4.2 Fitting the filter container
T I P
The filter system operates day and night and causes rinsing noises during the automatic cleaning
cycles.
► Please protect the general public and your neighbourhood from noise disturbance and comply with
the statutory noise regulations.
► Enclose the filter sy stem such that the enclosure effectively absorbs the noises.
► Select the location of the filter system in order to avoid noise disturbance.
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 (maximum deviation ±0.2 in (±5 mm).
– Tip: Use commercially available concrete slabs, each with a size of approx. 19.7 × 19.7 in
(500 × 500 mm) . Five slabs are req uired (one base slab for each corner and 1 for the centre).
► Plan sufficient space for carrying out cleaning and maintenance work.
► Drain the dirty water into the sewer system or far enough away from the pond to prevent it from flowing
back into the pond.
– If the coarse dirt and dirty water both run into the same pipe, use at least ∅ 4 in (DN 110) pipes for
this purpose.
► Position the inlet in the pond (e.g. via a stream or waterfall) so that it is lower than the outlet of the
filter system.
T I P
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.
