1. Carry out a normal cleaning cycle on your Nexus
If you have an existing Nexus filter system, currently in use, clean it as you would do normally as part of
your maintenance routine prior to installing the Nexus Automatic System.
2. Disconnect your circulating pump from
mains power supply
Once the Nexus Automatic is installed, the power supply to the circulating
pump will come from the Nexus Automatic Control box rather than being
supplied directly from the mains. Turn off and disconnect the pump from
the mains supply.
If the circulating pump is connected to a plug, this will need to be cut off to
allow for direct connection into the control box.
3. Disconnect part of the air line for the Eazy and Bio-Chamber
Currently, the incoming air lines connected to the Eazy and the Bio-Chamber in your Nexus are diverted via a
T-Piece connector and are controlled by Air Valves. You will need to disconnect this T-Piece and the airline up
to the valves. We recommend that you leave the Air Valves and Air Lines to the Eazy and Bio-Chamber in place,
simply disconnect the T-Piece and leave both Air Valves in the OPEN position at all times. Discard the T-Piece
and the 2 small air lines, but keep the air line that connects your pump to the Nexus. This piece is needed for re-
installing your air pump.
New air valve assemblies can be ordered from EA:
Keep this length of air line
