Connecting the inlet

The inlet can be located in the areas indicated on the rear wall, both side walls and the tank roof, as desired.

Follow these points to connect the inlet:

  • Only connect the inlet in the areas shown. Installing the inlet outside these areas can cause:
    • Leaking connections
    • Backflow into the inlet pipe
    • Impaired function of the lifting unit
  • To prevent surging inflow or air intake into the collection tank, install the inlet correctly.
  • CAUTION! Surging inflow or air intake into the collection tank can lead to malfunctions of the lifting unit.
  • To permit the inlet pipe to drain off by itself, install the inlet pipe with a slope gradient to the lifting unit.
  • Be conscious of the minimum inlet height (from floor to the centre of the inlet pipe): 180 mm (7 in).
  • Make sure that all connections are fully tight.
  • Install a shut-off valve in the inlet pipe.

  1. Lifting unit is installed correctly.
  2. Inlet pipe is installed to the collection tank. The consulting documents are obeyed.
  3. Installation material are prepared:
    1x hole saw 124 mm (5 in)
    1x seal DN/OD  110
    1x pipe clamp
  1. Mark the inlet on the collection tank.
  2. Cut the hole with the hole saw into the tank wall.
    To drill the hole, follow these points:
    - - Obey the dimensions of the inlet area. CAUTION! The drilled hole must be fully in the identified inlet area.
    - Max. speed of the drill: 200 rpm.
    - Examine the hole diameter. NOTICE! Drill the hole carefully. Impermeability of the connection depends on the drilled hole.
    - Make sure that the drilling chips fall cleanly from the hole saw. If the drilling chips attach to the hole saw, the material heats up too quickly and melts. If the material melts, obey these instructions:
  3. Stop drilling, let the material cool down, and clean the hole saw.
  4. Decrease the drilling speed.
  5. Adjust feed rate during drilling.
  6. Deburr the cut edge and make it smooth.
  7. Put the seal into the hole.
  8. Push the pipe clamp on the seal.
  9. Coat the inner surface of the seal with lubricant.
  10. Push the inlet pipe into the seal.
    Push the inlet pipe 10 … 20 mm (0.4 … 0.8 in) into the collection tank.
  11. Obey the value specification, or else the function of the lifting unit can be impaired.
  12. Fasten the seal and the pipe with the pipe clamp. Tightening torque: 5 Nm (3.7 ft·lb).
  1. Inlet is connected. Next step: Connecting the ventilation pipe.
