the presence of atmospheric humidity or could ignite upon contact with oxygen,
the unit must also be neutralised and blown through with anhydrous inert gas
to ensure drying.
4. Always complete and enclose a certificate of decontamination when returning
the lifting unit. (ðSection12,Page67)
Always indicate any safety and decontamination measures taken.

Design The lifting unit consists of a stable collecting tank (1) with integrated submersible
motor pump (5), an inlet-side connection (2) and a discharge-side connection (4).
Function The fluid to be handled flows into the lifting unit through the inlet-side connection
(2) and is collected in an odour-tight and water-tight plastic tank (1). When a
specified fluid level is reached, the float switch (3) triggers the automatic start of the
submersible motor pump (5). The fluid handled is then pumped through the
discharge-side connection (4) to a level above the flood level and discharged into the
public sewer.

1. Excavate the construction pit. The construction pit must be dry during
construction.
2. Fill the level pit floor with a horizontal bedding layer of approximately 200mm
and compact the bedding.
3. Remove cover plate 68-3 with extension 13-21 from collecting tank 591.
4. Remove the parts located in the tank and keep them in a safe place.
5. Fit provisional cover 185 to protect the collecting tank.
6. Insert the collecting tank into the construction pit. Level it and backfill around
the base.
5.3.2 Connect the underfloor box piping
CAUTION
