Solution
Check positions and correct them
Remove hoses and use suitable brushes to clean
hose connection block whilst in position with
stopcocks in "OPEN" position
Check hoses for kinks, constrictions etc.
Clean intake strainer
Clean hoses with cleaning brush
Clean filter material (particularly pre-filter
material).
Do not fill long-term biological filter material e.g.
JBL MicroMec, JBL Sintomec etc. in finely meshed
net bags. For special problem solutions, only use
the original CristalProfi filter material with the
appropriate foam edge.
Remove filter material from filter basket and
clean.
Fill fine filter material e.g. filterwool loosely
into the filter baskets so that water flow is not
obstructed.
Clean pump chamber, impeller and cover with
cleaning brush (10)
Repeat start procedure (5)
Dismantle, check, replace faulty parts and re-
assemble. Check shaft and bayonet lock correctly
positioned.
Accessories (e.g. UV-C clarifier etc.) reduce water
flow. Remove accessories or operate with own
separate water circulation.
Solution
When carrying out a partial change of water,
siphon off water to approx. 5 cm above the
connection only. Otherwise disconnect plug.
The top of the pump head should be at least 20
cm below the surface of the water, the further the
better.
