For safety reasons we recommend that you always operate
the Dual Pump via a residual-current device (DIN VDE 0100-702
and 0100-738).
v Please 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.
v Take care that the electrical connections are made within
dry area, protected from flooding.
Protect plug and power cable from heat, oil and sharp edges.
v Don’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.
v Before operating the pump, first make a visual check, if there
is any damage of the pump (esp. regarding power cable and
plug).
v Observe the minimum water level and the max. delivery
height (see 9.Technical Data).
A damaged pump must not be used.
v In case of damage, please have the pump checked by our
GARDENA Service Centre.
v Clear 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.
v Before 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.
v Use 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.
v If 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.
v The pump should not run against the closed delivery side for
more than 5 minutes.
v If liquid fails to flow, switch off the pump immediately.

3. Initial Operation
1. When setting up the pump for use underwater, screw the
filter
1
onto the connection
2
at the inlet side of the pump.
– or –
When setting up the pump for use out of water, connect a
vacuum-resistant suction hose
3
with filter to the connec-
tion
2
at 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
4
are equipped with a 33.3 mm (G1”)
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.
v Connect the pressure hose

to the connector

on the
delivery side.
Only when setting up the pump for use out of water:
V Before each operation, fill the pump to overflowing
A with approx. 2 l of the liquid to be pumped !
1. Unscrew the screw fitting

by hand.
2. Fill the pump via the filler cap

to overflowing with approx.
2 l of the liquid to be pumped.
3. Tighten the screw fitting

by hand (do not
use pliers).
