300 Installation
1) Drain the Nexus central chamber
2) Remove the central and exit
foams from your Nexus.
3) Remove the existing black spigot
(later models having 3 retaining
screws).
4) Using the template supplied, drill
two 4mm holes in the side of the
inner chamber.

5) Fit the two air-pipe clips using the
M4 screws and “Nyloc” nuts
supplied.
6) Remove the current 90° air-pipe
elbow by pushing in the collar
and pulling pipe out. Connect the
incoming air tube directly to the
new “T” connector.
7) Connect the existing air-ring air
tube to the lower connection on
the “T” connector.
8) Connect the new backwash air
tube to the “Eazy” aeration ring

9) Install the “Eazy” over the spigot in
the Nexus central chamber.
10)Align the air tube as shown,
ensuring that the “Eazy” support
legs are positioned equally either
side of the waste drain.
11)Connect the new back wash air
tube to the other side of the air
valve.
12)Fit the stainless steel centre pipe
over the central spigot in the
Nexus, aligning the top of the
pipe with the top edge of the
“Eazy”, ensuring that the pipe is
vertical.

13)Position the supplied Jubilee Clip
(band clamp) at the base of the
centre pipe and tighten fully.
14)Fill the “Eazy” with 45 litres of
Kaldnes. The volume of Kaldnes
will be found when levelled, to
correspond with the lower edges
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”.
15)On pump fed installations, you will
need to install a ball/slide valve to
the inlet pipe in order to control
the water level within the centre
chamber.
16)On pump fed installations push
the adjustable collar on the exit
stand pipe to its lowest setting

8) Connect the new backwash air
tube to the “Eazy” aeration ring

9) Install the “Eazy” over the spigot in
the Nexus central chamber.
10)Align the air tube as shown,
ensuring that the “Eazy” support
legs are positioned equally either

12)Fit the stainless steel centre pipe
over the central spigot in the
Nexus, aligning the top of the

“Eazy”, ensuring that the pipe is
vertical.

13)Position the supplied Jubilee Clip
(band clamp) at the base of the
centre pipe and tighten fully.
14)Fill the “Eazy” with 30 litres of
Kaldnes. The volume of Kaldnes
will be found when levelled, to
correspond with the lower edges
of the slots in the centre pipe. It is
recommended that the 30 litres
be taken from the biological
stage and replaced with the
Kaldnes supplied with your “Eazy”.
15)On pump fed installations, you will
need to install a ball/slide valve to
the inlet pipe in order to control
the water level within the centre
chamber.

Cleaning
To achieve optimum water clarity we recommend that the “Eazy” be air
backwashed and purged on a regular basis. The frequency of cleaning will
depend on the loading of the pond. The longer the filter is left undisturbed the finer
the filtration will become. However the filter must be purged regularly to avoid
circulation pump starvation on a gravity system or chamber overflow on a pump
fed system.
Gravity Procedure
1) Stop the circulation pump.
2) Wait a short a period of time so as to allow the water levels within the Nexus
to stabilise.
3) Close off the feed to the biological chamber
by inserting the Isolation pipe into the centre of the “Eazy”,
ensuring that the rubber flange engages
within the Nexus centre spigot.
4) Close the inlet to the Nexus by using the inlet slide-plate supplied with your
Nexus. You should now have isolated your “Eazy” from the System.
5) Open the air valve until the Kaldnes in the “Eazy” is boiling.
6) After the “Eazy” has been boiling for a minimum of one minute, open the
Nexus central chamber waste valve.
7) Once central chamber has drained, close waste valve.
8) Close the air valve.
9) Remove the Nexus inlet slide-plate allowing the Nexus to refill.
10)Remove the Isolation pipe from the centre of the “Eazy”.
11)Restart the circulation pump.

Pump Procedure
1) Close inlet valve.
2) Close off the feed to the biological chamber
by inserting the Isolation pipe into the centre of the “Eazy”,
ensuring that the rubber flange engages
within the Nexus centre spigot.
3) Re-open inlet valve until the water level within the Nexus central chamber is
level with the overflow, close inlet valve. It is essential that this water level is
maintained to allow efficient cleaning.
4) Switch off the pond pump.
5) Open the air valve until the Kaldnes in the “Eazy” is boiling.
6) After the “Eazy” has been boiling for a minimum of one minute, open the
Nexus central chamber waste valve.
7) Once central chamber has drained, close waste valve.
8) Close the air valve.
9) Open inlet valve.
10)Remove the Isolation pipe from the centre of the “Eazy”.
11)Restart the pond pump.
