M4 screws and “Nyloc” nuts
supplied.

elbow by pushing in the collar
and pulling pipe out. Connect the
incoming air tube directly to the
new “T” connector.

vertical.

of the slots in the centre pipe. It is
recommended that the 45 litres
be taken from the biological
stage and replaced with the
Kaldnes supplied with your “Eazy”.

need to install a ball/slide valve to
the inlet pipe in order to control
the water level within the centre
chamber.
