You can of course adapt to your special needs by selecting from the wide range of available
JBL filter media. Depending on your choice of filter media, this may influence the pumping
capacity of your filter and the length of time the filter media can be used.
Note: Regular maintenance and cleaning of the filter is vital to prevent a reduction in the
pumping capacity.

Cleaning or replacing filter media
Make sure to always disconnect the mains plug before carrying out any work on the
filter!
Turn the two small stopcock levers on the pump head to the stop position ( ) opposite the
"OPEN" mark. Lift the middle lever on the hose connection block as far up as possible and
push to the stop position. This slightly lifts the hose connection block out of its seat. Pull
upwards to lift the hose connection block out. The ball valves in the hose connection block
are now closed and retain the water in the hoses. This prevents accidental opening e.g. by
children and any associated unwanted leakage of water.
Open the 4 locking clips on the filter canister and remove the pump head.
Remove the filter baskets with the filter media and rinse the filter media in lukewarm water
(25°C). Never wash ALL the filter media at the same time, as too many beneficial cleansing
bacteria would be washed away. The JBL CristalProfi filters of the e range are designed so
that, as a rule, only the pre-filter material (F1) has to be cleaned whilst the remaining filter
material must be cleaned at longer intervals.
Tip: Do not forget to clean all the hoses and pipes regularly with an appropriate brush (e.g.
JBL Cleany), as bacterial deposits on the inside of the pump drastically reduce the pumping
capacity of the filter.

Function and replacement intervals of the individual filter media
(F1) JBL Pre-filter media
Mechanical pre-filter media made of coarse foam cut into a T-profile to absorb as much
coarse dirt as possible. These media should be changed every 2 months. They can be rinsed
once or twice.
(F2) High capacity biological filter balls (JBL MicroMec):
JBL MicroMec is a highly porous biological filter medium made from sintered glass and with
a special surface and pore structure, which provides excellent conditions for colonisation by
beneficial cleansing bacteria. This allows an effective biological breakdown of pollutants. It
