English INSTALLATION
DANGER due to electrical voltage!
Defective electrical components (e.g. power
supply cables, switchgear, plugs) represent
a risk of fatal injury due to electric shock!
Defective components must immediately be
renewed by a qualified electrician.
BEWARE of moisture!
Ingress of moisture into the electrical compo-
nents (cables, plugs, switchgear) will result in
damage to these components and the lifting
unit. Never immerse the electrical compo-
nents in a liquid, and protect them against the
ingress of moisture.
• The lifting unit must be protected from direct
sunlight and frost. This can lead to significant
damage to the collection reservoir or the electri-
cal components!
• Following lengthy storage, the maintenance work
according to EN 12056-4 must be carried out
prior to commissioning.
If you comply with these rules, your lifting unit
can be stored over a lengthy period. However,
note that the elastomer components are subject
to natural embrittlement. If the product is to be
stored for longer than 6 months, we recommend
checking these parts and replacing them as nec-
essary. Consult the manufacturer for details.
4.4. Return delivery
Lifting units that are sent back to the factory
must be cleaned to remove impurities and, if they
have been used with fluids that are harmful to
health, they must also be decontaminated.
For shipping, the parts must be packed in tear-
proof plastic bags of sufficient size in such a
manner that they are tightly sealed and leak-
proof. Furthermore, the packaging must protect
the lifting unit from damage during transporta-
tion. If you have any questions, please contact
the manufacturer!
5. Installation
In order to prevent damage to the product or seri-
ous injury during installation, the following points
must be observed:
• Installation work – assembly and installation
of the lifting unit – may only be carried out by
qualified persons. The safety instructions must be
followed at all times.
• The lifting unit must be inspected for transport
damage before any installation work is carried
out.
5.1. General
For planning and operation of technical sewage
systems, observe the pertinent local regulations
and directives for sewage technology (such as
those of the German Association for Water,
Wastewater and Waste).
In particular, pressure surges which occur, e.g.
when closing the non-return valve, may be sever-
al times higher than the pump pressure, depend-
ing on the operating conditions. These pressure
surges can cause irreparable damage to the unit.
Therefore, pay attention to the pressure resist-
ance and the longitudinal force fit connection
of the pipe.
Furthermore, the existing piping must be checked
to ensure it is correctly connected to the unit. The
existing pipe system must be self-supporting and
is not allowed to be supported by the lifting unit.
In particular, the following applicable regulations
must be complied with for installation of lifting
units:
• DIN 1986-100
• EN 12050-1 and EN 12056 (gravity drainage
stations within buildings)
Comply with the locally applicable regulations
in your country accordingly (e.g. national build -
ing regulations)!
5.2. Installation methods
• Stationary dry well installation in buildings and
sumps
5.3. Installation
DANGER due to overpressure
Exceeding the application limits can result in
excessive pressure in the collection reser-
voir. This can cause the collection reservoir
to burst! There is a health risk due to contact
with sewage polluted by bacteria (faeces).
Ensure that the inlet is blocked if the unit
malfunctions.
The following application limits must be ob-
served strictly:
• Max. intake/h: 1050 l (FIT L1) or 3000 l (FIT L2)
• Max. suction head: 5 m
• Max. admissible pressure in the pressure pipe:
3 bar
DANGER due to explosive atmosphere!
An explosive atmosphere can form within the
collection reservoir. If the collection reservoir
is opened (e.g. maintenance, repair, defect),
this atmosphere could spread within the
operating space. There is a risk of fatal injury
due to explosion! The operator is responsible
for defining a corresponding explosion zone.
Observe the following:
• The lifting unit, mounted switchgear and plug
are not Ex-rated!
• Take appropriate countermeasures to avoid an
explosive atmosphere in the operating space!
The following information must be observed
when installing the lifting unit:
• The work must be carried out by specialist per -
sonnel, and electrical work must be performed by
an electrician.
