Start up
NOTICE
The shorter the hose length and the larger the hose di-
ameter, the higher the pump capacity.
To prevent clogging of the pump, use a prefilter with
hose diameters of less than 1¼ ".
 SP 5 Dirt, special accessories
 SP 7 Dirt, integrated in the base
The pump connection is equipped with a plug system
(Quick-Connect).
The unmounted connection nozzle (SP 5 Dirt) or the
connection nozzle with pump connecting piece (SP 7
Dirt) is enclosed in the device.
Illustration
 To remove the connection nozzle, press the Quick-
Connect (grey button).
Illustration
(SP 5 Dirt)
 Slide the hose clamp onto the hose.
If a ¾" or 1" hose is used:
 Screw pump connecting piece (see special acces-
sory) 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.
NOTICE
To increase the flow volume, the pump connecting
piece can be shortened according to the hose used.
If a 1¼ " hose is used:
 Slide the hose onto the connection nozzle and se-
cure by means of a hose clamp.
 Slide the connection nozzle into the Quick-Connect.
Illustration
(SP 7 Dirt)
 Screw the pump connecting piece onto the connec-
tion 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 con-
nected to the pump connecting piece.
To increase the flow volume, the pump connecting
piece can be shortened according to the hose used.
Illustration
 Snap the float switch into the height adjustment.
 Safely place the pump on a stable surface in the
feed fluid or immerse it using a rope tied to the car-
rying 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 carry-
ing handle as well as objects that are in contact with the
feed fluid (e.g. pipelines extending into the water, rail-
ings, etc.).
Automatic venting device
Illustration
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
 Adjust the float switch via the height adjustment
and the cable length between float switch and
height adjustment.
NOTICE
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 level.
Ensure that the float switch is not obstructed in any way.
The cable between the float switch and the lock must be
at least 2.5 cm long.
Switch-on height / switch-off height (float switch in
the lowest position):
Min / Max
Switch-on height

Switch-off height

Switch-on height / switch-off height (float switch in
the upmost position):
Min / Max

Switch-off height

*The switching height can vary depending on the posi-
tion of the float switch.
Likewise, the cable length between the float switch and
the lock can influence the switching heights. We recom-
mend retaining the preset cable length.
 Insert the mains plug into the socket.
Illustration
 Secure the nose on the float switch into the open-
ing of the lock pointing up.
NOTICE
In manual operation the pump remains switched on
continuously.
In order that the pump draws independently in manual
operation, the fluid level must be at least 60 mm (SP 5
Dirt) or 50 mm (SP 7 Dirt).
The pump can pump up to a residual fluid height of
25 mm (SP 5 Dirt) or 35 mm (SP 7 Dirt).
The stated residual fluid height is only achieved in man-
ual operation.
 Insert the mains plug into the socket.
ATTENTION
Risk of damage! Dry running leads to increased wear;
never leave the pump unattended during manual oper-
ation. Switch off immediately in case of dry running.
