Connecting the modules (H)
Push the O ring (H-1) onto the outlet socket DN 150/1 up to the first recess (H-2). Push the inlet socket DN 150/2 of the
next module onto the outlet socket DN 150/1 up to the stop (H-3). The O ring will then roll into its final position.
Installation of the air connection (H)
Push the oxygen stone holder (H-5) onto the outlet socket of the previous filter module from inside. Connect the air supply
line (H-4) to the oxygen stone (H-6) and route it in the guide of the oxygen stone holder and over the container rim to be
able to connect a OASE pond aerator (e.g. Aqua-Oxy).
Installation of an optional IVC pre-clearing unit to the system outlet (module M 1 pump chamber)
Principle of gravity (I): Use a 100 mm bit to drill through the cavities in the container wall with the outlet opening from
inside the container. Fasten the Bitron holder (optional) at the container (outside). Use the connection set to connect the
water inlet of the UVC pre-filtering unit (Bitron from OASE) with the outlet of the pump chamber M 1 and screw connect
the rear feet with the Bitron holder.
Installation of the system outlet
– Principle of gravity (F): Fasten the connection set at the pump chamber M 1 outlet. To avoid pressure loss, minimise
the length of the hose connection having a largest possible internal diameter without bends and well protected, then
saw off the stepped hose nozzle at the appropriate points for the individual hose. Heat the hoses in hot water, push or
screw onto the stepped hose nozzle and secure with a hose clip.
– Pumped systems: Connect a DN 100 pipe to the water outlet and route it as straight as possible (max. 45 ° bends) and
well protected.
Installation of the dirt drain
The dirt water contains, amongst others, fish manure and has to be disposed of in accordance with the valid legal
regulations. The dirt drains of the filter system are connected to a DN 50 pressure pipe to be laid with a 30 mm gravity in
flow direction.
Starting up and checking the correct function
Important! Ensure that in the filter mode the stop valves of the dirt drain are always closed! Otherwise danger of
completely emptying the pond.
Adhere to the safety information given above! Prior to starting up, check if all remaining hooks at the inner covers of the
filter modules (M 2/ M 3/ M 4/ M 5) are firmly closed and if all connected hoses and pipes are correctly connected. Open
the slide at the system inlet, switch on the pump, check the system for leaks.
Note: After a new installation, the system only reaches its full biological cleaning effect after a few weeks. Full bacteria
activity only starts from an operating temperature of + 10 °C, which can be checked at the control thermometer of the filter
modules (M 2/ M 3/ M 4/ M 5).
Maintenance and cleaning
Adhere to the safety information given above! Only clean the unit when required, do not use chemical cleaning agents to
allow the filter biology to optimally develop, knowing that cleaning agents kill the bacteria in the foam filters. At the
beginning, this entails a reduced filter capacity. Clean the filter system immediately when the float switch in the water level
display is visible from outside (only with pumped systems). Switch the pump off and secure against unintentional
switching on again, close the slide at the system inlet, remove the filter module cover.
Cleaning the water level indicator (such display....
Pull the water level indicator out of the inner cover. Remove the plug and the float switch out of the housing of the water
level indicator and clean using clear water. Reassemble in the reverse order such that the float switch can move freely in
the housing.
Module M 2 (coarse dirt separator): Cleaning the Screenex cylinder (J)
Turn the rotary handle of the Screenex cylinders forward and backward several times: The cylinder is cleaned by brushes
at the inner and outer walls. If necessary, release the cylinder holder, remove the Screenex cylinders and thoroughly
brush and rinse them from the inside and outside under running water.
Module M 2 (coarse dirt separator): Replacing the cleaning brushes (M)
If the cleaning brushes of the Screenex cylinder are worn, release the cylinder holders, and remove the Screenex
cylinder. Loosen the nuts of the brush holders on the inside and outside, remove worn brushes, push new brushe into the
guide, refit the nuts, insert the Screenex cylinders in the container and secure with the cylinder holders.
Modules M 3 (foam filter) und M 5 (phosphate binder): Cleaning foam filters (K) and replacement (N)
To mechanically clean the foam filters, pull on the cleaning handles and "pump" several times neither too strong nor too
fast. Open the slide until the water has completely drained, close the slide again, repeat the cleaning process 2 to 3 times,
if necessary. If necessary, release the engagement hooks of the inner cover (L), remove the inner cover with the foam
filters, release the foam holder plates from the foam holders, pull off the foam filters and clean under running water. If
necessary, replace the foam filters.
Cleaning processes applicable to all filter modules M 1 - M 5 (J, K)
After cleaning the filter elements, open the slide of the dirt drain and wait until the pond water has drained and the
containers are empty. Fit a fresh water hose to the spray system (except M 1) and supply fresh water. Once the
containers are rinsed inside and the water has drained, firmly close the slide again and fill the containers with fresh water
up to the drain level. Once the cleaning process is completed, reopen the slide at the system inlet, switch on the pump,
check the system for leaks, close the filter module cover.
Storage/Over-wintering
Put the system out of operation at water temperatures below 8 °C or, at the latest, when freezing temperatures are to be
expected. Drain and thoroughly clean the system, check for damage. Cover the filter containers such that the ingress of
rain water is excluded. Drain all hoses, pipes and connections as far as possible and leave the slide valve of the filter
modules open.
