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.
Note:
• Check and clean the water outlet into the pond at regular intervals.
• Clean the filters at regular intervals (e.g. every four weeks), however, at the latest when cloudy or dirty water from
the water outlet returns to the garden pond.
• Carry out quick cleaning first. Should this prove insufficient, clean the entire unit.
• A blocked filter could lead to leakages.
• Never use chemical cleaning agents.
Quick cleaning
How to proceed:
D
• Switch off the filter pump.
• Remove hose from the filter outlet by turning off the union nut (1).
• Remove hose from the filter inlet by turning off the union nut and screw on the filter outlet (2).
• Screw a dirt drain hose with stepped hose adapter on the filter inlet.
• Switch on the filter pump.
• Vigorously pull on the cleaning handle and „pump" several times (3). In this manner, the foam filters are mechani-
cally cleaned until the draining water is clear.
• Switch off the filter pump.
• Remove the dirt drain hose and correctly reconnect the hoses for normal operation (Figure A).
Thoroughly cleaning the unit
How to proceed:
E
• Disconnect all hoses by turning off the union nuts (1).
• Open the closing clamps of the filter container (2).
BioPress 4000: Hold the filter container at the hold-down element and lift off cover including the foam filter pack-
age (3).
BioPress 6000/10000: Lift off cover including foam filter package (2)
• Place the cover upside down onto a soft, clean surface, so that the foam filters with the press ring face up (4).
• Remove the press ring by undoing the nut from the pulling rod (4).
To remove the nut, hold the pulling rod using combination pliers.
Note: Do not pull the pulling rod out of the cover.
• Pull off the foam filters (5).
• Clean under running water by vigorously compressing and releasing (6). Clean the bioballs, container, cover with
meshed tube and press ring under running water (6).
• Push on foam filters such that the pulling rod rests in the recess of the foam filters (7).
• Fit the pressing ring with the rod guidance pointing down, and screw the nut onto the pulling rod (8).
To tighten the nut, hold the pulling rod using combination pliers.
BioPress 6000/10000: Ensure that the meshed tube fits completely in the ring diameter.
• Remove the cover sealing ring from the container and check for damage; clean or replace, and place on the top
container rim.
• Press on the cover including the foam filter package, allow the closing clamps to engage (9).
• Perform a quick cleaning (see 'quick cleaning').
