Introduction The Barnstead EASYpure UV/UF is a line-fed water purification system designed to provide pyrogen-free, low TOC reagent grade water that exceeds ASTM, Type I, Type A and NCCLS Type I standards. It uses a threestage deionization process combined with UV oxidation, a 10,000 molecular weight cutoff ultrafilter and a 0.2 micron filter to polish pretreated water (distilled, deionized, or reverse osmosis) to produce pyrogen-free (<0.005 EU/ml), low TOC (<2 ppb) water with a resistivity of up to 18.
General Specifications Dimensions and Clearance Requirements EASYpure UV/UF dimensions: 12 " W X 19" D X 17 1/8" H (30.5 cm X 48.3 cm X 43.5 cm). Clearances: Sides: 4" (10.2 cm) minimum to allow air flow. Above: 12" (30.5 cm) minimum for removal of the top cover. Cartridge replacement requires that you be able to access the back of the unit and open the cartridge access door (total depth, unit + open door, = 34" (86.4 cm)).
GENERAL SPECIFICATIONS Environmental Conditions Operating: 4°C - 49°C; 20% - 80% relative humidity, non-condensing. Installation Category II (over-voltage) in accordance with IEC 664. Pollution Degree 2 in accordance with IEC 664. Altitude limit: 5,000 meters. Storage: -25°C - 65°C; 20% to 80% relative humidity.
Unpacking and Installation Unpacking 1. Remove the unit from its shipping container. Ensure that the ultrafilter, UV lamp, feed and reject tubing, final filter, sanitization cartridge and power cord are removed form the packaging materials before discarding. Tubing Adapter Installation The following instructions will apply when you need to attach a piece of tubing to your EASYpure UV/UF during installation, unless otherwise noted in the installation instructions. To make tubing connections: 1.
INSTALLATION Caution Do not tighten tube fitting hex nut with a wrench. Tight connections can be easily made by hand. Warning Depressurize system prior to opening cartridge access door. Warning A small amount of 2.0% hydrogen peroxide is used to preserve the ultrafilter during storage. When removing the ultrafilter from the bag, ensure adequate ventilation and wear protective gloves and glasses. 3. Place the grab ring and back-up ring in the hex nut in the order and orientation shown in Figure 3.
INSTALLATION you. Viewed this way, the product connector is the one on the left. The reject connector is the one on the right. (See Figure 5) Remove the nut, stainless steel grab-ring, backup ring and o-ring from each of the ultrafilter connections and discard. 5. The three pieces of tubing that you disconnected from the “T” in step 2 are the Feed, Reject and Product lines for the ultrafilter. The Reject and Product tubing nuts are labeled; the unlabeled one is the Feed line.
INSTALLATION Caution Do not unscrew the cover, as this will loosen the water tight seal and thus damage the UV lamp. Caution Do not touch the glass portion of the UV lamp. We recommend that you wear lint-free gloves when handling the lamp. The glass portion must be free of fingerprints, perspiration, etc. Even a single fingerprint will reduce the effectiveness of the lamp. If you accidentally touch the glass portion of the lamp, clean the lamp with a lint-free cloth; use isopropyl alcohol if required.
INSTALLATION Wall Mounting (Optional) Note The outlet of a gravity feed storage reservoir must be above or at the same level as the inlet of the EASYpure UV/UF. Caution Wall composition, condition and construction, as well as fastener type, must be considered when mounting this unit. The mounting surface and fasteners selected must be capable of supporting a minimum of 120 lbs. Inadequate support and/or fasteners may result in damage to mounting surface and/or equipment.
INSTALLATION Reject Water Connection When the EASYpure UV/UF flushes its membrane, the water used is sent to drain through this connection. To install: 1. Locate the reject water tubing. This is the piece of 1/4” O.D. tubing that has an adapter on one end and no connector on the other end. Remove the nut, grab ring, backup ring and o-ring from the reject water fitting located at the lower right of the unit. (See Figure 3 for part identification and Figure 8 for fitting location.
Controls Main Power Switch The main power switch on the EASYpure UV/UF is located on the back right of the unit (as you face the front of the unit), directly above the power cord receptacle. Control Panel The EASYpure UV/UF is controlled through a control panel which incorporates three switches, three indicating LED’s and a digital display.
CONTROLS Pressing the Flush switch twice will initiate a five minute flush of the ultrafilter. During this five minute flush, water is sent to drain through the reject tubing, the Manual/ Extended Flush LED will flash, and the display will be dark. After the timed flush has ended, the EASYpure UV/ UF will return to the Mode (Off, Run or Standby) it was in when you initiated the flush. We recommend that you initiate a one minute manual flush when starting up the EASYpure UV/UF prior to your day’s work.
Operational Modes Run Mode Since not all qualities of permissible feedwater will reach maximum resistivity after one pass through the unit’s cartridges (especially as the cartridges near exhaustion), the EASYpure UV/UF has two operational modes. In the run mode, the UV lamp shines continuously and the pump continuously recirculates water through the cartridges, the UV chamber and the ultrafilter. It is recommended that the EASYpure UV/UF be left in the run mode during the day.
Initial Operation Initial Sanitization Warning Avoid splashing disinfecting solutions on clothing or skin. Ensure all piping connections are tight to avoid chemical leakage. Ensure adequate ventilation. Carefully follow manufacturer’s safety instructions on labels of chemical containers and material safety data sheets. This device is to be used with water feeds only. Sanitizing/cleaning agents must be used in compliance with instructions in this manual.
INITIAL OPERATION Warning Depressurize system prior to opening cartridge access door. Note If the EASYpure UV/UF is wall mounted, rotate the EASYpure UV/UF until the cartridge access door faces forward and the EASYpure UV/UF locks into place. The EASYpure UV/UF’s cartridges must be installed in the proper order. If you have just sanitized your EASYpure UV/UF, retain the empty cartridges shipped with your unit for use when you sanitize it in the future, discard the D50245 sanitization cartridge.
INITIAL OPERATION Pretreatment Cartridge D50230 10. Press the “Flush” button twice to begin an extended flush. When water begins exiting the system, close the draw-off valve. 11. When the extended flush ends, press the START/STOP button to stop and depressurULTRApure Cartridge ize the system by opening the draw-off D50233 valve and allowing water to drain from the unit until draining ceases. Close the drawoff valve.
Normal Operation Note On initial start-up, the purity meter may display “ERR”. This is caused by air in the cell and should be replaced by a resistivity reading almost immediately. If “ERR” does not go out after the pump has run for a minute or if it appears any time while the EASYpure UV/UF is in operation, refer to the Problem Solving section of this manual. Note For low organic and pyrogen applications, draw off 50 to 100 ml of water from system and discard prior to drawing water for each use.
Installing Float or Pressure Switch Warning Disconnect from the power supply prior to maintenance and servicing. Accessories D0606 (float switch) and D2706 (pressure switch) are designed to protect the EASYpure UV/UF pump by alerting the EASYpure UV/UF of an inadequate feedwater condition so that the pump can be shut down. Use the following instructions for installation. 1. Disconnect the unit from the electrical power. 2.
Maintenance and Servicing System Sanitization and Cartridge Replacement The frequency with which you will need to clean your unit and replace cartridges is dependent on your feedwater’s characteristics, your purity requirements and your usage. Sanitize your EASYpure UV/UF and replace the cartridges when the product water purity drops below acceptable levels of resistivity, when organic levels become too high, or if a new 0.2 micron filter was installed.
MAINTENANCE AND SERVICING Note Used cartridges may be recycled. See P.U.R.E. information packed with new cartridges. 8. Repeat steps 2 - 6 with the two empty cartridges supplied with your EASYpure UV/UF, placing them in the center and left-hand positions. 9. Close the cartridge access door. Remove the 0.2 micron filter and bell assembly. 10. Sanitize, install new cartridges and rinse according to the instructions for Initial Sanitization and Cartridge Installation in the Initial Operation section.
MAINTENANCE AND SERVICING Ultrafilter Replacement The length of your ultrafilter’s life will depend to some extent on conditions and use in your lab. When you are unable to completely sanitize your system (i.e. you can no longer get pyrogen-free water even after sanitizing the system), replace the ultrafilter as follows: 1. Turn off the EASYpure UV/UF and disconnect it from the power supply. Note Some water will drain from the ultrafilter when you disconnect it.
MAINTENANCE AND SERVICING Warning Depressurize system prior to opening cartridge access door. Caution Do not unscrew the cover, as this will loosen the water tight seal and may damage the replacement lamp. Pull the cover straight up. Note Pay close attention to the orientation of the plug as it is attached to the UV lamp. It will be necessary to ensure that the plug is installed in the same manner as removed.
