N O T E
The filter system operates day and night and causes rinsing noises during the automatic cleaning
cycles. (→ Technical data)
► Please protect the general public and your neighbourhood from noise disturbance and comply with
the statutory noise regulations.
► Enclose the filter system such that the enclosure effectively absorbs the noises.
► Select the location of the filter system in order to avoid noise disturbance.
Plan the installation of the filter system. With careful planning, taking the ambient conditions into account,
you will obtain optimum operating results.
The following conditions must be met:
► As the filter modules are very heavy when filled, they must be placed on a suitable base (at least on
slabs, but preferably on a poured concrete base) to prevent them from subsiding.
► Plan sufficient space for carrying out cleaning and maintenance work.
► Drain the dirty water into the drain or far enough away from the pond so that it cannot flow back into
the pond.
– If the coarse soiling and dirty water both run into the same pipe, it is important to use at least DN
110 pipes.
N O T E
A water course or waterfall guarantees optimum water return to the pond. In this way, the filtered pond
water is enriched with oxygen before it is returned to the pond.
5.1.1
Pump fed system
A, F
System specific requirements
► Horizontally align the base slab.
► Install the Drum Filter Module 150 mm higher than the subsequent Moving Bed Module so that the
connections of the two modules (outlet and inlet) are at the same height.
– Tip: Use three commercially available concrete slabs, each measuring 500 × 500 × 50 mm.
► Position the outlet of the filter system such that the water level in the Drum Filter Module is 230 ... 350
mm below the edge of the container.
– Otherwise, optimum or fault-free operation will not possible.
► Position the inlet in the pond (e.g. via a water course or waterfall) so that it is lower than the outlet of
the filter system.
5.1.2
Gravity fed system
B, G
System specific requirements
The correct installation and constant water level in the pond are important prerequisites for ensuring
optimum and fault-free operation of the gravity fed system.
Making a filter pit:
► Excavate a pit of sufficient dimensions to accommodate the filter system.
► Horizontally align the base slab.
► Secure the walls of the pit from falling in (with masonry or concrete).
► Ensure that the pit is protected from flooding. Provide a rain water drain.
Installing the filter system:
► Determine the max. water level of the pond.
► The base slab supporting the filter system must be 700 mm below the max. water level (max.
tolerance: -20 mm).
► Keeping the water level constant:
