INTRODUCTION

General Information

The Autopure WR600 system is used as a final step of water purification. The feedwater to a Autopure WR600 system can come from electrodeionisation (ELIX), Reverse Osmosis (RO), distillation or demineralisation.

The Milli-Q system produces water of Type 1 quality. This is equal to or better than ASTM, CAP and NCCLS water quality standards.

How the system works

Pre-treated water (from EDI, Reverse Osmosis, distillation or demineralisation) enters the system and is pumped through the Q-Gard pack for an initial purification step.

The water is then exposed to UV light at both 185 and 254 nm wavelengths which oxidises organic matter and kills bacteria.

The function of the QUANTUM cartridge is remove ions produced from the action of the UV light.

Purified water then passes through an Ultrafiltration (UF) module. The UF module acts as a barrier to colloids, particles and other organic molecules with a molecular size higher then 5000 Daltons. The contaminants retained by the UF are periodically flushed out of the system via tubing to a drain.

A manual 3 way valve directs ultrapure water through a final filter made up of a 0.22 um membrane (MilliPak-40). The final filter prevents particles and bacteria greater than 0.22 um in size from being dispensed from the system.

The A-10 TOC monitor takes a sample of ultrapure water and determines the trace levels of organic material in it. The samples are taken periodically in PRODUCT mode. Because of the sampling frequency, the displayed water quality is representative of an instantaneous value.

lTest conditions: Autopure WR600 was equipped with a Q-Gard pre-treatment pack and a QUANTUM EX cartridge. The feedwater to the Autopure WR600 came from a RiOs Reverse Osmosis system. TOC levels in the feedwater were < 50 ppb. The quality of the Autopure WR600 product water can vary as a function of the quality of the feedwater.

Installation of the system

The system can either be placed on a bench or wall mounted. If the system is to be wall mounted, then it is necessary to first verify that the wall can support the weight of the system. Contact Yamato Technical Service for further instructions on wall mounting the system.

Some versions of the Autopure WR600 systems require a drain nearby. When a reservoir is used as a feedwater supply, locate the system and reservoir close together whenever possible.

Note: The pressure regulator and pressure gauge are not supplied with the Autopure WR600 and must be ordered separately. Contact Millipore Technical Service for more information.

Installation

Connection of feed water to the system (Figure 3)

System fed from a reservoir :

1.Cut the feed water tubing, 8 mm OD (Figure 2, D) to the desired length (< 2.5 meters)

2.Remove the protective plug (B) from the “FEED 1” connection (H) by pressing on collar (A) and pulling the plug out.

3.For wall mounting of the system, install elbow connectors (figure 2, J).

4.Connect the feed water tubing (C) (8 mm OD) to inlet “FEED 1”(H) by inserting it firmly in the fitting. Verify that the connection is correctly made by pulling several times on the tubing once inserted.

5.Connect the other end of the feedwater tubing to the reservoir at an appropriate location ( Figure 5).

System fed from a pressurised source :

1.Cut the feed water tubing, 8 mm OD (Figure 2, D) to the desired length (< 2.5 meters)

2.Remove the protective plug (B) from the “FEED 1” connection (H) by pressing on collar (A) and pulling the plug out.

3.The feed water valve or the fitting (D) should terminate in a 1/2” MNPT fitting.

The 1/2” FNPT fitting (E) is screwed on to the fitting (D). Use the Teflon tape (Figure 2, I), which is supplied with the unit, to ensure a good seal against leaks.

4.Connect the tubing (C) to the fitting (F). Pull on the tubing afterwards to insure it is secure.

5.Pressurised feedwater entering the Milli-Q system must be regulated between 0.2 Bar (3 psi ) and 0.5 Bar

(7 psi) . Installation of a pressure regulator is necessary if the feedwater pressure is over 0.5 Bar (7 psi). The

regulator should be adjusted while water is dispensed from the system.

Connection of the reject tubing(s) (figure 3).

Any Autopure WR600 system with the A-10 TOC or UF option(s) has to have reject tubing on the system. The procedure to connect the reject tubing is the same as that used for the feed water tubing.

1.

Connect the Ultrafiltration cartridge reject tubing (8 mm OD) (Figure 2, D), < 2.5 m to the “DRAIN 3” (I) outlet.

2.

Connect the A10 waste stream tubing (6 mm OD) (Figure 2, E), < 2.5 m to the “OUT 5” (J) outlet.

Note: If the Autopure WR600 System is fed by a reservoir, the A10 reject water can be recycled.

When starting up the system, place all the ends of all reject tubing(s) to the drain.

Installation of the Q-Gard purification pack (Figure 4)

(The Q-Gard is only used on Autopure WR600 systems equipped with a pack adapter)

1.Raise the pack adapter (A) to its highest position. Remove the two protective plastic inserts (B) on the pack adapter.

2.Remove the two protective inserts on the Q-Gard pack (C). Wet the two O-rings with water.

3.Push the Q-Gard so that the pack adapter metal rod (D) goes through the hole at the top of the Q-Gard.

-Lift the Q-Gard slightly and push the bottom of it into the small opening (E) on the system.

-At the upper pack adapter, push the pack completely in until secure.

4.Lock the Q-Gard in place with the metal locking clip (F) clip on the end of the metal guide pin (D).

5.Bring the adapter cap down to its lowest position (G) so that it covers the top of the Q-Gard.

Electrical connection of system

1.Connect the power cord (Figure 2, B) to the Autopure WR600 (Figure 3,L). Connect the other end of the power cord to an earth grounded power source.

2.Check that the point of use gun trigger is in the up-right position.

3.Turn on the system electrical switch (figure 1, H) by putting it to position I.

4.The serial number is displayed Note the serial in the table below.

Note : Contact Yamato Technical Service when connecting a level sensor to the Autopure WR600 system. As an option, it is possible to get a “NO FEED WATER” message when there is no water in the reservoir.

Installation of the QUANTUM Polisher Cartridge (Figure 4)

1.Open the blue door on the front of the Autopure WR600 by pressing the 2 latches (H) on the door to the left to open it.

2.Remove the two protective inserts from the QUANTUM cartridge. Wet the two rubber O-rings on the QUANTUM polisher with water.

3.Install the QUANTUM polisher. Push it straight in so that the QUANTUM is fully inside.

4.Close the door. It is necessary to fully snap the latches (H) shut to hold the QUANTUM cartridge inside.

Rinsing the Autopure WR600 for the first time

A 5 minute rinsing cycle “AIR PURGE” occurs automatically whenever new cartridges are installed in the Autopure WR600 system.

1.Open the feedwater isolation valve if there is one.

2.The system will be waiting to begin the AIR PURGE cycle.

3.Start the AIR PURGE by moving the point of use gun trigger forward. Direct all water from the point of use to a drain.

4.At the end of 5 minutes the system will go into PRODUCT mode. Close the point of use gun trigger (bring it vertically straight up).

5.If possible, leave the system in PRE-OPERATE mode overnight. This helps to hydrate the ion exchange resin inside the cartridges.

6.In PRE-OPERATE mode, purge the QUANTUM cartridge of any trapped air by pushing in on the small hole located on the blue door (figure 4, K).

7.Quickly push in a small screwdriver into the hole to purge out the trapped air.

Cleaning the A-10 measurement cell.

When a Autopure WR600 system is configured as an A-10 model, an automatic cleaning of the A-10 analysis cell takes place. This cleaning lasts for 1 hour.

Connection of an RS 232 interface with the system.

The Autopure WR600 system offers the possibility of transmitting information to a printer. It can be done by in MENU mode in the MEASURE section.
