3 Transport and interim storage
Immediately check the product for damage in
transit on arrival. If damage is found, the necessary
procedure involving the forwarding agent must be
taken within the specified period.
CAUTION! Risk of damage!
Incorrect transport and incorrect storage can
damage the pump.
• When transporting, only carry or suspend the
pump by the shackle – never by the cable!
• When the pump is lowered into deep sumps or
pits, a rope or chain must be used.
• The pump must be protected from moisture,
frost and mechanical damage during transport
and interim storage.
4 Intended use
The macerator pumps enable the installation of
pressure pipes with small cross-sections starting
from DN 40! Submersible pumps from the MTC 40
series are suitable for pumping sewage with the
usual admixtures (as stipulated in DIN 1986, Part 3
from sumps, pits and pumping stations that are
not linked to the public sewer network. They may
be used for pumping sewage from lavatory and
urinal systems only if no Ex protection is required.
The submersible pump is frost-resistant up to
-20 °C when stored in a dry place. However, it
must not be allowed to freeze in water when
installed.
The noise emission of the immersed pump is less
than 70 dB(A).
DANGER! Risk of fatal electrical shock!
The pump must not be used for draining swim-
ming pools, garden ponds or similar installations
if there is someone in the water.
WARNING! Health hazard!
Owing to the materials used, the pumps are not
suitable for pumping potable water! Unpurified
wastewater is a health hazard.
CAUTION! Risk of damage!
Non-permitted substances in the fluid can
destroy the pump. Abrasive solids (e.g. sand)
increase pump wear.
Pumps without an Ex rating are not suitable for
use in potentially explosive areas.
Using the product as intended also means follow-
ing these instructions.
Any other use is considered improper use.
5 Product information
5.1 Type key
5.3 Pump with float switch
(MTC40 F 16.15/7/1-230-50-2):
MTC40 F...1-230 (1~) pumps work automatically.
This is achieved by a float switch that switches on
the pump via the free cable length once the water
reaches a certain level, and turns it off again when
the water reaches a minimum level.
5.4 Pump without float switch
(MTC40 F 16.15/7/3-400-50-2):
MTC40 F...3-400 (3~) pumps without a float
switch are switched via an external On/Off
switching device such as a switchgear
(accessories).
