WARNINGS
1.
Use is allowed only if the electric system is in possession of safety precautions in accordance with the
regulations in force.
The appliance is not intendend for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsable for their safety. Children should be
supervised to ensure that they do not play with the appliance.
2.
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.
The pumps must never be carried, lifted or made to operate hanging
from their power cable.
3.
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.
4.
Qualified personnel must also be employed for all electrical repairs which, if badly carried out, could
cause damage and accidents.
5.
The pump must
never
be allowed to run dry.
6.
The Manufacturer does not vouch for correct operation of the pump if it is tampered with or modified.
INSTALLATION
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-Fig.3)
.
2.
Before putting the pump in position, ensure that the strainer is not totally or partially blocked by
mud, sediment or similar substances.
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.
4.
Totally immerse the pump in the water.
INSTALLATION
FEKA VS-VX
1.
On the version provided with a float
switch, ensure that the float can move
freely (SEE THE PARAGRAPH ON
ADJUSTING THE FLOAT SWITCH).
Ensure that the
minimum 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.
2.
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.
