degree of foam formation
• Sewage from drainage objects which lie above the back-
flow level and can be drained by means of gravity (acc. to
EN 12056-1)
• Explosive fluids
• Potable water
The system must be installed in accordance with the general rules
as detailed in EN 12056 and DIN 1986-100.
The intended use includes complying with these instructions. Any
other use is considered to be outside the intended use.

3.1.1. Application limits

DANGER due to overpressure
Exceeding the application limits can result in
excessive pressure in the collection reservoir if the
unit malfunctions. This can cause the collection
reservoir to burst! There is a health risk due to con-
tact with sewage polluted by bacteria (faeces). Al-
ways comply with the application limits and ensure
that the inlet is blocked if the unit malfunctions.
The following application limits must be observed strictly:
• Max. intake/h:
• Single-pump system: 1050 l
• Double-pump system: 3000 l
The maximum inflow must always be less than the
volume flow of the pump at the respective duty
point.
• Max. suction head: 5 m
• Max. admissible pressure in the pressure pipe: 3 bar
• Max. fluid temperature: 40 °C, 60 °C for max. 3 min
• Max. ambient temperature: 40°C
• Operating mode: S3 10%, 120 s
The unit is not designed for permanent operation!
The max. volume flow applies to intermittent opera-
tion according to EN 60034-1!
• Also comply with further information in the "Technical
data" section!

Set-up

The Salmson-Liftson lix L is a submersible, fully automatic sewage
lifting unit that is ready for connection in single-pump and dou-
ble-pump versions.

3.2.1. Collection reservoir

Gas and water-tight collection reservoir made from PE plastic
with special container geometry for reliable operation without any
build-up of deposits.
The inlet connections (DN 100 and DN 150) can be selected as
required on both sides and on the rear end in the area marked. The
pressure connection DN 80 is configured vertically above the res-
ervoir. A non-return valve with ventilation devices integrated in
the pressure connection.
In addition, the lifting unit has two further DN 50/DN 70 com-
bined connections on the tank roof for intake and venting and two
DN 50 connections on the front end and two on the rear end for
emergency draining.
For simple maintenance of the unit, the collection reservoir is
equipped with an inspection opening.
Furthermore, the reservoir also has two fastening straps. This al-
lows the lifting unit to be anchored in an anti-buoyant way to the
ground with the supplied fixation material. The fastening straps
also function as transport carrying handles.
3.2.2. Pump unit
The fitted pump unit consists of the motor with the fitter impeller
and an adapter ring.
The motor is a watertight, encapsulated glanded motor with a
stainless steel housing and three-phase design. The cooling is
done by the ambient air. The waste heat is given off via the motor
housing. The motor is equipped with a thermal winding monitor
with bimetallic strips. The winding monitoring is displayed and
reset via the connected switchgear.
The adapter ring connects the complete unit with the collection
reservoir.

3.2.3. Level control

The level control is fitted in the collection reservoir. Rod float
switches are used as signal transmitters. The switching points are
set and specified.
3.2.4. Switchgear
The system is controlled via the fitted switchgear. The switchgear
can also be used to implement a collective fault signal (SSM). The
cable from the motor to the switchgear is 4 m long.
See the enclosed installation and operating instructions for the
precise switchgear specifications.
