1. Clean the pump housing with a damp cloth.

2. Clean the airflow slots with a soft brush (do not use sharp objects).

4.2 To flush the pump:

After pumping chlorinated water, the pump must be flushed.

1. Pump through lukewarm water (max. 35 °C), possibly adding a mild

cleaning agent (e. g. detergent) until the pumped water runs clear.

2. Dispose of the residues in accordance with local waste disposal

regulations.

5. STORAGE

5.1 To put into storage [ Fig. S1 ]:

CAUTION!

Damage to the pump due to frost!

v Store the pump in a frost-free place.

The product must be stored away from children.

1. Unplug the plug of the mains cable from the mains socket.

2. Close any shut-off valves in the suction line.

3. Open any shut-off valves in the pressure line (accessories, water

stop, etc.).

Therefore the pressure line is depressurized.

4. Unscrew the screw fitting

of the filler neck

screw

by hand.

Therefore the pump is drained.

5. Tilt the pump in the direction of the drain (approx. 80°) so that the

pump empties completely.

6. Unscrew the suction hose and the pressure hose.

7. Tighten the screw connection

using GARDENA Suction Hoses (see 8. ACCESSORIES /

doesn't take place

SPARE PARTS).

Screw fitting on the filler neck

is leaking [ Fig. A2 ].

Air cannot escape, since the

delivery line is closed or

remaining water is in the

pressure hose.

Air cannot escape because the

pressure hose is coiled.

Suction time of 5 min. was

not waited for.

Suction filter or backflow

preventer in the suction hose

are clogged.

The end of the suction hose is

not in the water [Fig. A5].

Suction height is too high

[Fig. A5].

In case of any other difficulties concerning the suction action,

use GARDENA Suction Hoses with Backflow Preventer

(see 8. ACCESSORIES / SPARE PARTS). Fill the pump with

water before starting it.

Pump does not start,

Thermal switch has turned

or stops suddenly during

the pump off because of over

operation

heating.

No power supply to the pump.

RCD has triggered

(residual current).

Pump is not switched on.

drops suddenly

Suction filter or backflow

preventer in the suction hose

are clogged.

No water available in the
