3. Transport and interim storage
As soon as the product arrives:
• Check the product for damage in transit,
• In the case of transport damage, initiate the nec-
essary procedures with the forwarding agent
within the time stipulated.
CAUTION! Danger of property damage!
Incorrect transport and incorrect intermediate
storage can lead to product damage.
• The pump may only be suspended/carried by the
strap provided for transport purposes. The cable
should never be used for lifting!
• The pump must be protected against moisture,
frost and mechanical damage when transported
and stored.
4. Intended use
The Drain TM 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 con-
taminated water, rainwater, drainage water and
washing water.
TMR pumps versions are intended for pumping
down to 2 mm 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 gar-
den 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 represents a health hazard.
CAUTION! Danger of property damage!
Pumping unpermitted substances can lead to prod-
uct damage.
The pumps are not suitable for water with coarse
contamination such as sand, fibres or combustible,
caustic fluids or for use in potentially explosive
areas.
Correct use of the product also includes following
these instructions.
Any use over and beyond these is interpreted as
incorrect use.
