Solution
Check lever setting and adjust.
Remove safety adapter; open shut-off lever and clean openings with
cleaning brush (Order No. 4006570).
Check that there are no kinks or marked narrowing of cross-section.
Clean hose installation at regular intervals by drawing a universal
cleaning brush (Order No. 4006570) through the suction channels
and pressure channel or suction pipes and nozzle tube.
Remove coarse dirt, clean strainer.
Clean fi lter media.
Never put long-term fi lter media in net bags or nylon stockings. This
leads to a drastic reduction in pump performance within a short time.
When cleaning, remove the fi lter media from the fi lter media basket
and rinse through with lukewarm water.
Check that fi lter media have been assembled in the recommended
layers for fi ltering. Fill bottom fi lter insert to just under edge with
EHEIM MECH. Fill next two fi lter inserts with SUBSTRAT, also to just
under edge. Never place white fi lter pad under the handle.
After inserting the top fi lter insert, push in the handle and lay the
white fi lter pad on top.
Be sure to renew the fi lter pad each time you clean
(Order No. 2616805).
Clean pump chamber, cooling and lubrication channel with cleaning
brush set (Order No. 4009570) (see chapter on Servicing and
Maintenance).
Take fi lter into operation by priming (as described in the instructions).
Make sure that the water runback (delivery side) is above the surface
of the water during fi lling so that air is optimally bled from the device.
Connected accessories reduce fi lter performance. Check and
remove unnecessary accessories or operate via a separate water
circulation system.
Solution
Plug in to mains.
Renew shaft (see list of spares).
Fit impeller, clean pump chamber.
