The KESSEL-Ecolift
, designated as a
2.1 Application
®
DIN EN 13564 Type 3 backwater valve, is
designed to be installed in wastewater
drainage pipes with or without raw sewa-
ge (WC connection). The installed sy-
stem offers reliable wastewater drainage
even during times of backwater. The
pump operates only during backwater
and pumps the building's wastewater
through a pressure pipe and into the pu-
blic sewer (pressure pipe should be run
above the backwater level (ground level)
and then into the public sewer)). During
normal non-backwater conditions, the
wastewater simply flows through the Eco-
lift and drains into the public sewer with
the force of gravity. The Ecolift ist no a rat
or rodent protection device! In the case of
rat or rodent danger in the drainage piping
system, the Ecolift should be properly
protected against rat or rodent damage.
Requirements for proper operations are:
Important:
➡ Drainage pipe must be properly slo-
ped (note- the Ecolift itself has an ele-
vation drop between its inlet and out-
let of 9mm)
➡ A higher proportion of waste in the
wastewater which will allow self clea-
ning and proper operation.
➡ Proper installation, especially proper
ventilation of the inlet drainage pipe
according to DIN EN 12056 / DIN
1986-100
➡ Wastewater flowing through the Eco-
lift which contains elevated level or
oils or grease will require that mainte-
nance and cleaning increments of the
Ecolift are increase.
➡ Rainwater surface area which is
connected to the Ecolift must not ex-
ceed 20 square meters.

2. General
The KESSEL Ecolift consists of a base
housing with pump and backwater valve
and an electrical package. The electrical
package consist of:
1. Two optical probes and the backwater
flap motor
2. A control unit with digital display (230 V,
50 Hz, Protection Class IP 54) with
back up battery feature (twin 9-volt bat-
teries) for alarm warnings during power
outages
3. Installation an Operation Manual
During the building's construction phase,
2.3 Pre-installation tips
only the Ecolift housing is installed and
connected. Also during this time the out-
let pressure pipe is to be connected. Nor-
mally during this time the building is not
equipped with electrical power meaning
that electrical connections (Section 4)
and commission (Section 5) will occur at
a later time. The electrical package and
the control unit should be properly stored
in a clean and dry location. The protective
caps should only be removed immediate-
ly prior to use.
Attention:
The pump is shipped with a transportati-
on safety band which needs to be remo-
ved before being placed into operation.
2.4 General information for the installa-
tion of backwater valves
According to DIN EN 12056 it is not allowed
to connect all drainage fixtures from a buil-
ding (including those located above the
backwater level – ground level) through a
backwater valve. The reason being that
when the backwater flap is in the closed po-
sition due to backwater / flooding no waste-
water will be able to flow through the back-
water valve meaning that the building's own

wastewater will flood out of the lowest drai-
nage fixture connected (normally in the ba-
sement) to the backwater valve.
Only drainage fixtures located below the
backwater level (ground level) should be
protected from backwater via connection to
the Ecolift® . All drainage fixtures located
above the backwater level should not be
connected to the Ecolift and should be drai-
ned via a separate drainage pipe directly
into the public sewer.
If installed properly as discussed above, du-
ring backwater the backwater level will only
reach ground level height meaning they are
not a danger of flooding drainage fixtures lo-
cated above the backwater level. Drainage
fixtures below ground which are drained
through a separate pipe through the Ecolift
will be protected from backwater damage.
Rainwater drainage pipes should never be
connected to a backwater valve.
2.5 Pressure connection
The outlet pressure pipe should be in-
stalled according to DIN EN 12056. Pres-
sure connection: 1 ½ inch outer thread
(Article Number 28040) contains 5 meters
of pressure pipe with outer diameter
50mm and an adaptor with fastening
clamp. As an alternative, a D=40mm
pressure pipe min. 38mm can be used
with a PVC connection. The pressure
pipe should be laid above the locally de-
fined backwater level and then immedia-
tely connected to a ventilation drainage
pipe with a minimum size of DN 70. Non-
pressure pipes (such at HT drainage pi-
ping) are not allowed for use as the pres-
sure pipe outlet.
This pressure pipe will be firmly connec-
ted to the Ecolift by the installer but will
also allow this pipe to be removed later for
servicing if required.
