WARNINGS 

1.

Use is allowed only if the electric system is in possession of safety precautions in accordance with the 
regulations in force. 

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. 

(Fig.1)

3.

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).
