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 horizontally positioned (max. deviation d ± 5 mm).
– Tip: Use commercially available concrete slabs, each measuring 500 × 500 mm. One concrete slab
is required for the operation of the filter system on its own; four concrete slabs are required for
operation with ProfiClear Classic.
► 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.
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.
4.2 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.
► 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.
4.2.2 Connecting the inlet
The filter system is equipped with a 50 mm (2 ") or 38 mm (1.5 ") connection for the filter pump.
► You can additionally connect a UVC clarifier. (→ Fitting the UVC clarifier)
► The maximum flow rate is 12500 l/h.
► It is necessary to remove a screen element to access the internal connection. (→ Removing/fitting a
screen element)
► Leave the connection for the filter pump on the container closed if it is to remain unused.
How to proceed:

C
1. Unscrew the cover cap and remove the non-return valve and flat seal.
2. Screw the union nut with 50 mm (2 ") or 38 mm (1.5 ") hose connector and flat seal or non-return valve
onto the connection. Hand-tighten the union nut.
– Use the flat seal if continuous operation of the pump is planned, the non-return valve for interval
operation.
3. Slip the 50 mm (2") hose of the filter pump onto the hose connector and secure with a hose clip.
4. Screw the union nut with the 90° connection bend (2 ") and the seal onto the connection on the inside
of the container. Hand-tighten the union nut.
– Ensure that the connection bend points downwards.
– A correctly positioned connection bend prevents unintended overflow (emptying of the pond) and
also serves to reduce noise emissions.
