Function and replacement intervals of the different filter materials
(F1) Pre-filter material
Mechanical pre-filter material made of coarse foam cut into a T-profile to absorb as
much coarse dirt as possible. This material should be changed every 2 months. The
material can be washed once or twice.
(F2) Ceramic rings (JBL CerMec):
Mechanical filter material, which also works biologically through colonisation by
cleansing bacteria. The ring shape allows the flow of water to be channelled through in
any direction, guaranteeing optimum circulation through the filter. Cleaning is required
every 6 – 12 months, depending on the amount of dirt. Replace when the dirt can no
longer be washed out.
(F3) Filter sponge (JBL UniBloc):
Medium-pored foam pads for effective biological filtering with ideal conditions for
colonisation by cleansing bacteria. The pads have a section which can be removed
and replaced with filter material to treat specific problems. Careful cleaning is required
approximately every 6 months. Replace after cleaning 2 to 3 times. Only one of the two
pads should be cleaned or replaced at a time.
(F4+F5) Combi filter sponge
Set of one medium-pored foam pad and one fine-pored pad for the middle section of
the combi-filter basket. The medium-pored pad uses colonisation by cleansing bacteria
to filter biologically. The fine-pored pad retains any particles of dirt which could damage
the pump, as well as filtering biologically. The medium-pored pad should be cleaned
approximately every 6 months. The fine-pored pad should be cleaned about every
4 months or as required (reduction in pump capacity). Replace after cleaning 2 to 3
times.

Cleaning the hoses
Bacteria settle in the hoses, producing slime which can significantly obstruct the
flow of water. Algae growth only occurs in strong light. Clean the hoses regularly
with a cleaning brush (e.g. JBL Cleany). Simply rinsing the hoses in tap water is not
sufficient!

Cleaning the impeller and casing
Turn the cover of the impeller casing anti-clockwise in the direction "Open" and remove
the cover by pulling gently.
Take the impeller out of the casing. CAUTION: the impeller is held in the casing by
magnetic force. Take appropriate care when removing the impeller, particularly to avoid
any injury to fingers.
The ceramic shaft is held by two rubber bearings, which remain either on the shaft
or on the bottom of the impeller casing or in the middle of the casing cover when the
impeller is removed.
Clean the impeller casing, impeller and shaft with a suitable cleaning brush, then
rinse in clean water. Limescale can be easily removed by soaking in JBL BioClean A
