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
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)

(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.
