– 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.
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.
4.1.1 Pump fed system

A, C
System specific requirements
► Horizontally align the base slab.
► 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.
4.1.2 Gravity fed system

B, D
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 690 mm … 710 mm below the max. water level.
► 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.
4.2 Connecting the drum filter
4.2.1 Information regarding pipes
► Use suitable pipes.
► Do not use any right-angled bends. Bends with a maximum angle of 45° are very efficient.
► Glue plastic pipes to ensure a permanent and reliable joint or use socket joints with clips to stop them
from coming apart.
► Standing water in pipes can freeze when there is a hard frost and cause pipes to burst. For this reason,
lay the pipes and hoses with a gradient (50 mm/m) to ensure that they can run empty.
► For gravity fed systems, it must be possible to shut off the supply from the pond and the return to the
pond for maintenance and repair work. For this reason, install suitable slide valves.
► In the case of the gravity fed system, the sum of the losses in the supply line must not exceed 7 mbar
(7 cm).
– Otherwise the water level in the filter system will go below the minimum water level during
operation. Optimum, fault-free operation will no longer be possible.
