Operating modes
The ProfiClear Classic module filter can be configured and installed in many ways. In the following, two operating
modes are described: the "principle of gravity" and the "pumped system". Please contact a specialist for all other
operating modes and special requirements!
Principle of gravity (A)
The filter system (M 1/ M 2/ M 3/ M 4) is completely buried. Soiled pond water enters the first filter module (M 2/ M 3/ M
4) by gravity by passing the bottom drain. In the pump chamber (M 1) the pump is located at the end of the systems
and returns the cleaned water into the pond.
Advantages of the principle of gravity:
•
efficient removal of suspended matter because the dirt enters the coarse dirt separating module (M 2) without being
pumped
•
low energy requirement due to negligible height differences and low frictional loss
•
The filter system can be easily hidden
Pumped systems (B)
The filter system (M 2/ M 3/ M 4) can be placed above the pond water level. Soiled pond water is fed out of the pond
(or out of the levelled pump chamber M 1) and into the filter system using a pump. The cleaned water is returned to the
pond by gravity, passing a pipe.
Advantages of the pumped systems:
•
easily retrofittable to existing ponds
•
low installation requirement
•
the system can be easily extended
Module installation (planning aid)
Important! In swimming ponds, the filter pump must be positioned outside of the pond, and always below the
pond water level. Otherwise danger of running dry and, as a result, damage to the filter pump!
Principle of gravity (A)
Dig a pit of sufficient size to accommodate the filter system (M 1/ M 2/ M 3/ M 4). For the dimensions/execution,
take the following into account:
•
distance from the pond edge (A-1) which cannot be flooded and conforms with the regulations. It is not permitted to
install units operated with a rated voltage of 230 V in swimming ponds. Observe a minimum distance between units
and pond (e.g. in Germany 2 m, in Switzerland 2.5 m etc.)
•
that the inlet sockets must be located below the pond water level, such that the minimum water level in the container
is 630 mm above the pit bottom (A-3). Otherwise the pond water cannot drain and cleaned in the filter system. Dan-
ger of running dry and, as a result, damage to the filter pump!
•
that the overflow openings in the internal covers of the module containers are located above the pond water level
and that the maximum water level in the container is 730 mm above the pit bottom (A-2). This is particularly impor-
tant, otherwise the filter cannot reach its maximum peformance, and, above all, because of the danger of fully emp-
tying the pond!
Important! Put the system out of operation if the min./max. values (A-3 and A-2) are exceeded, and especially
when fallen below. This means that the maximum permissible range of pond water level fluctuation is 100 mm.
Furthermore, take the following into account:
•
the thickness of the slab accommodating the modules has to be adapted to the local ground situation
•
ensure sufficient space for possible system extensions
•
ensure sufficient room for movement to be able to carry out cleaning and maintenance work.
Secure the walls of the pit against ground soil settling (masonry, concrete) and provide a rain water drain. Place the
filter system (M 1/ M 2/ M 3/ M 4) with a 30 mm gravity in flow direction on a stable and level ground (at least slabs,
concrete to be preferred). Due to the considerable volume, the weight of the filter modules in accordance with the
technical data has to be taken into consideration when selecting the base. For this operating mode, install a dry run-
ning protection (commercial float switch) in the pump chamber M 1 which switches off the filter pump should the water
level drop too low due to soiled filter modules.
