3.1.1
Optimum ambient and operating conditions
Optimum operating results can be obtained with careful planning, taking the ambient conditions into account.
• As the filter 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.
• Align the base slab horizontally.
• Ensure sufficient room for movement for carrying out cleaning and maintenance work.
• Allow the dirty water to drain out into a drain or far enough away from the pond to ensure that it cannot flow
back into the pond.
• Do not position the inlet into the pond higher than the outlet of the filter system (e.g. above a water course or
waterfall).
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.
