• of a stand-alone toilet at a height of 180 mm
• and a wall-mounted toilet at a height of 250 mm.
Fig. 4.: Overview of inlets
1 Free inlet surfaces
The following information must be observed when connecting the
inlet pipe:
• The inlet is only allowed to be within the marked areas.
If the inlet is outside the marked areas
• the unit could leak.
• there could be backflow into the connected inlet pipes.
• The inlet must be routed so it is self-draining. Further-
more, an inlet surge must be prevented, as must any air
intake.
An inlet surge and/or air intake can cause malfunc-
tions of the lifting unit!
• The min. connection height is 180 mm.
An inlet at less than this height can lead to backflow
in the inlet pipe!
• The connection as well as all unions must be absolutely
leak-tight. To do this, the inlet must be horizontal (±5 °) to
the collection reservoir.
• A gate valve must be installed in the inlet before the
reservoir!
• Pipe clamps are allowed to be tightened to a max. tight-
ening torque of 5 Nm.

1 Reservoir wall
2 Keyhole saw
3 Inlet seal
1. Route the inlet to the reservoir and mark the inlet connec-
tion on the reservoir.
2. Use the supplied keyhole saw to cut the hole for the DN
100 inlet into the reservoir wall.
For a DN 150 inlet, the DN 150 intake set (available
as an accessory) must be present.
The following points must be observed when doing this:
• Comply with the dimensions of the inlet surfaces
• Maximum rotation speed of the drill: 200 rpm
• Make sure the excess material in the drill bit is removed
completely:
• If the excess material removal is reduced, the material
will heat up excessively and melt.
Interrupt the drilling process, allow the material to
cool and clean the keyhole saw!
• Reduce the speed of the drill.
• Vary the feed pressure when drilling.
• Check the hole diameter: DN 100 = 124 mm;
DN 150 = 175 mm
4 Inlet pipe
5 Pipe clamp
NOTE
Drill the connection for the inlet carefully. The sub-
sequent impermeability of the connection depends
on this!
3. Deburr and smooth the cut surface.
4. Insert the inlet seal into the hole
5. Moisten the inner surface of the inlet seal with lubricant
6. Push the pipe clamp onto the inlet seal.
7. Push the inlet pipe into the inlet seal. The inlet pipe must
be pushed into the reservoir by 10...20 mm.
8. Connect the inlet seal and pipe firmly to the pipe clamp.
Max. tightening torque: 5 Nm.
Connecting the ventilation line
There are two DN 50/DN 70 combined connections on the tank
roof for connecting the bleed line.
Comply with the following points when connecting the ventilation
pipe:
• Connection of a ventilation pipe is a specified requirement
and essential for correct function of the lifting unit.
• The ventilation pipe must be routed up to higher than roof
level.
• The ventilation pipe must be self-supporting.
• The ventilation pipe must be connected so it is free from
vibration.
• The connection as well as all unions must be absolutely
leak-tight.
• A max. tightening torque of 5 Nm is permitted when
using pipe clamps.

nection
1. Open the DN 50/70 combined connection with a suitable
saw. To do this, saw off the DN 70 connecting piece above
the lip.
2. Deburr and smooth the opening.
3. Slide the supplied collar (DN 70) onto the connecting piece
up to the inner collar and fasten with the pipe clamp.
4. Attach the ventilation pipe to the collar.
Connect inlet DN 50
As a general rule, it is recommended for all inlets to be routed to
the lifting unit centrally within an inlet pipe. As this is not always
possible, the Liftson lix L has an extra DN 50 connection on the
tank roof (a DN 50/DN 70 combined connection).
Note the following points when using the DN 50 connection:
• The inlet is only allowed to use the existing connecting
pieces.
• The inlet must be routed so it is self-draining. Further-
more, an inlet surge must be prevented, as must any air
intake.
An inlet surge and/or air intake can cause malfunc-
tions of the lifting unit!
• The connection as well as all unions must be absolutely
leak-tight.
