► Tie the cable to the holes in the cover
of the electric pump;
► Lower the electric pump into the water
and fi x the cable over the well, well, etc.
The pump must be located at least 60 cm
from the bottom and 50 cm from the surface
of the water.
Do not allow the entry of foreign bodies, sharp
objects, etc. into the hole in the cover at the
bottom of the electric pump to avoid damage
to the rubber diaphragm.
Lower the electric pump, holding the cable
and pipeline, watch out for free suspension
of the power cord. When lowering the electric
pump, protect the cord from possible damage.
After lowering the electric pump into the well,
fix the cable and pipeline on the surface in
such a way that the weight of the pipeline and
the water in it is not transferred to the power
cord.
ATTENTION! The condensing box and the
socket must be placed under a shed or in-
doors, protected from possible exposure to
splashing water and atmospheric precipita-
tion.
To eliminate the possibility of clogging of the
pumping part, it is recommended to install a
check valve at the pump outlet.
Operating procedure
Before connecting the electric pump to the
network, make sure it is completely immersed.
Connect the electric pump to the mains with a
plug.
Attention! Operate the electric pump only in
a developed and cleaned well. If contaminat-
ed water appears, the electric pump should
be turned off and the position of the pump
relative to the bottom of the reservoir or well
should be checked again.
Remember that pumping water with a high
content of mechanical impurities leads to a re-
duction in the service life of the electric pump
and voids the right to warranty repair.
The performance of the electric pump de-
pends on the depth of the water, the length,
diameter and type of the pipeline used, etc.
To prevent pumping out of water from the
well, the well, match the productivity of the
latter with the volumetric fl ow of the pump by
closing the valve installed at the outlet of the
pipeline from the well, well. In this case, the
volumetric fl ow should not be less than 400 l
/ h. A further decrease in the volumetric fl ow
and complete shut-off of the valve can lead to
overheating and failure of the electric pump.
In order to avoid overheating and damage
to excess supply cable, during operation of
the electric pump, do not leave it in a tightly
wound coil, which impedes the access of air
for cooling.
In the event that the operating pump stops
due to the activation of the thermal relay,
turn on the electric pump after the relay has
cooled down and eliminate the causes of op-
eration by pressing the relay activation button
on the capacitor box (depending on the pump
model).
Lowering the voltage in the network when the
electric pump is running, leads to a decrease
in the head developed by the pump, produc-
tivity and to an increase in the current con-
sumption.
When the voltage in the network drops below
200V, it is recommended to use a voltage sta-
bilizer of the appropriate power, or bring the
voltage back to normal in another way.
Storage and maintenance
Be sure to flush the pump with clean water
after each use.
Storage
In case of prolonged inactivity of the pump, as
well as in winter, storage must be carried out
in a dry, heated room. First, it is necessary to
drain the remaining water from it and pipes,
rinse with clean water and dry.
The pump does not require preservation. It
should be stored at temperatures b 1
° C and + 35 ° C, away from heating devices
and avoiding direct sunlight.
Service
Have your power tool repaired by qualifi ed
personnel only and using original replace-
ment parts to ensure the safety of your
power tool. For a list of authorized service
centers, see the official P.I.T. link https://pit-

Description of product date
The date of manufacture of the product is
encrypted in the serial number printed on the
body of the instrument. The fi rst 2 digits indi-
cate the year of manufacture, the next 2 digits
are the month and the next 2 digits are the
day.
Recycling
When disposing of a damaged pump, take all
measures to avoid harm to the environment.
Do not attempt to dispose of the pump your-
self. It is highly recommended that you con-
tact the dedicated.
