5 Installation
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:
Model a b c (+ bottom slab height)
FiltoMatic CWS 7000 approx. 50 cm approx. 50 cm approx. 30 cm
FiltoMatic CWS 14000 approx. 50 cm approx. 50 cm approx. 50 cm
FiltoMatic CWS 25000 approx. 50 cm approx. 70 cm approx. 50 cm
►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.

6 Installation
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)
Installation of the inlet (Figure F)
1. Plug the inlet sheath (9) and the flat sealing (6) into the union nut (10) and tighten at the stop valve
thread (21).
2. Slide the hose clip (11) over the hose (24) arriving from the Aquamax. Push the hose on the inlet
sheath (9) and fasten with the hose clip.
Hose recommended by OASE: Spiral hose, green (OASE Order No. 52981)
Prior to the assembly, place the hose end in hot water for two minutes. It will then be easier to slide the
hose onto the inlet sheath (9).
Installation of the dirty water outlet (Figure F)
1. Fit the O ring (7) on the outlet sheath (8) and into the union nut (10). Then tighten to the thread of
the pre-assembled dirty water outlet (22).
2. Plug a DN40 pipe (23) onto the outlet sheath (8). Route the end of the DN40 pipe to a point where
the dirty water to be pumped out can trickle into the ground. Ensure a gravity of 1.5 % to 2 % for the
DN40 pipe.
As an extension for the dirty water outlet, OASE recommends the following:
−DN40 pipe, 480 mm, black (OASE Order No. 50307)
−DN40 pipe elbow, 45°, black (OASE Order No. 50308)

8.2 Setting the dirty water pump
In addition to the water temperature, the degree of soiling of the pond water greatly depends on the fish
population. The dirty water pump pumps out the dirt from the container bottom in intervals. The four
different cleaning programs allow individual adaptation of the interval for pumping off the dirty water
according to the degree of soiling. One cleaning cycle takes approx. 9 sec. and requires approx. 4 litres
of water. The table shows the cleaning program selection options. The cleaning program INTERVAL 1
includes the majority of cleaning intervals, INTERVAL 4 the smallest number of intervals. Select a
program that is best suited for the degree of soiling of the pond water. When delivered, cleaning
program INTERVAL 2 is set as a default.

8.3 Setting the UVC clarifying unit
The degree of soiling of the pond water by the formation of algae is notably determined by the water
temperature. With its UV light, the UVC clarifying unit operating under water removes green algae, as
such forming a significant component for pond water cleaning. Depending on the water temperature, the
UVC lamp of the UVC clarifying unit is switched on and off in intervals with the AU operating program. In
this manner it can be individually adapted to the degree of soiling. The following table shows the
operating program AU (Automatic) of the UVC clarifying unit as well as the operating statuses ON and
OFF.

10.1 Cleaning foam filters
Cleaning intervals depend on the degree of soiling of the foam filters. A higher water level in the soiling
indicator (Figure C, 12) in the inner cover signals that the foam filter cleaning capacity has decreased.
Cleaning is due from a degree of soiling of 75 % or in the event of an overflow at the latest.
How to clean the foam filters (Fig. H, I, J)
1. Open lid (1) with the rotary handle (2) and remove lid from the container (3).
2. Close the stop valve (17) by pulling it up.
−Pond water no longer flows into the container.
−Note: Water will spurt out of the air intake socket when closing the stop valve (17).
3. Pull foam filters (13) up several times.
−The foam filters will be compressed. The soiling will be washed out.
4. Press the PUMP key (C4) on the controller (15) for longer than 10 seconds.
−The LED (C2) is lit green. All of the dirty water in the container will be pumped out.
5. Open the stop valve (17) by pressing it down.
−The container fills up with pond water again.
Repeat the cleaning cycle if the foam filters are heavily soiled.
10.2 Remove and separate the cleaning components from each other
For cleaning and maintenance of the cleaning components of the dirty water pump (14) and the UVC
clarifying unit (16) it is necessary to take both out of the container. The controller (15) is fitted to the UVC
clarifying unit. The cleaning components are not permanently connected to the inner cover (47) but rest
in the guides of the inner cover (47) or of the stop valve (17) respectively.
This is how to remove the cleaning components (Figure K)
1. Open lid (1) with the rotary handle (2) and remove lid from the container (3) (Figure H).
2. Close the stop valve (17) by pulling it up.
−Pond water no longer flows into the container.

arrow on the top pipe (31) (Figure N).
4. Press the PUMP button (C4) once.
−The LED (C2) changes from red to green. The dirty water pump (14) starts up. Otherwise, the dirty
water pump (14) will not start up because of a malfunction. In this context, please refer to Chapter
Remedy of faults.
5. If necessary, clean the overflow on the top pipe (31). To this effect, open the soiling pipe cover (32).
10.4 Changing the UVC lamp in the UVC clarifying unit
Attention! Dangerous ultra-violet radiation.
Possible consequences: Severe injury to the eyes and the skin.
Protective measures: Only switch the unit on with the housing fitted.
The controller (15) does not show when the UVC lamp is defective. Check the function of the UVC lamp
by looking into the control window (18) at regular intervals (Figure O).
The operating life of the UVC lamp being limited, it has to be replaced once its useful life has elapsed
(please also refer to Chapter Checking the reading of the UVC clarifying unit operating counter).
1. Turn the water housing (35) until the symbol showing "Lock open" points to the arrow at the UVC top
pipe (34) (Figure O).
2. Pull off the water housing (35) (Figure O).
3. Remove the cleaning rotor (37) from the quartz glass tube (45) (Figure P).
4. Loosen the screw (40) from the union nut (39), then unscrew the union nut (39) (Figure Q).
5. Pull off the quartz glass tube (45) including the O ring (46) by a rotary movement (Figure R).
6. Pull off the UVC lamp protection (44) (Figure R).
7. Pull the UVC lamp (43) out of its position in the UVC top section (34) and replace (Figure R).

10.5 Checking the cleaning rotor
The cleaning rotor (37) cleans the quartz glass tube (45). The rotor is driven by the water flow in the
water housing (Figure P).
The constant rotational movement of the cleaning rotor (37) causes wear of the bearing bush (38). In
this case, the cleaning rotor (37) needs replacing (Figure P).
1. Turn the water housing (35) until the symbol showing "Lock open" points to the arrow at the UVC top
pipe (34) (Figure O).
2. Pull off the water housing (35) (Figure O).
3. Check the wearing condition of the bearing bush (38).
−When the bearing bush (38) has worn down to 0 mm, the cleaning rotor (37) needs to be
replaced (Figure P).
4. Reassemble the UVC clarifying unit in the reverse order.
−Important: The water housing (35) is only closed when the "Lock closed" symbol points to the
arrow on the UVC top section (34) (Figure O).
10.6 Changing the foam filters
We recommend to change the foam filters (49) once per year.
How to change the foam filters:
1. Open lid (1) with the rotary handle (2) and remove lid from the container (3) (Figure H).
2. Close stop valve (17) by pulling it up (Figure S).
−Pond water no longer flows into the container.
−Note: Water will spurt out of the air intake socket when closing the stop valve (17).
3. Pull up the foam holder (13) in the inner cover (47) several times. The water in the foam filters (49) is
pressed out (Figure I).
4. Press the PUMP key (C4) on the controller (15) for longer than 10 seconds (Figure J).
−The LED (C2) is lit green. The dirty water in the container will be pumped out.
5. Lift the cleaning components of the dirty water pump (14) and of the UVC clarifying unit (16) out of
the inner cover (47)(Figure K).
6. Release the blue engagement hooks (19) on both sides, and then remove the inner cover (47)
including the foam holders (13) out of the container (Figure S).
7. Slightly lift the foam holder (13), press together the two blue engagement hooks (48) at the foam
holders (13), then push the foam holders downward and out of the inner cover (47) (Fig. T).
8. Press in the four black engagement hooks (54) at the upper part of the foam and take out the foam
holder (13) downward including the filter cartridge (49) (Fig. T).
−Note: Press together the engagement hooks (54) arranged opposite of each other one after
another and push the hooks downward and out of the inner cover (47).
9. Remove the used filter cartridge (49) as well as the bottom part of the foam (55) from the foam
holder (13) (Fig. U).
−Dispose of the filter cartridge in accordance with the regulations.
10. Start by placing a new bottom foam part (55), on the foam holder (13), followed by a new filter
cartridge (49) (Fig. U).
−Ensure that the filter cartridge (49) fits exactly into the bottom foam part (55).
11. Insert the new foam holder (13) together with the new filter cartridge (49) into the inner cover from
below. While inserting, pull up the foam holder until the two blue engagement hooks (48) and the
four black engagement hooks (54) engage in the inner cover (Fig. T).
−Important: Perfect seating of the filter cartridge (49) is not guaranteed unless all four black
engagement hooks (54) are engaged.

10.7 Thorough cleaning of the unit
Light-weight suspended matter is mechanically filtered by the foam filters and, if necessary, biologically
broken down. Suspended matter heavier than water will sediment out and soil the container bottom.
Thoroughly clean the unit once per year, preferably when you prepare the FiltoMatic CWS for the winter.
Fully drain the container
Full drainage takes a maximum of 4 minutes.
1. Switch off the Aquamax pump.
2. Open lid (1) with the rotary handle (2) and remove lid from the container (3) (Figure H).
3. Pull up the foam holder (13) three times (Figure J).
−The foam filters will be compressed. The soiling will be washed out.
4. Press the PUMP (C4) key for longer than 10 seconds.
−The LED (C2) is lit green. The container is emptied.
−You can stop the drainage cycle by pressing the PUMP (C4) key once. Once the container if fully
drained, when the dirty water pump switches off no water flows through the transparent outlet
sheath (6).
Cleaning the unit
For this purpose, remove the lamella separator (51) and the dirt pyramide (52). To this effect, completely
empty the container and remove the inner cover (47). Please refer to the chapters above.
How to remove and clean the lamella separator
1. Press down the engagement hook (50) and pull the lamella separator (51) upward and out of the the
guide on the container (3) (Figure V).
2. Press in the engagement hook (52) at the lamella separator top (51) and fold out both sections of
the lamella separator (51) (Figure W).
3. Clean both parts using clean water and a soft brush.
4. Reassemble the lamella separator (51) in the reverse order
5. Insert the lamella separator (51) in the container (3) (Figure Y).
−Ensure that the engagement hook (50) engages at the stop valve (17).
How to remove and clean the dirt pyramid (Figure X)
Only remove the dirt pyramid (53) if necessary. A great deal of force is required for disassembly and re-
assembly.
1. Reach beneath the dirt pyramid (53) and detach the pyramid from the three holders at the container
bottom by vigorously pulling up.
2. Clean the dirt pyramid (53) using water and a soft brush.
3. Wash out the container bottom.
4. Plug the dirt pyramid (53) onto the holders by applying a large amount of pressure.
−The engagement in the holders is audible by a click.
An approx. 8 mm spacing is provided between the dirt pyramid (53) and the container bottom. This gap
allows the dirty water pump to pump off the dirt gathered at the container bottom. Take this spacing into
account during assembly. Do not attempt to press the dirt pyramid (53) fully down to the container
bottom by applying excessive force!
