Installation and operating instructions Wilo-EMUport CORE 41
•
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 types
• Stationary dry well installation in buildings
• Stationary subsurface installation in pump cham-
bers present on-site
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 system
malfunctions.
The following application limits must be ob-
served strictly:
• Max. inlet:
- CORE 20.2: 20 m³/h
- CORE 45.2: 45 m³/h
- CORE 50.2: 50 m³/h
- CORE 60.2: 60 m³/h
•
Max. reservoir flooding:
- CORE 20.2: 5 m for max. 3 h
- CORE 45.2, 50.2, 60.2: 6,7 m for max. 3 h
• Max. permitted pressure in the system pres-
sure pipe: 6 bar
•
Max. fluid temperature: 40 °C
DANGER – 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 end-user 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:
•
This work must be performed by qualified per
-
sonnel and electrical work must be performed by
a qualified electrician.
• The operating space must be clean, dry, well-lit
and free of frost, and furthermore equipped for
the respective lifting unit.
• The operating space must be easily accessible.
Make sure that there are adequate access oppor-
tunities for the transport equipment including the
lifting unit, and that any elevators required are
sufficiently large and have an adequate bearing
capacity.
• Adequate ventilation (eight-fold air replacement)
of the operating space must be ensured.
• It is necessary to guarantee that lifting equip-
ment can be installed without difficulty, since
this will be required for installing/dismantling the
lifting unit. The lifting equipment must be able to
reach the place where the lifting unit is used and
placed without danger. The set-down location
must have a solid bearing surface. Transport
straps must be used as load-bearing equipment
for transporting the lifting unit. These must be
fastened to the designated attachment points
on the reservoir. Lifting gear must be technically
approved.
• The lifting unit must be easily accessible for oper-
ation and maintenance. A space of at least 60 cm
must be left clear around the unit (WxHxD).
• The installation surface must be solid (suitable for
accommodating dowels), horizontal and flat.
• The placement of any existing or still-to-be
installed piping (for inlet, pressure and venting) is
to be checked with regard to connection options
to the unit.
• A pump sump must be arranged within the op-
erating space for draining it. This must have the
minimum dimensions of 500x500x500 mm. The
pump used must be selected according to the
delivery head of the lifting unit. In an emergen-
cy, it must be possible to drain the pump sump
manually.
• Power supply cables must be laid out in such a
way that safe operation and trouble-free instal-
lation/dismantling are possible at all times. Never
carry or pull the lifting unit by the power supply
cable. Check whether the cable present is long
enough for its cross-section and its installation
type.
• Structural components and foundations must be
of sufficient stability in order to allow the product
to be fixed securely and functionally. The operator
or the supplier is responsible for provision of
the foundations and their suitability in terms of
dimensions, stability and strength!
• Check that the available design documentation
(installation plans, layout of the operating space,
intake ratios) is complete and correct.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.
• Also refer to all regulations, rules and laws for
working with heavy and suspended loads. Wear
appropriate protective clothing/equipment.
5.3.1.
Basic advice on the fixation of the lifting unit
Lifting units must be installed so they are pre-
vented from twisting and also in an anti-buoyant
fashion, depending on the installation location.
For this purpose, the lifting unit must be anchored
to the floor of the operating space. The lifting
unit can be installed on various constructions
(concrete, steel, etc.). Observe the following
instructions for the fixation material:
