  2. Carrying handle
  3. Power cord with plug
  4. Rail (level sensor)
  5. Level sensor
  6. Automatic venting device
  7. Quick-Connect

  10. Pre-filter

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 freshwater.
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

DANGER
Risk of injury, risk of damage! Caustic, slightly inflammable, and other explosive substances (such as petrol, petroleum, diluted nitrogen), greases, oils, saltwater, 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, slide down the prefilter with hose diameters of less than 1¼ “.
The pump connection is equipped with a plug system (Quick-Connect).
The unmounted connection nozzle with the pump connecting piece is enclosed in the device.
Illustration A

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

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.).

General

Illustration E
NOTICE
The fluid level must be at least 50 mm for the pump to draw independently.
The pump can pump up to a residual fluid height of 35 mm.

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 E
NOTICE
In the automatic mode, the level sensor automatically controls the pumping operations.
As soon as the level sensor has contact with the rising feed fluid the pump switches on.
The pump switches off as soon as the level sensor loses contact with the falling feed fluid and an after-running time of 15 s has passed.
For switch-on height / switch-off height see the following table:

Switch-on points SP 7 Dirt Inox
Depending on the position of the level sensor 55 – 240mm

NOTICE
Ensure that the pump is level.
Otherwise, it can happen that the level sensor does not lose the fluid contact and the pump runs dry.

NOTICE
The higher the level sensor is adjusted, the higher the switch-on and switch-off point.
See the following table for application examples:

Min/Max SP 7 Dirt Inox
Shaft with a diameter < of approx.
1 m (e.g. drainage)
Level sensor in the upmost position
Pre-filter flaps closed (protection against soiling)
Swimming pool, pond, or the like Level sensor in the lowest position
Pre-filter flaps closed (protection against soiling)

Finish operation

NOTICE
Soiling can deposit and lead to malfunctions.

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).

Troubleshooting

DANGER
Risk of mortal danger on account of electric shock!
To avoid risks, all repairs and replacement of spare parts may only be carried out by the authorized customer service personnel.

Fault Cause Remedy
The pump runs but does not transport Air in the pump Unplug and plug in the mains plug of the pump repeatedly until the fluid is drawn
Suction area blocked Pull out the mains plug and clean the suction area
Water level below the minimum fluid level Immerse, whenever possible, the pump deeper into the feed fluid or pro­ceed as described in Chapter Opera­tion.
The pump does not run or suddenly comes to a standstill during operations Power supply interrupted Check fuses and electrical connec­tions
The thermal protection switch has switched off the pump due to over-heating Pull out the mains plug, let the pump cool down, clean the suction area, and prevent dry running
Dirt particles have got jammed into the suction area Pull out the mains plug and clean the suction area
The level sensor stops the pump Check the position of the level sensor and correct it if necessary.

The pump stops 15 s after the level sensor has no water contact anymore.

The level sensor does not react as it is soiled Clean the level sensor.
Pumping capacity is reducing Suction area blocked Pull out the mains plug and clean the suction area
Pumping capacity too low The pumping capacity depends on the flow height, hose diameter, and hose length. Observe the maximum delivery height, see technical data. If neces­sary, use a larger hose diameter or a shorter hose length.
Quick-Connect cannot be opened or closed. Soiling in the plug system. Remove and clean the clip.
The pump is running although there is no water contact with the level sensor The level sensor does not react as it is soiled Clean the level sensor.
The switch is on the manual operation (MAN) Set the switch to automatic mode (AU-TO).
