Product Information
Elix® 20, 35, 70 and 100 17
2-6 DESCRIPTION OF OPTIONAL COMPONENTS
QGARD TL1 POLISHING PAK (OPTIONAL)
PURPOSE OF THE QGARD TL1 POLISHING PAK
A QGard TL1 Polishing Pack can be added to an Elix System. The purpose of a polishing pack is to completely deionise the Elix
Module Product Water.
HOW CAN THE ELIX SYSTEM BE MADE TO USE A QGARD TL1 POLISHING PAK?
It is not possible to install a QGard TL onto an Elix System unless a Polisher Upgrade
Kit has been added. This kit is not factory installed.
The Polisher Upgrade Kit allows a QGard Pack Adapter and a Resistivity Sensor to be
added to an Elix System. When the Polisher Upgrade Kit is installed, a QGard TL1 Polisher Pak can be installed and used. The
software can then be reconfigured to include the display of the post QGard Product Water Resistivity measured by the Resistivity
Sensor.
See Section 6-2 for information about ordering the Polisher Kit (catalogue name RiOs/Elix-L Q-Gard® TL Kit).
WHAT ARE THE DIFFERENT TYPES OF QGARD TL1 POLISHING PACKS?
There is only one type of QGard TL Pak. See Section 6-1 for information about ordering it.
WHEN DO I CHANGE THE QGARD TL?
An LCD Message “EXCH. QGARD TL: PRODUCT < SETPOINT” is shown to indicate that the QGard TL Pack should be replaced.
This message is shown when the resistivity measured after the QGard is less than the Resistivity Setpoint. The Resistivity
Setpoint can be seen using the LCD. This message is not shown after a specific number of days. A timer is not used for the
QGard TL Pack lifetime.
LOOP RESISTIVITY SENSOR (OPTIONAL)
Another Resistivity Sensor can be added to an Elix System as an accessory. It can be used to measure the resistivity of water in a
distribution loop. The deionised Product Water is sent to a SDS 350 (a 350 L Storage Reservoir sold by Millipore SAS). The SDS
has a pump that sends pressurised water into a distribution loop. A sampling port is used to send some water from the
distribution loop to a resistivity cell. The measured resistivity is shown on the LCD as the DIST Resistivity.
The Loop Resistivity Sensor is not factory installed in the Elix System. It is available in an upgrade kit. The Resistivity Sensor is
then installed inside the Elix System. Water from the distribution loop goes to the sensor. It then goes out of the Elix System
back to the SDS.
The Loop Resistivity Values are displayed when the text DIST is shown on the LCD. If resistivity values are shown under the
heading PRODUCT, then the values are from the Elix System Product Water Resistivity Sensor.
