Circuit breakers Thermal protection switch: In the event of an overload, the pump is switched off by the built-in thermal motor protection. After sufficient cooling of the motor, the pump is operational again. Automatic venting This pump is equipped with a vent valve which eliminates any air pockets in the pump. Depending on the function, asmall amount of water can escape from the side of the housing. Additional safety warnings Electrical safety DANGER! Cardiac arrest! This product makes an electromagnetic field while it operates. This field may under some conditions interfere with active or passive medical implants. To decrease the risk of conditions that can possibly injure or kill, we recommend persons with medical implants to speak with their physician and the medi- cal implant manufacturer before you operate the product. Cables If extension cables are used, these must comply with the minimum cross-sections in the table below: Voltage Cable length Cross section 230 – 240 V / 50 Hz Up to 20 m 1.5 mm

DANGER! Electric shock! With a cut off mains plug, moisture can get into electrical parts via the mains cable and cause ashort circuit. v Never cut the mains plug off (e. g. to feed through wall). v Don’t use the power cable for plugging off. v If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. Mains plug and extension connections must be protected from water splashes. Ensure that the electrical connections for plugs and sockets are made in areas safe from flooding. Protect the mains plug and the mains power cable from heat, oil and sharp edges. Observe the mains voltage. The information on the name- plate must be in agreement with the data for the mains power grid. The pump’s mains plug must be disconnected before anybody enters the swimming pool or touching the sur- face of the water. The mains power cable must not be used for fastening or transporting the pump. For submerging or lifting / securing the pump, please use a fastening rope. Please regularly check the connecting line. Before using, always subject the pump (especially the power cables and the power connections) to a visual inspection. A pump which is damaged should not be used. In the event of damage, have the pump checked by the GARDENA Service. Assembly instructions: Retighten all screws by hand. Before use after maintenance, make sure that all parts are screwed together. When using our pumps with a generator, the warnings of the generator manufacturer must be observed. Personal safety

DANGER! Risk of suffocation! Small parts can be easily swallowed. There is also arisk that the polybag can suffocate toddlers. Keep toddlers away when you assemble the product. Observe the minimum water level in accordance with the characteristics given for the pump. Allow the pump to run no longer than 10 minutes against a closed pressure side. Sand and other abrasive substances cause increased wear and reduce the pump’s output. The sensor fields may may only be operated outside the water. The hose must not be disconnected during operation. Allow the pump to cool down before troubleshooting.

DANGER! Risk of physical injury! Injury when the product starts accidentally. v Disconnect the product from the mains before you assemble the product. Connection possibilities of the connection nipple [ Fig. A1 ]: The hose can be connected via the connection nipple

Injury when the product starts accidentally. v Disconnect the product from the mains before you connect, adjust or transport the product. To pump water: If the pump cannot be immersed via the handle, the pump must always be immersed via a rope. Attach the rope by pulling it through the eyelets provided and knotting it. Minimum immersion depth during initial operation see 7.TECHNICAL DATA. Take care that the pump is located where the inlet open- ings at the suction base are not obstructed neither com- pletely nor partly. Stand the pump on a brick if using in a pond. If the suction process is close to the minimum water level at start-up, the suction process may take longer.

1. Immerse the pump.

2. Connect the pump to the mains.

Attention! The pump begins operating immediately. The sensor is initialised and indicated by a running light. Large hose diameter Cut off nipple at

• For Art. 9034 an additional connection nipple

for 11/4" hoses is supplied. To connect the hose via the connection nipple:

1. When using the large diameter hose, cut off the con-

hose diameter, cut off the connection nipple

3. Push the hose onto the connection nipple

4. Fix the hose to the connection nipple

on the elbow connector

With Art. 9034 / 9036 a non-return valve is supplied which prevents water from flowing back through the hose. The max. delivery rate is only achieved without the non-return valve. If only a small amount of reflux is expected, e. g. if the hose is laid flat, we recommend dispensing with the valve due to the better delivery and suction performance.

into the pump. Observe the installation direction.

2. Screw the elbow connector

clockwise into the pump until it stops. (If the hose is to be installed horizontally, the elbow connector

can be screwed out again up to half a turn. When using the non-return valve, increased force is required.)

3. Screw the connection piece

into the connection nipple

of the hose into the elbow connector

until it stops until it engages audibly and visibly. The hose is securely connected to the pump.

1. Disconnect the pump from the mains.

2. Turn the pump upside down until no more water runs

4. Store the pump in a dry, enclosed and frost-free place.

Automatic operation [ Fig. O1 ]: In automatic operation the pump switches on automatically when the water level reaches the switch-on level and switches off automatically when the water level reaches the switch-off level. Switch-on / switch-off heights of the sensor fields: The sensor has nine sensor fields (

from bottom to top), which are located to the right of the LEDs. The sensor fields are about 1 cm high (no finger or changed water level is detected between the sensor fields). Sensor field

Art. 9034 / 9036: When the feet are folded in, the values are 4 mm higher in each case. After plugging in the pump the 9 LED’s light up one after the other. The pump starts at the factory in automatic mode with sensor field switch-on height

and sensor field switch-off height

To adjust the switch-on / switch-off heights [ Fig. O1 ]: The sensor fields can only be adjusted outside the water. When the pump has been removed from the water, the sensor should be dried for programming. The upper sensor field is always the switch-on height, the lower sensor field is always the switch-off height.

1. Operate the sensor field until the input is acknowledged

with a short double flash of all LEDs.

2. Keep the sensor field

pushed until the double flash- ing of all LED's has acknowledged the input. The currently set switch-on and switch-off heights are briefly displayed. After that all sensor fields light up.

3. Push the desired upper sensor field for the switch-on

height. The LED of the selected sensor field switches off.

4. Push the desired lower sensor field for the switch-off

height. The LED of the selected sensor field switches off. After 3 seconds, the set switch-on and switch-off heights are accepted and displayed. Automatic clear water suction for very low water levels: Sensor field

can be selected both as switch-on and switch-off point. If the sensor field

still detects water within 10 minutes after starting the pump, the pump switches off to prevent damage due to dry running. The pump will still start if sensor field

detects water. In this case, however, the sensor should be cleaned to ensure exact water level detection. If the sensor field

is activated several times within ashort time by water flowing back from the hose line, there is a pause of 10 minutes. If the water level reaches sensor field

, the pump switch- es on automatically, even within the pause of 10 minutes. If this is the case regularly, please select the next sensor field as the switch-on point. In order to ensure quick suction, the pump switches off briefly for the sensor field

to vent. After 20 seconds of operation, the pump switches off once for approx. 2 seconds and then on again. To display switch-on and switch-off heights: v Keep the sensor field

pushed until the double flash- ing of all LED's has acknowledged the input. The currently set switch-on and switch-off heights are displayed. Disable the water level tracking: In automatic operation, the LEDs follow the water level. This can be deactivated. v Keep the sensor field

pushed during initialisation until the double flashing of all LED's has acknowledged the input (see To pump water). To switch the water level tracking back on, push and hold the sensor field

again during initialisation until the double flashing of all LED's has acknowledged the input. Demo mode: For presentation purposes, the pump can be put into demo mode. In this mode, the LEDs simulate the pump’s functions via flashing sequences and the sensor fields react to touch. v Keep the sensor fields

pushed during initiali- sation when switching on or during the self-test after plugging in until the double flashing of all LED’s has acknowledged the input. To switch off the demo mode again, push and hold the sensor fields

during initialisation when switching on or during the self-test after plugging in until the double flashing of all LED's has acknowledged the input. Manual operation [ Fig. O1 ]: In manual mode the pump runs until the pump is discon- nected from the mains. This mode is particularly suitable for flat suction. In manual operation the sensor fields are deactivated. The pump then runs until the pump is disconnected from the mains or another operating mode is selected. v Keep the sensor fields

pushed until the double flashing of all LED’s has acknowledged the input. All LEDs will light up and within 5 seconds all the LEDs will switch off one after the other. The pump starts. During these 5 seconds the pump should be placed in the water. A start will only take place if the pump detects water. If this is not the case, the countdown is repeated up to three times. If you need more time to put the pump into the water, please disconnect the pump from the power supply. The countdown will continue after the sensor is plugged in again.
