1 INTRODUCTION
The system is designed to produce ultrapure water (Type I) and EDI (Type II) water directly from
tap water. Water quality produced meets or exceeds the corresponding ASTM, CAP, CLSI and
ISO 3696 / BS 3997 water standards.
This manual describes in detail system performance characteristics, installation, operation, and
routine maintenance. Please read this manual thoroughly for its instructions on installation, use
and maintenance. Proper installation, use and maintenance guarantee the continuous flow of
high-quality ultrapure water.
Please contact us or your local distributor if you encounter any issues during installation and use.
Professional engineers are fully trained to support you.
Safety Information
WARNING!
1) Always power down the system before plug or unplug any hardware. Never hot swap
(hot plug) any hardware, including dispenser, monitor as it may damage control
boards.
2) Disconnect the unit from the power supply prior to doing service work. Refer service to
qualified personnel.

Description of the system
The VWR G water system manages the production and distribution of ultrapure water from tap
water. It consists of three main units:
◆Main System: manages the production of ultrapure water.
◆Dispenser: integrates the touchscreen and manages the dispensing.
◆Control Console: controls and monitors the water system and other components on the 8-inch
touchscreen.

7vwr.com I Instruction manual VWR® G Water System
1.2 Product Features
The VWR G ultrapure water system provides an integrated solution for lab water supply. This
system is easy to install, easy to operate and easy to maintain.
This system has the following features:
◆Type I ultrapure water and EDI (Type II) water are produced directly from tap water.
◆The system can be linked to multiple dispensers via cable or wireless.
◆Internal P Pack cartridge removes oxidants, organics, particles and scaling ions to prevent
them from fouling the RO membranes and the EDI module.
◆Alarm will lit if RO permeate does not meet preset quality standard (SP) to protect the EDI
module.
◆The RO drain water is reused to increase the water yield. It is more environmentally friendly.
◆Internal Ion-Pure EDI module removes most ions and organics from RO water.
◆Ultra purification cartridge is filled with media to remove trace ions and organics.
◆Built-in 254 nm lamp kills bacteria and 185/254 nm dual-wavelength lamp reduces TOC level
in ultrapure water.
◆On-line TOC monitor is based on complete oxidation method to obtain a more accurate
measurement of the TOC.
◆Various final filters (optional) can ensure ultrapure water without particles, bacteria or
pyrogen.
◆Tank recirculation mode (optional) from a touch on the monitor guarantees high water quality
in storage.
◆RFID tags ensure perfect placement of consumables and trace their performance.
◆The control console is an 8-inch touchscreen. The console controls system and peripheral
devices (such as dispensers and tank sanitization module). All operations can be done on
the console.
◆Water quality, operation parameters, the status of the system, dispensers, components, and
peripheral devices are stored and displayed on the large colour touchscreen monitor.
◆The console screen and dispenser screens are water-proof. You may operate the console
and dispenser with wet latex gloves on.
◆Signature verification is required for maintenance and service.
◆VWR provides full documents support to meet user’s GMP, GSP, GAP, GCP, GLP
requirements.

1.5 Operation Principles
VWR G water system produces ultrapure water and pure water directly from tap water. Most
particles, ions and organic compounds are removed through the pre-filtration, RO membrane, EDI
module, then the EDI water flows through a UV chamber to be sanitized before going to the
storage tank. When in need of ultrapure (UP) water, EDI water goes through a UV lamp chamber
with a dual-wavelength UV lamp to destroy trace organic pollutants in water, then through a
polishing cartridge to remove the last trace of ions, then a 0.2 μm final filter to the outlet.

2.4.3.3 Installation
Follow the steps below if the diameter of the faucet is 1/2inch male thread.
a) As the picture shown above, connect the inlet of the feed valve to the faucet.
b) Cut an appropriate length of 8 mm PE tubing. Insert one end of the tubing into the port
Tap Water In on the main system and the other end into the outlet of the feed valve.
c) Place the sensor metal probes side down at a lower point on the floor or near the water
system.
d) Plug the terminal of feed valve into the port Feed Valve on the back of the main system,
and plug the terminal of leak sensor into the port Leak Sensor.
Follow the steps below if your system is equipped with a prefiltration device.
a) As the picture shown above, connect the inlet of feed valve to the faucet.
b) Cut an appropriate length of 8 mm PE tubing. Insert one end of the tubing into the inlet of
prefiltration device and the other end into the outlet of the feed valve.
c) Similarly, cut another appropriate length of 8 mm PE tubing. Insert one end of the tubing
into the port Tap Water In of the main system and the other end into the outlet of the
prefiltration device.
d) Place the sensor metal probes side down on the floor or near the water system.
e) Plug the terminal of feed valve into the port Feed Valve on the back of the main system,
and plug the terminal of leak sensor into the port Leak Sensor.
2.4.3.4 Instruction for use
The leak protector will be activated automatically once the system powers up.
When water is detected by the leak protector, the system will shut the Feed Valve down, and
switch to Standby mode automatically. A red icon will appear on the screen and an alarm
message box will pop up. The message “Leak or Tank Overflow, all valves are closed,
system could run after troubleshooting” will disappear by tapping Confirm when the leak
is resolved. Switch system from Standby to Ready mode manually so system will work again.
