Installation (A)
Lay the outlet pipes for the water outlet into the pond and for the drain outlet into the sewage system or flower bed with
a sufficient gravity. Ensure that the unit is placed at a flood protected place and on firm ground (A1). When installing an
OASE UVC pre-clarifying unit (e.g. Bitron), place the unit at a minimum distance of 6.6 ft (2 m) from the pond edge
(A1). Place the transformer at a minimum distance of 6.6 ft (2 m) from the pond edge at a flood protected place (A1).
Ensure unrestricted access to the cover to be able to carry out work on the unit. Push (A2) or turn the hose onto the
stepped hose nozzle and secure with a hose clip. Push the flat sealing ring on the stepped hose connection, insert the
stepped hose connection into the inlet opening of the filter housing, and screw-tighten the water inlet socket from inside
(A2). Close the second water inlet with the closed hose nozzle (except when fitting a OASE UVC pre-clarifying unit,
e.g. Bitron). Lay the hose such that it will not deform when walked on, avoid kinks and connect it to the pump.
Fitting the DN 110 outlet (BioTec 32000)
How to proceed:
 Fit the O ring onto the outlet.
 Fit the outlet into the respective hole of the container wall from the outside.
Ensure that the raised marking is at the top and aligned in relation to the hole pattern.
 Fasten the outlet from the inside with oval head screws.
– Tighten all screws diagonally using the cordless screwdriver to ensure that the sealing ring is uniformly applied.
Further tighten the screws using a Phillips screwdriver.
Start-up (B)
Switch on the pump, open the unit cover, set the water jet using regulator at the water distributor (B2) such that it hits
the first third of the screen. Close the cover, connect the motor connection cable to the transformer, connect power
plug (B1). The unit functions automatically, cleaning is every 30 minutes. Note: The Biotec filter is a biological filter sys-
tem and requires several weeks after its first installation to reach its full biological effect.
Maintenance and cleaning ( C )
Adhere to the safety information given above! Always unplug the power cables of the pump and of the Screenmatic
prior to starting work (B3)! Only clean the filter when required, do not use chemical cleaning agents to permit the filter
biology to optimally develop, knowing that cleaning agents kill the bacteria in the foam filters.
Clean and change the Screenmatic screen
Open the unit cover, remove and empty out the collection container (C1). If required, rmove the Screenmatic insert
(C2). For this purpose, tilt up the screen insert, loosen the sealing plug of the power cable from the container wall in-
ward, pull the power cable inward through the container wall, press in the lateral engagement hooks on the Screen-
matic insert and remove same. Press the Screenmatic unit of Biotec 36 to the rear (C2), then remove. Undo the lateral
screws (C3) from the side section without motor, remove side section, release the clamping lever (C4), and remove the
Screenmatic screen to the front. Thoroughly clean the Screenmatic screen, the strippers, and the screen from both
sides under running water. Replace the screen, if necessary. Reassemble the Screenmatic insert in the reverse order,
lead the power cable through the opening in the container wall and close the wall using the sealing plug.
Clean and replace the foam filters, clean the substrate tubes or change the substrate
Open the unit cover and tilt the screen insert upward (C5). To mechanically clean the foam filters, place the cleaning
tool on a foam holder and compress the foam inserts several times; if necessary, remove the foam filters (C6) and
rinse with clean water. Remove the separating plate between the filter and substrate chamber. Open the cleaning out-
let using the slide valve until the water has completely drained, close and switch the pump on until the filter is com-
pletely filled with pond water. Open the cleaning outlet again and drain the water. Repeat rinsing 2 – 3 times. Remove
the substrate pipes, clean under running water, or replace the substrate. Re-insert the substrate tubes in the guides,
refit the separating plate, tilt the screen insert down again and close the filter cover, then switch the pump on again.
Storage/Over-wintering
 Put the unit out of operation at water temperatures below 46 °F (8 °C) or, at the latest, when freezing temperatures
are to be expected.
 Drain and thoroughly clean the unit, check for damage.
 Remove, clean, dry and store all filters in a frost-free environment.
 Ensure that the storage place is inaccessible to children.
 Cover the filter container such that the ingress of rain water is excluded.
 Drain all hoses, pipes and connections as far as possible.
