Main Power SwitchThe main power switch on the EASYpure UF is located onthe back right of the unit (as you face the front of the unit),directly above the power cord receptacle. This switch mustbe on for the unit to operate.

Control PanelThe EASYpure UF is controlled through a control panelwhich incorporates three button switches, three indicatingLED’s and a digital display.

SwitchesThe three switches on the control panel function as follows:

Start/StopWhen the main power switch is on, pressing the START/STOP switch will start the pump and energize the display,.When the EASYpure UF is in Standby mode, pressing theSTART/STOP switch will return the unit to run mode. (SeeModes below.)

StandbyWhen the EASYpure UF is in run mode, pressing theStandby switch will place the unit in Standby mode. (SeeModes below.)

FlushWhen the main power switch is on, pressing the Flushswitch once will initiate a one minute flush of the ultrafilter.During this one minute flush, water is sent to drain throughthe reject tubing, the Manual/Extended Flush LED will belit, and the display will be dark. If you press the Flushswitch twice , the EASYpure UF will initiate a five minuteflush. During this five minute flush, water is sent to drainthrough the reject tubing, the Manual/Extended Flush LEDwill flash, and the display will be dark. We recommend theyou initiate a one minute manual flush when starting up theEASYpure UF prior to your day’s work.

Principles of Operation

15

DisplayWhen the EASYpure UF is in run mode, the display indi-cates the purity (in megohms-cm) of the water available fordraw off. When the EASYpure UF is in Standby mode, thedisplay will be dark and the Standby LED will be lit. Whenthe EASYpure UF is in a Flush mode, the display will bedark and the Manual/Extended Flush LED will be lit or flash.If the display indicates anything else, see the Troubleshoot-ing section of this manual.

Operational Modes

Run and Standby ModesSince not all qualities of permissible feedwater will reachmaximum resistivity after one pass through the unit’s car-tridges (especially as the cartridges near exhaustion), theEASYpure UF has two operational modes.

In the run mode, the pump continuously recirculates waterthrough the cartridges. This is the mode that the unit entersupon startup. If water will be drawn from the EASYpure UFon a continuous basis throughout the day, it is recom-mended that the EASYpure UF be left in the run mode. Inthe run mode, the purity meter display indicates the resistiv-ity of the water available for draw off.

In standby mode, the pump runs for ten minutes out of everyhour (i.e. ten minutes on, fifty minutes off). If water will bedrawn from the unit only infrequently, it is recommended thatthe unit be put into standby mode. To put the unit intostandby mode, press the “STANDBY” switch on the front ofthe unit. The display will be dark and the Standby LED willbe lit when the EASYpure UF is in Standby mode.

Automatic FlushIn both run and Standby modes, the EASYpure will initiate aone minute automatic flush of the ultrafilter once everytwenty-four hours of operation. This prevents bacterialbuildup on the ultrafilter. A solid-state timer in the EASYpureUF counts the hours power is applied to the unit. When thetimer reaches twenty-four hours, the EASYpure UF initiatesa one minute flush, the Automatic Flush LED is illuminated,and the timer resets to zero.

PRINCIPLES OF OPERATION

16

NoteIf the EASYpure UF is wall mounted,remove the power cord and rotate theEASYpure UF until the cartridgeaccess door faces forward and theEASYpure UF locks into place.

NoteA small amount of water will drain fromthe cartridge when it is disconnectedfrom the lower socket. Plug thecartridge’s lower opening with yourfinger to minimize water spillage whileyou finish removing the cartridge.

NoteUsed cartridges may be recycled. SeeP.U.R.E. information packed with newcartridges.

22

0.2 Micron Filter ReplacementReplace the 0.2 micron final filter whenever any of thefollowing conditions occur: every 30 days, theproduct water flow rate is reduced or bacteria breakthrough. The 0.2 micron filter is shipped assembled with abell. To replace the 0.2 micron filter assembly:

1. Remove the old 0.2 micron filter assembly byturning it counterclockwise until it is free from theLuer fitting.

2. Remove the new 0.2 micron filter assembly fromits bag and insert it into the Luer fitting. Gently turnit clockwise until it is fully seated in the Luer fitting.

3. Rinse 10-15 liters of water through the filter todrain prior to using the product water.

System SanitizationFrequency of cleaning is difficult to determine because ofvariability in feedwater and usage. Sanitization is recom-mended when cartridges are replaced or if a new 0.2 micronfilter clogs rapidly after installation even though the car-tridges were properly rinsed before the 0.2 micron filter wasinstalled. To sanitize the EASYpure UF, the purificationcartridges must be replaced with a sanitization cartridge andtwo empty cartridges. The simple to use sanitization car-tridge is available from Barnstead|Thermolyne (Part#D50245). This is used in addition to the empty cartridgesincluded with this unit to effect a complete sanitization.

1. Turn the EASYpure UF off. Depressurize thesystem by opening the outlet valve. When waterstops flowing from the draw-off valve, the systemis depressurized.

2. Disconnect the unit from the power supply.

3. Remove the 0.2 micron final filter. Open thecartridge access door in the rear of the unit.Remove the purification cartridges and replacewith empty cartridges. Place a D50245 sanitizationcartridge in the first position and install the emptycartridges in the other two positions. Close thecartridge access door.

MAINTENANCE AND SERVICING

CautionDo not overtighten the 0.2 micron filterassembly onto the Luer fitting or useexcessive force in seating it. The filterand/or Luer fitting can be damaged byovertightening or excessive force.

NoteIf a newly installed 0.2 micron filterclogs rapidly after installation, theEASYpure UF may need to be sani-tized to remove bacterial contami-nants. See System Sanitization .

23

This device is to be used with water feeds only. Sanitiz-ing/cleaning agents must be used in compliance withinstructions in this manual. Failure to comply with theabove could result in explosion and personal injury.

4. Connect power to the EASYpure UF. Press the“Flush” button twice to begin an extended flush.

5. When the extended flush stops (5 minutes),open the draw-off valve. Press the “START”button. Draw off 2.0 liters of solution throughthe draw-off valve. Close the draw-off valve.Discard the solution.

6. Recirculate the disinfectant solution for approxi-mately 30-45 minutes. Then open the draw-offvalve, directing the output to drain.

ConsumablesConsumable parts are those required to support the day-to-day operation of this equipment.Barnstead|Thermolyne establishes two types of consumables; those items that must periodically be replaced tomaintain performance (filters, resin cartridges, etc.) and other items of limited life (indicator lights, fuses, etc.)that you can expect to replace on a more or less random basis. Where practical, Barnstead|Thermolynerecommends the frequency of replacement, or provides information on life expectancy from which you maycalculate a replacement interval compatible with your usage pattern.

The replacement of consumable parts is discussed in the “MAINTENANCE and Servicing” section to assist youin accomplishing your own service.

Consumables may be ordered separately and in some cases, as an expendables kit. Check with yourBarnstead|Thermolyne representative for additional information on the expendables kit.
