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 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, e.g. leaked washing machine load. Then clean with clear water.
Sp 7 Dirt Inox (wastewater pump)
Water with a degree of contamination up to a grain size of 30 mm
SP 6 Flat Inox (clean water pump)
Water with a impurities up to a maximum grain size of 5mm

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 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 delivered fluid must be between 5 °C and 35 °C.

Start up

NOTICE The shorter the hose length and the larger the hose diameter, the higher the pump capacity. In order to prevent the pump from clogging, use the enclosed pre-filter (SP 6 Flat Inox) or slide down the integrated pre-filter (SP 7 Dirt Inox) with hose diameters of less than 1¼ “. The pump connection is equipped with a plug system (Quick-Connect). The unmounted connection nozzle with pump connecting piece is enclosed in the device.
Illustration A

To remove the connection nozzle, press the QuickConnect (grey button).
Illustration B
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. 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.
Illustration C
Slide the level sensor onto the rail from the top.
Illustration D
Fold out or fold in the support legs (SP 6 Flat Inox) for the pump start.
NOTICE
It is not mandatory to fold out the support legs; a higher pump capacity is achieved by folding out the support legs.
Folding in the support legs enables the flat vacuuming of the fluid up to a residual fluid height of up to 1 mm.
Install or uninstall pre-filter (SP 6 Flat Inox).
Slide down or up the pre-filter (SP 7 Dirt Inox).
NOTICE It is not necessary to install the pre-filter, but a higher pump capacity is reached by installing the pre-filter (only for SP 6 Flat Inox). The feed fluids are pre-filtered by the pre-filter to protect the pump from heavy contamination. Particles up to 5 mm can still be used in the filter. Disassembly of the pre-filter allows for the flat vacuuming of the fluid up to 1 mm residual fluid height (SP 6 Flat Inox).
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 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.

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 F
NOTICE
In order for the pump to draw independently, the fluid level must be at least 50 mm (SP 7 Dirt Inox) or 7 mm (SP 6 Flat Inox). The pump can pump up to a residual fluid eight of 35 mm (SP 7 Dirt Inox) or 1 mm (SP 6 Flat Inox).
Automatic venting device
Illustration E
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 F
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.

Switching on:
Minimum fluid level required to enable the pump to suction independently (=minimum switch-on point): SP 6 Flat Inox: 7 mm (57 mm when using the pre-filter) SP7 Dirt Inox: 50mm

Highest adjustable switching height of the level sensor:
SP 6 Flat Inox: 190 mm without pre-filter (240 mm when using the pre-filter) SP 7 Dirt Inox: 237 mm

Minimum residual fluid height/max. Extraction depth:
The pump can pump out up to a residual liquid height of SP 6 Flat Inox: 1 mm (without pre-filter, with folded base) SP 7 Dirt Inox: 35 mm

NOTICE
It is recommended to use the pre-filter.

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:

Min / Max	SP 6 Flat Inox	SP 7 Dirt Inox
Shaft with a diame- ter < of approx. 1 m (e.g. drainage)	Level sensor in the upmost po- sition	Level sensor in the upmost position
Shaft with a diame- ter < of approx. 1 m (e.g. drainage)	It is recom- mended to use the pre-filter.	Pre-filter flaps closed (protection against soiling)
Float basin, pond (only SP 7 Flat In- ox) or something similar	Level sensor in the lowest posi- tion	Level sensor in the lowest position
	Start pumping operations with pre-filter or folded out sup- port legs	Pre-filter flaps closed (protection against soil-ing)
	Continuation pumping operations without pre-filter and folded in support legs (residual fluid height 1 mm is reached) Note Perform in manual mode. Check the switch-off/shallow suction.	–

Set the switch to automatic mode (AUTO).
Insert the mains plug into the socket.

Manual operation

NOTICE
In manual operation the pump remains switched on continuously.
Illustration G
Set the switch to manual operation (MAN).
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. Unplug immediately in case of dry running

Flat vacuuming (SP 6 Flat Inox)
It is recommended to use manual mode to reach the min. residual fluid height of 1 mm. A check valve is installed for the SP 6 Flat Inox. This prevents residual fluid in the hose from flowing back after the pumping process finishes.

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 residue.
Disconnect the main plug from the socket.

Maintenance

The pump is maintenace-free.
