3 Installation and connection
3.1 Installation planning
NOTE
Use suitable transport and lifting aids to transport and install the unit.
The unit weighs more than 25 kg. (→ Technical data)
3.1.1 Optimum ambient and operating conditions
Optimum operating results can be obtained with careful planning, taking the ambient conditions into account.
•As the filter is very heavy when filled, it must be placed on a suitable base (at least on slabs, but preferably
on a poured concrete base) to prevent it from subsiding.
•Align the base slab horizontally.
•Ensure sufficient room for movement for carrying out cleaning and maintenance work.
•Allow the dirty water to drain out into a drain or far enough away from the pond to ensure that it cannot flow
back into the pond.
•Do not position the inlet into the pond higher than the outlet of the filter system (e.g. above a water course or
waterfall).
NOTE
A water course or waterfall guarantees optimum water return to the pond.
In this way, the filtered pond water is enriched with oxygen before it is returned to the pond.

3.1.2 Distance from the water
G
Electrical components of the filter system operate with a rated voltage of UDC = 12 V. The supply voltage is
supplied via an external transformer connected to the mains.
•Filter system with UVC clarifier fitted:
– The filter system and transformer must be located at a distance of at least 2 m from the water.
•Filter system without UVC clarifier fitted:
– The filter system can be installed directly next to the water. The transformer must be located at a dis-
tance of at least 2 m from the water.
3.1.3 Protective measures for swimming ponds
Adhere to the following conditions for dry installation:
H, I
•Only pumps with a voltage of ≤12 V permit immersion set-up.
•Pumps with a voltage of ≥12 V permit dry set-up, provided the required safety distance from the pond is
observed.
3.2 Connecting the inlet
The filter system has two inlets with stepped hose adapters.
•For connecting a filter pump
•For connecting a UVC clarifier (→ Connecting a UVC clarifier)
•If an inlet is not used, fit a closed stepped hose adapter.
– The stepped hose adapters are delivered closed.
Prerequisite:
•The container is open. (→ Opening the container)
•The screen holder is hinged up. (→ Hinging the screen holder up/down)
How to proceed:
J
1. Shorten the stepped hose adapter to the diameter of the hose used.
– This reduces pressure losses.
2. Insert the stepped hose adapter with flat seal into the inlet opening.
3. Screw the distributor nut with O ring onto the stepped hose adapter and hand tighten.
– BioTec ScreenMatic² 38000: Alternatively fit a 50 mm (2") hose connector.
4. Slip the hose clip over the hose, fit the hose onto the hose connector and secure with the hose clip.

3.3 Connecting a UVC clarifier
Prerequisite:
•The container is open. (→ Opening the container)
•The screen holder is hinged up. (→ Hinging the screen holder up/down)
How to proceed:
K
1. Fit the UVC clarifier with flat seal into the inlet opening.
2. Screw the distributor nut with O ring onto the stepped hose adapter and hand tighten.
– Read the UVC clarifier operating instructions.
3.4 Connecting the outlet
•Use suitable pipes.
•Do not use any right-angled bends. Bends with a maximum angle of 45° are very efficient.
•Standing water in pipes can freeze when there is a hard frost and cause pipes to burst. For this reason, lay
the pipes and hoses with a gradient (50 mm/m) to ensure that they can run empty.
•Pipe dimensions: (→ Technical data)
Fitting the DN 110 outlet
BioTec ScreenMatic² 38000: The outlet is not fitted on delivery.
Prerequisite:
•The container is open. (→ Opening the container)
How to proceed:
L
1. Fit the O ring onto the outlet.
2. 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.
3. 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.
NOTE
Build supports to increase the stability of the pipe construction and to prevent the pipe construction
from sagging at the discharge.
3.5 Connecting the dirt outlet
The water in the container can be drained via the dirt outlet with slide valve at the bottom of the container
when required (for cleaning, repair, overwintering).
•Connect the pipe and drain the dirty water, for example, into a flower bed or into the sewage system.
•Pipe dimensions: (→ Technical data)
3.6 Carry out the electrical connection
How to proceed:
M
1. Thread the connection cable through the opening in the container wall and seal off the opening using the
sealing plug.
– Ensure that the connection cable inside the container is sufficiently long so that it is not subjected to ten-
sion when the ScreenMatic rotating screen unit is hinged up.
– Avoid tangling of the cable inside the container.
2. Connect the plug of the connection cable to the socket on the transformer and hand-tighten the union nut.

4 Commissioning/start-up
NOTE
Remove the protective film from the substrate tubes and insert the substrate tubes into the container.
(→ Cleaning/replacing the substrate tubes)
•The substrate tubes are sealed in protective film on delivery.
•Thoroughly clean the pond before starting up the filter system for the first time to ensure that the filter system
is not overloaded by excessively soiled water. OASE recommends using the PondoVac pond vacuum cleaner
for cleaning the pond.
– This cleaning measure is normally not necessary for newly installed ponds.
•It is necessary to operate the filter system for 24 hours a day during the pond season.
4.1 Biological filter starter
The foam filters take several weeks to reach their full biological cleaning effect. We recommend using the
OASE filter starter Biokick to ensure fast growth of bacterial populations. Micro-organisms colonise the filter
system, multiply and ensure an enhanced quality of the pond water by the decomposition of excess nutrients.
NOTE
When using filter starter, medicines or pond water treatments, leave the UVC clarifying unit switched
off for at least 36 hours so as not to impair their efficacy.
4.2 Order of starting up steps
How to proceed:
1. Close the slide valve of the dirt outlet.
2. Check that the filter system (pipes and hoses) is complete.
3. Remove the container cover.
4. Connect the transformer for the control device to the power supply.
5. Switch on the filter pump and UVC clarifier (if applicable).
– Ensure that the water is returned to the pond via the return pipe.
6. Check all pipes, hoses and their connections for leaks.
– Expansion seals may leak initially until they have fully expanded on contact with water.
7. Adjust the control device to the flow rate if necessary. (→ Aligning the control device)
8. Check the function of the ScreenMatic rotating screen unit. (→ Operation)
9. Fit the container cover.
NOTE
The final water level is not reached in the container until the bacteria are established and the filter be-
comes fully effective.
•New foam filters take 3 to 4 weeks to reach their full biological cleaning effect. The water level is
initially lower; the foam filters are not completely covered by the water. The filter may overflow while
the beneficial bacteria colonies are being established. Do not clean the foam filters for 3 to 4 weeks.
•The biological cleaning effect ceases at temperatures under 10 °C. The filter may overflow.
Cleaning is not necessary.
NOTE
The substrate tubes should remain completely under water to ensure maximum effectiveness. De-
pending on the system configuration, the level of the water in the container may be too low for this.
•In this case, place the top substrate tube directly into the pond at a point where there is good water
circulation.

4.3 Aligning the control device
Do not align the control device until after the running-in period
•Lowering the pump into the pond may swirl up so much debris that starting up the filter system straight away
could cause the ScreenMatic screen to overflow.
•The filter system requires a running-in period of 2 to 3 hours. After this, the control device can be aligned if
necessary.
•Align the control device such that the sensor only switches when a well-formed line of debris has formed on
the screen.
– A well-formed line of debris can be optimally removed by the stripper and conveyed into the debris tray.
– The stripper brush under the ScreenMatic screen collects the fine debris, which falls into the debris tray.
How to proceed:
N
1. Remove the screw from the control device and take out the control device.
2. Insert the control device into the determined position, insert the screw and hand tighten.
Aligning the control device depending on the degree of soiling of the pond
In order to prevent premature soiling of the foam filters, ensure that the dirty water does not flow beyond the
"Max. water jet" mark directly into the debris tray.
•Do not change the position of the control device unless the water flows as far as or beyond the "Max. water
jet" mark, even when the ScreenMatic screen has been cleaned (with the enclosed brush).
