Self-priming Pump
4
The principle of the station is that the water
supply network is always under pressure. If
you turn on a tap or other device, the pres-
sure in the system will begin to drop. When
the pressure drops below 0.15 MPa (1.5
atm.), The pressure switch will automatically
turn on the pump, and it compensates for the
water fl ow. When you close the tap, the pump
will run for a while.
Water will fi ll the accumulator, and when the
pressure in the system rises to the initial state
of 0.3 MPa (3 atm.), The pump will automati-
cally turn off using a pressure switch.
Station installation and commis-
sioning
Before connecting, be sure to check the com-
pliance of the electrical and pressure data of
the product with the parameters of your elec-
trical and water supply network.
It is desirable that the installation and com-
missioning of the station be carried out by a
specialized installation organization. The sta-
tion should be secured to a rigid base.
To reduce noise and vibration during the op-
eration of the station, its fastening to the base
should be carried out through rubber washers
and gaskets.
ATTENTION! A prerequisite for the operation
of the station is the presence of a 1 ”check
valve at the inlet of the suction line (not in-
cluded in the set).
Connect a suction pipe with a 1 ”check valve
at the end to the station inlet (7). Connect a
standpipe to the station outlet (8). The suction
line is made from an incompressible hose or
pipe.
ATTENTION! The diameter of the hose or
pipe must exactly match the diameter of the
pump inlet - 1 inch.
Avoid connections that narrow or widen the
fl ow area of the hose or pipe. The installation
of fi lter elements on the suction line is strictly
prohibited.
ATTENTION! All connections of the suction
and pressure pipelines must be tight.
Installing a suction line with a length of more
than 10 meters horizontally is not advisable,
as this will lead to a decrease in the suc-
tion lift. When installing the suction line, it is
necessary to ensure a continuous angle of
inclination from the station to the water intake
source of at least one degree to the horizon,
reverse angles on the suction line are not al-
lowed.
Electrical connection
ATTENTION! The electrical connection
should only be carried out after all hydrau-
lic connections have been completed.
The electrical connection must be carried
out by a qualified technician. The station
should be installed in such a way that easy
access to the electrical outlet is provided.
The socket should only be used for powering
the station, be grounded and connected to
a high sensitivity (30 mA) differential circuit
breaker. The installation location of the sock-
et must be protected from splashing water.
ATTENTION! It is forbidden to operate the
station with a damaged electric cable. In case
of damage to the electrical cable, you must
contact the service center to replace it.
Commissioning
At the initial start-up, it is necessary to pre-
fill the pump and the suction line with water
through the fi ller hole (9). To do this, unscrew
the plug and fi ll with water until water begins
to flow out of the filler hole without air bub-
bles, then screw the fi ller plug. Before starting
the station, it is necessary to check the air
pressure in the accumulator using a car pres-
sure gauge by connecting it to the pneumatic
valve (6), it should be 0.15 MPa (1.5 atm). If
necessary, pump air into the accumulator us-
ing a car pump, otherwise the diaphragm may
rupture.
After opening all water intake taps to remove
air from the pressure line, connect the station
to the power grid. The station pump will start
to deliver water.
Service
Have your power tool repaired only by quali-
fi ed personnel and only with original replace-
ment parts. This ensures the safety of the
power tool.

Storage and transportation
Storage:
drain the suction and discharge pipes
unscrew the drain plug and let the water drain
out of the pump
screw the drain plug again and store the
pump and accessories in a frost-protected
place, at a temperature of 0 to + 35 ° C and a
relative humidity of no more than 80%.
Products can be transported by any type of
closed transport in the manufacturer’s pack-
aging or without it, while preserving the prod-
uct from mechanical damage, atmospheric
