1 INTRODUCTION
This manual describes in detail about system performance characteristics,
installation, operation, and routine maintenance. Please read this manual
thoroughly for its instruction on installation, use and maintenance. Proper
installation and maintenance guarantee the continuous flow of high
quality pure 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!
To avoid electrical shock, always:
1) Use with a properly grounded electrical outlet of correct voltage and
current handling capacity.
2) Replace fuses with those of the same type and rating.
3) Disconnect from the power supply prior to maintenance and service.
4) Refer servicing to qualified personnel.

1.1 Product Features
The small footprint Accu20 lab water system is an ideal choice for users
who need up to 20 liters of ultrapure water per day. Quality of ultrapure
product water meets or exceeds ASTM, CLSI, CAP, and ISO Type I water
standards.
This system has the following characteristics:
•The compact system provides an easy way to produce Type I
ultrapure water and RO water on demand directly from tap water.
•The system installation and maintenance are very easy to perform by
a trained lab technician.
•The system is equipped with a Safeguard AccuDuo P Pack cartridge
and a dual-column AccuDuo U Pack ultra-purification cartridge to
ensure optimum quality of the final product water.
•No storage tank is required, which eliminates the risk of potential
contamination and bacteria growth inside a tank.
•The fully automatic controlled and maintained system contains
automatic cleaning cycles and self-maintenance functions for the RO
membrane, which increases the lifetime and efficiency of the RO
membranes as well as the cartridges.
•Automatic hourly system recirculation in the loop prevents bacterial
growth and maintains water purity at all times.
•System status and key quality parameters are clearly displayed on a
large LCD screen for easy monitoring of system performances.

1.2 Main Applications
Pure water can be used in many areas. Here are some typical
applications.
•HPLC mobile phase preparation
•Preparation of reagent blank solutions
•As sample diluents for GC, HPLC, AA, ICP-MS and other analytical
techniques
•Preparation of buffer and culture media for mammalian cell culture
Preparation of molecular biology reagents, etc.

1.4 Operation
Accu20 water systems produce ultrapure water and RO water directly
from tap water. Tap water is pretreated through a Pretreatment Cartridge
(AccuDuo P Pack) to reduce free chlorine, larger particles and water
hardness. Then most particles, ions and organic compounds are removed
through the RO membrane. RO water flows through an ultraviolet UV light
chamber (optional) to kill bacteria and destroy trace organic pollutants in
water. Then water flows through a polishing cartridge U pack to remove
the last traces of ions, finally, a 0.2 µm filters to the outlet.
After powering-up, press START button to initiate the system. After a
180-second automatic RO flush, the system goes into READY mode.
Press the RO button to start a 60-second cleaning cycle and dispense
RO water. Press the RO button again to stop the dispensing. Press the
UP button to start a 60-second cleaning cycle and dispense ultrapure
water. Press the UP button again to stop the dispensing.
