Initial startup

Risk of electric shock and risk of injury!
The device contains electrical and mechanical components.
Always disconnect the device from the power supply before assembling, disassembling or cleaning.
Note
The shorter the hose length and larger the hose diameter, the higher the delivery rate.
To avoid clogging the pump, use a pre-filter for hose diameters smaller than 1 ¼'.

• SP 17.000 Flat Level Sensor: Accessories
• SP 22.000 Dirt Level Sensor: Integrated in the foot

The pump connection is equipped with a plug system (Quick-Connect).
The Connection nozzle with G 1 ½ pump connecting piece is supplied unmounted with the device.
Note
Hoses with a diameter of 1', 1 ¼' and 1 ½' can be connected to the pump connecting piece G 1 ½.
A sufficiently large hose diameter must be selected and the pump connecting piece must be shortened according to the grooves so that the required particle size can be used. A large hose diameter is also recommended for smaller particle sizes to allow a high flow volume.

Connecting the hose to the pump:

1. Screw the G 1 ½ pump connecting piece onto the connection nozzle.
   
2. Push the hose clamp onto the hose.
3. Push the hose onto the G 1 ½ pump connecting piece and fasten it with a hose clamp.
4. Push the connection nozzle into the Quick-Connect.
   

Erecting/immersing the pump:

1. Push the level sensor onto the rail from above.
   
2. Fold the feet out or in. (SP 17.000 Flat Level Sensor)
   
   Note
   The feet do not necessarily need for be folded out bit folding out the feet provides a higher delivery rate. Fold-ing the feet in allows flat suction of liquids to a residual fluid height of 1 mm.
3. Installing/removing the pre-filter. (SP 17.000 Flat Level Sensor)
   Illustration E
   Note
   It is not necessary to install the pre-filter, but a higher delivery rate is reached by installing the pre-filter (only for SP 17.000 Flat Level Sensor). The pumped liquid is pre-filtered by the pre-filter to protect the pump from heavy contamination. Particles of up to 5 mm can still be pumped when using the filter. Removing the pre-filter al-lows flat suction of liquids to a residual fluid height of 1 mm. (only for SP 17.000 Flat Level Sensor).
4. Place the pump securely on solid ground in the pumped liquid or immerse it via a rope attached to the carrying handle.
   Note
   The suction area must not be blocked by soiling. If the ground is muddy, place the pump on a brick or similar.
   Make sure that the pump stands level. Do not carry the pump using the cable or hose.

Operation

Danger of death from electric shock.
Danger of death from electric shock if live parts are touched.
During operation, do not touch the rope attached to the carrying handle or any objects that are in contact with the pumped liquid (e.g. pipelines protruding into the pumped liquid, railings) and do not reach into the pumped liquid.

Automatic venting device

1. If the fluid level is low, any sucked-in air, or air present in the pump, may escape via the automatic venting device. Fluid can also leak along with air.
   If the pump has problems with suction when the fluid level is low, unplug and plug in the mains plug repeatedly to assist the suction process.
   

Automatic mode

Note
In automatic mode, the level sensor controls the pumping process automatically. The pump switches on when the level sensor makes contact with the rising pumped liquid.
The pump switches off when the level sensor loses contact with the falling pumped liquid and an after-running time of 15 s has expired.

Switching on:
Minimum fluid level required to enable the pump to suck independently (= minimum switch-on point):

• SP 17.000 Flat Level Sensor: 7 mm (57 mm when using the pre-filter)
• SP 22.000 Dirt Level Sensor: 50 mm

Highest adjustable switching height of the level sensor:

• SP 17.000 Flat Level Sensor: 190 mm (240 mm when using the pre-filter)
• SP 22.000 Dirt Level Sensor: 237 mm

Minimum residual fluid height/max. suction depth:

• SP 17.000 Flat Level Sensor: 1 mm (without pre-filter, with folded feet)
• SP 22.000 Dirt Level Sensor: 35 mm

Note
It is recommended to use the pre-filter.
Note
Make sure that the pump stands level. Otherwise the level sensor may not lose contact with the fluid and the pump can run dry.

1. Push the level sensor to the desired switch-on height (contact with the pumped liquid).
   Note
   The higher the level sensor is set, the higher the switchon and switch-off points. See the following table for application examples:

   Application area	SP 17.000 Flat Level Sensor	SP 22.000 Dirt Level Sensor
   Shafts with a diameter < approx. 1 m (e.g. drainage)	Level sensor in uppermost position	Level sensor in uppermost position
   	We recommended using the pre-filter	Pre-filter flap closed (protection against soiling)
   Swimming pools, ponds (only for SP 22000 Dirt Level Sensor)	Level sensor in lowest position	Level sensor in lowest position
   	Starting pumping with the pre-filter or folded-out feet	Pre-filter flap closed (protection against soiling)
   	Continuing pumping without the pre-filter and folded-in feet (reaches a residual fluid height of 1 mm) Note Perform in manual mode. Monitor the switch-off/ shallow suction.

2. Set the switch to Automatic mode (AUTO).
   
3. Plug the mains plug into a mains socket.

Manual mode

Note
In manual mode, the pump stays switched on.

1. Set the switch to Manual mode (MAN).
   Illustration H
2. Plug the mains plug into a mains socket.

ATTENTION
Risk of damage from dry running!
Dry running leads to increased wear on the pump.
Do not leave the pump unattended in manual operation. In case of dry running, immediately pull the mains plug out of the socket.

Flat suction (SP 17.000 Flat Level Sensor)

It is recommended to use manual mode to reach the min. residual fluid height of 1 mm.
A check valve is installed in the SP 17.000 Flat Level Sensor. This prevents residual fluid in the hose from flowing back after the pumping process finishes.

Finishing operation

1. Pull the mains plug out of the socket. The device stops.
   ATTENTION
   Risk of damage!
   Risk of damage due to dried soiling or additives.
   Rinse and clean the device immediately after each use.
2. If dirty liquids or liquids with additives have been pumped, rinse and clean the device immediately after finishing operation, see chapter Rinsing and cleaning.
3. Drain the device and accessories and let them dry.

Troubleshooting guide

Malfunctions often have simple causes that you can remedy yourself using the following overview. When in doubt, or in the case of malfunctions not mentioned here, please contact your authorised Customer Service.

Technical data

Subject to technical modifications.

Optimising the flow rate

The flow rate is further increased:

• The lifting height is reduced.
• The diameter of the hose used is increased.
• The length of the hose used is decreased.
• The smaller the pressure loss caused by the connected up accessories.
