Installation

Lay the outlet pipe for the water outlet into the pond and the hose for the sludge drain into the sewage system or flower
bed (8) with a sufficient gravity (i.e. slightly downhill). Place the unit at a flood protected position at a distance from the
pond edge (7) of at least 2m on a firm and level ground. Ensure unrestricted access to the cover to be able to carry out
work on the unit. To avoid pressure loss, use hose connections which are as short as possible and have a maximum
internal diameter; avoid bends and lay well protected, saw off the open stepped hose nozzle (2) at the corresponding
mark. Push or turn the hose for the water inlet onto the open stepped hose nozzle and secure with a hose clip. Place a
flat sealing ring on the thread of the stepped hose nozzle, push the thread of the stepped hose nozzle through the
water inlet, insert an O ring on the thread from inside, screw the inlet nozzle on the stepped hose nozzle from inside
ensuring that the opening points downward. Close the second water inlet with the closed hose nozzle (except when
fitting an OASE UVC pre-clearing unit, e.g. Bitron C, Vitronic 18-36). Lay the hose so that it cannot be stepped on,
avoid kinks and connect it to the pump. During normal filter operation, the sludge drain should be closed using the
cover cap. To permanently fit a 2" hose to the sludge drain, unscrew the cover cap from the dirt drain, push the union
nut over the 2" hoze nozzle, push on the hose and secure with the hose clip, insert the flat sealing ring in the union nut
and firmly screw-tighten the 2" hose nozzle including the union nut on the dirt drain. As an option, you can permanently
fit a 1/2" connection for a garden hose to the fresh water connection (1) and to connect the OASE pond aerator
AquaOxy to the air connection to ensure an adequate oxygen supply to the pond.
Start-up
Prior to starting up the unit, check that all clamps on the internal cover are closed. The clamps for pond additives can
be used to supply additives such as filter starters to the filter and the pond (optional). Switch the pump on. Note: The
BioSmart filter is a biological filter system and requires several weeks after its first installation to reach its full biological
effect, and must be run continuously to retain the biological efficiency.
Maintenance and cleaning
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
• Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water:
Isolate the units and installations (switch off and disconnect from the power supply) before reaching into the
water.
• Isolate the unit before starting any work.
• Secure the unit to prevent unintentional switching on.
Only clean the unit 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 the filter system immediately when the float
switch in the water level indicator becomes visible from outside. Switch off the pump and open the unit cover.

Cleaning foam filters

To mechanically clean the foam filters, pull on the cleaning handles and "pump" (3) several times neither too strong nor
too fast. If necessary, unscrew the cover cap from the sludge drain, open the slide valve (4), allow the water to drain
completely, close the slide valve again; repeat the cleaning process 2 to 3 times, if necessary. If necessary, remove
the foam filters and clean more thoroughly in a bucket of pond water. To this effect, press the engagement of the
cleaning handles to the side until the connection to the inner cover disengages. Release the clamps at the inner cover
and remove cover. Pull the foam filters from the foam filter holder (6), spray clean the container, the inner cover, the
cover and the foam filters with clean water. Reinsert the cleaned foam filters in the foam filter holders (the green foam
filter in the black foam holder). Pull the handles of the foam filter holders through the slots in the inner cover from below
until the foam filter holders engage. Insert the inner cover into the filter container and fold over all clamps, fit filter cover
and switch on the pump. Replace the foam filters if the float switch of the water level indicator keeps showing a medi-
um to heavy soiling following the cleaning process.
Cleaning the water level indicator
Turn the water level indicator counter-clockwise (5) through approx. 30° and pull 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.
