Assembly Of The Pump Chamber - Kessel Aqualift F Installation Manual

The delivered shipment should include the following (see
section 2.2):
- KESSEL Inspection Chamber delivered in sections (for as-
sembly on-site)
- Sewage pump(s)
- Electrical Control Unit
The electrical control unit should be stored in a dry, frost
Important:
free area until time of connection. The cable ends of the
float switches must not come in contact with water or moi-
sture during storage or installation.
CAUTION:
- Caution- Heavy weight
The base of the inspection chamber as well as the pumps
and chamber cover each way over 30 kg! Be sure that ap-
propriate personnel and equipment (e.g. safety shoes, back
support, etc.) are used when moving or handling these
heavy parts. The pumps should be placed into the chamber
after the chamber is installed and lowered into the chamber
only with an appropriate winch / pully assembly.
- Caution - Danger of slipping
While entering or working in or around a chamber the dan-
ger of slipping is always present. Due to this it is mandatory
that a second worker always remains outside of the cham-
ber to aide / observe the other.
- Caution – Danger of tipping
Before the trench / hole is backfilled with soil, the possibili-
ty that the chamber tips or falls is always present. Due to
this, entry into the chamber should only take place after the
hole, in which the chamber is installed, is backfilled.
4.1 Installation
The base / bottom of the excavation in which the Aqualift F
is to be installed should be prepared with 30 cm even layer
of compacted gravel. On top of this layer of gravel should be
a 10 cm thick evenly compacted layer of fine stones. Now
place the bottom section of the pumping chamber into the ex-
cavation making sure that inlets / outlet, ventilation and pipe
cable outlets are in the correct location (see Section 4.2)
The excavation is then to be backfilled in 30 cm layers with
gravel (gravel to be group G1 according to ATV-A127). Each
of these 30 cm layers is to be compacted with a light duty
compactor. Make sure to connect any necessary inlets / ou-
tlet or other pipes before these areas are backfilled (see the
section 'connection of pipes'.

 The installation of the chamber needs to take into con-
sideration the appropriate load class. Installations in
pedestrian areas (Load Class A – 1.5 tons) and stan-
dard traffic areas (Load Class B - 12.5 metric tons) re-
quire that the upper section is firmly compacted into the
surrounding backfill (see illustration)
 For installation on fully access roadways (Class D –
40.0 ton), a concrete load distribution plate is required
on the surface (height of plate 150mm, 2x2 meters)
which should be poured around the upper section of
the chamber. This plate needs to be steel reinforced –
a plan for this is available upon reques).
 For installation in areas with high groundwater, the
chamber needs to be secured against floatation. In ad-
dition to this a re-enforced, groundwater resistant
chamber base is available at an additional cost.
 All inlet and outlet connections to the chamber must be
checked to assure they are secure and watertight.
