Installation and Operating Instructions ABS lifting station Nirolift & SanisettABS lifting station Nirolift & Sanisett4.3 Opening of the collection tank inlet portsOnly open inlet ports that are to be used. Only saw off as little as possible so that as much neck as possible isleft for the plug connection. (Note the notch on the port neck).File down sharp edge inside and outside.4.4 Discharge lineThe discharge line must be installed in compliance with the relevant regulations.DIN 1986/100 and EN 12056 applies in particular to the following:The discharge line should be fitted with a backwash loop (180° bend) located above the backwash level andshould then flow by gravity into the collection line or sewer.The discharge line should not be connected to a down pipe.No other inflows or discharge lines should be connected to this discharge line.ATTENTION The discharge line should be installed so that it is not affected by frost.The vent line is connected by means of a push-on sleeve to the vertical outlet at the top of the collection tank.It should be of constant cross-section (min. DN 70) and should have a continuous rise to above roof level.4.5 Mounting of the upper fittingInsert the white plastic installation cover into the frame of the upper fitting. The cover is only suitable forfoot traffic (See Figure 5).Adjust the upper fitting in the tank opening until the edge of the rim is level with the finished floor. The rimshould also be parallel with the wall or floor tiles.When installation is complete remove the installation cover and insert the cover with siphon into the frame.This cover is only suitable for foot traffic.Height adjustments up to 130 mm is possible by pushing in or pushing out the upper fitting. It is possible toincrease the depth at which the collection tank is installed by the use of one sump extension piece. Theseextend the sump by 150 mm.ATTENTION A maximum of 1 sump extension piece may be fitted.4.6 Location of power supply cable and float switchThe connection cable for the pump is fed through the cable pipe and brought into the room where the powersupply is located by means of a branch pipe (T-piece). The connection cable is fed through the slot in the cableinlet and the cable inlet itself is pushed firmly into the branch pipe.NOTE In the case of twin units the connection cables for the float switches should be laid ina similar manner to the pump power cable.Branch pipe (T-piece)Cable inletVent lineMotor connection cable1.2.3.4.1067-00Figure 7 Cable inlet---1.2.3.
