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.
