For safety reasons we recommend that you always operate
the Dual Pump via a residual-current device (DIN VDE 0100-702
and 0100-738).
vPlease contact your electrician.
In Austria, according to ÖVE B/EN 60 555 part 1 to 3, pumps
which are used in swimming pools and garden ponds, and
equipped with firm power cable should be fed via an ÖVE
approved isolating transformer – rated voltage must not exceed
230 V.
In Switzerland mobile appliances which are used outdoors,
must be connected via a residual-current device.
According to DIN VDE (German Electrical Engineers’ Associa-
tion) 0620, mains power cables must not have a smaller cross-
section than the rubber-sheathed cables of the designation
H07 RNF. The cable length must be at least 10 m.
Data indicated on the type plate must match technical data of
the mains supply.
vTake care that the electrical connections are made within
dry area, protected from flooding.
Protect plug and power cable from heat, oil and sharp edges.
vDon’t use the power cable for plugging off.
The power cable must not be used for mounting or relocating
the pump. For submerging or lifting/ securing the pump, fix a
rope (available from GARDENA Service) to the pump’s carrying
handle.
Extension cables must meet the requirements of DIN VDE
0620.
vBefore operating the pump, first make a visual check, if there
is any damage of the pump (esp. regarding power cable and
plug).
vObserve the minimum water level and the max. delivery
height (see 9. Technical Data).
A damaged pump must not be used.
vIn case of damage, please have the pump checked by our
GARDENA Service Centre.
vClear the outlet line before use.
When setting up the pump for use out of water
In order to avoid dry-running of the pump, take care that the
end of the suction hose is always submerged into the liquid.
vBefore each operation, fill the pump to overflowing with
approx. 2 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.
vUse a Pump Preliminary Filter if the water contains sand
(Art. No. 1730 / 1731).
The pump should not run against the closed delivery side
for more than 5 minutes.
vIf liquid fails to flow, switch off the pump immediately.

Dry-Running
Liquid fails to flow
The minimum flow rate is 80 l/h (= 1.3 l/min).
Watering accessories with lower rate must not be operated.
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.
vThe pump should not run against the closed delivery side for
more than 5 minutes.
vIf liquid fails to flow, switch off the pump immediately.

3. Initial Operation
1. When setting up the pump for use underwater, screw the
filter 1onto the connection 2at the inlet side of the pump.
– or –
When setting up the pump for use out of water, connect a
vacuum-resistant suction hose 3with filter to the connec-
tion 2at the inlet side of the pump and screw on so that the
connection is air-tight.
2. When setting up the pump for use out of water with suction
heights over 4 m, the suction hose should also be secured (fas-
tened to a wooden peg for example).
The pump is relieved of the weight of the suction hose.
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.
Both pump connectors 4are equipped with a 33.3 mm (G 1”)
thread to which 13 mm (1/2”), 19 mm (3/4”) and 16 mm (5/8”)
hoses can be connected by using GARDENA hose connection
system fittings.
Best results regarding the delivery capacity of the pump are
achieved when connecting 19 mm (3/4”) hoses in conjunction
with e.g.
•GARDENA Pump Connection Set, art. no. 1752,
or when using 25 mm (1”) hoses with fittings available from your
sanitary dealer.
vConnect the pressure hose 5to the connector 4on the
delivery side.
Only when setting up the pump for use out of water:
VBefore each operation, fill the pump to overflowing
Awith approx. 2 l of the liquid to be pumped !
1. Unscrew the screw fitting 6of the filler cap 7by hand.
2. Fill the pump via the filler cap 7to overflowing with approx.
2 l of the liquid to be pumped.
3. Tighten the screw fitting 6of the filler cap 7by hand (do not
use pliers).
