Maintenance and cleaning (Illustration 4)
Biotec filters are maintenance-free, however they should be
cleaned whenever necessary.
To drain the wastewater, pull out the slide-bar (1) in the intermedi-
ate base and the stopper (2) in the wastewater drain. This lets
the wastewater drain away freely. If necessary, some clean water
can be drained via the clear water outlet (3). This significantly
reduces the amount of dirty water.
1.Clean the filter brushes (4) as often as possible.
To do this,
rinse the brush frame. This can be done inside or outside
the container. The bottom end of the brushes should rest on
the black filter mat.
(Illustration 5)
2.Only clean the filter mats (5) when necessary.
They be-
come more effective as bacterial growth increases. The fil-
ter mats can also be cleaned inside or outside the con-
tainer. The filter mats 1-5 must be fitted in the correct order.
3.Clean the blue (6) and red (7) sponges when the water
through-flow is no longer adequate and the water level rises
above the sponges. The sponge holders can be easily pulled
out of the intermediate base to facilitate cleaning.
Only rinse filter elements with water. Do not use chemical
cleansing agents!
Directions for use
Start-up
1.Connect pump in pond via a hose to the adapter on the filter.
·
Cut adapter to right size to fit hose
·
If necessary, briefly dip ends of hose in boiling water
before attaching
·
Lay hose without twists and so that it cannot be stepped on
·
Affix hose clips to ends of hose
2.Lay domestic DN 100 drainage pipes from the filter outlet to
the pond inlet with a gradient of at least 1%. If the pipes are
not UV-resistant, possibly cover them with earth.Extend the
wastewater outlet with DN 70 drainage pipes.
3.Switch on pump and test water flow.
Special guidelines:
·
The hose connections on the filter must be fitted with care.
·
The filter must never overflow (e.g. due to a clogged drain).
Danger of pond emptying.
·
The filter system is a biological system and requires a few
weeks after initial installation to become fully effective.
·
The filter should be in permanent operation and never run dry.
