Product Information
Elix® 20, 35, 70 and 100 13
2-5 DESCRIPTION OF MAIN COMPONENTS
INLET SOLENOID VALVE
The Inlet Solenoid Valve is used to control the flow of feedwater into the Elix System.
The Inlet Solenoid Valve is located outside of the Elix System Cabinet. It receives 100, 120 or 230 VAC from the Elix System
via a 5 meter electrical cable. Typically, it is directly connected to a pipe carrying tap water.
FLOWMETER
A Flowmeter is installed inside every Elix System. It measures the total feedwater coming into an Elix System.
As a result of the Flowmeter, the RO Reject flow rate can be determined. This facilitates the manual setting of the RO Reject
flow rate (a procedure sometimes done at installation and during the lifetime of the Elix System).
PROGARD® TL SYSTEM PRETREATMENT PACK
PURPOSE OF THE PROGARD TL SYSTEM RETREATMENT PACK
The Progard TL System Pretreatment Pack (called “Progard TL” for the remainder of this manual) is used to prevent mineral
scaling, organic fouling and chlorine oxidation with the Reverse Osmosis (RO) Membranes. The Progard TL is a consumable
device that needs to be periodically replaced during the maintenance of an Elix System. The Progard TL is located on the left side
of the front of the Elix System cabinet.
It is possible to buy a type of Progard TL that has a chlorine sanitisation tablet inside. When this type of Progard TL is installed
on an Elix System, the chlorine sanitisation tablet will dissolve. This will sanitise the RO Cartridge located downstream of the
Progard. The dissolved chlorine will leave the Elix System via the drain and will never enter the Product Water Reservoir.
WHAT ARE THE DIFFERENT TYPES OF PROGARD PRETREATMENT PACKS?
There are 4 types of Progard TL Packs. The choice of a Progard TL is based upon 2 factors.
These factors are the Total Chlorine Level and the Fouling Index of the Feedwater. The type of Progard TL used is determined by
the magnitude of these parameters. You will be able to choose between a Progard TL1 System Pretreatment Pack (“Progard TL1”)
or a Progard TL2 System Pretreatment Pack (“Progard TL2”). You can choose either of these with or without a chlorine
sanitisation tablet inside.
WHICH TYPE OF PROGARD TL TO USE?
Please contact Millipore SAS. An Applications Specialist will be able to determine the appropriate pretreatment for your Elix
System.
WHEN DO I CHANGE THE PROGARD TL?
The Elix System will prompt you to change the Progard TL using a LCD Message. The Elix System will indicate a message
“EXCHANGE PT PACK IN 14 DAYS” when the projected Progard TL lifetime is 14 days. The Elix System will indicate a message
“EXCHANGE PT PACK OVERDUE: XXDAYS” if the Progard TL is not changed after 14 days.
The Progard TL is changed due to either the amount of time it has been used or from the amount of water that has passed
through it. The Elix System has the ability to measure the total volume of Feedwater passed through it. It also measures the
amount of time that elapsed since the Progard TL was exchanged.
Using these 2 parameters, the Elix System will be able to project a lifetime for the Progard TL. This lifetime is updated frequently
by the Elix System. The Elix System will display “N/A” for the Progard TL lifetime during the first 7 days that the Progard TL was
installed. After this, you will be able to see projected lifetime for the Progard TL.
