Product OverviewThe Barnstead EASYpure RODI is a tap-fed water purificationsystem designed to be simple to use and to provide reagentgrade water that exceeds ASTM, Type I, and NCCLS/CAPType I standards. It uses a thin film composite reverse osmo-sis membrane with one stage of pretreatment to produce ROwater that is then polished using a two-stage deionizationprocess combined with UV oxidation and a 0.2 micron final fil-ter.

The % rejection between incoming and reverse osmosis prod-uct water is monitored and an indication is provided to theuser if the RO water quality is unacceptable. RO membranepressure is provided by a pressure gauge located on the rightside of the unit. The DI water resistivity is continuouslysensed by a resistivity cell and displayed on a digital displayin megohms-cm.

RO operation is automatic and works independently of the DIsystem to fill the EASYpure RODIʼs self-contained 6.5-literreservoir as determined via the position of 3 floats in thereservoir.

The EASYpure RODI is not shipped with a reverse osmosismembrane, cartridges or final filter. These must be orderedseparately. The start-up kit containing these components canbe ordered using part number D502132.

The EASYpure RODI is designed to be a bench mounted unit.If wall mounting is required, refer to “Locating the Unit” onpage 18.

Control PanelThe EASYpure RODI control panel incorporates threeswitches, a digital display and three LEDs.

Switches (See Fig. 12)When the main power switch is on, the three switches onthe control panel function as follows:

1. START/STOP: When the unit is in the Idle Mode(“IdL”) or Standby Mode (“SbY”), pressing theSTART/STOP switch will put the DI operation ofthe unit in the Run Mode, turning the DI pumpand UV lamp on. The RO operation will auto-matically turn on in Run Mode to fill the tank asneeded. When the unit is in the Run Modepressing the START/STOP switch will put theRO and DI operation of the unit into the “IdL”Mode. When the unit is in any of the flushmodes, pressing the START/STOP switch willreturn the unit to the mode it was in just prior towhen the flush was initiated.

2. STANDBY: Pressing the STANDBY switch willplace the DI operation of the unit in STANDBY(“SbY”) Mode from either the Run Mode or the“IdL” Mode. Pressing the STANDBY switch whilethe unit is in STANDBY (“SbY”) mode has nofurther effect. The RO operation will automatical-ly turn on in STANDBY (“SbY”) Mode to fill thetank as needed. When the unit is in STANDBY,water will recirculate for 10 minutes every hour.

Pressure GaugeThis unit includes a pressure gauge to monitor the ROmembrane pressure. The pressure gauge is located onthe lower right side of the unit. A pressure of 65 psi (4.5bar) is ideal for operation of the membrane; lower pres-sures produce less RO product water quantities (slowerfilling of reservoir) and higher pressures produces moreRO product water quantities (quicker filling of reservoir.)

Operational ModesSince not all qualities of permissible feedwater will reachmaximum resistivity after one pass through the unitʼs car-tridges (especially as the cartridges near exhaustion), theEASYpure RODI has two operational modes; Run andStandby.

Run ModeIn the Run Mode, the pump recirculates water through thecartridges and the UV lamp. It is recommended that theEASYpure RODI be left in the Run Mode during the day.In the Run Mode, the purity meter display indicates theresistivity (temperature compensated to 25°C) of thewater available for draw off.

1. From “IdL” press the START/STOP button tostart. The EASYpure RODIʼs pump will begin torun and display the resistivity of the water inmegohm-cm.

2. Allow the waterʼs resistivity to rise to thedesired purity before drawing off water.

Also in the Run Mode, the RO operation automaticallyturns on to fill the reservoir tank as needed.

Standby ModeIn Standby (“SbY”) Mode, the pump will operate for tenminutes out of every hour (i.e 50 minutes off, 10 minuteson), during which time the display reads “rEC” which indi-cates recirculation. Every fourth time that the pump turnson, the UV lamp will also turn on for 10 minutes (i.e 3hours 50 minutes off, 10 minutes on). This will allow the

CONTROLS AND NORMAL OPERATION

NoteIf the unit is in Standby and power tothe unit is turned off or lost, the unitwill return to Standby once power isrestored.

NoteDo not put unit into Idle Mode orturn off the EASYpure RODI duringnon-work hours. Doing so will allowbacterial growth and other contami-nation of the water in the system.As a result, the system will requirea lengthy rinse-up period at thebeginning of the work day toachieve high-quality product water.

NoteWhen the unit is first put in the RunMode, the display will show 10.0 fora few seconds. This is an arbitrarynumber that indicates the unit is run-ning. Any number that appears after10.0 indicates purity.

unit to produce high quality water quickly upon beingplaced in the Run Mode and prolong the life of the UVlamp. It is recommended that the EASYpure RODI beplaced in the Standby Mode during non-work hours. Atthe end of the work day, press the STANDBY switch toplace the unit in Standby Mode. “SbY” will appear on thedisplay. Also in the Standby Mode, the RO operation auto-matically turns on to fill the reservoir tank as needed.

Flush ModeManual Flush (RO Membrane)Pressing the Flush switch once will initiate a one minuteflush of the RO membrane. During this one minute flush,water is sent to drain through the drain tubing and the dis-play will show FL1. Pressing the Flush switch twice willinitiate a five minute flush of the RO membrane. Duringthis five minute flush the display will count down FL5,FL4, FL3, etc. After the timed flush has ended, theEASYpure RODI will return to the mode (“IdL”, Run or“SbY”) it was in when you initiated the flush.

Automatic Flush (RO Membrane)In the Run Mode, the EASYpure RODI will initiate a oneminute automatic flush of the RO membrane once everytwenty-four hours of operation. This prevents buildup onthe RO membrane. A microcontroller timer in theEASYpure RODI counts the hours power is applied to theunit. When the timer reaches twenty-four hours, theEASYpure RODI initiates a one minute flush if the unit isin the Run and Standby Modes. If the unit was inStandby, the automatic flush will occur immediately afterthe START/STOP switch is pressed and Run Modeentered. The timer will reset to zero when the one minuteautomatic flush is completed.

Idle Mode (“IdL”)“IdL” indicates the unit is powered and waiting to beplaced in Run, Standby or Flush Mode.

recommended to replace RO carbon prefilter whenreplacing the RO membrane.) (See “To ResetCarbon Prefilter Timer.”)

2. Turn off the EASYpure RODI and disconnect it fromthe power supply. Remove power cord.

3. Depressurize the system by opening draw-off valveand allowing water to drain from the unit until drain-ing ceases.

4. Disconnect inlet feedwater connection.

5. Place unit such that reservoir drain is over a sink,remove lower rear drain plug and allow reservoir tocompletely drain.

6. Remove the Ventgard cap.

7. Remove the screws securing the EASYpure RODItop cover.

8. Remove the top cover by lifting straight up.

9. Locate the RO membrane and carefully unhook thetwo springs that secure it.

10. Remove the old membrane by disconnecting thereject and product tubing from the top of the mem-brane and the feed water connection from the bot-tom. See page 11 for tubing removal instructions.

11. Remove the new RO membrane (FL1332X2) fromits packaging. Note the location of the FEED,PRODUCT and REJECT connections on the hous-ing. The correct orientation for the installed mem-brane will be vertical with the FEED connectiondown.

12. Locate the three unconnected tubes labeled FEED,PRODUCT and REJECT.

The0.2 micron final filter is shipped assembled with a bell. Toreplace the 0.2 micron final filter assembly:

1. Remove the old 0.2 micron final filter assemblyby turning it to the left to unscrew it from thedraw-off valve.

2. Remove the new 0.2 micron final filter assem-bly from its bag and insert it into the draw-offvalve. Gently tighten, turning the filter to theright.

3. Open the draw-off valve and flush at least 3liters (1/2 reservoir volume) of water throughthe 0.2 micron final filter.

Ventgard Cap ReplacementThe purifying media and filter in the Ventgard filter ele-ment have a limited capacity. Therefore, the Ventgard capshould be replaced every 120 days. The Ventgard cap isshipped as a complete unit; replacement involves simplyremoving the new Ventgard cap from its plastic storagebag and placing it on the reservoir. A Ventgard cap can bestored in a cool, dry place for two years, provided its plas-tic storage bag has not been opened.

Fuse Replacement1. Turn off the EASYpure RODI and disconnect it

from the power supply. Remove the power cord.

2. Pull out the fuse drawer located in the powerentry module.

3. Remove old fuses and replace with fuses ofthe same type and rating. (See ReplacementParts section.)

4. Replace fuse drawer.
