2. Safety Instructions
DANGER! Electric shock!
Risk of injury due to electric shock.
v Always unplug your Garden Pump before fil-
ling, after operation, when trouble-shooting
and before carrying out any maintenance work.
CAUTION:
Keep cable plug dry!
RISK OF INJURY!
Hot water – risk of scalding!
If the pump is operated for prolonged periods of
time (> 5 min) with the delivery side closed, the
water in the pump may heat up so that there is
a risk of scalding yourself with hot water.
v The pump should not run against the closed
delivery side for more than 5 minutes.
If the water supply on the intake side of the
pump fails, the water in the pump can heat up
so that if water emerges, injuries could be
caused by the hot water.
v Disconnect the pump from the mains via
the main circuit breaker, let the water cool
and secure the suction-side water supply
before putting into operation again.
Location
Caution: Pursuant to DIN VDE 0100-702 and
0100-738 use of the pump nearby swimming pools
and garden ponds and other similar places is only
permissible if the pump is operated via a residual-
current device (FI switch) with a residual current
rating of ≤ 30 mA. The pump must not be operated
when there are persons in the swimming pool or
garden pond.The pump must be located on solid,
even ground, protected from flooding. Take care
that the pump cannot fall into water. Position the
pump at a safe distance (min. 2 m) from the liquid
to be pumped. As an additional safety device an
authorised safety switch can be used.
v Please ask your electrician for his advice.
When connecting the pump to the water supply
system, the country-specific sanitary regulations
must be observed to prevent water not of drink-
ing water quality being drawn back in.
v Please consult a specialist for sanitary
installations.
Extension cables
Data indicated on the type plate must match
technical data of the mains supply.
12
Pursuant to DIN VDE 0620, power cable as well
as extension cables must not have a smaller
diameter than rubber sheathed cables described
with letter symbols H05 RNF.
v Don't use the power cable for carrying the
pump or for plugging off.
In Austria
In Austria, the electrical connections must be
made according to ÖVE-EM 42, T2 (2000) /
1979 § 22 based on § 2022. Pursuant to this
regulation it's imperative to operate pumps for
swimming pools and garden ponds exclusively
via an isolating transformer.
v Please ask your electrician.
In Switzerland
In Switzerland mobile appliances which are
used outdoors, must be connected via a residual-
current device.
Visual check
v Before operating the pump, first make a visual
cheek, if there is any damage of the pump
(esp. regarding power cable and plug).
A damaged pump must not be used.
v In case of damage, please have the pump
checked by our GARDENA Service Centre or
by an authorised electrician.
Note
v Protect the pump from rain. Don't use the
pump in wet or moist area.
In order to avoid dry-running of the pump, take
care that the end of the suction hose is always
submerged into the liquid.
v Before each operation, fill the pump to over-
flowing with approx. 2 to 3 l of the liquid to be
pumped!
Sand and other abrasive substances in the liquid
cause in-creased wear and reduce the pump's
output.
v Use a pump preliminary filter for pumping
sandy liquids.
Pumping dirty water, e.g. stones, pine needles
etc., can cause damage to the pump.
v Do not pump dirty water.
The minimum flow rate is 90 l/h (= 1.5 l/min).
Watering accessories with lower rate must not
be operated.
3. Initial Operation
Setting up your Garden Pump:
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.
Connecting hose to
Don't use any hose connection system fittings on the
suction side:
suction side! A vacuum-resistant suction hose must be used,
e. g. GARDENA Suction Unit (suction hose Art. 1721,
suction hose fitting Art. 1724 and suction filter with backflow
Art. 1727.
In order to reduce the suction time, it is advisable to use a suction
hose with backflow preventer avoiding automatic draining of the
2
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

This relieves the pump of the weight of the suction hose.
Connection hose to
The 3500/4 pump has 2 connections

The pump connection not in use has to be closed by the cap
which can be unscrewed for connecting 2 hoses.

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
