We manufacture and sell water purification systems designed to produce pure or ultrapure water with specific characteristics
(µS/cm, T, TOC, CFU/ml, Eu/ml) when it leaves the water purification system provided that the systems are fed with water quality
within specifications, and properly maintained as required by the supplier.
We do not warrant these systems for any specific applications. It is up to the end user to determine if the quality of the water
produced by our systems matches his expectations, fits with norms/legal requirements and to bear responsibility resulting from
the usage of the water.

2-2 SYSTEM RECOVERY
WHAT IS RO RECOVERY?
An RO Cartridge has 1 feedwater inlet and 2 water streams exiting it. One exiting water stream is called the RO Permeate. The
other is called the RO Reject.
The RO % Recovery is a comparison of the RO Permeate flow rate to the RO Feedwater flow rate. It can be thought of as how
much water you ‘recover’ from the RO as a useful product.
It is calculated as:
% Recovery = [(Permeate flow rate / Feedwater flow rate] * 100%
Membrane % Recovery is defined as the recovery of a single RO Cartridge.
System % Recovery is defined as the amount of water produced relative to the amount going into the entire Elix System.
In most cases, the Membrane and System Recovery values will not be the same number.
ELIX SYSTEM RECOVERY
An Elix System can be operated with a System Recovery between 30% to 70%. This value will depend upon several factors
including the chemical makeup of the Feedwater.
System Recovery is defined above. See “What is RO Recovery?”
The Elix System Recovery is factory pre-set. If desired, the Elix System Recovery can be modified. Contact Millipore SAS for
assistance.
A System Recovery set too low will waste water. A low recovery occurs when a lot of RO Reject Water is sent to drain relative to
the RO Permeate flow rate (i.e. RO Recovery = 5%).
A System Recovery set too high can possibly cause the RO Cartridges to become clogged. A high recovery occurs when too little
RO Reject Water is sent to drain relative to the RO Permeate flow rate (i.e. RO Recovery = 80%).

2-4 DESCRIPTION OF INPUT AND OUTPUT CONNECTIONS
This section describes the use of the various ports and other connection places on the front left side of the Elix System Cabinet.
PORTS
PORT DRAIN 1
The DRAIN 1 Port is used to secure the 1/2 inch OD RO Reject Tubing. This port allows RO Reject Water to exit the Elix System.
PORT FEED 2
The FEED 2 Port is used to secure the 1/2 inch OD Feedwater Tubing. This port allows Feedwater to enter the Elix System.
PORT CONC. 3
This port is used to secure the 8 mm OD Elix Module Waste Water Tubing. This port allows Elix Module Waste Water to exit the
Elix System.
PORT PRODUCT 4
The PRODUCT 4 Port is used to secure 8 mm OD Product Water Tubing. This port allows Product Water to exit the Elix System.
PORT 5
Port 5 is used when a peripheral device is connected to the Elix System. This port could be used to allow water to enter the Elix
System to the device inside.
PORT 6
Port 6 is used when a peripheral device is connected to the Elix System. This port could be used to allow water to enter the Elix
System to the device inside.
PORT 7
Port 7 is used when a peripheral device is connected to the Elix System. This port could be used to allow water to enter the Elix
System to the device inside.
TANK LEVEL AND RS 232
TANK LEVEL
A Male Stereo Jack from an Analogue Level Sensor can be plugged into the Elix System here. The Supply Voltage coming from
this connection to the Level Sensor is normally 5 VDC but can be set to 24 VDC.
RS 232
This connection allows a 9-pin Male RS 232 Cable to be plugged into the Elix System. The Transmit and Receive voltages out of
or into this connection are 5 VDC when active.

Product Information
Elix® 20, 35, 70 and 100 12
GROMMETS
The grommets are not labelled with text on the front left side of the Elix System Cabinet. The grommet is a rubber device that
covers most of a hole drilled in the side of the cabinet.
GROMMET 1
The bottom grommet is designated as Grommet 1. The Electrical Cable going from the Elix System to the externally located Inlet
Solenoid Valve goes through this grommet. The voltage in this electrical cable is either 100, 120 or 230 VAC depending upon the
voltage supplied to the Elix System.
GROMMETS 2THROUGH 7
These grommets are used to allow an electrical cable to go into or out of the Elix System. The electrical cable(s) are used to
control or to power peripheral devices. The voltage in any one of these electrical cables is dependent upon the device being used
and the way that the device is interfaced with the Elix System PC Board.
