3. Initial Operation
Installing the
Pressure Tank Unit:
The installation position must be firm and dry, and permit a secure
mounting for the pressure tank unit.
v
Install the Pressure Tank Unit at a safe distance from the
pumping medium.
The pump must be installed in a location with low air humidity and
sufficient ventilation in the area of the ventilation slots. It must be
at a distance of at least 5 cm from the walls. No dirt contamination
(e. g. sand or earth) may be sucked in through the ventilation slots.
Fixed installation of the
Pressure Tank Unit:

The Pressure Tank Unit can be screwed with all 4 feet

onto
a solid surface

.
Alternatively, spring mounted feet (Art. 1753-00.901.00) for low
vibration and quiet running are available as accessories via the
GARDENA Service.
Install the pressure tank unit so that there is room to place
a suitably sized drainage tray under the drain screw
3
to allow
the unit or system to be drained.
If possible, install the unit higher than the surface of the water to
be pumped. If this is not possible, install a vacuum-resistant valve
between the unit and the suction hose, for example for cleaning
the integrated filter.
If the pressure tank unit is being permanently installed indoors
for domestic water supply, the Pressure Tank Unit should not be
connected to the domestic water pipework with rigid pipes but
with flexible hoses, to reduce noise and to avoid damage to the
pressure switch due to vibration.
If the system is being installed permanently, please fit suitable
valves on both the intake and delivery sides. This is important
e. g. for maintenance and cleaning work or if the system is being
shut down.
The connection pieces on the intake and delivery sides may
only be tightened by hand.
Connect the hose to
the suction side:

Art. 1724

A vacuum-tight suction hose must be used e. g.:
– GARDENA Suction Unit Art. no. 1411 / 1418 / 1412 or
– GARDENA Bore Hole Suction Hose Art. no. 1729.
Do not use any water hose snap connection system components
on the intake side!
v
Connect the suction hose

with the intake side
connection

of the pump.
Connect the suction hoses

without a threaded connector via
a connection piece (e.g. Art. no. 1723/1724)
4
with the intake side
connection and screw in place so that they are airtight.
To reduce the pump repriming time, we recommend using
a suction hose with backflow preventer, which prevents the
suction hose emptying automatically when the Pressure Tank Unit
is switched off.
