Note:
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, B, F
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
C, D, E; 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 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.
