9.5 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) .

9.6 Changing the foam filters
We recommend to change the foam filters (49) once a year, or whenever a gap forms between the foam
filter (49) and the inner cover (47) .
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) three 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, then remove the inner cover (47) including
the foam holders (13) out of the container (Figure S) .
7. Slightly lift the foam holder (13) by pulling, press in the blue engagement hooks (48) at the foam
holders (13) , then take out the foam holders (13) downward (Figure T) .
8. Pull the used foam filters (49) over the handle of the foam holder (12) by pulling and insert new foam
filters (49) in the opposite order (Figure U) .
9. Insert the foam filters in the reverse order.

9.7 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
