The minimum flow rate is 90 l/h (= 1.5 l/min.).
Watering accessories with lower rate must not
be operated.
The site must be firm and solid in order to ensure safe and sturdy
operating conditions for the pump.
v Position the pump at a safe distance (min. 2 m) from the liquid
to be pumped.
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 dirtcontamination (e.g. sand or earth) may be sucked in
through theventilation slots.
Don't use any hose connection system fittings on the
suction side! A vacuum-resistant suction hose must be used,
e. g. GARDENA Suction Unit, art. no. 1411.
In order to reduce the suction time, it is advisable to use a suction
hose with backflow preventer avoiding automatic draining of the
suction hose when the pump is stopped.
1. Screw a vacuum-resistant suction hose
connector on the suction side of the pump
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.
The 3500/4 pump has 2 connections
The pump connection not in use has to be closed by the cap

The pump connections
thread which can be used to connect 13 mm (1/2"), 16 mm (5/8")
or 19 mm (3/4") hoses via the GARDENA hose connection system.
Optimised use of the pump capacity is achieved by connecting
19 mm (3/4") hoses with e.g. GARDENA Pump Connection Set
Art. 1752, or by connecting 25 mm (1") hoses with GARDENA
Quick Thread Coupling with female thread Art. 7109 / Quick
