We recommend to thoroughly clean the garden pond to ensure almost maintenance-free operation of
the FiltoMatic CWS from the very beginning. OASE's recommendation for this cleaning work is the use
of the pond sludge suction unit Pondovac. In general, cleaning work can be omitted when the FiltoMatic
CWS is used in a newly installed garden pond.
Installing the FiltoMatic CWS (Figure D,E)
Plan the installation of the FiltoMatic CWS. Careful planning and taking the environmental conditions
into account will lead to optimum operating conditions for the FiltoMatic CWS. The following points can
help you with your planning.
►
A water course guarantees optimum water return from the FiltoMatic CWS to the garden pond. In
this manner, the filtered pond water is enriched with oxygen prior to returning to the pond. Should
the local situation not allow the installation of a water course, extend the outlet using a DN70 pipe for
the filtered water to return to the pond via the pipe. Please refer to the Installation chapter for the
installation of a DN70 pipe.
►
Horizontal alignment of the FiltoMatic CWS is crucial to prevent drainage of the pond in the event of
an overflow. Carry out the alignment using a spirit level.
►
Take the large volume of the FiltoMatic CWS as well as the resulting weight when filled into account.
Select a suitable ground or a bottom slab in the pit to prevent the FiltoMatic CWS from sagging.
►
Plan sufficient space for movement to be able to carry out cleaning and maintenance work.
►
Dig a suitably dimensioned pit for the installation of FiltoMatic CWS (Figure D). Take into
consideration that the FiltoMatic CWS can be buried up to the top recess (Figure E, height c).
Please use the following table as a basis for the pit dimensions:

►
Fill the container (3) with water prior to backfilling the soil to avoid compressing the container.
►
Route the DN40 pipe end for the dirty water outlet at a distance from the pond that prevents the
pumped out dirty water from flowing back into the pond.

Installation of the FiltoMatic CWS
The FiltoMatic CWS is delivered pre-assembled. Assembly is reduced to the outlet and the inlet and
dirty water outlet connections.
The outlet sheath (8) for the dirty water outlet is transparent. In this manner, the degree of soiling of the
outflowing water is visible during future cleaning. Pumping can be stopped as soon as visibly clean
water flows out of the dirt outlet. Cleaning is then completed.
Installation of the outlet (Figure F)
1. Place the flat sealing (5) over the outlet screw (25) pre-fitted on the housing.
2. Screw the outlet (4) on the outlet screw (25).
3. If necessary, connect a DN70 pipe (26) to the outlet (4) as an extension to allow the filtered pond
water to return into the pond. Ensure a minimum incline of 1.5 % for the DN70 pipe.
As an extension for the outlet, OASE recommends the following:
−
DN70 pipe, 480 mm, black (OASE Order No. 55034)
−
DN70 pipe elbow, 45°, black (OASE Order No. 55044)
−
DN70 pipe elbow, 87°, black (OASE Order No. 55045)
−
DN70 pipe elbow, T, black (OASE Order No. 55046)
