• Pipe clamps are allowed to be tightened to a max. tight-
ening torque of 5 Nm.

1. Open the DN 50/70 combined connection with a suitable
saw. To do this, saw off the DN 50 connecting piece above
the lip.
2. Deburr and smooth the opening.
3. Push the collar (DN 50) over the connection piece and
secure it with a pipe clamp. Max. tightening torque: 5 Nm
4. Push another pipe clamp over the collar, insert the inlet
into the collar and connect both parts firmly with the pipe
clamp. Max. tightening torque: 5 Nm
5.3.3. Installation of the diaphragm hand pump for manual
draining of the collection reservoir
If the lifting unit fails, it can collect and hold the sewage inflow for
a period of time depending on the inlet. To avoid major dam-
age and/or bursting of the collection reservoir or the inlets, the
collected sewage can be pumped manually into the pressure pipe
using a diaphragm hand pump.
For this purpose, the diaphragm hand pump can be permanently
connected to the lifting unit.
NOTE
We recommend always having a permanent instal-
lation of the diaphragm hand pump on the lifting
unit so that sewage disposal can be guaranteed even
during a malfunction.
Note the following:
• The diaphragm hand pump must be installed at a corre-
sponding height for optimum operation.
• All connections must be absolutely leak-tight.
• For safe and reliable function, also refer to the installation
and operating instructions of the diaphragm hand pump.

The connection to the lifting unit is made at one of the two DN 50
inlets on the front or rear ends. The connection to the pressure
pipe is above the gate valve.
NOTE
The pressure-side connection of the diaphragm hand
pump can also be made directly into the collecting
pipe via its own backflow loop!

Electrical connection

POTENTIALLY fatal danger due to electrical volt-
age!
Incorrect electrical connections can cause fatal
electric shocks. Electrical connections may only
be carried out by a qualified electrician approved
by the local energy supply company, in accordance
with locally applicable regulations.
• The mains connection current and voltage must be as
stated on the rating plate.
• Earth the lifting unit according to the regulations.
The cross section of the cable for the protective ground
conductor connection must correspond to the local regu-
lations.
• A residual-current-operated protection switch (RCD) must
be installed in accordance with the local regulations!
• The electrical connections must be installed so they are
overflow-proof!
• The fitted switchgear and the optional alarm switchgear
for the collective fault signal must be attached in an over-
flow-proof manner.
• The power supply on the mains side must have a clockwise
rotating field.
5.4.1. Mains side fuse protection
The back-up fuse required must be rated according to the starting
current. Refer to the rating plate for the starting current.
Only slow-blow fuses or K-type circuit breakers are allowed to be
used as the back-up fuse. The max. fuse protection on the mains
side is:
• Liftson lix L1: 16 A
• Liftson lix L2: 25 A

5.4.2. Mains connection

The power supply cable is connected at the main switch on the
switchgear. The customer must provide the mains-side power
supply cables.
Also observe the installation and operating instruc-
tions for the fitted switchgear.
5.4.3. Adjusting the motor protection
The electronic motor protection in the switchgear monitors the
motor's maximum rated current. This is a factory setting and it
should be checked again. To do this, check the positions of the
individual DIP switches.
Read the installation and operating instructions for
the fitted switchgear.
5.4.4. Connecting an external alarm signal
The switchgear is fitted with a buzzer in the factory. In addition,
an external alarm signal can be connected via a potential-free
contact (SSM) in the switchgear (e.g. alarm switchgear, horn, flash
light).
The switching level for the alarm signal is approx. 200 mm for the
single-pump system and approx. 250 mm for the double-pump
system (via the installation surface upper edge)
