Installation - Kessel Aqualift F Anleitung Für Einbau, Bedienung Und Wartung

The delivered shipment should include the following (see
section 2.2):
- KESSEL Inspection Chamber delivered in sections
(for assembly 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- 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 manda-
tory that a second worker always remains outside of the
chamber to aide / observe the other.
- Caution – Danger of tipping
Before the trench / hole is backfilled with soil, the possibi-
lity 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 consi-
deration the appropriate load class. Installations in pede-
strian areas (Load Class A – 1.5 tons) and standard traf-
fic areas (Load Class B - 12.5 metric tons) require that the
upper section is firmly compacted into the surrounding
backfill (see illustration)
For installation on full access roadways (Class D – 40.0
ton), a concrete load distribution plate is required on the
surface (thickness of plate 150mm, 2x2 meters in size)
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 request).
For installation in areas with high groundwater, the cham-
ber needs to be secured against floatation. In addition 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.
