INSTALLATION
3. Mount the inlet pipe on the flange of the supply
box/distributor.
Max. tightening torque: 45 Nm
Connecting the ventilation line
A 2 m venting hose with Kamlock coupling is in-
cluded in the scope of delivery for connecting the
ventilation line. This venting hose must be used
so that the cover of the supply box/distributor
can be dismantled if necessary.
Comply with the following points when connect-
ing the ventilation line:
• Connection of a ventilation line is a specified
requirement and essential for correct function of
the lifting unit.
• The ventilation line must be routed via roof and
must be provided with gauze and a rain cap 60 cm
above the ground surface level.
• The ventilation line must be self-supporting.
• The ventilation line must be connected so it is
free from vibration.
• The connection as well as all unions must be
absolutely leak-tight.

pling)
1. Attach the venting hose to the hose clip (Kamlock
coupling).
2. Open the wings of the hose clip upward and insert
the locking pin.
3. Route the venting hose to the stationary venting
pipe.
4. Attach 2 hose clips on the venting hose.
5. Push the venting hose onto the ventilation pipe
and fasten with the two hose clips.
Max. tightening torque: 4 Nm
Defining the working area of the system
The motor housing of the sewage pump can reach
temperatures of up to 100°C during operation.
A corresponding working area must be defined
by the end-user. No personnel are permitted in
this safety zone during operation and no readily
flammable and combustible objects may be
stored there.
The working area must be marked in a way that
is unambiguous and clearly recognisable!
BEWARE of burns!
The motor housing can reach temperatures
of up to 100°C during operation. There is a
risk of burns! If personnel are present in the
working area during operations, then a guard
must be installed.

5.4. Electrical connection

POTENTIALLY fatal danger due to electrical
voltage!
Incorrect electrical connections can cause fa-
tal 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 regula-
tions.
• 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
earth conductor connection must comply with
local regulations.
• A residual-current device (RCD) must be installed
in accordance with the local regulations!
• The electrical connections must be installed so
they are overflow-proof!
• The power supply on the mains side must have a
clockwise rotating field.
5.4.1. Fuse on mains side
The back-up fuse must be rated according to the
starting current. You will find the starting current
on the rating plate.
Only slow-blow fuses or K-type circuit breakers
may be used as a back-up fuse.
5.4.2. Mains connection
The mains connection must be set up on a cor-
responding switchgear for controlling the lifting
unit.
Observe the installation and operating instruc-
tions for the respective switchgear!
5.4.3. Connecting the sewage pumps
The attached sewage pumps must be connected
to the switchgear in accordance with the wiring
diagram.
The power supply cable of the sewage pump
should be positioned in such a way that the
pump can be dismantled at any time from the
lifting unit and set down nearby without the
power supply cable needing to be disconnected
from the switchgear!
