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 module is very heavy when filled, it must be placed on a suitable base (at least on slabs,
but preferably on a poured concrete base) to prevent it from subsiding.
► Horizontally align the base slab.
– The filter system must be positioned horizontally (max. deviation d ± 5 mm).
– Tip: Use commercially available concrete slabs, each measuring 500 × 500 mm. Five slabs are
required (one base slab for each corner and 1 for the centre). For the gravity fed system, an
additional slab for the Individual Module is required.
► 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.
► 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.
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.

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 690 mm below the max. water level. Tolerances
of up to -20 mm are permitted.
► Keeping the water level constant: A constant water level in the pond is necessary for operating the
gravity fed system. Tolerances of up to -20 mm from the max. water level are permitted.
– If the max. water level in the pond is exceeded, water flows out of the Drum Filter Module via the
dirt channel until the max. water level is reached again.
– If the water level goes below the max. water level by more than 20 mm, it is not possible to achieve
optimum or fault-free operation.
► Install the OASE ProfiClear Guard refill system. The ProfiClear Guard refill system automatically
supplies water to the pond if the water level goes below the specified water level.
