CLEANING

Gravity Fed
With a gravity setup, the level in the outer chamber (D) will lower as the Eazy
becomes dirty and the K1 in the Eazy will rise. By looking into the inner stainless
steel column on the Eazy you can see what height the water is passing through
the Eazy into the outer chamber. When the water level becomes low on the
steel slots and high turbulence is seen the Eazy should be cleaned.
Stop the circulation pump.1.
Wait a short period of time to allow the water levels within the Nexus to 2.
stabilise.
Close off the feed to the biological chamber by inserting the isolation pipe 3.
into the centre of the “Eazy”, ensuring that the rubber ange engages within
the Nexus centre spigot Fig 12.
Close the inlet to the Nexus by inserting inlet slide-plate (Fig1.4) supplied with 4.
your Nexus. Your Eazy is now isolated from the rest of the system.
Now clean the Eazy as in described in “Cleaning the Eazy” on page 10.5.
Remove the Nexus inlet slide-plate allowing the nexus to rell.6.
Remove the Isolation pipe.7.
Restart your pump.8.
Pump Fed
With a pump fed setup the level in the inner chamber (B) rises when the Eazy
becomes more blocked, the Eazy has to be cleaned before this level gets too
high and overows into the outer chamber (D).
Reduce ow to Nexus by closing single union ball valve most of the way, 1.
leaving valve partially open.
Close off the feed to the biological chamber by inserting the Isolation pipe 2.
into the centre of the “Eazy”, ensuring that the rubber ange engages within
the Nexus centre column Fig 12.
Watch the level in the inner chamber rise until the water level reaches the 3.
1” (25mm) below the top of the Eazy outer drum, then close the single union
ball valve. It is essential that this water level is maintained to allow efcient
cleaning.
Switch off the pond pump.4.
Now clean the Eazy as in described in “Cleaning the Eazy”5.
Open the single union ball valve and start pump.6.
Once the water level in inner chamber (B) reaches the level in the outer 7.
chamber (D) remove the isolation pipe.
