4. INTENDED USE
The SUBSON series drainage and submersible waste water
pumps are used:
•for the automatic drainage of pits and shafts,
•for keeping dry yard areas and basement rooms exposed to
flooding,
•for lowering surface water,
if the waste water is not able to flow off into the sewer system
through natural fall.
The pumps are suitable for pumping slightly contaminated
water, rainwater, drainage water and washing water.
"AB" pumps versions are intended for pumping down to 2mm
suction level from the floor. This version is recommended for
mobile installation and pumping clear water.
The pumps are usually installed under water (submerged) and
can only be permanently or transportably installed vertically.
Because of the sheath current cooling, the pumps can also be
operated unsubmerged.
Submersible pumps with a mains connection cable of less than
10 metres are (according to EN 60335) only permitted for use
inside buildings, i.e. not for operating outside.
Pumps that are intended for use in or at garden ponds or similar
places must have a mains connecting cable that is not lighter
than rubber sheathed cables reference H07 RN-F (245 IEC 66)
according to EN 60335.
Danger! Mortal danger due to electric shock
The pump many not be used to drain swimming pools /
garden ponds or similar places if anyone is in the water.
WARNING! Hazardous to health!
Owing to the materials used, the pumps are not suitable
for potable water! Unpurified foul and waste water rep-
resents a health hazard.
CAUTION! Danger of property damage!
Pumping unpermitted substances can lead to product
damage.
The pumps are not suitable for water with coarse con-
tamination such as sand, fibres or combustible, caustic
fluids or for use in potentially explosive areas.
Correct use of the pump/unit also includes following these
instructions.
Any use over and beyond these is interpreted as incorrect use.
