• Ensure the proper edge clearance in order to
prevent the construction material from tearing or
chipping.
• The depth of the borehole depends on the length
of the bolts. The borehole should be 5 mm deeper
than the bolt length.
• Drilling dust impairs holding strength. Therefore,
Always blow or vacuum out the borehole.
• Make sure the fixation material is not damaged
during installation.
5.3.2. Stationary dry well installation in buildings
Work steps
The lifting unit is installed in the following steps:
• Positioning the lifting unit and anchoring it to the
floor
• Connecting the pressure pipe
• Connecting the inlet
• Connecting the ventilation line
• Defining the working area
Positioning the lifting unit and anchoring it to
the floor
Fig. 2: Installing the lifting unit
1 Attachment points
2 Fastening straps
The lifting unit is anchored to the floor with four
fixations.
1. Place the lifting unit in the required position and
align it.
2. Mark out the boreholes.
3. Move the lifting unit to one side and drill the
boreholes according to the fixation material used.
4. Reposition the lifting unit and fasten it to the
fastening straps with the respective fixation
material.
Max. tightening torque: 30 Nm
Connecting the pressure pipe
BEWARE of pressure surges!
Pressure surges can exceed the maximum
permitted operating pressure many times
over. This can cause the pressure pipe to
burst! Attempt to avoid pressure surges by
the way that the pressure pipe is routed. The
piping and connection elements used must
have corresponding pressure resistance!
NOTE
• According to EN 12056-4, the flow rate at
the duty point must be between 0.7 m/s and
2.3 m/s.
• Reducing the pipe diameter in the pressure pipe
is not permitted.
The following information must be observed
when connecting the pressure pipe:
• The pressure pipe must be self-supporting.
• The pressure pipe must be connected so it is free
from vibration, noise-insulated and flexible.
42
• The connection as well as all unions must be
absolutely leak-tight.
• The routing of the pressure pipe must be frost-
proof.
• To avoid any backflow from the main public sew-
er, install the pressure pipe as a loop. The bottom
edge of the pipe loop must be above the locally
defined backflow level at its highest point.
• Gate valves and non-return valves are already
built-in. The discharge pipeline can be connected
directly.

1 Pressure connection with pipe connection
2 Pressure connection with flange connection
1. The pressure pipe must be routed so that the
connection is perpendicular to the pressure
connection. Please refer to the system documen-
tation or the catalogue for the precise dimensions
of the lifting unit.
2. Connecting the pressure pipe to the pressure
connection:
• Pipe connection
Connect the pressure connection and the
discharge pipe to a welded bushing. Weld the
connection so it is leak-tight by heating the
bushing.
• Flange connection
Use a flange connector for flexible and acous-
tically insulated mounting of the discharge
pipeline to the pressure connection. Place a
gasket between flange connector and pressure
connection.
Max. tightening torque: 50 Nm
Connecting the inlet
The following information must be observed
when connecting the inlet pipe:
• The connection is made at the supply box/dis-
tributor.
• The inlet must be routed so it is self-draining.
Furthermore, an inlet surge must be prevented, as
must any air intake.
An inlet surge and/or air intake can cause mal-
functions of the lifting unit!
• The connection as well as all unions must be
absolutely leak-tight.
• The structure of the inlet must happen with a fall
to the supply box/distributor.
• A gate valve must be installed in the inlet up-
stream of the supply box/distributor!

2 Inlet connection
1. Route the inlet up to the supply box/distributor.
2. Place a gasket between supply box/distributor
and inlet pipe flange.
