3. INSTALLATION
Before you do installation:
WARNING! Electric shock!
Risk of injury due to electric shock.
v
Disconnect the product from the mains before you do
installation.
Installation location:
The pump must be installed in a location with an air humidity of
< 80 % 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 soil) may be sucked in through the
ventilation slots.

Set up the pump so that it is prevented from slipping and that an
appropriately large collecting vessel for draining the pump or the
system can be placed under the drain screw
1
.
The installation position must be firm and dry, and permit a secure
mounting for the pump.
Install the pump at a safe distance (min. 2 m) from the pumping
medium.
If possible, install the pump higher than the surface of the water to
be pumped. If this is not possible, install a vacuum-resistant shut-off
device between the pump and the suction hose to allow the inte-
grated filter to be cleaned.
If the system is permanently installed, appropriate shut-off devices
must be installed on the input and output sides. Important for
maintenance and cleaning work on the pump or for shutdown,
for example.
To connect the pump:
The GARDENA connectors on the suction and pressure sides
must be tightened only by hand. Check whether the seal ring
is present and undamaged before screwing the suction hose
onto the suction inlet. When using metal connections, dam
age could occur on the connection thread due to inappropri
ate assembly. Therefore, screw on the connection fittings
with the upmost care. Use only sealing tape for sealing metal
connections.
To Connect the suction hose:
Do not use modular water hose components on the suction side!
A vacuum-tight suction hose must be used e. g.:
• GARDENA Suction unit Art. no. 1411/1418
• GARDENA Bore Hole Suction Hose Art. no. 1729
• GARDENA Suction Hose sold by the metre and
Art. no. 1723/1724
If very fine dirt is present, we recommend the use of:
• a GARDENA pump pre filter Art. no. 1730/1731 in addition to the
integrated filter.
To reduce the pump repriming time, we recommend the
use of:
• a suction hose with backflow preventer, which prevents the suction
hose emptying automatically when the smart Pressure Pump is
switched off.
