Pointer to a possibly dangerous situation, which can lead to mi-nor injuries.
Pointer to a possibly dangerous situation, which can lead to property damage.

Electric components

Risk of electric shock.

  • Check the power cord with mains plug for damage be-fore every use. If the power cord is damaged, please arrange immediately for the ex-change by an authorized customer service or a skilled electrician.
  • Install all electrical plug connections in a flood-proof area.
  • Unsuitable electrical extension cables can be hazardous. Only use electrical ex-tension cables that have been approved and labelled for this purpose and have an adequate cable cross-section outdoors.
  • The mains plug and the coupling of an extension cable must be watertight and must never lie in water. Moreover, the coupling may never lie on the ground. The use of cable reels that ensure that the sockets are at least 60 mm above the ground is recommended.
  • Do not use the power cord to carry/ transport the machine.
  • To separate the machine from the mains, pull the plug and not the power cord.

  • The voltage indicated on the type plate must correspond to the voltage of the electrical source.
  • To avoid risks, all repairs and replacement of spare parts may only be carried out by the authorized customer service personnel.
  • Operate pumps only on sockets that are equipped with a fault current protection switch with a nominal fault current of max. 30 mA and a protective-earth contact (earthing).
  • Check the fault current protection switch and the protective earth contact (earthing) for proper function at regular intervals.
  • Never operate the pumps while there are persons in the pool or garden pond.
  • In Austria pumps to be used in swimming pools and gar-den ponds should be equipped with a fixed connection line according to ÖVE B/EN 60555 Part 1 to 3; power supply should be via a ÖVE-tested isolating transformer whereby the secondary nominal voltage should not exceed 230V.
  • The electrical connection of the system may only be per-formed by a qualified electrician. Please follow the respective national regulations!

Description of the Appliance

  1. Carrying handle
  2. Power cord with plug
  3. Lock (float switch)
  4. Swimmer switch
  5. Quick-Connect
  6. Automatic venting device
  7. Connection nozzle (1¼“ hose connection and G1 thread)

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.
The device is not suitable for continuous pump operation (e.g. continuous circulation in a pond) or as a stationary installations (e.g. lifting device, fountain pump).

Approved feed fluids
  • Fresh water up to a certain degree of soiling
  • Water from swimming pool (provided the dosing of additives is proper)
  • Washing lye
  • Water with a degree of contamination up to a grain size of 20 mm

Risk of injury, risk of damage! Caustic, slightly inflammable and other explosive substances (such as petrol, petroleum, diluted nitrogen), greases, oils, salt water and waste water 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 de-livered fluid must be between 5 °C and 35 °C.

Start up

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 “ (see special accessories).
The pump connection is equipped with a plug system (Quick-Connect).
The unmounted connection nozzle is enclosed in the device.

To remove the connection nozzle, press the Quick-Connect (grey button).


  • Slide the hose clamp onto the hose.
    If a ¾“ or 1“ hose is used:
  • Screw 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.
    If a 1¼ “ hose is used:
  • Slide the hose onto the connection nozzle and secure by means of a hose clamp.
  • Slide the connection nozzle into the Quick-Connect.
  • Safely place the pump on a stable surface in the feed fluid or immerse it using a rope tied to the carrying handle.

The suction area must not be blocked by soiling.
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.


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

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

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 lev-el.
Ensure that the float switch is not obstructed in any way. For switch-on height / switch-off height see the following table:

Min / Max           SP 3 Dirt
Switch-on height    43 / 50
Switch-off height   18 / 30

*The switching height can vary depending on the position of the float switch.
Insert the mains plug into the socket.

Manual operation


Secure the float switch pointing upwards in the lock.

In manual operation the pump remains switched on continuously.
The fluid level must be at least 60mm for the pump to draw independently in the manual mode.
The pump can pump up to a residual fluid height of 25 mm.
The stated residual fluid height is only achieved in manual operation.

Insert the mains plug into the socket.
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

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 residue.
  • Disconnect the main plug from the socket.


The pump is maintenance free.


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.


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

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