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).

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.
Lift the cleaning components of the dirty water pump (14) and of the UVC clarifying unit (16) out
5.
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.
