1 Plastic flange (piping) with flat face
2 Spacer disc
3 Cast iron flange (lifting unit) with raised face
In case of cast iron flanges (with raised face) to be connected to plastic flanges (with
flat face), the raised face must be compensated by split spacer discs.

5 to 7 2
Two split spacer discs are included in the cardboard box supplied with each lifting
unit.
Inlet line
A gate valve must be fitted so that the inlet line can be shut off temporarily during
repair work or servicing. For lifting units directly connected to the toilet, the inlet
side gate valve is not required.
✓ Piping weights have been supported at the site.
✓ All inlet nozzles of the collecting tank are closed.
1.
Determine which connection nozzles will be used.
2. Open the nozzles required by sawing off the nozzle faces (▼A) (approx. 10 mm).
Fig. 10: Opening the nozzles
NOTE
On mini-Compacta UZS1.150 the inlet nozzle arranged at 180 mm cannot be used.
Vent line
Sewage lifting units to EN 12050-1 must be vented through the roof.
The vent line must not be connected to the inlet-side vent line of a grease separator.
Connect the DN 50 or DN 70 vent line to the vertical vent nozzle by means of the
flexible hose connection, making sure that the connection is smell-proof.
If changes of direction are unavoidable, the pipe should be laid with a minimum
gradient of 1:50.
Drainage nozzle for hand diaphragm pump
NOTE
We recommend connecting a hand diaphragm pump (available as accessory) to
allow complete drainage of the tank for servicing work.
Fit this pump, using the flexible hose connection supplied, after having opened the
DN 40 nozzle.
