of the borehole must also be
calculated with relation to the quantity of water arriving and to the pump flow rate so as not to
subject the motor to excessive starting operations.
3. When the pump is to be in a fixed installation, with a float, a check valve must always be fitted
in the delivery pipe. This is also advisable on pumps with manual operation.
