Installation in the ground
The ACO Clara waste water treatment plant is designed as a self-suppor-
ting plastic tank for installation in a ground bed without any concrete
encasement.
The procedure for embedding the plant in the
ground described below is intended for the
installation of the inlet pipe to a depth of 0.8 m
and must not be used for impervious soil or if the
level of underground water is above the level of the base
plate or if the plant is situated on a slope steeper than 10%.
Installation procedure:
1. Excavation of foundation pit – the subsoil must not be loosened by
extraction. If necessary it will be compacted so as to correspond with
compact natural material.
2. Concreting of base plate – the tank will be laid on a concrete reinfor-
ced plate thickness min. 150 mm with a flatness of ± 5 mm/m. No
irregularities must occur between the tank bottom and the plate.
3. Placing plant into foundation pit – The pit must be excavated in such a
way that after the concreting of the base plate and emplacing the
plant the upper edge of the cover will be approx. 70 mm above
ground level.
4. Connect the: inlet pipe
outlet pipe
hose from the blower
ventilation line (if needed)
5. Filling with water – gradually fill the entire interior of the plant with
water up to 1 m.
6. Backfill – the backfill must be done in single layers with a maximum
thickness of 400 mm thick all round the plant perimeter together with
compaction. The compaction grade is calculated to be between
90–92% Pgs.
7. Gradual filling of tank with water – gradually fill the tank with water
and backfill the surroundings of the plant. A water level ca. 300 mm
above the backfill level must be permanently kept in all parts of the
tank.
8. Gradual backfill – proceed with tank backfill acc. to item 6.
9. As soon as the water level in the waste water treatment plant reaches
the level of the outlet pipe, the remaining backfill is done without addi-
tional filling up with water.
10. Proceed with backfill up to ground level.

5.5.1 1 phase motor
The plant connection arrangement consists of the connection of the blo-
wer to a socket with an earth pin powered from 1/N/PE AC 230V/50Hz
mains installed as per national safety standards and regulations on blo-
wer space. The recommended socket protection is via a 10A char.B cir-
cuit breaker. A revision will be made to the socket according to the
appropriate national standards and regulations.
5.5.2 3 phase motor
The plant connection arrangement consists of the connection of the blo-
wer to a switchbox powered from 3/N/PE AC 230V/50Hz mains installed
as per national safety standards and regulations on blower space. The
recommended protection of the blower is via motor-circuit breaker which
is sized according to rating plate value. A revision will be made to the
cable according to the appropriate national standards and regulations.
While using of blower with 3 phases engine to
check proper engine rotation (rotation arrow is
on the body of blower).
