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

Freshwater up to a certain degree of soiling
Water from the swimming pool (provided the dosing of additives is proper)
Washing lye
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, 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.

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.

Push the level sensor to the desired switch-on height (contact with feed fluid).

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