Initial startup

DANGER : 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 17000 Flat Level Sensor: Accessories
SP 22000 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

½ pump connecting piece onto the connection nozzle. Illustration B
Push the hose clamp onto the hose.
Push the hose onto the G 1 ½ pump connecting piece and fasten it with a hose clamp.
Push the connection nozzle into the Quick-Connect. Illustration C

Erecting/immersing the pump:

1 Push the level sensor onto the rail from above. Illustration D
Fold the feet out or in. (SP 17000 Flat Level Sensor) Illustration E

Note The feet do not necessarily need for be folded out bit folding out the feet provides a higher delivery rate. Folding the feet in allows flat suction of liquids to a residual fluid height of 1 mm. 3 Installing/removing the pre-filter. (SP 17000 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 17000 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 allows flat suction of liquids to a residual fluid height of 1 mm. (only for SP 17000 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
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
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. Illustration F

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.

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

SP 17000 Flat Level Sensor: 7 mm (57 mm when using the pre-filter)
SP 22000 Dirt Level Sensor: 50 mm

Highest adjustable switching height of the level sensor:

SP 17000 Flat Level Sensor: 190 mm (240 mm when using the pre-filter)
SP 22000 Dirt Level Sensor: 237 mm

Minimum residual fluid height/max. suction depth:

SP 17000 Flat Level Sensor: 1 mm (without pre-filter, with folded feet)
SP 22000 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.

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 17000 Flat

2. Set the switch to Automatic mode (AUTO). Illustration H

Plug the mains plug into a mains socket.

Manual mode

Note In manual mode, the pump stays switched on.

Set the switch to Manual mode (MAN). Illustration H
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 17000 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 17000 Flat Level Sensor. This prevents residual fluid in the hose from flowing back after the pumping process finishes.

Finishing operation
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.

Care and maintenance

DANGER: Risk of electric shock and risk of injury! The device contains electrical and mechanical components. Cleaning and user maintenance may not be carried out by children.

Rinsing and cleaning

ATTENTION: Risk of damage! Risk of damage due to dried soiling or additives. Rinse and clean the device immediately after each use. 1 If dirty liquids or liquids with additives have been
