Item code: EH2229
As an external filter the Eheim Professionel Wet/Dry Filter is
the first filter to offer the perfect technology of a "breathing" alternating
contact with the filter medium. The bacteria colonies are rhythmically flushed
and aerated. This creates ideal conditions for considerably accelerated
decomposition of almost all solved pollutants.
The Eheim Professionel wet/dry filters offer efficiency surpassing that of a
tricle filter. The water movement within the filter is bi-directional allowing
for extended contact time between bacteria cononies, oxygen and toxinx, which
are thus decomposed much more rapidly than in a traditional filter.
Faster decomposition of
pollutants than with conventional pot filters: ammonium by 73%, nitrite by
Exchange of oxygen and CO2
is accomplished by means of displacement through the specially designed
The water output pulsates as
the filter fills and empites, acheiving a wavelike action.

How to start the Siphon on the Professional
Wet/Dry Models 2227, 2327, 2229, 2329
When first setting up your filter, NEVER fill the canister up with water. Rinse
the Ehfisubstrat and put the media baskets in, close up the canister with NO
water in it. Open the tap connector of the intake pipe (IN) and apply suction
briefly at the breather pipe. The filter will automatically fill up with
water. After it finishes filling, open the tap connector of the outlet pipe
(OUT) and proceed to plug the unit into an electrical outlet. The filter will
automatically start up.
When you need to service the filter, wait until it starts draining, shut off the
tap connector of the intake pipe (IN), wait until the canister empties of all
it`s water and the flow in the outlet pipe stops. Proceed to shut off the tap
connector of the outlet pipe (OUT) and then unplug it from the electrical
outlet. By doing this, you preserve the siphon in the tubing, don`t have to
carry around a canister full of water and wont make the mistake of leaving water
in the canister.
NOTE: If all the above steps have been followed and the filter is making noise
but has not started up, close both tap connectors unplug the unit from the
electrical outlet and lift the double tap connector unit up, this will drain
the water out of the breather tube. Close and lock the double tap connector
unit back onto the canister. Open both the intake (IN) and outlet pipe (OUT)
tap connectors plug it back into electrical outlet.
