The installation position must be firm and dry, and permit a secure
mounting for the Electronic Pressure Pump.
v Install the Electronic Pressure Pump at a safe distance
(min. 2 m) from the pumping medium.
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 earth) may be sucked in through the
ventilation slots.
Set up the Electronic Pressure 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 .

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 system is being installed permanently, please fit suitable
valves on both the intake and delivery sides.
For example, important for maintenance and cleaning work on
the pump or for shutdown.
The GARDENA connection pieces on the intake and delivery
sides may only be tightened by hand. When using metal
connections, damage could occur on the connection thread
due to inappropriate assembly. Therefore, screw on the
connection fittings with the upmost care.
Do not use any water hose snap connection system components
on the intake side! A vacuum-tight suction hose must be used
e. g.:
• GARDENA Suction Hose Art. no. 1411 / 1418
• GARDENA Bore Hole Suction Hose Art. no. 1729.
To reduce the pump repriming time, we recommend:
• Using a suction hose with backflow preventer, which prevents
the suction hose emptying automatically when the Electronic
Pressure Pump is switched off.
• with larger suction heads, use a suction hose with a smaller
diameter (3/4").
1. Connect the vacuum resistant suction hose, sold by the metre
, using the suction hose fitting
2
with the connector on the suction side
2. For suction heights exceeding 4 m also secure the suction hose
(e. g. by fastening it to a wooden post).
This relieves the pump of the weight of the suction hose.
If very fine dirt is present, we recommend the use of
a GARDENA pump preliminary filter Art. no. 1730 / 1731
in addition to the integrated filter.
(e. g. Art. no. 1723/1724)
