The Milli-Q® EQ 7000 oers 2 congurations:
Benchtop solution and Wall-mounted solution
Description of the system
The Milli-Q®EQ 7000 manages the production and the distribution of ultrapure water from a
puried water source such as a tank or a pressurized loop. It consists of three main units:
• The water purication unit manages the production of ultrapure water.
• The Q-POD unit manages the dispensing with Quick info for the performance of the system
through LEDs.
• The HMI unit provides the user interface.
Puried water either from a pressurized loop or a storage tank enters the purication unit.
It is rst puried by the IPAK Meta®polishing cartridge composed of ion-exchange resins,
removing the bulk of the ions. The puried water then ows to the UV 185nm oxidation lamp.
Organic molecules are partially oxidized, resulting in ions. These can then be captured in the
next stage when the puried water enters the IPAK Quanta®polishing cartridge, composed of
ion-exchange resins and synthetic activated carbon. The IPAK Meta and IPAK Quanta polishing
cartridges always need to be replaced together to ensure optimal purication down to trace
levels of contaminants. Throughout the purication steps, quality parameters are monitored
with resistivity and temperature sensors and the TOC (total oxidizable carbon) indicator. The
TOC indicator gives an indication of the total organic content measured in ppb at the point of
distribution.
System overview
Milli-Q® EQ 7000 consists of 3 main parts:
Q-POD® unit Water purication unit HMI
(Point Of Dispense) (Human Machine Interface)

Introduction 3
The Q-POD dispenser is detachable from its support. Its dispensing ‘wheel’ delivers water at 3
dierent ows: Low - Medium - High, up 2 L/min.
At the outlet of the dispenser, the nal purication is performed by the application-specic POD-
Pak. The large 7” touchscreen on the HMI oers a wide range of applications for users. It also
has a USB port to easily export data.
Note: High ow reaches above 2L/min when attached to a pressurized loop
When not in active use, the water within the system will recirculate for three minutes every hour.
This is to maintain a clean environment and to avoid contamination. The system should not be
turned o as this will stop the periodic recirculation taking place.

Volumetric Dispensing (100mL to 10L)
Enables a user to auto dispense a pre-selected volume.
Note: When connected to a storage tank, always make sure there is enough water
present before dispensing. This information is always displayed in the status bar:
Select the volume to dispense, press ok to
validate. The input value can be customized,
go to page 14 Settings > System conguration
Press the Play button to start dispensing the
pre-selected volume.
The system will automatically stop once the requested volume is reached.
Water Quality values
When the dispensing is nished, the resistivity and temperature are instantly displayed on
the left side of the HMI. Ninety seconds later a new TOC value at the point of distribution is
indicated.
The corresponding LED lit green if the water quality te the requirements.
If the calculated TOC value is from 0 to 5
ppb, ≤ 5 ppb will be displayed
If the calculated TOC value is from 6 to 10 ppb,
≤ 10 ppb will be displayed
For values upper to 10 ppb, a rounded value will be displayed.
Dispense archiving
Water quality values of each dispense are automatically archived and can be retrieved in the
history report section available in the information menu. Go to page 10 Information > History
for further information.

Accessories
Water sensor
A water sensor can be connected to the system unit to stop
the system from producing water in case of water spillage.
Foot pedal
The pedal is connected to the system.
In the HMI conguration app, activate the foot pedal via the
slider button.
Dispense using the foot pedal
1. Press once and release to dispense in full ow.
2. Press once to stop the ow dispensing.
Feed water conductivity sensor
A conductivity sensor can be installed inside the system to
monitor the feed water quality entering the system from the
loop. If bad water quality is detected, an alarm that stops
water production will appear, informing the user that the
system is at risk and to check the feed water quality. This
will protect the downstream purication technologies in case
of a problem. This accessory is not meant to be used with
deionised feed waters.
Inlet Pressure Regulator
This accessory will allow to regulate the pressure of the
water entering the system from the loop. This will protect the
downstream elements from high water pressure. It is highly
recommended to use this regulator instead of an external
pressure regulator on the feed water tubing.
Alarm relay
This accessory will allow to relay all, or a selection of
alarms to a remote device.
Select the alarm(s) that will activate the relay.

Settings 15
Alarm set points
Adjust the alarm set points by either clicking on the arrows or alternatively, click in the box to
access the keypad and directly type-in the value.
Water quality
• Product resistivity/conductivity
• Product TOC
Inlet strainer clean
This is only applicable when set-up in Loop conguration. It is recommended to clean the inlet
strainer once a year to avoid clogging. Depending on the feed water and its particle concentra-
tion, the inlet strainer clean frequency can be adapted.
Cartridge lifetime
Cartridges should be changed when the system alerts the user.
Saturated pack will start to let ion and organic contaminants through. This is called breakthrough
and often starts with traces that cannot be detected by on-board monitoring. Some technologies
will clog, creating a back pressure which can result in ow-rate issues.
In validated settings, to adjust lifetimes according to existing SOPs, click on the applicable
lters and adjust accordingly.
• IPAK polishing cartridges
• POD-Paks
Connectivity
The system oers the possibility to be connected to a laptop with a xed IP address or to your
local network (DHCP protocol/xed IP address) via an Ethernet port.
The IP address of the system can be seen by swiping the screen top to bottom.

Settings 16
The DHCP (Dynamic Host Conguration Protocol) is an “automatic conguration” of a device anytime
it connects to an IP Network. This “automatic conguration” is called allocation. The system is
automatically recognized and an IP address is assigned to it. and congured so that the networks
resources can be used. Check with your local IT resources which type of connection is best suited to you.
Change network connection settings
1. For a direct connection, change the network settings if necessary
(default IP address: 192.168.1.69).
2. For network connection, activate DHCP via the DHCP activation button.
Duplicate user interface in a browser
Once connected:
1. Go to your browser. For best browsing performance, Chrome® is recommended.
2. Enter the IP address of your system which can be found in the connectivity pop-up screen.
Note: The view from a laptop enables a user to view the HMI display remotely. Dispensing
operations cannot be conducted remotely for safety reasons.
Date Time & Language

indicates a four-digit year. [MM] indicates a two-digit month of the year, 01 through 12. [DD]
indicates a two-digit day of that month, 01 through 31.
Start by setting the year:
1. Click on the month & year title, this displays months and only the year as a title. Click again
on the year title to display years.
2. Select the year, this then displays months.
3. Select the month, this then displays the days.
4. Finally select the day to conrm the date setting.
Time ZONE
1. Select the continental or oceanic zone you are in on the left. This updates the right-hand
side with all the major cities within this time zone.
2. Select the appropriate city. If you have not found a city, make sure you are in the right time
zone.
The Milli-Q® system is now congured to display current local time and automatically updates
when daylight saving time applies.
Time
The time is set and displayed in a 24h clock format. A time of day is written in the 24-hour
notation in the form hh:mm (for example 14:23), where hh (00 to 23) is the number of full hours
that have passed since midnight, mm (00 to 59) is the number of full minutes that have passed
since the last full hour.
Language
There are 9 languages available: Chinese / English / French / German / Italian / Spanish /

Units
Units can be formatted to local needs:
Resistivity / Conductivity MΩ.cm µS/cm
Temperature °C °F
Storage tank level L %
Pressure Bar / kPa / psi
Select and press on the unit of interest. The selected unit will appear in blue. Press “OK” to
conrm selection and exit the pop-up.
Temperature compensation mode
It is possible to show non-temperature compensated resistivity or non-temperature compensated
conductivity. Temperature compensation is a way of standardizing resistivity or conductivity to
measurements that would be seen if the water temperature was 25°C.
Select the preferred mode among the 3 modes of temperature compensation available:
TC1
By default TC1 mode is selected.
The resistivity or conductivity values are temperature compensated to 25°C.
The values are normalised. The system rmware eliminates small uctuations of
temperature compensated resistivity or conductivity due to the fact that these two
parameters are not measured exactly at the same time.
TC2
The actual temperature compensated resistivity or conductivity values are
displayed. The TC2 setting should be used in applications that require the detection
of trace ionic levels or when performing the verication of the system resistivity
meter operation with an independent calibrated resistivity meter. In some operating
conditions the feed water can be warmer or cooler than the water temperature
inside the system. As a result, this can cause small uctuations of the resistivity
and conductivity values. Resistivity values could uctuate between 18.0 Mohms.cm
and 18.4 Mohms.cm @25°C while the actual resistivity is 18.2 Mohms.cm @25°C.
NTC
Non Temperature Compensation. The temperature compensation is o. The displayed
resistivity or conductivity is not temperature compensated. The temperature of the
water is shown at the same time as the non-temperature compensated resistivity
or conductivity value.
