Proper use
This appliance has been designed for use in private households and is not intended for commercial use. The manufacturer is not responsible for any damages that may occur on account of improper use or wrong operations. The device is mainly intended for draining building parts in case of flooding, but also for pumping over or out containers, for water removal from wells and shafts as well as for draining water from boats and yachts, provided that it is fresh water.
NOTICE
The device is not suitable for continuous pump operation (e.g. continuous circulation in a pond) or as a stationary installation (e.g. lifting device, fountain pump).

Approved feed fluids

• Freshwater up to a certain degree of soiling

• Water from the swimming pool (provided the dosing of additives is proper)

•  Washing lye
  SP 5 Dirt

• Water with a degree of contamination up to a grain
  size of 20 mm
  SP 7 Dirt

• Water with a degree of contamination up to a grain
  size of 30 mm

DANGER
Risk of injury, risk of damage! Caustic, slightly inflammable, and other explosive substances (such as petrol, petroleum, diluted nitrogen), greases, oils, salt water, and wastewater from toilets as well as sludgy water that has a slower flow capacity than water, must not be transported with this pump. The temperature of the delivered fluid must be between 5 °C and 35 °C.

Startup
NOTICE
The shorter the hose length and the larger the hose diameter, the higher the pump capacity.
To prevent clogging of the pump, use a prefilter with hose diameters of less than 1¼ “.

• SP 5 Dirt, special accessories

•  SP 7 Dirt, integrated into the base
  The pump connection is equipped with a plug system (Quick-Connect).
  The unmounted connection nozzle (SP 5 Dirt) or the connection nozzle with pump connecting piece (SP 7 Dirt) is enclosed in the device.
  Illustration A

• To remove the connection nozzle, press the QuickConnect (grey button).
  Illustration B

(SP 5 Dirt)

• Slide the hose clamp onto the hose.
  If a ¾“ or 1“ hose is used:

• Screw the pump connecting piece (see special accessory) onto the connection nozzle.

• Slide the hose onto the pump connecting piece and secure it by means of a hose clamp.

• Slide the connection nozzle into the Quick-Connect.

NOTICE

To increase the flow volume, the pump connecting piece can be shortened according to the hose used.

If a 1¼ “ hose is used:

• Slide the hose onto the connection nozzle and secure it by means of a hose clamp.

• Slide the connection nozzle into the Quick-Connect.
  Illustration C
  (SP 7 Dirt)

• Screw the pump connecting piece onto the connection nozzle.

• Slide the hose clamp onto the hose.

• Slide the hose onto the pump connecting piece and secure it by means of a hose clamp

• Slide the connection nozzle into the Quick-Connect.

NOTICE
Hoses with a diameter of 1“, 1¼“, and 1½“ can be connected to the pump connecting piece.
To increase the flow volume, the pump connecting piece can be shortened according to the hose used.
Illustration E

• Snap the float switch into the height adjustment.
• Safely place the pump on a stable surface in the feed fluid or immerse it using a rope tied to the carrying handle.

NOTICE
The suction area must not be blocked by soil.
In case of muddy ground, place the pump on a brick or the like.
Ensure that the pump is level.
Do not carry the pump on the cable or the hose.

Operation

DANGER
Risk of mortal danger on account of electric shock!
Do not touch feed fluids, the rope attached to the carrying handle as well as objects that are in contact with the feed fluid (e.g. pipelines extending into the water, railings, etc.).
Automatic venting device
Illustration D
With a low fluid level, possibly drawn air or air that is present in the pump escapes via the automatic venting device. In addition, fluid may leak at this spot.  If the pump has suction problems with a low fluid level, unplug and plug in the mains plug repeatedly in order to support the suction process.

Automatic operation

Illustration G

• Adjust the float switch via the height adjustment and the cable length between the float switch and height adjustment.
  NOTICE
  In the automatic mode, the float switch controls the pumping operations automatically.
  The pump switches on as soon as the float switch has reached the switch-on height due to the rising fluid level. The pump switches off as soon as the float switch has reached the switch-off height due to the falling fluid level. Ensure that the float switch is not obstructed in any way. The cable between the float switch and the lock must be at least 2.5 cm long.
  Switch-on height / switch-off height (float switch in the lowest position):

Switch-on height / switch-off height (float switch in
Min / Max| SP 5 Dirt| SP 7 Dirt
Switch-on height| 28 / 31 cm| 33 / 36 cm
Switch-off height| 14 / 22 cm| 19 / 27 cm

*The switching height can vary depending on the position of the float switch.
Likewise, the cable length between the float switch and the lock can influence the switching heights. We recommend retaining the preset cable length.

• Insert the mains plug into the socket.

Manual operation

Illustration F

• Secure the nose on the float switch into the opening of the lock pointing up.
  NOTICE
  In manual operation, the pump remains switched on continuously.

• In order that the pump draws independently in manual operation, the fluid level must be at least 60 mm (SP 5 Dirt) or 50 mm (SP 7 Dirt).

The pump can pump up to a residual fluid height of 25 mm (SP 5 Dirt) or 35 mm (SP 7 Dirt).
The stated residual fluid height is only achieved in manual operation.

• Insert the mains plug into the socket.
  ATTENTION
  Risk of damage! Dry running leads to increased wear;
  never leave the pump unattended during manual operation. Switch off immediately in case of dry running.

Finish operation

NOTICE
Soiling can deposit and lead to malfunctions.

• Pump clear water or thoroughly rinse the pump after every use.
  This especially applies after pumping chlorinated water or other liquids that leave a residue.

• Disconnect the main plug from the socket.

Maintenance

The pump is maintenance-free.

Transport
CAUTION
In order to prevent accidents or injuries, keep in mind the weight of the appliance during transport (see Specifications).

• Lift and carry the pump on the carrying handle.
• If you want to transport the appliance on a vehicle secure it from slipping.

Storage
CAUTION
In order to prevent accidents or injuries, keep in mind the weight of the appliance when selecting a storage location for it (see Specifications).

Storing the pump

• Completely drain the pump and allow it to dry.
• Store the pump in a frost-free place.
