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

In Austria

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

In Switzerland mobile appliances which are used outdoors,

must be connected via a residual-current device.

Mains power

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.

Visual check

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.

Note on use

v Clear the outlet line before use.

When setting up the pump for use out of water

Dry-Running

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 !

Liquid fails to flow

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.

If liquid fails to flow, switch off the pump immediately.

Minimum flow rate

The minimum flow rate is 80 l / h (= 1.3 l / min).

Watering accessories with lower rate must not be operated.

Hot water –

If the pump is operated for prolonged periods of time (> 5 min)

risk of scalding

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.

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.

Best results regarding the delivery capacity of the pump are

achieved when connecting 19 mm (3 / 4") hoses in conjunction

with e.g.

or when using 25 mm (1") hoses with fittings available from your

sanitary dealer.
