Maintenance - JBL CristalProfi e700 Handbuch

and filter material will further reduce performance.
The following approximate capacities refer to a hose length of 1.5 m and operating with
the supplied filter material in a clean or new condition:
CP e700: 350 – 400 l/h
CP e900: 380 – 450 l/h
CP e1500: 800 – 900 l/h
The filter materials and hoses should be cleaned when these levels are reduced by
about 50 % .
Maintenance and care
All JBL CristalProfi external filters are supplied fully equipped with a standard filling of
filter material to provide clean and healthy aquarium water for "normal" operation. The
filters provide ideal conditions for the development of colonies of cleansing bacteria
which play an essential role in the breakdown of pollutants. Mechanical pre-filtering
ensures that these bacteria can efficiently carry out their task undisturbed for as long
as possible.
Note: Regular maintenance and cleaning of the filter is vital to prevent a reduction in
the pump capacity.

Cleaning or replacing filter material
The mains plug must be disconnected before any work is carried out on the filter!
Turn the two small stopcocks levers on the pump head to the stop position (●) opposite
the "OPEN" mark. Lift the middle lever up as far as possible and push to the stop
position. This lifts the hose connection block slightly. Pulling upwards, 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
leakage of water.
Open the 4 fastening clips on the filter container and remove the pump head.
Remove the filter baskets with the filter material and rinse the filter material in
lukewarm water (25°C). Never wash ALL the filter material at the same time as
too many beneficial cleansing bacteria would be washed away. The e-Series JBL
CristalProfi Filters are designed so that, as a rule, only the pre-filter material (F1) has
to be cleaned whilst the remaining filter material should only be cleaned at longer
intervals.
