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.
Storage and maintenance
Be sure to flush the pump with clean water
after each use.
Storage
ATTENTION! It is necessary to store the
equipment at an ambient temperature of 0 ° C
to + 40 ° C and a relative humidity of no more
than 80% in a place inaccessible to children.
Check regularly that all screws are secure. If
you fi nd a loose screw, tighten it immediately.
Otherwise, you put yourself at risk of injury.
Store and handle accessories with care.
If it is necessary to change the cord, to avoid
a hazard, contact an Authorized P.I.T. Power
Tool Service Center.
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.
Maintenance and cleaning
► Before any work on the machine itself
(e. g. maintenance, tool change, etc.) as
well as during transport and storage,
remove the battery from the power tool.
There is danger of injury when unintention-
ally actuating the On / Off switch.
► For safe and proper working, always
keep the machine and ventilation slots
clean.
When the battery is no longer operative,
please refer to an authorised after-sales ser-
vice agent for P.I.T. power tools.
